Dress for success: climate pressures predict fur insulation and body size in natural and reintroduced populations of a threatened marsupial

Oikos, EarlyView.
Phenotypic variation in functional traits underpins responses to environmental gradients, influencing thermoregulation, energy balance, and long‐term persistence under climate extremes. Climate change is altering these gradients globally, yet in species that have already disappeared from much of their range, adaptive phenotypes may have also been lost,

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

Journal 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.

Social organization and habitat use shape the gut microbiome of a marine fish

Journal of Animal Ecology, EarlyView.
This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.

Leukocyte profiles reveal sex and age differences in immune investment in a polygynous bat

Journal of Animal Ecology, EarlyView.
Analysis of over 500 blood cell profiles, including repeat samples over four years, reveals that male bats from a long‐lived species with a polygynous mating system invest more in innate than adaptive immunity. Investment in innate immunity increases with age, as estimated by a DNA methylation clock and mark‐recapture data.

Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

Insect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

Evolution of sexually dimorphic pheromone profiles coincides with increased number of male‐specific chemosensory organs in Drosophila prolongata

Ecology and Evolution, 2019
Binary communication systems that involve sex‐specific signaling and sex‐specific signal perception play a key role in sexual selection and in the evolution of sexually dimorphic traits.

Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

Integrative Zoology, EarlyView.
This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

Integrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

Integrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Anti-hyphal properties of potential bioactive compounds for oral rinse in suppression of Candida growth

Biotechnology & Biotechnological Equipment, 2017
Most oral rinses contain active ingredients with limited antifungal activity, particularly against hyphae development. This has encouraged us to search for bioactive compounds effective against preventing morphology transition of the dimorphic Candida ...
