High Densities of Large Herbivores Rapidly Disrupt Ecosystem Integrity

Global Change Biology, Volume 32, Issue 6, June 2026.
Human‐driven increases in large herbivore populations are emerging as a widespread global change pressure on terrestrial ecosystems. Using the largest hectare‐scale herbivore density manipulation experiment conducted to date, we show that high deer densities rapidly disrupt ecosystem integrity across multiple dimensions of biodiversity and ecosystem ...

O ano internacional da biodiversidade e a biodiversidade dos polinizadores. [PDF]

, 2012
A depedência humana por agentes polinizadores é muito grande e o crescente desaparecimento das abelhas melíferas vem tornando cada vez mais relevante o estudo da criação e manejo de outras espécies de abelhas que potencialmente poderiam ser usadas como ...

RELEVAMIENTOS DE INSECTOS POTENCIALES POLINIZADORES DE TRÉBOL ROJO

Boletín de la Sociedad Zoológica del Uruguay, 2020
The reduction of pollinator populations globally generates a lot of concern about the impact it can have on the maintenance of ecosystems and cultivated species. In this work, the different insects that visited the red clover flowers, a forage legume with pollination problems in Uruguay, are reported, and their importance as pollinators is discussed.

The Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

Journal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

Differential effects of agricultural expansion on wild bee taxonomic and functional diversity

Functional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

Interaction networks and the use of floral resources by male orchid bees (Hymenoptera: Apidae: Euglossini) in a primary rain forests of the Chocó Region (Colombia)

Revista de Biología Tropical, 2015
Orchid bees are important keystone pollinators from the Neotropics. With the aim to study the relationships between orchid bees and their nectar and aromatic host species, we made systematic samplings of males across two conservation areas in the ...
