An assemblage of large-sized insect traces in paleosols from the middle miocene of northern Patagonia related to the climatic optimum
(Pergamon-Elsevier Science Ltd, 2021-08)
A new assemblage of large insect trace fossils is recognized in paleosols of the middle Miocene pyroclastic deposits from extra-Andean north Patagonia. This assemblage includes Racemusichnus jacobacciensis igen. isp. nov., ...
Inter-annual fluctuation in the population structure of an estuarine fish: Influence of environmental drivers
(Elsevier Science, 2021-06)
The environmental influence on the long-term variations of fish population structure, mainly that which drives the movements between segregated life stages, is not yet fully understood in estuarine systems. As a case study, ...
Thresholds in the relationship between functional diversity and patch size for mammals in the Brazilian Atlantic Forest
(Wiley-Blackwell, 2015-12-01)
Patch size affects abundance and diversity of mammal species, but there is little information on threshold regarding this relationship or relating it to functional diversity. Therefore, we aimed with this study to (1) ...
Tooth Size Variation in Assemblages of Tremacyllus (Hegetotheriidae, Notoungulata): Insights into Geographical Gradients, Systematics, and Sexual Dimorphism
(Springer, 2021-09)
Tooth size variation within fossil assemblages can be associated with intra- or interspecific variation, functional, developmental, and geographical factors, and/or sexual dimorphism. Understanding these sources of variation ...
Testing for functional convergence of temperate rainforest tree assemblages in Chile and New Zealand
(Taylor & Francis, 2016)
An important tenet of biogeography and comparative ecology is that disjunct assemblages in similar physical environments are functionally more similar to each other than to assemblages from other environments. Temperate ...
The influence of habitat structure on fish assemblages in Amazonian streams of Machado river basin
(Universidad de Costa Rica, 2017)
Subtidal benthic macroinfaunal assemblages in tropical estuaries: Generality amongst highly variable gradients
(2012)
South American estuaries are frequently not included in the search for general ecological models and studies dealing with biological assemblages in estuaries frequently do not sample the entire salinity gradient. We sampled ...
Hypogaeic anti epigaeic ant (Hymenoptera: Formicidae) assemblages of atlantic costal rainforest and dry mature and secondary amazon forest in Brazil: Continuums or communities
(2000-12-01)
Meat, flour and sugar baits were used on the soil surface and buried to examine species composition of the ant fauna in three separate tropical forests in Brazil, and to control for the effect of the regional faunal pool. ...
