Reproductive Biology, Mating System, and Extended Natal Association in the Echolocating Dalou Mountains Tree Mouse (Typhlomys daloushanensis): Insights Into Sensory Adaptation and Life‐History Strategy

Integrative Zoology, EarlyView.
Typhlomys daloushanensis, a poorly known and unique echolocating rodent. Using a captive breeding colony, we quantify key reproductive parameters, including gestation length, litter size, interbirth interval, and development to maturity, and evaluate these in relation to mating system structure.

Some Tuco‐Tucos Hide More Than Others: An Integrative Approach Reveals Cryptic Diversity in Ctenomys (Rodentia: Ctenomyidae) From Central Argentina

Integrative Zoology, EarlyView.
Here, we adopt an integrative framework (molecular phylogenetics and geometric morphometrics) to reassess patterns of diversity and differentiation across this region. We analyzed cytochrome b sequences and quantified cranial shape variation. Our analyses indicate the presence of three species groups (mendocinus, talarum, and tucumanus) and two ...

Genomic Diversity of the Endangered Guinan Toad‐Headed Lizard and Its Conservation Implications

Integrative Zoology, EarlyView.
We produced HiFi long reads and assembled a high‐quality genome for the Guinan toad‐headed lizard—Phrynocephalus guinanensis—and present a comprehensive conservation genomics assessment. Our findings clearly show population structure, a reduced genetic diversity pattern, and a strong bottleneck in demographic history, reaffirming the endangered status ...

Urban Environments Impact Parasite Diversity and an Antipredator Response in an Amphibian Model

Integrative Zoology, EarlyView.
Urbanization reshapes parasite–host interactions in the amphibian Pelophylax perezi, increasing blood parasite diversity and Lankesterella loads under higher anthropogenic pressure. Urban frogs also show longer flight initiation distances and tibiofibulae, indicating altered antipredator strategies.

Seismic Signaling Associated With Breeding‐Season Spatial Behavior in the Subterranean Plateau Zokor

Integrative Zoology, EarlyView.
Eospalax baileyi shows seismic signals associated with nasal‐pad striking and corpuscle‐like structures potentially relevant to mechanosensation. Artificial seismic disturbance was based on the temporal structure of breeding‐season recordings, and pregnancy prevalence was 3/10 in the interference plot and 8/10 in the control plot.

Handling mean–variance scaling in intraspecific trait variability and implications for trait–environment analyses

Methods in Ecology and Evolution, EarlyView.
Abstract Trait‐based ecology increasingly relies on measures of intraspecific trait variability to estimate how trait diversity within species varies across species and environmental gradients. Yet variance and related metrics are often interpreted without considering their intrinsic dependence on the mean, as described by the empirical Taylor's power ...
