Influência da composição química foliar na colonização por larvas de Chironomidae (Diptera) durante a decomposição em riachos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2016-03-04)
With the purpose of elucidating some aspects concerning the influence of leaf chemical composition on Chironomidae (Diptera) larvae colonization and their role in decomposition, field experiments were carried out here ...
Reabsorción de nutrientes en especies siempreverdes y deciduas de Nothofagus
(2018)
Higher leaf nutrient concentrations, and similar resorption efficiencies, in
deciduous relative to evergreen trees is considered to determine higher
nutrient requirements in the former. However, evidence of woody perennials
of ...
Observation of leaf-cutting ants foraging on wild mushrooms
(Birkhauser Verlag Ag, 2012-05-25)
This study reports on the observation of an unusual behavior in leaf-cutting ants: foraging on wild mushrooms. A colony of Acromyrmex lundi in Buenos Aires (Argentina) was observed intensively harvesting basidiomes (mushroom ...
Diversity of metaxylem vessel elements in three Syagrus palms (Arecaceae) of different habits
(Sociedade Botânica do Brasil, 2011)
Elementos de vasos em monocotiledôneas apresentam diferenças morfológicas de acordo com o órgão onde ocorrem. Tais diferenças têm sido explicadas sobretudo de um ponto de vista evolutivo, com poucos dados acerca de como a ...
Sensitivity of leaf size and shape to climate: Global patterns and paleoclimatic applications
(Wiley Blackwell Publishing, Inc, 2011-05)
Paleobotanists have long used models based on leaf size and shape to reconstruct paleoclimate. However, most models incorporate a single variable or use traits that are not physiologically or functionally linked to climate, ...
Phenological diversity of maprounea guianensis (euphorbiaceae) in humid and dry neotropical forests
(2020-01-01)
Phenological diversity, seasonality and leaf longevity may affect leaf habits, reflecting plant responses to environmental conditions. Maprounea guianensis Aubl. is a widespread species in Brazil that is associated with ...
Neotropical freshwater crabs (Decapoda: Pseudothelphusidae) shred leaves
(2020)
Freshwater crabs are macroconsumers that are commonly found in Neotropical headwater streams that may play a key role in energy flow and nutrient cycling in detrital food webs. Although studies have examined the feeding ...
Morphological patterns and community organization in leaf-litter ant assemblages
(ECOLOGICAL SOC AMER, 2010)
We present a new approach to determine the number and composition of guilds, using the hyperdiverse leaf-litter ant fauna as a model, based on appropriate morphological variables and species co-occurrence null models to ...
