Long-term transportation of juvenile pacamãs Lophiosilurus alexandri at different densities
Acta Scientiarum: Technology, 2017 This study aimed to evaluate the effects of long-term transportation of juvenile pacamã at different densities. The transportation lasted 11 hours at densities of 40, 55, and 70 juveniles (2.1±0.6 g weight) per bag containing 8 L of water.

Variation in Bird Gut Microbiota Across Dietary Guilds and Migratory Strategies. [PDF]
Ecol EvolThis study analyzed the gut microbiota of birds from different ecological types in Nanning, Guangxi, and found that different dietary habits (omnivory, carnivory, and herbivory) and migratory strategies (migratory and resident) significantly altered the gut microbiota of birds, but migration did not increase the inter‐individual variability of gut ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties
Journal of Animal Ecology, EarlyView.Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Journal of Animal Ecology, EarlyView.This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Effect of dietary plant proteins on flesh quality traits of rainbow trout (Oncorhynchus mykiss)
Italian Journal of Animal Science, 2011 The reduction of fish meal in aquaculture feeds is a priority goal for the further expansion and sustainability of the farmed fish production. Some encouraging results, also in carnivorous species as salmonids, are obtained by partial and even total ...

Integrative Zoology, EarlyView.We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change
Integrative Zoology, EarlyView.Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

The Australian Hydromyine Rodents—Their Interspecific Diversity and Reproductive Biology: A Review
Integrative Zoology, EarlyView.There are two major groups, the Rattus species and the Hydromyini, in Australia. Clearly, the hydromyine rodents, unlike the Rattus genus, exhibit a diverse array of reproductive biological traits in both males and females, the full evolutionary significance of which has yet to be ascertained.
