<span style="padding-left: -9px;"><b>Resumen</b></span>
<br />
El monitoreo de la biodiversidad de mamíferos y aves en áreas naturales protegidas requiere de metodologías de campo eficientes y de herramientas de almacenamiento de datos masivos para su posterior análisis estadístico. El empleo de cámaras trampa es un método que se ha popularizado en la última década. La ventaja principal de este método es obtener mucha información de muchas especies, en poco tiempo. Una vez obtenida la información de campo dos tareas fundamentales son la organización de miles de fotos que habitualmente se obtiene durante los monitoreos, y el análisis numérico de la misma para generar diferentes estimativos a nivel de la comunidad (composición número de especies, diversidad), de las poblaciones (ocupación, abundancia, densidad) y de los individuos (uso de hábitat, actividad, forrajeo). Los objetivos de este artículo son:
<ol>
<li>comentar algunos de los recursos computacionales para la organización y extracción de la información de una gran cantidad de imágenes, y</li>
<li>comentar algunos programas y paquetes R útiles para el análisis numérico de la información.</li></span>

<span style="color:#555;font-size:160%;">Abstract</span><br /><span>La restauración de los bosques tropicales se considera cada vez más una actividad que puede contrarrestar o reducir la pérdida de biodiversidad. Sin embargo, para evaluar el éxito de la restauración pocos estudios monitorean la fauna o consideran medidas de diversidad funcional. En este estudio evaluamos, utilizando a los anfibios como grupo modelo, el efecto de un programa de restauración de bosque de niebla sobre la diversidad de especies y la diversidad funcional. Comparamos ensambles de anfibios en tres tipos de uso de suelo: áreas en restauración, bosque de niebla (ecosistema de referencia) y pastizal para ganado (ecosistema degradado) en el sur de México. Comparado con el bosque de niebla, las áreas en restauración tuvieron condiciones ambientales similares, sin embargo, la riqueza de especies de anfibios fue similar en los tres tipos de uso de suelo y la abundancia fue menor en las áreas en restauración. En el bosque de niebla el ensamble de anfibios estuvo dominado por especies especialistas de bosques, en los pastizales por especies generalistas, mientras que en las áreas en restauración hubo una combinación de ambos tipos de especies. Curiosamente, la riqueza funcional, la equidad funcional y la divergencia funcional no variaron con el uso del suelo, aunque el número de grupos funcionales en las áreas en restauración y en el bosque de niebla fue ligeramente superior. En general, nuestros resultados sugieren que después de siete años, la restauración activa proporciona heterogeneidad de hábitat y vegetación leñosa capaces de mantener especies de anfibios y grupos funcionales similares a los que habitan en el bosque de niebla. Los fragmentos de bosque adyacentes a las áreas de restauración parecen facilitar la recolonización de la fauna, lo cual resalta la importancia de la conservación de los ecosistemas de referencia para lograr el éxito de la restauración.</span>

Se han escrito libros con títulos
similares: <i>The distribution and abundance of animals</i> (Andrewartha y Birch,1964),

otros que en su contenido abordan este tema.
<br /><br />
De hecho, una definición de ecología
es el estudio de los factores que determinan la distribución y abundancia de las especies.
Es decir, la ecología tiene que ver con el número de individuos o especies en una
población o de una comunidad,respectivamente. Estos 3 parámetros, la abundancia,
ocupación(distribución) y riqueza, frecuentemente son el tema centralde muchos trabajos
de tesis, investigaciones científicas y conaplicación directa en la conservación
y manejo de la vida sil-vestre. Además, se han escrito libros dedicados exclusivamentea
la estimación de estos parámetros, por citar algunos: <i>Dis-tance sampling: estimating
abundance of biological populations</i>(Buckland, Anderson, Burnham y Laake, 1993),
Occupancyestimation and modeling: inferring patterns and dynamics of species occurrence
(MacKenzie et al., 2006) y <i>EstimateS: sta-tistical estimation of species richness
and shared species from samples</i> (Colwell, 2013).

