Ventilatory frequency indicates visual recognition of an allopatric predator in naive Nile tilapia
(Elsevier B.V., 2003-01-31)
Perceiving a possible predator may promote physiological changes to support prey 'fight or flight'. In this case, an increase in ventilatory frequency (VF) may be expected, because this is a way to improve oxygen uptake ...
Reproductive isolation between sympatric and allopatric Brazilian populations of Lutzomyia longipalpis s.l. (Diptera: Psychodidae)

Differences in mating behavior between two allopatric populations of a Neotropical scorpion
(Elsevier Gmbh, 2017-08)
Courtship and mating behavior generally evolve rapidly in diverging populations and species. The adaptation to different environments may cause behavioral divergence in characteristics involved in mate choice. Our objective ...

Molecular diversity and historical phylogeography of the widespread genus Mastiglanis (Siluriformes: Heptapteridae) based on palaeogeographical events in South America
(Oxford Univ Press, 2021-12-16)
The catfish family Heptapteridae, endemic in the Neotropical region, is composed of small- to medium-sized species. The genus Mastiglanis was monotypic until very recently and is often misidentified as Imparfinis because ...
Meiotic differentiation in two allopatric population groups of the tetraploid frog Odontophrynus americanus from Argentina
(British Herpetological Society, 2008-10)
The Odontophrynus americanus species complex is widely distributed in South America and is formed of diploid and tetraploid cryptic species. We studied the meiotic prophase stages of two allopatric tetraploid population ...
Amblyomma cajennense (Fabricius, 1787) (Acari: Ixodidae), the Cayenne tick: phylogeography and evidence for allopatric speciation
(BioMed Central, 2013-12)
Background: Amblyomma cajennense F. is one of the best known and studied ticks in the New World because of its very wide distribution, its economical importance as pest of domestic ungulates, and its association with a ...
