Population Dynamics of Species with Gynogenetic Sibling Species
Models are formulated for the population dynamics of a monoecious or dioecious species with an all-female parthenogenetic sibling species which is also gynogenetic. Continuous, deterministic reproduction and mortality, a stationary age distribution, random mating, and limited sexual competence for all individuals are posited. It is also supposed that in the dioecious case males do not distingui...
متن کاملResource competition between sympatric sibling rotifer species
Mechanisms underlying competitive interactions are important in understanding the structure of planktonic communities, particularly the coexistence of similar species. Here we present experimental results of exploitative competition among three sympatric sibling species of the Brachionus plicatilis complex for two differently-sized species of food microalgae. These three rotifer species are to ...
متن کاملUltraviolet plumage reflectance distinguishes sibling bird species.
Realistic studies of plumage color need to consider that many birds can see near-UV light, which normal humans cannot perceive. Although previous investigations have revealed that UV-based plumage reflectance is an important component of various intraspecific social signals, the contribution of UV signals to inter-specific divergence and speciation in birds remains largely unexplored. I describ...
متن کاملMate recognition and reproductive isolation in the sibling species Spodoptera littoralis and Spodoptera litura
*Correspondence: Ahmed M. Saveer, Department of Plant Protection Biology, Box 102, SE-230 53 Alnarp, Sweden e-mail: [email protected] Mate recognition is crucial for reproductive isolation and for maintaining species integrity. Chemosensory-mediated sexual communication with pheromones is an essential component of mate recognition in moths. Confronted with sex pheromone stimuli released fr...
متن کاملSibling recognition and the development of identity: intersubjective consequences of sibling differentiation in the sister relationship.
Identity is, among other things, a means to adapt to the others around whom one must fit. Psychoanalytic theory has highlighted ways in which the child fits in by emulating important others, especially through identification. Alternately, the child may fit into the family and around important others through differentiation, an unconscious process that involves developing or accentuating qualiti...
