Innate response based on visual cues of sympatric and allopatric predators in Nile tilapia
(2019-07-01)
Predators are an important selective pressure for prey, and responses to visual exposure to non-predators and to allopatric and sympatric predators may assist the understanding of how prey animals recognize and distinguish ...
Unravelling cryptic species of freshwater snails (Caenogastropoda, Truncatelloidea) in the Loa River basin, Atacama Desert
(2016)
Species recognition in freshwater snails of the genus Heleobia Stimpson, 1865 in the Loa River basin is a difficult task to perform because these snails are similar in shell morphology. In this complex hydrological network, ...
Allopatric speciation in ticks: genetic and reproductive divergence between geographic strains of Rhipicephalus (Boophilus) microplus
(BioMed Central, 2009-02)
Background: The cattle tick, Rhipicephalus (Boophilus) microplus, economically impact cattle industry in tropical and subtropical regions of the world. The morphological and genetic differences among R. microplus strains ...
Biological differences between two allopatric populations of Amblyomma cajennense (Acari: Ixodidae) in Argentina
(Springer, 2011-04)
The fertility of hybrids from two distinct populations of Amblyomma cajennense from different ecological regions of Northern Argentina was analyzed. Two colonies of A. cajennense from El Rey National Park (RNP), Salta ...
New Records Reveal the Actual Distribution of Cratomelus meritus Gorochov (Orthoptera: Anostostomatidae), a Giant Red Cricket from Chile
(Kluwer Academic Publishers, 2015)
© 2015, Sociedade Entomológica do Brasil. The geographic distribution of the red cricket Cratomelus meritus Gorochov had remained unknown until now due to mislabeling and lack of new records. The aim of this short communication ...
Similitudes y diferencias en el nicho realizado de dos poblaciones alopátricas de una abeja solitaria bajo variabilidad ambientalSimilarities and differences in the realized niche of two allopatric populations of a solitary bee under environmental variability
(EDP Sciences, 2020-03)
We studied the realized niche of two distant allopatric wool-carder bee populations (bee-plant interaction and reproductive biology in weather variability). In one population, we analyzed the direct and indirect effects ...
Environmental conditions drive vocal variation in the scaled dove (Columbina squammata)
(2022-01-01)
Variations in communication systems profoundly affect bird evolution. Vocalizations mediate species recognition and therefore intra-specific variation may lead to reproductive isolation, ultimately resulting in speciation. ...
Reproductive isolation between sympatric and allopatric Brazilian populations of Lutzomyia longipalpis s.l. (Diptera: Psychodidae)
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2019)
