Nectários extraflorais em Luffa cylindrica (L.) M. Roem (Cucurbitaceae): anatomia e respostas morfofisiológicas em função do status nutricional e herbivoria
(Universidade Federal de Minas GeraisUFMG, 2016-02-29)
Extrafloral nectaries (EFNs) are secretory structures commonly involved in the indirect defence of plants. In Luffa cylindrica, these structures occur in leaves, stems and fruits. 3 In leaves, EFNs are present on the lower ...
Predation on artificial caterpillars following understorey fires in human-modified Amazonian forests
(2022-01-01)
Tropical forests are facing several impacts from anthropogenic disturbances, climate change, and extreme climate events, with potentially severe consequences for ecological functions, such as predation on folivorous ...
Papel da incidência de trepadeiras e herbivoria no desempenho de comunidades vegetais restauradas da Caatinga
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ECOLOGIA, 2019-04-30)
Semi-arid ecosystems are highly susceptible to landscape degradation. Among them, the Caatinga is one of the most vulnerable regions. Caatinga restoration has advanced with new successful methods like the use of facilitation ...
Sodium-specific foraging by leafcutter ant workers (Atta cephalotes, Hymenoptera: Formicidae)
(WILEY-BLACKWELLHOBOKEN, 2012)
1. Sodium is often a limiting nutrient for terrestrial animals, and may be especially sought by herbivores. Leafcutter ants are dominant herbivores in the Neotropics, and leafcutter foraging may be affected by nutritional ...
Interactive effects of grazing and environmental stress on macroalgal biomass in subtropical rocky shores: Modulation of bottom-up inputs by wave action
(2015-02)
In contrast to what is observed in most temperate regions, perennial macroalgae are rare at the mid intertidal level of tropical and subtropical shores, and energy transfer through benthic herbivores largely relies on the ...
Variable retention harvesting influences biotic and abiotic drivers of regeneration in Nothofagus pumilio southern Patagonian forests
(Elsevier Science, 2013-01)
Understanding regeneration processes is important for implementing new silvicultural treatments that rely on natural regeneration from seed. Nevertheless, integrated, flower-to-sapling studies of the regeneration cycle ...
Food selection by a mangrove crab: Temporal changes in fasted animals
(2013-01-01)
The feeding choices of the mangrove crab Ucides cordatus for various mangrove plant leaves (Avicennia schaueriana, Laguncularia racemosa, and Rhizophora mangle) at different ages (mature, senescent pre-abscission, and ...
