Electrophoretic Mobility and Larval Substrate within Species
Electromorphic variation among populations of Drosophila mojavensis, D. arizonensis and D. longicornis was examined for seven genetic loci. The average electrophoretic mobility for a population was used as the metric. D. mojauensis and D. arizonensis use larval substrates in different parts of their geographic ranges, while D. Zongicornis is more narrowly restricted to different species of the ...
متن کاملLarval dispersal in three coral reef decapod species: Influence of larval duration on the metapopulation structure
Most coral-associated decapod species have non-migratory adult populations and depend on their planktonic larvae for dispersal. This study examined the metapopulation structure of three decapod species with different pelagic larval duration (PLD) from twelve coral reef complexes of the Gulf of Mexico. The dispersion of larvae was analyzed through the use of a realistic numerical simulation of t...
متن کاملAnopheline Larval Habitats Seasonality and Species Distribution: A Prerequisite for Effective Targeted Larval Habitats Control Programmes
BACKGROUND Larval control is of paramount importance in the reduction of malaria vector abundance and subsequent disease transmission reduction. Understanding larval habitat succession and its ecology in different land use managements and cropping systems can give an insight for effective larval source management practices. This study investigated larval habitat succession and ecological parame...
متن کاملIdentification of asteroid genera with species capable of larval cloning.
Asexual reproduction in larvae, larval cloning, is a recently recognized component of the complex life histories of asteroids. We compare DNA sequences of mitochondrial tRNA genes (Ala, Leu, Asn, Pro, and Gln) from larvae in the process of cloning collected in the field with sequences from adults of known species in order to identify asteroid taxa capable of cloning. Neighbor-joining analysis i...
متن کاملLarval pupation site preference in a few species of Drosophila.
Larval pupation site preference (PSP) is an important event in preadult development. The PSP was studied on the basis of the number of larvae pupated at different sites in the cultures. The results revealed that the larval PSP in different species of Drosophila varies significantly at different sites. The sympatric species also differ in their PSP and the pupation behaviour does not correspond ...
