Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

Conservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

Host Preference and Performance of the Aphid Brevicoryne brassicae Are Not Associated With Olfactory Orientation Towards Kale and Mustard

Entomologia Experimentalis et Applicata, EarlyView.
Brevicoryne brassicae showed a preference for Brassica juncea (mustard) over Brassica oleracea var. acephala (kale) in free‐choice assays and exhibited greater population growth on B. juncea. This preference was not associated with stronger olfactory orientation toward its volatiles, as aphids preferentially oriented toward kale when both species were ...

Gender Differences in the Impact of Domestic and International Remittances on Household Food Security. Evidence From Rural Zimbabwe

Poverty &Public Policy, Volume 18, Issue 4, December 2026.
ABSTRACT Despite efforts, food security remains an elusive goal in rural Africa. Without robust safety nets, households employ alternative coping strategies, including internal and international migration to leverage remittances. Using data from a 2024 nationally representative cross‐sectional survey of 17,942 rural households conducted by the Zimbabwe

Using Artificial Intelligence to Optimize Ecological Restoration for Climate and Biodiversity

Global Change Biology, Volume 32, Issue 11, November 2026.
We present a reinforcement learning model for multi‐objective spatial restoration that jointly optimizes biodiversity, carbon sequestration, and costs. Applied to the Atlantic Forest, minor biodiversity weights yield disproportionate extinction risk reductions with small carbon loss.

Supporting pollinators, resisting policy: The role of environmental attitudes and psychological reactance among farmers

People and Nature, Volume 8, Issue 10, Page 3569-3584, October 2026.
Abstract Understanding how psychological constructs shape farmers' views on agri‐environmental policy and the role of pollinators in agriculture can help design effective and legitimate agricultural policies. While farmers are key actors in pollinator conservation, recent farmer protests indicate that their support for agri‐environmental policies such ...

Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, Volume 12, Issue 5, Page 816-831, October 2026.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...
