Megaherbivores suppress precipitation‐driven plant irruptions in a tropical savanna

Ecosphere, Volume 16, Issue 5, May 2025.
Abstract Irruptions in plant and animal populations are not uncommon, but the factors underlying irruptions are rarely explored quantitatively. In addition, it has been suggested that these irruptions may be reduced by predators or herbivores, but there is a paucity of controlled experimental evidence.

Breeding strategies for Brachiaria spp. to improve productivity - an ongoing project

Tropical Grasslands - Forrajes Tropicales, 2014
Two strategies have been used in the breeding of Brachiaria (syn. Urochloa) to produce new cultivars. The first involves exploring the natural variability existing in nature, which is the selection of ecotypes, mostly apomicts, from the diversity in germplasm banks.

Characterization of resistance to adult spittlebugs (Hemiptera: Cercopidae) in Brachiaria spp.

Journal of economic entomology, 2013
Nymphs and adults of several spittlebug (Hemiptera: Cercopidae) species are key pests of forage brachiariagrasses (Brachiaria spp.) in tropical America. To support current breeding programs, a series of experiments aimed at characterizing the mechanisms of resistance to adult feeding damage were carried out.
