Hotter, faster, sicker? Warming shifts the cost of infection from individuals to populations
Journal of Animal Ecology, EarlyView.This study examines how temperature alters disease impacts across biological scales in a host–pathogen system. We found infected hosts appear healthiest at warm temperatures, yet populations suffer most. This suggests climate warming may intensify disease impacts for populations in ways traditional individual‐level virulence metrics fail to predict ...

Integrative Zoology, EarlyView.18 days of predator odor exposure altered gut microbiota, increased anxiety‐like behaviors, and elevated hypothalamic–pituitary–adrenal axis activity in Brandt's voles, with males showing behavioral habituation and females remaining sensitive. Cecal microbiota transplantation experiments confirmed that only female recipients of microbiota from predator‐

Resolving the infection process reveals striking differences in the contribution of environment, genetics and phylogeny to host-parasite interactions [PDF]
, 2011 Background Infection processes consist of a sequence of steps, each critical for the interaction between host and parasite. Studies of host-parasite interactions rarely take into account the fact that different steps might be influenced by different ...

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 ...

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans
Integrative Zoology, EarlyView.Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

, 2007 Resting egg banks of microcrustaceans have been used to reconstruct the evolutionary and ecological history of species. However, recent studies provided evidence for a discrepancy between dormant propagules in the sediment and the planktonic population ...
