A network analysis of failure pathways for fish and fish habitat offsets

open access: yesConservation Science and Practice, EarlyView.
Biodiversity offsets are widely used to compensate for environmental impacts, yet failures often arise from interacting factors rather than isolated issues. By analyzing co‐occurrence patterns across 48 fish and fish habitat case studies, we identify five recurring failure syndromes: foundational, implementation uncertainty, biological, hydrological ...

ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Spatially resolved mapping of histones reveals selective neuronal response in Rett syndrome

open access: yesThe FEBS Journal, EarlyView.
Loss of Mecp2 function is associated with Rett syndrome (RTT). MeCP2 regulates chromatin, yet its influence on histone composition and dynamics is unclear. Combining MALDI‐MSI with LCM–LC–MS/MS, we mapped histone proteoforms across the dentate gyrus, cornu ammonis, and cerebellum in two mouse models of RTT.
