The ecohydrology of ecosystem transitions: a meta-analysis
(Wiley, 2014-06)
A vast body of literature demonstrated that anthropogenic disturbances such as overgrazing and fire are key drivers of abrupt transition between vegetation types in ecosystems. In this study, we propose that the hydrological ...
Temporal variations of larval digenean assemblages parasitizing Heleobia Parchappii (Mollusca: Cochliopidae) in two shallow lakes from the Buenos Aires province, Argentina
(Fundaçao Zoobotanica Rio Grande Sul, 2019-07)
The larval digenean assemblages in snail hosts are influenced by biotic and abiotic factors and by environmental disturbances due to human activities. Given their susceptibility to different types of impact, they can be ...
Determinants of reef fish assemblages in tropical Oceanic islands
(2019)
Diversity patterns are determined by biogeographic, energetic, and anthropogenic factors, yet few studies have combined them into a large‐scale framework in order to decouple and compare their relative effects on fish ...
Relationship of Neotropical otter vestiges with environmental and anthropogenic factorsRelação entre os vestígios de lontra neotropical e fatores ambientais e antropogênicos
(Instituto Nacional de Pesquisas da AmazôniaBrasilINPA, 2020)
Combined analysis of trace elements and isotopic composition of particulate organic matter in suspended sediment to assess their origin and flux in a tropical disturbed watershed
(Elsevier B.V., 2016-11-01)
Approximately 40% of the volume of domestic sewage generated in the Sao Paulo State is untreated and released into water bodies, causing serious pollution problems that affect the water quality and especially the suspended ...
Immunological and health-state parameters in the Patagonian rockfish Sebastes oculatus. Their relation to chemical stressors and seasonal changes
(Academic Press Ltd - Elsevier Science Ltd, 2016-01)
We present the results of a field study that evaluates whether exposure to anthropogenic pollution impacts immunological and health-state parameters of wild marine fish during the breeding and non-breeding periods. We ...
Stream fish metacommunity organisation across a Neotropical ecoregion: The role of environment, anthropogenic impact and dispersal-based processes
(2020-05-01)
Understanding how assemblages are structured in space and the factors promoting their distributions is one of the main goals in Ecology, however, studies regarding the distribution of organisms at larger scales remain ...
