Coinvasional disruptions to island pollinator networks

Conservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

“Humanizar”: aprendizajes sobre alteridad, salud y futuro en una experiencia de investigación compartida

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT The visit to Bogotá of a fééeneminaa (Muinane) friend, Célimo Nejedeka Jifichíu, and in particular, his work in researching and transmitting traditional health knowledge, offer the pretext to navigate the relationship between elements that at first glance seem distant from each other: indigenous imaginaries about otherness, their visions of ...

Temporal dynamics in functional fruit traits of native and invasive fleshy fruited plants in subtropical Andean forests

Functional Ecology, Volume 40, Issue 5, Page 1221-1232, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruits encompass the energetic and material flow between both interacting parties in frugivore‐mediated seed dispersal. Since fruit traits matter in frugivores' foraging decisions, the temporal dynamics of fruit traits might influence interaction outcomes.

Nematoides: bioindicadores de sustentabilidade e mudanças edafoclimáticas

Revista Brasileira de Fruticultura, 2010
Em vista do desconhecimento da importância econômica dos fitonematoides, isoladamente, em cada cultura, esses organismos têm sido frequentemente negligenciados nos agroecossistemas, somente assumindo status de patógeno quando sua população se encontra ...

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars

Functional Ecology, Volume 40, Issue 5, Page 1475-1490, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

Frost Decreases Fruit Production in a Neotropical Savanna: Implications for Frugivorous Bird Abundances

Biotropica, Volume 58, Issue 3, May 2026.
Severe frost events seem to be happening on average every 5 years, rather than 7 years, as previously reported in the southern limit of the Cerrado, a Neotropical savanna. We conducted this study in the Cerrado, where severe frost events allowed us to compare fruit production and frugivorous bird abundance before and after the disturbance.
