Human hunters are no substitute for vanishing apex predators
Journal of Animal Ecology, EarlyView.Our study reveals that human hunters fail to replicate the collective and individual ecological functions of natural apex predators in sustaining biodiversity and promoting stable spatial patterns. These insights are vital for rethinking predator conservation and wildlife management in human‐dominated landscapes.

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 ...

Algal cover in mangroves affects distribution and predation rates by carnivorous fishes
Journal of Experimental Marine Biology and Ecology, 2012 Abstract Distribution and survival of fish are influenced by benthic habitat and complexity. While many studies have investigated the effects of algal cover on fishes in reef habitats, comparatively less is known regarding this relationship in mangrove habitats.

Goby gummies: A customizable and edible assay to quantify predation in aquatic ecosystems
Methods in Ecology and Evolution, EarlyView.Abstract Predation is a critical ecosystem process that shapes the structure and functioning of biological communities. However, due to its intermittent nature, fast pace and general unpredictability, predation is difficult to observe and quantify. Therefore, we commonly rely on indirect metrics or proxies of predation, which reflect the outcome of ...

Pea protein concentrate as a substitute for fish meal protein in sea bass diet
Italian Journal of Animal Science, 2010 Pea seeds, even if lower in protein than oilseed meals, have been shown to successfully replace moderate amounts of fish meal protein in diets for carnivorous fish species (Kaushik et al., 1993, Gouveia and Davies, 2000).
