Abstract The unique Himalayan ecosystems are repositories to the wild populations of diverse flora and fauna. high value medicinal aromatic plant species (MAPs) an example same. Since time immemorial, these MAPs have been traditionally used by local inhabitants eventually developed a market all over world. Increasing demand engenders over-extraction species, unsustainable collection further cat...

Ecology Letters (2011) 14: 1025-1034 ABSTRACT: Evolutionary changes in natural populations are often so fast that the evolutionary dynamics may influence ecological population dynamics and vice versa. Here we construct an eco-evolutionary model for dispersal by combining a stochastic patch occupancy metapopulation model with a model for changes in the frequency of fast-dispersing individuals in...

Aggregation can confer advantages in animal foraging, defense, and thermoregulation. There is a tight connection between the evolution of insect sociality and a highly effective immune system, presumably to inhibit rapid disease spread in a crowded environment. This connection is less evident for animals that spend only part of their life cycle in a social environment, such as noneusocial grega...
