Ecosphere, 2020 Inducible defense is adaptive when prey organisms cope with fluctuations of predation risk, and there exists ample variations of inducible defense both within a species and between species even in a single habitat. Daphnia, a freshwater zooplankton genus,

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‐

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.

Jurnal Ilmiah Perikanan dan Kelautan, 2009 Cadmium is one of dangerous heavy metal and it can cause water pollution. As an alternative early warning toward heavy metal in water, Daphnia magna can be used as biology indicator water pollution that caused by heavy metal.

Integrative Zoology, EarlyView.ABSTRACT The increasing frequency and intensity of heatwaves—extreme thermal events characterized by prolonged supra‐optimal temperatures—exert profound impacts on global ecosystem stability and species interactions. While the disruptive effects of thermal stress on host physiology and gut microbiota are well documented, the role of cuticular ...

Comparative study of the sensitivity of Daphnia galeata and Daphnia magna to heavy metals
Ecotoxicology and Environmental Safety, 2018 Daphnia galeata and Daphnia magna belong to the family Daphniidae. Daphnia galeata has a smaller body size and longer helmet than D. magna. Although D. galeata is widely distributed in the northern hemisphere, it is not as commonly used in aquatic ecotoxicity tests as D. magna.

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus
The FEBS Journal, EarlyView.Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not
