Towards an actualistic view of the Crato Konservat-Lagersta & uml;tte paleoenvironment: A new hypothesis as an Early Cretaceous (Aptian) equatorial and semi-arid wetland
(Elsevier B.V., 2021-05-01)
An alternative hypothesis concerning the paleoecological and paleoenvironmental depositional conditions of the Crato Konservat-Lagersta?tte (CKL), Crato Formation, Aptian, NE Brazil, one of the most extraordinary Gondwana ...
Diversidade e conservação de Aegla leach, 1820 (Crustacea, anomura) em área prioritária para preservação
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2022-09-16)
Freshwater crustaceans of the genus Aegla Leach, 1820 are important components of the fauna of rivers,
streams, lakes, and caves of several countries in South America, where they are endemic. Currently, the genus
is ...
Macroalgae ecosystem engineering effects mediated by an invasive reef-builder polychaete in a Southwestern Atlantic coastal lagoon
(Elsevier Science, 2021-01)
Macroalgae in Mar Chiquita coastal lagoon (37◦ 40′ S, 57◦ 23′ W, Argentina) settle on small-hard substrates on sediments and complex reef-like structures with tubes and crevices of the invader polychaete Ficopomatus ...
Effects of the alien algae Undaria pinnatifida (Phaeophyceae, Laminariales) on the diversity and abundance of benthic macrofauna in Golfo Nuevo (Patagonia, Argentina): Potential implications for local food webs
(Springer, 2011-07)
Changes in macroalgal community structure caused by invasive seaweeds have strong impacts on the associated macrofauna due to the role of macroalgae as autogenic ecosystem engineers. This study investigates the effect of ...
The Phyllotis xanthopygus complex (Rodentia, Cricetidae) in central Andes, systematics and description of a new species
(Wiley Blackwell Publishing, Inc, 2021-11)
Phyllotis Waterhouse 1837 is one of the most studied genera of South American cricetid rodents. As currently understood, it includes 20 small to medium-sized species of predominantly rocky habitats. Among them, populations ...
A plasticidade acústica de uma população de Boto - Cinza, Sotalia Guianensis (Van Banédén, 1864) (Cetacea, Delphinidae), na região Nordeste do Brasil
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM PSICOBIOLOGIA, 2014-11-20)
The environmental characteristics can modify the acoustics of a species due to habitat, time of day and year. Therefore, this study investigated the relationships between seasons, tide, daily cycle of tides, times of day ...
Filogeografia do complexo Ischnocnema lactea e Ischnocnema holti (Anura, Brachycephalidae), sudeste do Brasil
(Universidade Estadual Paulista (Unesp), 2015-11-30)
Among the different environments of the Atlantic forest, the high altitude areas are habitat for some endemic species of amphibians. Such species can provide evidence to test the hypothesis that mountainous environments ...
Uso do habitat, padrões de movimento e gasto energético de micos-leões-pretos (Leontopithecus chrysopygus)
(Universidade Estadual Paulista (Unesp), 2022-08-25)
Alterações na estrutura das florestas decorrentes da degradação do habitat podem levar a alterações na movimentação de animais que dependem desses ambientes, afetando seu balanço energético e, em última análise, sua taxa ...
Partitioning the net effect of host diversity on an emerging amphibian pathogen
(Royal Soc, 2014-11-22)
The 'dilution effect' (DE) hypothesis predicts that diverse host communities will show reduced disease. The underlying causes of pathogen dilution are complex, because they involve non-additive (driven by host interactions ...
Temperate snake community in South America: Is diet determined by phylogeny or ecology?
(Public Library of Science, 2015-05)
Communities are complex and dynamic systems that change with time. The first attempts to explain how they were structured involve contemporary phenomena like ecological interactions between species (e.g., competition and ...
