Passive transponder implantation in Theraphosidae: A tool for traceability and conservation

open access: yesInsect Conservation and Diversity, EarlyView.
PIT TAG microchip implantation was successfully performed in multiple tarantula species, showing high tolerance, rapid recovery from anaesthesia and no mortality associated with the procedure. Microchips remained stable and detectable after successive ecdysis events, with no negative effects on feeding behaviour, development, courtship, mating success ...

Elevation shapes alpine snow algal blooms and their influence on albedo reduction

open access: yesNew Phytologist, EarlyView.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Significance of Temperature-Rearing Conditions for Shaping the Responses of the Aphid Parasitoid, Aphidius platensis, Under Thermal Stress

open access: yesAgriculture
A key aspect of climate change’s impact on organisms lies in understanding their ability to adapt to shifting and stressful environmental conditions. Insects, such as parasitoid wasps, are particularly vulnerable due to limited heat tolerance.

Which, when, and where traits matter: functional trait‐mediated species associations shift with microenvironmental and climatic variation

open access: yesNew Phytologist, EarlyView.
Community‐level fitted relationship between spatial association Lij and trait dissimilarity (tDij) at the fine spatial scale (r = 40 mm; where r represents the radius around individuals of the focal species). Summary Predicting coexistence in species‐rich plant communities requires understanding the role of functional traits in species interactions and

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 ...

The role of biological control in the sustainability of the Cuban agri-food system

open access: yesElementa: Science of the Anthropocene, 2018
We analyze the role biological control plays in the Cuban agri-food system and discuss an experience at the country level that demonstrates that the pest problem can be handled through an ecological and sustainable approach.