<br /><b>Abstract</b></span>
<br /><br />
Bats represent around one-fourth of the world’s mammals and their taxonomy is still controversial. Molossids are one of the most diverse bat families with a wide knowledge gap. In this study, we report the first complete mitochondrial genomes of three molossid bats: the European free-tailed bat <i>Tadarida teniotis</i>, the La Touche’s free-tailed bat <i>Tadarida latouchei</i>, and the Wrinkle-lipped free-tailed bat <i>Chaerephon plicatus</i>.

<span id="exas"> ... View full abstract</span></a>
<div id="abstr" style="display: none;">
<span>
The mitogenomes are 16,869 and 16,784 bp long for <i>T. teniotis</i> and <i>T. latouchei</i>, respectively, while in <i>C. plicatus</i> it is at least 16,216 bp although the control region was not fully recovered due to its higher divergence from <i>T. teniotis</i>. The genomes show conserved synteny with other mammalian mitogenomes, containing 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 control region (d-loop). All protein-coding genes start with the ATG start codon, except for ND2, ND3, and ND5 which begin with ATA or ATT. Eleven protein-coding genes terminated in a canonical stop codon, TAA or TAG, two contain incomplete stop codons, T or TA. Cytochrome b terminates in the mitochondria-specific stop codon AGA. These mitogenomes provide a valuable resource for future studies of Molossidae and other bat and mammal species.

<br /><b>Abstract</b></span>
<br /><br />
Species delimitation is a major topic in systematics. Species delimitation methods based on molecular
data have become more common since this approach provides insights about species identification via
levels of gene flow, the degree of hybridization and phylogenetic relationships. Also, combining multilocus
mitochondrial and nuclear DNA leads to more reliable conclusions about species limits.

<span>
Coalescentbased
species delimitation methods explicitly reveal separately evolving lineages using probabilistic
approaches and testing the delimitation hypotheses for several species. Within a multispecies, multilocus,
coalescent framework, we were able to clarify taxonomic uncertainties within S. cyanostictus, an
endangered lizard that inhabits a narrow strip of the Chihuahuan Desert in Mexico. We included, for
the first time in a phylogenetic analysis, lizards from the three populations of <i>S. cyanostictus</i> recognized
so far (East Coahuila, West Coahuila and Nuevo León). Phylogenetic analysis corroborates the hypothesis
of two separately evolving lineages, i.e. the East and West Coahuila populations, as proposed in a previous
study. We also found a distant phylogenetic relationship between the lizards from Nuevo León and those
of East and West Coahuila. Finally, based on the species delimitation results, we propose and describe a
new species of Sceloporus: <i>S. gadsdeni</i> sp. nov.

<br />
The Horned Guan (<i>Oreophasis derbianus</i>) is a cracid restricted to cloud
forests in the Sierra Madre of Chiapas in Mexico and the westerncentral
Mountains in Guatemala. It is an endangered species and
urgent conservation measures are required, such as non-invasive
monitoring techniques. Here, we study individual features in the boom
calls of Horned Guans.

Boom calls are acoustic signals used by males
during courtship and territorial displays. This call is made of seven
notes, divided into two parts: an introductory section characterized
by low-amplitude notes and a body section characterized by highamplitude
notes. We recorded 10 males during the breeding seasons
of 2010 and 2011 in two captive populations and measured 22 acoustic
variables of the calls. We used a combination of statistical analyses to
test individuality in Horned Guan vocalizations. Our results showed
that time-related variables – but not frequency-related traits – varied
between individuals, and that individual calls showed no variation
between years. Our results suggest that Horned Guan individuals
can be distinguished using fine structural characteristics of their calls
and that calls remain stable across years. We argue that such vocal
signature could be used to track wild populations as a non-invasive
technique in order to improve census data in the short and long term.

