Abstract Viviparity, an innovation enhancing maternal control over developing embryos, has evolved >150 times in vertebrates, and been proposed as adaptation to inhabit cold habitats. Yet, the behavioral, physiological, morphological, life history features associated with live-bearing remain unclear. Here, we capitalize on repeated origins of viviparity phrynosomatid lizards tease apart phenotypic patterns this innovation. Using data from 125 species phylogenetic approaches, find that...
The African clawed frog (Xenopus laevis) is an invasive amphibian in at least 15 countries. In Mexico, only occasional records have documented it the state of Baja California. May 2013, we discovered a population Puente el Morro Rosarito. 1-h session trapping, captured 106 individuals (adults and juveniles) small pond. We did not see eggs, tadpoles, or reproductive activity, but lengths frogs indicate that some reached sexual maturity. This discovery indicates need for conservation plans...
We studied the diet of exotic American bullfrog (Lithobates catesbeianus) in Arroyo San Carlos, located northwestern Baja California, Mexico, during spring and summer 2009. Analysis 64 stomach contents revealed 15 prey types, which red crayfish (Procambarus clarkii) terrestrial isopods (Armadillidiidae) were most significant items (according to an index their relative importance), making up 64% 31% bullfrog's diet, respectively. Diet differed between sexes, with eaten more frequently by...
Las especies exóticas invasoras representan una amenaza significativa para la biodiversidad mundial. En península de Baja California (México) estos organismos han proliferado y las medidas tomadas sido insuficientes mitigar su expansión reducir impacto ambiental. este estudio, se desarrolló un índice erradicación específico rana toro (Lithobates catesbeianus; Shaw, 1802), clasificada como 100 más dañinas a nivel global. Este índice, basado en el método Jerarquías Analíticas Saaty, utiliza 11...
We studied a remote and robust population of Actinemys pallida (Southwestern Pond Turtle) in the upper Río Santo Domingo (RSD) watershed, Sierra San Pedro Mártir, Baja California, Mexico. conducted cursory assessments 2014 2015 intensive trap-based surveys 2016 2022. captured marked 486 unique turtles total 597 times. Using closed-population models within years, we estimated abundance one 3.8-km study reach to be 511.1 (CI = 395.7–686.5) 663.8 (467.2–1011.0) 2022, equivalent instream...
El cambio climático global se considera una gran amenaza contra la biodiversidad, sin embargo, aún es incierto cómo afectará a diferentes grupos taxonómicos, pues respuesta dependerá de su historia natural y complejidad del hábitat. Así, los reptiles ambientes desérticos son particular preocupación porque deben termorregular dentro límites óptimos pesar las altas temperaturas ambientales. Este estudio enfocó en iguana desierto (Dipsosaurus dorsalis), lagartija termófila amplia distribución...
Se registra una nueva población de la tortuga poza del suroeste Emys pallida en Baja California. Este registro representa ampliación distribución 95.5 km al sur previo más sureño. También única oasis dentro ecorregión Desierto Central
Amphibians are declining globally, and the fungal pathogen Batrachochytrium dendrobatidis (Bd), which causes disease chytridiomycosis, has been culprit in many of these declines. In Mediterranean region Baja California, Mexico—a biodiversity hotspot—native amphibians also decline, Bd is present. To determine factors best predict infection prevalence intensity California anurans, we conducted sampling at three disparate sites varying elevations. We observed an overall 68%, found that species...
We found a new population of Ensatina klauberi in San Quintín volcanic field, Baja California. It represents the first coastal this species. This record extends species range ca. 71 km southwest southernmost E. Sierra Pedro Mártir and discovered outside coniferous pine-oak woodlands.
New records of the introduced gecko Hemidactylus frenatus from northwestern México are provided. One them represents first record for state Sonora.
New records of insular distribution four reptiles from northwestern México are provided: Anniella pulchra (Todos Santos Norte island), Phyllodactylus homolepidurus, (Farallón de San Ignacio Bipes biporus (Magdalena island) and Chilomeniscus stramineus (Santa Margarita island).
Ecological boundaries have been of interest to naturalists since the time Darwin and Wallace because they are transitional zones on landscape across which distinct changes occur in constitution plant animal communities. In xeric landscapes central Baja California Peninsula, fan palm (Erythea armata Washingtonia robusta) oases small (usually <1 ha) mesophilic islands structurally complex habitats. We report new records reptiles amphibians from adjacent Californian biome groves Sonoran region;...
We provide a record and field observations of California vole (Microtus californicus) based on specimen collected 5 June 2013 in riparian habitat from Arroyo San Rafael, northwestern Sierra Pedro Mártir, Baja California, México. The last known this species México was 1974. This suspected to be extirpated México; however, our recent confirms its present occurrence country.
Abstract Understanding how historical geological processes drive diversification and shape the contemporary distribution of species is fundamental to phylogeography. We take a genomic approach in order elucidate deep phylogeographical history limits chuckwallas (Sauromalus), conspicuous group lizards arid lands south-western North America. Phylogenetic population analyses double digest restriction site-associated DNA sequencing data confirm presence at least two major lineages, peninsular...
Exotic species introductions are a major threat to biodiversity.The first step their control involves identifying presence, distribution, and impacts on native habitats, especially in highly diverse regions.We update document new records of exotic freshwater fauna from the Baja California Mediterranean region.We found 157 locality 17 aquatic species; 16 genera 15 families were recorded.Five for region: Malaysian trumpet snail (Melanoides tuberculata), black bullhead catfish (Ameiurus melas),...
To protect threatened species such as the California red-legged frog (Rana draytonii) it is important to understand their natural history, including food web relationships. We report first observations of R. draytonii eating and attempting eat tarantula hawk wasps (Pepsis sp.), based on from xerophytic montane shrublands Baja California.
We collected two specimens of Reithrodontomys megalotis on Magdalena Island the Pacific Ocean side Baja California Sur. They represent first insular record species in Mexico. These records extend distribution range about 450 km south southernmost R. California. In addition, three previously unpublished localities mainland are reported.
