Ageing in Honeybees: Telomere Length Is Driven by Climate and Resource Availability Rather Than Urbanisation or Pollution. [PDF]
Glob Chang BiolWe analysed telomere length in 981 honeybee foragers sampled across 57 sites spanning a ~1000 km gradient of urbanisation, environmental pollution, climate and floral resources in central Argentina. Telomere length declined with increasing mean annual temperature and floral abundance, while showing no association with urbanisation or chemical ...

Tropical Land-Use Change Disrupts Zeta-Diversity Across Taxa. [PDF]
Glob Chang BiolWe studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.

Effects of canopy connectivity on the arboreal ant community in coffee shade trees
Biotropica, Volume 55, Issue 6, Page 1106-1113, November 2023., 2023 We manipulated connectivity between the crowns of large shade trees and found more species and increased compositional similarity in connected crowns. Differences in connectivity in the upper canopy may be important in structuring differences in ant communities in shaded agricultural systems and unmanaged forests.

Insights from experiences comanaging woody invasive alien plants in Argentina
Ecological Solutions and Evidence, Volume 4, Issue 4, October–December 2023., 2023 The complexities of invasive alien species (IAS) management call for a close collaboration among stakeholders to comanage effective solutions. Based on a SWOT analysis, we identified personal motivations as the main force that helps to overcome barriers to to IAS comanagement in Argentina. We recommend the development of spaces to share experiences and

A low‐cost IoT network to monitor microclimate variables in ecosystems
Methods in Ecology and Evolution, Volume 14, Issue 4, Page 1025-1034, April 2023., 2023 Abstract Microclimatic and macroclimatic data differ, and microclimatic data are most useful at short time intervals (30‐min scales rather than daily/monthly scales). We developed an end‐to‐end system to acquire such data at a high temporal resolution, transfer them to a server through an Internet of Things network using low‐cost technologies, and make