<br />
Dramatic increases in human populations and per capita consumption, climate change, overexploitation of
marine and freshwater resources, and deforestation have caused a litany of negative consequences for biodiversity.
Such doom-and-gloom scenarios are widely known, frequently cited and frankly depressing. Although accurate assessments
of threats have clear value for intervention planning, we believe there is also a need to reflect on successes.
Such reflection provides balance to negative scenarios and may shift attention towards constructive, positive action. </span>

Here we use a systematic evaluation of 90 success stories provided by conservation scientists and practitioners
to explore the characteristics of the projects perceived as being associated with success. Success was deemed to have
occurred for 19.4% of the projects simply because an event had occurred (e.g. a law was passed) and for 36.1% of projects
quantitative data indicated success (e.g. censuses demonstrated population increase). However, for most projects
(63.9%) there was no evaluation and success was defined by the subjective opinion of the respondent. Conservation
community members viewed successful projects most often as those being long-term (88%), small in spatial
scale (52%), with a relatively low budget (68%), and involving a protectionist approach alone or in combination with
another approach. These results highlight the subjectivity of definitions of success in conservation but also the
characteristics of conservation efforts that the conservation community perceives as indicative of success.

Los murciélagos hematófagos se distribuyen en Latinoamérica, desde México hasta el norte de Argentina (Greenhall et al. 1983, Greenhall et al. 1984, Greenhall & Schutt 1996). Estos murciélagos contribuyen a regular las poblaciones de fauna silvestre de las que se alimentan (González Christen 2003). Las especies Diphylla ecaudata y Diaemus youngi también contribuyen en el mantenimiento de la salud de las poblaciones ya que solo atacan individuos débiles o enfermos (Horváth 2010). De las tres especies (<i>D. ecaudata</i>, <i>D. youngi</i> y <i>Desmodus rotundus</i>) que se distribuyen en México, D. rotundus es la más común y la que se alimenta de diversas especies de mamíferos silvestres, así como de ungulados domésticos (Johnson et al. 2014). También se considera como una de las principales especies hospederas y transmisoras de la rabia (Correa-Scheffer et al. 2014).</span><br />

<b>Resumen</b>
<br /><br />
El capítulo trata sobre el papel de las Áreas Protegidas, sobre todo Reservas de la Biosfera,
desde que fueron establecidas las primeras de Latinoamérica en México: "Mapimí",
representando el Desierto Chihuahuense, y "La Michilía" representando los bosques templados
secos de la Sierra Madre Occidental, como sitios idelaes para llevar a cabo investigaciones sobre las
poblaciones faunísticas, comunidades y ecosistemas que generen información básica para el
mejor entendimiento, uso y conservación de los recursos naturales. Como ejemplos, se tratan los estudios
generados sobre los venados en México, que son considerados como el recurso cinegético más
importante en el país, y muy utilizado por las comunidades indígenas como un recurso alimentario
importante, cuyos resultados han servido para diseñar planes de manejo a través de las Unidades de
Conservación y Manejo (UMA).
<br /><br />
Otro ejemplo son los estudios ecológicos a largo plazo, sobre todo incluyendo las comunidades de
roedores, lagomorfos y carnívoros, dentro del Programa LTER (Long Term Ecological Research), que se
inicia en México en 1994 instalando los sitios de monitoreo en la Reserva de la Biósfera
"Mapimí", Durango, y se formaliza como Mex-LTER en abril de 2002 junto con otros ocho sitios.

<br /><b>Abstract</b>
<br /><br />
Several recent studies have tried to unravel the complex evolutionary history of Neotropical cervids.
However, the two Mesoamerican brocket deer <i>Mazama pandora</i> and <i>M. temama</i> have not been included
in these studies and their relationship to other Neotropical cervids remains unclear. Here, we present
analyses that included concatenated sequences from the mitochondrial genes <i>ND2</i>, <i>Cytb</i>, and tRNA-Pro-Control region.<br /><br />
Our results suggest that both Mesoamerican brocket deer fall within the “red” clade,
more closely related to genus <i>Odocoileus</i> and red brocket deer species, such as South American <i>Mazama
americana</i>, <i>M. bororo</i>, <i>M. nana</i>, and <i>M. rufina</i>.<br /><br />
We estimated that <i>M. temama</i> diverged from other red brocket deer ca. two MYA. Two hypothesis emerge regarding the relationship of the Yucatan brocket deer <i>M. pandora</i> with respect to the other Neotropical deer.
<ul>
<li>
<span style="color:#333">The first one, based on analyses of concatenated sequences from all three genes, implies an early split from a larger clade that includes <i>Odocoileus</i> and other red Mazama species, with an estimated divergence time dating back to 2.7 MYA. This would suggest isolation on the Yucatan peninsula, limiting the crossing of this species into South America.</span>
</li>
<li>
<span style="color:#333">The second one, based only on <i>Cytb</i>, places <i>M. pandora</i> more closely related to <i>Odocoileus</i> and with an estimated divergence time of ca. 1.9 MYA. This would suggest that the humid tropical forests of Mexico and Central America could have been the most likely place of origin of members of the red brocket deer clade.</span>
</li>
</ul>
Deer colonization into South America occurred after the complete formation of the Panamanian land bridge in the late Pliocene, more than one ancestor of the gray brocket deer clade crossed into South America, as well as a red brocket deer ancestor and <i>Odocoileus</i> dispersed southward. A posterior event probably occurred when divergent ancestors of <i>M. temama</i> and <i>M. pandora</i> respectively moved northward after the split with South American red brocket deer.<br /><br />
Our results add to the growing body of evidence calling for an extensive taxonomic revision of this group, and we concur with previous recommendations that
the generic taxonomic designation of <i>Mazama</i> should be applied not only to the red brocket deer but also
to all of the species currently recognized under the genus <i>Odocoileus</i>.

