Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

open access: yesActa Zoologica, EarlyView.

A national assessment of waterbird hunting in coastal wetlands of Suriname, South America

open access: yesConservation Science and Practice, EarlyView.
We examined waterbird harvest levels in Suriname using hunter survey data from 2006 and 2016. The analysis showed a significant decline in the average harvest per hunter over the decade, except for blue‐winged teal and migratory shorebirds. However, the sustainability of current harvest levels remains uncertain, underscoring the need for a national ...
