Segregation of phenotypic characteristics in hybrids of Triatoma brasiliensis species complex (Hemiptera, Reduviidae, Triatominae)
(2021-07-01)
There are currently 156 species, grouped into 18 genera and five tribes included in the subfamily Triatominae. All of them are potential vectors of Chagas disease. Triatoma is paraphyletic and the species of this genus ...
Feeding ecomorphologies in the fish genus Herichthys (Perciformes: Cichlidae) based on stomach content and lower pharyngeal jaw shape

Sexual dimorphism and diet segregation in the Black Skimmer Rynchops niger
(Nederlandse Ornithologische Unie, 2007-12)
Sexual segregation during foraging is common in birds and may occur at different temporal and spatial scales. In this study we explored the degree of sexual segregation in the Black Skimmer Rynchops niger by studying the ...
Does microhabitat segregation explain coexistence of globose cactus species?
(Cactus and Succulent Society of America, 2022-02)
The factors determining cactus species richness and distribution at broad scales are well understood; however, the mechanisms explaining these parameters at local scales are poorly known, particularly in mesic regions. The ...
Is there sexual segregation in habitat selection by Black-browed Albatrosses wintering in the south-west Atlantic?
(Csiro Publishing, 2021-01)
Sexual segregation in habitat use occurs when sexes differ in their use of the physical environment and is widely reported among seabirds. The Black-browed Albatross (Thalassarche melanophris) is one of the most abundant ...
Activity pattern segregation of carnivores in the High Andes.
(2009)
Intraguild competition may be reduced if ecologically similar species segregate temporally. Using data from 1,596 camera-trap photos, we present the 1st quantitative analyses of the activity patterns of Andean cats (Leopardus ...
Lack of segregation between two species of Chagas disease vectors.

Polymorphism for Y-linked suppressors of sex-ratio in two natural populations of Drosophila mediopunctata

Dynamic sequence evolution of a sex-Associated b chromosome in lake Malawi cichlid fish
(2017-01-01)
B chromosomes are extra chromosomes found in many species of plants, animals, and fungi. B chromosomes often manipulate common cellular processes to increase their frequency, sometimes to the detriment of organismal fitness. ...
Phylogenetic and adaptive components of the anuran advertisement call correlate with temporal species co-occurrence
(Oxford Univ Press, 2018-10-01)
Vocalization is one of the major means of communication in animal groups and is crucial in anuran mate recognition. Animal calls consist of spectral and temporal parameters, whose evolution can be influenced by environmental ...