<br /><b>Abstract</b></span>
<br />
Relative abundance of the gray fox Urocyon cinereoargenteus (Carnívora: Canidae) in Veracruz
central area, Mexico. The gray fox, Urocyon cinereoargenteus, is a medium-size canid widely distributed in
México. Most studies on this species focus on habitat use, home range, diet, intraguild competence, and lanscape
distribution between urban and rural sites. In central Veracruz, gray foxes are present in fragments of cloud forest
and in shaded coffee plantations; nevertheless, its abundance has not yet been compared among other vegetation
types found in the area, such as sugarcane plantations. In this study we described gray foxes abundance variations
using 500 m transects, among sugarcane plantations, shaded coffee plantations, and cloud forest fragments
throughout eight months, by scat counting in three sites of each cover type. We reported the relative abundance
index for each cover type and each month, and evaluated its relationship with four landscape features:
<ol type="a">
<li> shade percent,</li>
<li>trail density,</li>
<li>human population density, and</li>
<li>habitat juxtaposition, in influence areas of 450 ha around sampling sites.</li>
</ol>
Abundance comparison among cover types showed lower abundances in cloud forest
fragments and higher abundances in coffee and sugarcane plantations. No significant differences were found
throughout months (p = 0.476). We proposed that higher abundances in plantations may be related to the presence
of rodent plagues and fruit trees which offer food resources to gray foxes. The evaluation of landscape
features showed that only medium-impact trail density and human population density were positively correlated
with gray fox abundance; fact that demonstrates that this canid can coexist with humans in rural sites. We highlight
the gray fox capacity to take advantage of heterogeneous landscapes.<br />

<b>Abstract</b><br />
This paper classifies the vegetation types that comprise the habitat of the white-tailed deer Odocoileus virginianus at a location within the Tehuacan-Cuicatlan Biosphere Reserve (TCBR) in Mexico.<br /><br />
The vegetation was sampled, identified, and mapped at 308 points distributed along 28 transects (each of 500 m in length). To determine the effect of the classified and mapped vegetation types on the white-tailed deer, we estimated population density using the PELLET procedure based on the pellet-group count method.<br /><br />
The principal vegetation types at the study site are tropical dry forest (TDF, 63% of the area) dominated by tetecho (Neobuxbaumia tetezo), uña de gato (Mimosa spp.) and mulato (Bursera spp.), and crassicaule scrub dominated by mantecoso (Parkinsonia praecox).<br /><br />
The TDF can be sub-classified into four spatially different clusters (vegetation types) depending on the dominance of these species. The white-tailed deer population density varied significantly depending on vegetation type.
Our results contribute to the ecological knowledge of the white-tailed deer in tropical habitats and are of value for the implementation of effective conservation and management.<br /><br />

In Mexico, the state of Oaxaca is the second with higher mammalian richness. However, habitat loss and poaching have resulted in the decline and extinction of several species of flora and fauna. The present study focused on identifying the species richness and the relative abundance of medium and large mammals in the community of San Gabriel Casa Blanca, in the Biosphere Reserve Tehuacán-Cuicatlán. The work is important for the management and conservation of wildlife.</span>

