Anthropogenic extinctions explain most size and trophic mismatches between large mammalian primary consumers from Amazonian and African rainforests

Biotropica, Volume 57, Issue 1, January 2025.
Present‐day Amazonia has an impoverished fauna of large folivorous mammals by comparison with African rainforests, but recent fossil discoveries suggest that late‐Quaternary anthropogenic extinctions could account for most size and trophic faunal mismatches.

Genetic divergence and evidence of human‐mediated translocation of two‐fingered sloths (Choloepus hoffmanni) in Costa Rica

Evolutionary Applications, 2020
Sloths are notoriously slow and consequently have limited dispersal ability, which makes them particularly vulnerable to the effects of habitat fragmentation and degradation. Sloths in Costa Rica are considered of conservation concern due to habitat loss,

Mineral Licks: An Overlooked Model System for Species Interactions

Biotropica, Volume 57, Issue 1, January 2025.
Previous research on natural mineral licks has focused largely on characterizing the soil properties of the licks and describing the species that consume the minerals, yet mineral licks are also hubs of species interactions, where predators hunt prey, diseases are spread, and social information is transferred.
