Niche divergence among closely related taxa provides insight on evolutionary patterns of ticks
(Wiley, 2021-09)
Aim: Understanding the degree to which closely related taxa diverge in their niche traits could provide insight on their evolutionary patterns, as well as shed some light on the mechanisms underpinning broad-scale biogeographic ...
The right tool for the right question: contrasting biogeographic patterns in the notothenioid fish Harpagifer spp. along the Magellan Province
(Royal Soc., 2022)
Molecular-based analysis has become a fundamental tool to understand the role of Quaternary glacial episodes. In the Magellan Province in southern South America, ice covering during the last glacial maximum (20 ka) radically ...

Genomics at the evolving species boundary
Molecular studies on hybridization date back to Dobzhansky who compared chromosomal banding patterns to determine if interspecific gene flow occurred in nature [1]. Now, the advent of high-throughput sequencing provides ...
Coordenadas geográficas de Turnera sidoides subsp. carnea
The lowlands of mid-latitude South America comprise complex temperate ecoregions characterized by a unique biodiversity. However, the processes responsible for shaping its species diversity are still largely unknown. Turnera ...
Morphological and genetic differentiation within the southernmost vector of chagas disease: Triatoma patagonica (hemiptera-reduviidae)
(Public Library of Science, 2016-12)
The epidemiological importance of Chagas disease vectors largely depends on their spreading ability and adaptation to domestic habitats. Triatoma patagonica is a secondary vector of Chagas disease endemic of Argentina, and ...
A lowland story: behaviour and phenotypic integration in a cline between two incipient species of neotropical dart-poison frogs
(Universidad de los AndesBiologíaFacultad de CienciasDepartamento de Ciencias Biológicas, 2021)
In the animal world there are many strategies to avoid predation. One of them is colouring as a form of protection, either with aposematism or crypsis. These are subject to different pressures such as natural selection, ...
Modelos dinâmicos de assembléia
(2010-07-20)
The structure of an ecological community is shaped by several temporally varying mechanisms. Such mechanisms depend in a large extent on species interactions, which are themselves manifestations of the community's own ...

Reproductive biology of Macrobrachium amazonicum (Heller, 1862) populations with distinct phenotypes in Neotropical reservoirs during the 'El Niño' event
(2019-01-01)
Here, we investigated the reproductive biology (frequency and distribution patterns of ovigerous females, fecundity, reproductive output and egg size and volume) of Macrobrachium amazonicum in four populations living in ...