<b>Abstract</b>
<br />
To construct informed conservation plans, researchers must go beyond understanding readily apparent
threats such as habitat loss and bush-meat hunting. They must predict subtle and cascading effects of
anthropogenic environmental modifications. This study considered a potential cascading effect of deforestation
on the howler monkeys (<i>Alouatta pigra)</i> of Balancán, Mexico. Deforestation intensifies flooding. Thus, we
predicted that increased flooding of the Usumacinta River, which creates large bodies of water that slowly
evaporate, would produce increased lead content in the soils and plants, resulting in
lead exposure in the howler monkeys. The average lead levels were 18.18 ± 6.76 ppm in the soils and 5.85 ±
4.37 ppm in the plants. However, the average lead content of the hair of 13 captured howler monkeys was 24.12 ±
5.84 ppm. The lead levels in the animals were correlated with 2 of 15 blood traits (lactate dehydrogenase and
total bilirubin) previously documented to be associated with exposure to lead. Our research illustrates the
urgent need to set reference values indicating when adverse impacts of high environmental lead levels occur,
whether anthropogenic or natural, and the need to evaluate possible cascading effects of deforestation on
primates.

<b>Abstract</b>
<br />
The measurement of sexual steroids over time allows
evaluating the changes in reproductive function of individuals. We
evaluate the profiles of fecal testosterone (T<sub>f</sub>) and fecal estradiol (E<sub>2f</sub>)
of three males and four females of Oreophasis derbianus (Aves: Cracidae)
in a breeding program. Sex steroids faecal samples were quantified
by a chemoluminiscence immunoassay. There are not significant
differences in the T<sub>f</sub> concentrations between males (P = 0.894) and
along the sampling time (P = 0.305), but there was a hormone pattern
corresponding with monogamous mating system, even when the
polygyny has been reported in this bird. One of the individuals had
higher concentrations E<sub>2f</sub> (34.09 ± 1 .08 ng/g) than the other two (6.83
± 1 .38 and 7.98 ± 2.13 ng/g), suggesting a greater reproductive age, as
has been previously reported that this hormone increases with senescence.
The females did no show significant differences between them
(P = 0.473) and along sampling time (P = 0.668). The evaluation of
the concentrations of both steroids in the same individual and their
ratio allowed defining that the hormonal activity corresponds to the
traditionally assigned to each sex, where males show Tf concentrations
larger than females and the opposite in the case of E<sub>2f</sub>. The E<sub>2f</sub>/T<sub>f</sub> ratio
is therefore greater in females. In captivity, estimate the gonadal activity
to determine the success or reproductive failure, assess sexual maturity
and fertility of wild animals, allow determining if an individual
or group has the ability to reproduce and become part of a breeding
program.

<b>Abstract</b>
<br />
Many regions around the world concentrate a large number of highly endangered species that have very restricted distributions. The mountainous region of central Veracruz, Mexico, is considered a priority area for amphibian conservation because of its high level of endemism and the number of threatened species. The original tropical montane cloud forest in the region has been dramatically reduced and fragmented and is now mainly confined to ravines and hillsides. We evaluated the current situation of amphibian diversity in the cloud forest fragments of this region by analyzing species richness and abundance, comparing assemblage structure and species composition, examining the distribution and abundance of threatened species, and identifying the local and landscape variables associated with the observed amphibian diversity. From June to October 2012 we sampled ten forest fragments, investing 944 person-hours of sampling effort. A total of 895 amphibians belonging to 16 species were recorded. Notable differences in species richness, abundance, and assemblage structure between forest fragments were observed. Species composition between pairs of fragments differed by an average of 53%, with the majority (58%) resulting from species replacement and the rest (42%) explained by differences in species richness. Half of the species detected are under threat of extinction according to the International Union for Conservation of Nature, and although their distribution and abundance varied markedly, there were also ubiquitous and abundant species, along with rare species of restricted distribution. The evident heterogeneity of the ten study sites indicates that to conserve amphibians in a mountainous region such as this one it is necessary to protect groups of fragments which represent the variability of the system. Both individually and together cloud forest fragments are very important to conservation because each remnant is inhabited by several threatened species, some of them at imminent risk of extinction.

