The growth in our knowledge of the diversity herpetofauna Mexico has occurred over period approximately 445 years from work Francisco Hernández to that a broad multinational array present-day herpetologists. this huge group people established as one most significant centers herpetofaunal biodiversity world. This status is result complex orography, addition diverse habitats and environments biogeographic history Mexico. current consists 1,421 native introduced species, allocated 220 genera,...
A substantial number of changes to the composition herpetofauna Mexican state Oaxaca, including taxonomic additions and deletions, have occurred in five years since our original assessment this region. These now establish a 480 species for state. nomenclatural involving Oaxacan also are discussed. Updated patterns physiographic distribution, endemism, conservation status members examined.
The use of miniature accelerometer (ACT) data-loggers for remote and continuous recording animal movement behavior is becoming increasingly common. Until recently, size constraints limited most animal-borne ACT applications to large-bodied species. We capitalized on the ongoing miniaturization advancement these technologies associated computational techniques develop a framework long-term, low-frequency monitoring activity in small secretive terrestrial achieved this by internally implanting...
Pallid bats, Antrozous pallidus, glean prey off the ground or from vegetation. During 27 March-19 November 2004, culled parts of were collected under a night roost on Indio Mountains Research Station, Hudspeth County, Texas. Adjacent pitfall traps monitored concurrently to determine species richness and seasonal abundance potential prey. Prey representing 44 morphospecies 4 classes, 13 orders, 25 families, 34 genera recovered identified. Of identified morphospecies, 29 unrecorded previously...
Studies on habitat use have often helped explain observed variation in morphology, behavior and reproductive characteristics among populations within a single species. Here we analyze morphological ecological of individuals from the Sceloporus grammicus species complex 7 different localities (CER, El Cerezo; PAC, Pachuca; HUI, Huichapan; EZA, Emiliano Zapata; SMR, San Miguel Regla; LMJ, La Mojonera; LMZ, Manzana) state Hidalgo, one locality (Cahuacán) State Mexico. A canonical correspondence...
The species – area relationship (SAR) is a common pattern in which diversity increases with the sampled, but ecosystems are three‐dimensional (3D) and volume relationships (DVRs) may exist that vary substantially their vegetation volume. We tested whether forest volume, as 3D extension of SARs, was significant predictor taxonomic (species) structural (arrangement) five groups organisms across National Ecological Observatory Network (NEON). Vegetation four arrangement metrics within NEON...
Abstract Little is known about the ecology and behavior of Rock Rattlesnakes (Crotalus lepidus) despite species' wide geographic distribution throughout southwestern United States central Mexico. The goal this study was to quantify space use, movement patterns, habitat use by C. lepidus in Chihuahuan Desert extreme west Texas. We used radiotelemetry monitor subjects during at least one activity season from 2007 2010. Mean (±1 SE) home range size for all individuals 13.69 ± 3.06 ha, mean...
Habitat heterogeneity and local resource distribution play key roles in animal search patterns. Optimal strategies are often considered for foraging organisms, but many of the same predictions applicable to mate searching. We quantified movement space use by a pitviper test whether Native Habitats (NH) human-made Resource Hotspots (RH) facilitate alternative seasonal spatial as result critical resources, including potential mating partners, being widely dispersed NH clustered RH. Independent...
Animal-borne sensors ('bio-loggers') can record a suite of kinematic and environmental data, which elucidate animal ecophysiology improve conservation efforts. Machine learning techniques are used for interpreting the large amounts data recorded by bio-loggers, but there exists no common framework comparing different machine in this domain. To address this, we present Bio-logger Ethogram Benchmark (BEBE), collection datasets with behavioral annotations, as well modeling task evaluation...
We compared types and volume of prey in the diets two whiptail lizards (Teiidae), Aspidoscelis marmorata (a bisexual species) A. tesselata unisexual that occur syntopically a Chihuahuan Desert landscape on Indio Mountains Research Station, Hudspeth County, Texas. Because their home ranges overlap extensively, we hypothesized there would be dietary resource partitioning between species. Stomach contents 69 21 included only arthropods. used 14 orders arthropods for prey, while eight orders....
Despite its wide distribution throughout the northern Chihuahuan Desert, extraordinarily little is known about ecology or behavior of Eastern Black-tailed Rattlesnakes (Crotalus ornatus). The primary literature for was largely based on research conducted former conspecific (C. molossus); thus, revalidation C. ornatus widened void in our understanding species. aim this study to elucidate movement patterns, home range size, and habitat use by Desert far West Texas. Radiotelemetry used monitor...
We studied reproductive characteristics of two syntopic whiptail lizards, Aspidoscelis marmorata and A. tesselata, inhabiting the northern Chihuahuan Desert. Reproductive were snout–vent length at sexual maturity, size clutch, volume eggs. In marmorata, males females similar in length, but body mass was larger than females. Female tesselata snout-vent heavier female marmorata. Mean clutch 3.3 for 3.5 tesselata. Females had eggs Data suggest that both respond to environmental factors region...
Two instances of rainwater-harvesting behavior by the rock rattlesnake, Crotalus lepidus, are reported. The first observation was a male collecting water from rain and sleet on 16 February 2008, second involved another rainwater 11 July 2008. observations took place within Chihuahuan Desert landscape located in extreme southeastern Hudspeth County, Texas.
Content of the dipsadid genus Rhadinaea has changed considerably since Myers’ 1974 revision. Three species groups are recognized currently in genus. Our fieldwork Oaxaca June 2018 produced a single specimen considered to represent new taxon. This is described from converted Premontane Wet Forest municipality Santa Catarina Juquila Sierra Madre del Sur southern Oaxaca, Mexico. It most closely related Rhadinaealaureata , which it can be distinguished easily by color pattern and scutellation,...
We studied the reproductive characteristics, such as snout-vent length (SVL) at sexual maturity, clutch size, and egg volume, morphological characteristics [head (HL), head width (HW), femur (FL), tibia (TL)] in Aspidoscelis deppii A. guttata from Oaxaca, Mexico. In deppii, males were larger SVL than females, whereas guttata, females males. Males of had structures, HL, HW, FL, TL, females; contrast, similar, except which larger. Mean size was 2.3 for 4.5 guttata. Females smaller volume Both...
Cocinas and San Pancho Islands, located in the Bay of Chamela, Jalisco, México, are two few remaining island ecosystems with little ecological disturbance. We studied both islands aiming to assess their reptile richness. Because environment Chamela is seasonal, we conducted biodiversity surveys during six samplings: three dry season rainy season. found a total seven species on Islands representing first description herpetofauna. recorded four (Aspidoscelis lineattissima, Hemidactylus...
The colubrid snake genus Tantilla currently comprises 62 valid species distributed from the southern United States of America to Bolivia in west, and Uruguay northern Argentina east (Wilson & Mata-Silva 2014, 2015). Of these species, 13 are found South most recently described Southamerican is marcovani Lema, 2004. While we were working on a checklist key members clade (sensu Holm 2008, including genera Geagras Cope 1876, Scolecophis Fitzinger 1843, Baird Girard 1853, Tantillita Smith...
An adult Collared Dwarf Gecko, Sphaerodactylus glaucus, was found in Parque Nacional Lagunas de Chacahua, Cerro Hermoso, municipality of San Pedro Tututepec, Oaxaca, Mexico, at an elevation 72 m. This specimen represents a new record and the westernmost distribution species on Pacific Coast Mexico.
