Effects of irradiance and spectral composition on the establishment of macroalgae in streams in southern Brazil
(Edp Sciences S A, 2012-01-01)
The relative effects of irradiance and spectral composition on the colonization and development of macroalgal communities were examined in four streams exposed to full sunlight in southern Brazil. A set of solar filters ...
Predicting the seasonal dynamics of bird communities along an urban-rural gradient using NDVI
(Elsevier Science, 2018-04-23)
The normalized difference vegetation index (NDVI) is a strong and widely used proxy for bird species richness in urban environments. However, its potential to predict composition and seasonal dynamics of bird communities ...
Ouvir, interagir e criar: a composição musical como oportunidade de humanização das relações sociais em uma orquestra comunitária
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Educação - PPGECâmpus São Carlos, 2018-02-26)
This research had as its theme the creation of composition and musical arrangement for a community orchestra, whose participants had a significant diversity of mastery and musical knowledge. The aim of this work was to ...
The influence of temperature and pH on bacterial community composition of microbial mats in hot springs from Costa Rica
(2019)
We used the 16S rRNA gene pyrosequencing approach to investigate the microbial diversity and community composition in several Costa Rican hot springs alongside the latitudinal axis of the country, with a range of temperatures ...
Edge effects as the principal cause of area effects on birds in fragmented secondary forest
(WILEY-BLACKWELL, 2010)
Bird communities in tropical forests are strongly affected by both patch area and habitat edges. The fact that both effects are intrinsically confounded in space raises questions about how these two widely reported ecological ...
Calliphoridae (Diptera) in Human-Transformed and Wild Habitats: Diversity and Seasonal Fluctuations in the Humid Chaco Ecoregion of South America
(Entomological Society of America, 2019-01)
A temporal study of the Calliphoridae fauna was conducted in five different types of habitats in the Humid Chaco ecoregion: an urban settlement, a cattle farm, an alfalfa crop, a savanna, and a forest. Research was carried ...
Environmental filters and biotic interactions drive species richness and composition in ecotone forests of the northern Brazilian Amazonia
(Museu Paraense Emílio GoeldiBrasil, 2021-09-07)
The structure of tree communities in tropical forests depends on environmental filters and biotic interactions such as competition and facilitation. Many ecotone forests in Northern Amazonia are intriguingly populated by ...
Taxonomic and functional threshold responses of vertebrate communities in the Atlantic Forest Hotspot
(2021-05-01)
Ecological thresholds are an indicator of rapid and non-linear changes along both natural habitat and land-use gradients. Thus, they can be used to quantify biodiversity responses to human-induced environmental change. We ...
Vinasse and Its Influence on Ant (Hymenoptera: Formicidae) Communities in Sugarcane Crops
(Oxford Univ Press Inc, 2017-01-27)
Sugarcane is an important crop within the Brazilian socioeconomic landscape. There is a constant need for approaches to increase sustainability at all steps of the production chain. Irrigating sugarcane crops with vinasse ...
Changes in ectomycorrhizal fungal community composition and declining diversity along a 2-million-year soil chronosequence
(Blackwell Publishing, 2016-10)
Ectomycorrhizal (ECM) fungal communities covary with host plant communities along soil fertility gradients, yet it is unclear whether this reflects changes in host composition, fungal edaphic specialization or priority ...
