An international team of researchers from the Clemente Estable Institute of Biological Research (Uruguay), the National University of Cordoba (Argentina) and Brazil’s Butantan Institute is conducting a study on spiders in the Amazon region, in the state of Para, northern Brazil. This was reported by
Diario La R, a partner of TV BRICS.
The project, funded by Uruguay’s National Agency for Innovation and Research, focuses on examining the genetic, morphological and behavioural diversity of South American spiders, particularly those of the subfamily Allocosinae, commonly known as wolf spiders.
The main aim of the study is to understand how environmental factors influence physical, genetic and behavioural changes, and how these shifts may contribute to the emergence of new species.
The specimens under investigation include Allocosa senex, which inhabits sandy environments such as beaches and riverbanks, and Paratrochosina amica, typically found in grasslands. Both species are distributed across Chile, Argentina, Brazil and Uruguay.
In addition to fieldwork in the Amazon, samples are being collected from various ecosystems in Uruguay to compare adaptations and variations between different environments.
