Minimal prezygotic isolation between ecologically divergent sibling species. [PDF]

Biol J Linn Soc Lond, 2021
AbstractDivergence in mating signals typically accompanies speciation. We examine two ecologically divergent sibling species of crickets to assess the degree and timing of the evolution of prezygotic reproductive isolation. Gryllus saxatilis occurs in rocky habitats throughout western North America with long-winged individuals capable of long-distance ...

Simple and Complex Centromeric Satellites in Drosophila Sibling Species. [PDF]

Genetics, 2018
Abstract Centromeres are the chromosomal sites of assembly for kinetochores, the protein complexes that attach to spindle fibers and mediate separation of chromosomes to daughter cells in mitosis and meiosis. In most multicellular organisms, centromeres comprise a single specific family of tandem repeats—often 100–400 bp in length—found ...

Malaria vector sibling species distribution in different endemic districts of Punjab, India

Journal of Vector Borne Diseases, 2023
Background & objectives: Malaria transmission in Punjab, India is mainly seasonal with variation in its endemicity that may be due to varying vector behaviour in different areas of the state, primarily attributed to the existence of sibling species ...

Prevalence of sibling-species of Anopheles (Cellia) fluviatilis complex in Himachal Pradesh, India

Journal of Vector Borne Diseases, 2021
Background & objectives: Malaria is one of the most infectious and life-threatening vector borne disease in the tropics. Climate change can significantly influence malaria epidemiology and expansion of malaria vectors to hilly regions of Himachal Pradesh

Mitochondrial-COII sequence polymorphism reflects spatial genetic clustering of Anopheles culicifacies sibling species E in Sri Lanka

Journal of Vector Borne Diseases, 2020
Background & objectives: Malaria infects around 216 million people annually with estimated 445,000 deaths globally. Anopheles culicifacies is the vector of malaria in Sri Lanka, a complex of five morphologically identical sibling species of which precise

Molecular identification of sibling species of the members of the Anopheles punctulatus group in the Jayapura regency, Papua province, Indonesia

International Journal of Infectious Diseases, 2022
Purpose: Precise mosquito species identification is an essential step for proper management and control of malaria vectors. Misidentification of members in the Anopheles punctulatus group, some which are primary malaria vectors in Papua (Indonesia ...

Onisimus turgidus (Sars, 1879) (Amphipoda, Uristidae), an overlooked amphipod from sea anemones in Northern Norway

European Journal of Taxonomy, 2020
Two Norwegian uristid amphipods, obligate associates of sea anemones, have for a long time been confused sub nomine Onisimus normani Sars, 1890. In reality this species only occurs in south Norway, while the north-Norwegian material belongs to O ...

Sibling Species in Artemia (Crustacea:Branchiopoda) [PDF]

Evolution, 1968
The species Artemia salina (L.) is composed of a group of differentiated units, which cannot interbreed because of differences in the manner of reproduction (Artom, 1931; Barigozzi, 1944, 1946, 1957). Artemia salina has, therefore, been termed by Artom "specie collettiva" also taking into consideration the different ploidy degrees.
