Manipulation of nutrient flow and digestion in defaunated sheep subjected to various dietary regimens
… 3 and 4. Compared to the faunated control, defaunation decreased total tract organic matter (OM), fiber and crude protein (CP) digestibilities, but increased flow to and digestion in the small intestine (SI) of linoleic and linolenic acids. Urea supplementation improved total tract OM …

Fishing and hunting in the Amazon floodplain : linkages among biodiversity conservation, rural livelihoods and food security
… unsustainable harvesting is causing pan-tropic defaunation. In addition to the decline of prey populations, many harvest-dependent societies in these regions are witnessing major social and environmental changes, including; rapid urbanisation, population growth, (unequal) socio-economic …

Movement of fishes in a network of streams and implications for persistence
… with colonization rates after experimental defaunation. Movement rate and abundance explained the most interspecific variation in colonization rates when compared to competing predictors (spatial distribution, body size, and family). Recovery occurred slowly and several species had not …

The Causes and Consequences of Community Disassembly in Human Modified Tropical Forest: Scarabaeine Dung Beetles as a Model System
… I outline the potential for tropical forest defaunation to negatively impact dung beetle communities, summarize the contributions of dung beetles to a range of key ecological processes, provide empirical data demonstrating how dung beetles can serve as a model system to understand terrestrial …

The influence of macrofauna on intertidal sediment stability and biogeochemical properties.
… macrofaunal biomass was removed using cryo-defaunation and the abundances of three common mudflat species Hediste diversicolor, Hydrobia ulvae and Corophium volutator manipulated to examine different aspects of macrofaunal biodiversity including species identity, density, biomass …

Assessing conservation status of remnant mammal populations in a Neotropical cloud forest
… in recent years with near complete mammalian defaunation of the park predicted as early as the mid-2020s. Analysis of camera trapping surveys indicated that large mammalian species detections were negatively associated with proximity to scientific research stations. Additionally smaller …