<span><b>Abstract</b><br />
The current distribution of the endemic Perote
ground squirrel (Xerospermophilus perotensis) and its
future potential response to climate change have not been
addressed. Thus, in this work, we focus on both aspects of
this species by means of ecological niche modeling, using
different general circulation models and Intergovernmental
Panel on Climate Change emission scenarios.<br /> Because
the species’ life history includes a hibernation period,
we performed two different sets of analysis: one considering
the whole annual cycle and another considering
only the species’ active season. According to our results,
the current potential distribution of X. perotensis extends
further out of the Oriental Basin, to which the species is
endemic. Future projections vary among different climatic
scenarios and data sets used in the modeling process,
but virtually all of them project a substantial encroachment
of the species’ potential distribution area by 2050.
Our models suggest that, compared with species that are
active throughout the year, X. perotensis, being a seasonal
species, could be affected by climate change, increasing
the risk of extinction. This may pose a serious threat to
the Perote ground squirrel’s persistence throughout the
following decades.</span>

La nutria neotropical, <i>Lontra longicaudis annectens</i>, o “perro de agua” es un depredador tope de los ecosistemas acuáticos tropicales y es considerada como una especie indicadora del estado del hábitat. A pesar de su importancia ecológica, existe un vacío de información sobre el estado de sus poblaciones en México y sobre las prioridades para su conservación en las diferentes cuencas hidrológicas y en las áreas naturales protegidas en que se encuentra.<br />
La nutria neotropical está catalogada como “amenazada” en la Norma Oficial Mexicana y como en “peligro de extinción” por la Convención sobre el Comercio Internacional de Especies Amenazadas de Flora y Fauna Silvestres (CITES).<br />
La Reunión Nacional para la Conservación de la Nutria Neotropical tiene como objetivos:
<br />
<ul>
<li>
<span style="color: cyan;"> contribuir al conocimiento del estado de conservación de las poblaciones de la nutria neot<span style="font-size: small;">ropical</span></span>
</li>
</ul>
<ul>
<li>
<span style="color: cyan;"> proponer alternativas de manejo del hábitat de la especie para reducir las amenazas a las que se enfrentan</span>
</li>

<span><b>Abstract</b><br />Cracids are among the most vulnerable groups of Neotropical birds. Almost half of the species of this family
are included in a conservation risk category. Twelve taxa occur in Mexico, six of which are considered
at risk at national level and two are globally endangered. Therefore, it is imperative that high quality,
comprehensive, and high-resolution spatial data on the occurrence of these taxa are made available as a
valuable tool in the process of defining appropriate management strategies for conservation at a local and
global level. We constructed the CracidMex1 database by collating global records of all cracid taxa that
occur in Mexico from available electronic databases, museum specimens, publications, “grey literature”,
and unpublished records. We generated a database with 23,896 clean, validated, and standardized geographic
records.<br /><br /> Database quality control was an iterative process that commenced with the consolidation
and elimination of duplicate records, followed by the geo-referencing of records when necessary, and
their taxonomic and geographic validation using GIS tools and expert knowledge. We followed the georeferencing
protocol proposed by the Mexican National Commission for the Use and Conservation of
Biodiversity. We could not estimate the geographic coordinates of 981 records due to inconsistencies or
lack of sufficient information in the description of the locality.
Given that current records for most of the taxa have some degree of distributional bias, with redundancies
at different spatial scales, the CracidMex1 database has allowed us to detect areas where more sampling
effort is required to have a better representation of the global spatial occurrence of these cracids. We
also found that particular attention needs to be given to taxa identification in those areas where congeners
or conspecifics co-occur in order to avoid taxonomic uncertainty.<br /><br /> The construction of the CracidMex1
database represents the first comprehensive research effort to compile current, available global geographic
records for a group of cracids. The database can now be improved by continuous revision and addition of
new records. The CracidMex1 database will provide high quality input data that could be used to generate
species distribution models, to assess temporal changes in species distributions, to identify priority areas
for research and conservation, and in the definition of management strategies for this bird group. This
compilation exercise could be replicated for other cracid groups or regions to attain a better knowledge of
the global occurrences of the species in this vulnerable bird family.</span>
