Marked decline in forest-dependent small mammals following habitat loss and fragmentation in an Amazonian deforestation frontier [PDF]
, 2020 Agricultural frontier expansion into the Amazon over the last four decades has created million hectares of fragmented forests. While many species undergo local extinctions within remaining forest patches, this may be compensated by native species from ...

Generalized isolation forest for anomaly detection [PDF]
Pattern Recognition Letters, 2021 Abstract This letter introduces a generalization of Isolation Forest (IF) based on the existing Extended IF (EIF). EIF has shown some interest compared to IF being for instance more robust to some artefacts. However, some information can be lost when computing the EIF trees since the sampled threshold might lead to empty branches.

Terrestrial molluscs of Pemba Island, Zanzibar, Tanzania, and its status as an "oceanic" island [PDF]
, 2010 Pemba is thought to have had a longer and/or stronger history of isolation than its better-known counterpart, Unguja. The extent to which the biota support this hypothesis of greater oceanicity have been debated.

Forest patch isolation drives local extinctions of Amazonian orchid bees in a 26 years old archipelago [PDF]
, 2017 Major hydroelectric dams are among key emergent agents of habitat loss and fragmentation in lowland tropical forests. Orchid bees (Apidae, Euglossini) are one of the most important groups of specialized pollinators of flowering plants in Neotropical ...
