Trapped in the web: network architectures spread coevolution and shape adaptation
Oikos, Volume 2026, Issue 7, July 2026.Adaptation is critical for biodiversity to persist under global change. Within ecological communities, species often face tradeoffs between adapting to shifting abiotic conditions and navigating the complex selective pressures imposed by interaction networks.

Global Change Biology, Volume 32, Issue 7, July 2026.Based on a global analysis of 1921 soil samples, we show that agricultural management acts as a powerful ecological filter reshaping microbial communities. Land use and inputs—pesticides and fertilizers—drive a functional shift toward opportunistic pathogens and fragmented, less connected microbial networks, potentially compromising soil ecosystem ...

Journal of Biogeography, Volume 53, Issue 7, July 2026.ABSTRACT Aim Biogeographic processes can profoundly shape the connectivity and evolutionary potential of arthropod disease vectors. We investigated how Panama's ecological and topographic transitions structure populations of the kissing bug Rhodnius pallescens, the primary vector of the Chagas disease agent Trypanosoma cruzi in the region.

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.Cell wall stress in yeast triggers transcriptional reprogramming through the CWI pathway. This study identifies Sus1, a subunit of SAGA and TREX‐2, as a key regulator in this process. Sus1 associates with stress‐responsive genes, promoting pre‐initiation complex assembly, chromatin remodeling, and RNA Pol II progression independently of H2B ...

Ecological Research, Volume 41, Issue 3, May 2026.Two helminth‐rodent networks were analyzed for two distinct areas. Network modularity, nestedness, and degree of specialization were calculated for each network. Higher network modularity than nestedness and high network specialization were observed in both networks, suggesting functional and/or taxonomic specialization between helminth species and ...
