Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Do field margins matter more than floral resources? Arthropod activity and limited spillover of natural enemies from perennial flower strips into adjacent crops

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Both flower and grass strips supported significantly higher arthropod activity than adjacent crop fields, underlining the general ecological value of field margins regardless of floral composition. The observed group‐specific responses emphasize the need for taxa‐specific analyses within heterogeneous functional groups, rather than relying solely on ...

Effects of Time‐Since‐Fire on Ant Interactions With Nectar Resources in a Semi‐Arid Landscape

open access: yesAustral Ecology, Volume 51, Issue 7, July 2026.
ABSTRACT Semi‐arid ecosystems are shaped by frequent wildfires, making the management of landscape disturbances a major conservation challenge in this region. Ant–plant nectar interactions, driven by mutualisms, contribute to ecosystem functioning and biodiversity, with interaction networks a poorly understood aspect of ecosystem recovery from ...

Interannual MODIS NDVI Dynamics of the Grazing Areas Under Variable Precipitation in Northern Sahel

open access: yesAfrican Journal of Ecology, Volume 64, Issue 5, July 2026.
ABSTRACT The Sahel region of sub‐Saharan Africa has suffered from a severe rainfall decline since the mid‐1960s. This study aims to assess the applicability of satellite‐based observations in quantifying the dynamics of MODIS NDVI in the central‐south of the Republic of Niger.

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...
