Susceptibility of three Eco-races of tropical Tasar silkworm to Antheraea mylitta cytoplasmic polyhedrosis virus (AmCPV)
Pathogenic infection in tasar silkworm, Antheraea mylitta Drury. is common and there is a breed specific response regarding tolerance. Observations reveal the possibility of differential response by haemocytes to microbial infection in different breeds. Hence, the susceptibility of three eco-races of tasar silkworm viz. Daba, Sarihan and Raily to Antheraea mylitta Cytoplasmic Polyhedrosis Virus...
متن کاملArms Races and Car Races
Evolutionary car racing (ECR) is extended to the case of two cars racing on the same track. A sensor representation is devised, and various methods of evolving car controllers for competitive racing are explored. ECR can be combined with co-evolution in a wide variety of ways, and one aspect which is explored here is the relative-absolute fitness continuum. Systematical behavioural differences ...
متن کاملGenetic Studies on Tropical Races of Silkworm (Bombyx mori) with Special Reference to Cross Breeding Strategy between Tropical and Temperate Races
In Japan a dozen of multivoltine strains had been maintained even for a short period from the second half of the 19th century to the first stage of the next centuryi0>. It seems to be likely to suppose that these multivoltine strains would be derived from the tropical races. Some of these multivoltine strains had practically been cultured for the production of silk threads and/or the exportatio...
متن کاملCompositional diversity of rehabilitated tropical lands supports multiple ecosystem services and buffers uncertainties
High landscape diversity is assumed to increase the number and level of ecosystem services. However, the interactions between ecosystem service provision, disturbance and landscape composition are poorly understood. Here we present a novel approach to include uncertainty in the optimization of land allocation for improving the provision of multiple ecosystem services. We refer to the rehabilita...
متن کاملBiomass accumulation in tropical lands with different disturbance histories: Contrasts within one landscape and across regions
Large areas of tropical forests have been converted to agricultural land and subsequently abandoned. If restoration can occur on these abandoned lands, it offers great potential for biodiversity recovery, carbon sequestration, and enhanced ecosystem services. To understand the interaction between different forms of anthropogenic degradation and restoration strategies we examined biomass accumul...
