Between birch and berries: seasonal dietary niche partitioning among sympatric alpine herbivorous birds

Oikos, Volume 2026, Issue 8, August 2026.
Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...

Detecting social‐ecological fit in Natura 2000 governance and management: Evidence from LIFE projects focused on forest protected habitat types

People and Nature, Volume 8, Issue 8, Page 2521-2540, August 2026.
Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

Water and Gas Exchange Responses of Five Related Blueberry Species (Ericaceae spp.) to the Dry Season in the High‐Andean Forest of the Colombian Eastern Cordillera

Plant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Vaccinium, Cavendishia, and Macleania are typical genera of blueberries from the Ericaceae belt, a narrow ecosystem that connects the high Andean forest and páramo, where fragmentation makes the species more vulnerable to climate change. To answer the question of whether five related blueberry species could physiologically behave similarly in ...

Global Carbon Investment in Terrestrial Biological Nitrogen Fixation

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Biological nitrogen (N) fixation (BNF) provides the N needed to produce proteins and other biological building blocks, helping feed humanity and mitigate climate change. Due to its high energetic cost compared to other forms of N acquisition, biotic investment in BNF indicates N limitation. Globally gridded BNF flux data provide an opportunity

More than just a margin: Local and landscape‐scale factors regulating the effects of riparian forest buffers on stream‐riparian ecosystems in urban and agricultural landscapes

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Riparian forest buffers support biodiversity, ecosystem functioning and food webs in human‐modified landscapes, and dampen land‐use and climate stressors (sediments, nutrients, thermal maxima), motivating their wider use in management. These outcomes were regulated by the presence or size of mostly small, mature buffers and sometimes by proximity among

Nest boxes as microhabitats supporting diverse arthropod communities

Ecological Entomology, Volume 51, Issue 4, Page 832-837, August 2026.
Diverse Micro‐Habitats: Nest boxes supported 3634 arthropods from 82 families, highlighting their significant conservation value as artificial micro‐habitats for diverse invertebrate communities beyond their primary use for birds. Occupancy Boosts Diversity: Occupied nests exhibited significantly higher arthropod richness, abundance and Shannon ...
