Diet composition and its ecological drivers are rarely investigated in coexisting closely related species.We used a molecular approach to characterize the seasonal variation in diet composition in four spiny lizard sp...
from CONACyT(MP)and the Catedras CONA-CyT program(ADP,883);the Secretaría de Medio Ambiente y Recursos Naturales for providing the collecting permits(SGPA/DGVS/15396/15 and SGPA/DGVS/007736/18).
ndividuals that inhabit broad elevational ranges may experience unique environmental challenges.Because temperature decreases with increased elevation,the ectotherms living at high elevations have to manage limited ac...
Fieldwork was conducted with permission from Secretaría de Medio Ambiente y Recursos Recursos Naturales-México(SGPA/DGVS/11338/15);We also thank JoséManuel Tivo Guzmán,Othón Cervantes Sánchez and the Comisión Nacional del Agua(CONAGUA)for providing climatic information.The first author is grateful to the Posgrado en Ciencias Biológicas,Universidad Nacional Autónoma de México for continued academic support and to the Consejo Nacional de Ciencia y Tecnología(CONACyT)for the scholarship received(779026).
Most demographic studies focus on numerical changes that occur within populations across years.However,typically studies at an interannual scale do not provide information on the particular times of the year(particul...
Parasites generally have a negative influence on the color expression of their hosts.Sexual selection theory predicts resistant high-quality individuals should show intense coloration,whereas susceptible low-quality i...
This research was approved by the Institutional Animal Care and Use Committee(Protocol#15-1431R);Collection of lizards was approved by AZ Game and Fish Department(SP721353);Funds were provided by FAPESP(Grant 15/01300-3 and 12/15754-8 to ACG);Arizona State University and Midwestern University。
Zoologists rely on mechanistic niche models of behavioral thermoregulation to understand how animals respond to climate change.These models predict that species will need to disperse to higher altitudes to persist in ...

Sceloporus lizards depend on external heat to achieve their preferred temperature(Tsel)for performing physiological processes.Evidence both in the field and laboratory indicates that pregnant females of this Genus sel...
We thank CONACyT for the scholarship granted to the first author(ALM,#16301),and projects PROMEP/103.5/04/2751 and FOMIX-CONACYT-191908.
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 and ecological charac...

Escape theory predicts that flight initiation distance (FID = distance between predator and prey when escape begins) is longer when risk is greater and shorter when escape is more costly. A few tests suggest that es...
