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.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Blueberry pollination in southern Brazil and their influence on fruit quality

Revista Brasileira de Fruticultura, 2011
Blueberry (Vaccinium ashei) is a relatively new crop in cultivation under Southern Brazil conditions. The first collection introduced in the area was formed by rabbiteye cultivars which need insect pollinators and also pollinizers.

INSETOS DIPTERAS COMO POLINIZADORES EM ORCHIDACEAE

Revista Uningá, 2015
A polinização é o principal processo de reprodução emplantas, e os insetos são um dos grupos mais atuantes nessemecanismo. Nas orquídeas os membros da ordem Hymenopterase destacam, entretanto dípteras, lepidopteras ecoleopteras também exercem este papel.

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 ...

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.
