A mutation of Drosophila melanogaster whose only known effect is the rescue of otherwise lethal interspecific hybrids has been characterized. This mutation, Hmr, maps to 1-31.84 (9D1-9E4). Hmr may be the consequence of a P element insertion. It rescues hybrid males from the cross of D. melanogaster females to males of its three sibling species, D. simulans, D. mauritiana and D. sechellia. This ...

Anopheles subpictus has been recognised as an important vector of malaria in Sri Lanka and some other countries like Malaysia and Maldives. It has been found to play an important role in malaria transmission as a secondary vector in certain parts of Odisha and coastal areas of south India. An. subpictus is a widely distributed mosquito species that breeds in a variety of fresh as well as saline...

Knowledge about sibling relationships is used in genetic epidemiology, conservation biology, and animal management. For example, knowledge of the genetic relationships among individuals is critical for estimating heritabilities of quantitative characters, for characterizing mating systems and fitness, and for managing populations of endangered species. When parental data are available, sibling ...

293 Drosophila albomicans (2n = 6) and D. nasuta (2n = 8) belong to the D. nasuta subgroup of the D. immigrans species group (Duda 1940, Wilson et al. 1969). According to molecular evidence, this sibling species pair is young and diverged < 0.5 million yrs ago (Ma) (Chang et al. 1989, Bachtrog 2006). During the divergence of these sibling species, hereditary materials in nuclear (n)DNA and mito...

Examination of genetic and ecological relationships within sibling species complexes can provide insights into species diversity and speciation processes. Alpheus angulatus and A. armillatus, two snapping shrimp species with overlapping ranges in the north-western Atlantic, are similar in morphology, exploit similar ecological niches and appear to represent recently diverged sibling species. We...

The interaction between sibling species that share a zone of contact is a multifaceted relationship affected by climate change [1, 2]. Between sibling species, interactions may occur at whole-organism (direct or indirect competition) or genomic (hybridization and introgression) levels [3-5]. Tracking hybrid zone movements can provide insights about influences of environmental change on species ...
