Species abundance and asymmetric interaction strength in ecological networks [PDF]
Oikos, 2007 The strength of interactions among species in a network tends to be highly asymmetric. We evaluate the hypothesis that this asymmetry results from the distribution of abundance among species, so that species interactions occur randomly among individuals. We used a database on mutualistic and antagonistic bipartite quantitative interaction networks.

Sponge distribution and the presence of photosymbionts in Moorea, French Polynesia [PDF]
PeerJ, 2016 Photosymbionts play an important role in the ecology and evolution of diverse host species within the marine environment. Although sponge-photosymbiont interactions have been well described from geographically disparate sites worldwide, our understanding

Heat Stress Altered the Vaginal Microbiome and Metabolome in Rabbits
Frontiers in Microbiology, 2022 Heat stress can have an impact on parental gamete maturation and reproduction functions. According to current research, the microbial composition of the vaginal cavity is species specific. Pregnancy, menstruation, and genital diseases have been linked to

Trophic ecology of an abundant predator and its relationship with fisheries [PDF]
Marine Ecology Progress Series, 2013 Trophic studies are key components in animal ecology and fisheries research. Although stomach samples are often obtained from fisheries, diet studies that consider the influence of fisheries on dietary results are still lacking. Here, the diet of the draughtboard shark Cephaloscyllium laticeps, an abundant mesopredator in Tasmanian waters, was ...

Tiger abundance and ecology in Jigme Dorji National Park, Bhutan
Global Ecology and Conservation, 2023 Conservation of large carnivores, especially, wild tigers (Panthera tigris) require an accurate population estimate and knowledge of their ecology. Camera traps have been widely used to estimate the population abundance of animals with unique natural ...

Covariations in ecological scaling laws fostered by community dynamics [PDF]
Proceedings of the National Academy of Sciences, 114(40),
10672-10677, 2017 Scaling laws in ecology, intended both as functional relationships among ecologically-relevant quantities and the probability distributions that characterize their occurrence, have long attracted the interest of empiricists and theoreticians. Empirical evidence exists of power laws associated with the number of species inhabiting an ecosystem, their ...
