Altitudinal differences in alpha, beta and functional diversity of an amphibian community in a biodiversity hotspot

open access: yes, 2019
Biodiversity research along altitudinal gradients can provide us with new insights into conservation and human impacts. In this context, amphibians are a useful and important group due to their rapid response to environmental changes, severely threatened

Flexible parental care in a songbird correlates with sex‐specific responses to seasonal phenology, mating opportunity and reproductive success

open access: yesJournal of Animal Ecology, EarlyView.
This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats

open access: yesIntegrative Zoology, EarlyView.
Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...
