Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Evolution of research on global amphibian declines

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

From Colonial Natures to Entangled Ecologies: Making Due and Relational Geographies of Indigenous Resurgence in the Chaco

Antipode, Volume 58, Issue 1, January 2026.
Abstract This paper offers an alternative reading of decolonial geographies by examining how people make due in the context of colonial natures. Drawing on collaborative ethnographic research, we illustrate how everyday acts of reclaiming ancestral lands serve as practices of resistance that foment Enxet and Sanapaná resurgence in Paraguay's Chaco.
