In particular eight scenarios are developed using graph theory to identify propagule source patches and fishing and exploitation activities as costs-in-use for local population.
Changes in vegetation and fauna during the Early Holocene provoked new adaptations in subsistence behavior, oriented toward the fishing and exploitation of marine mammals in arctic regions.
Humans are one of the dog conch's main predators, subjecting the species to intensive fishing and exploitation.
We then describe the underlying biological and angling fishery processes that determine the population dynamics, fishing intensity, exploitation patterns, and resulting selection pressures.
Dr. Lubchenco has documented enormous dead zones in oceans that have resulted from climate change and has advocated placing vast ocean areas off-limits to fishing and mineral exploitation.
The problem of fishing-induced evolution requires attention because it might be widespread, as most commercially harvested fish stocks experience intense exploitation rates, with fishing mortality being up to four times higher than the natural mortality (Mertz and Myers 1998).
Here, we measured the wariness of two families of coral reef fishes in both fished areas and marine reserves embedded within a fished seascape along an exploitation gradient ranging from wilderness sites (Chagos) to heavily fished areas (the Philippines).
Fishing, fish processing, industrial exploitation of several marine species, and development of improved fishing gear continue during the Byzantine period [253].
Significantly, it prohibits fishing and other resource exploitation so as to protect such endangered species as the short-tailed albatross and the remaining population of Hawaiian monk seals, as well as the long-living black coral (some of which are estimated to be 4,000 years old).
The most serious threats to vertebrates are overfishing, bycatch of seabirds, marine mammals, and turtles, as well as degradation of coastal and marine environments, urban pollution, and pollution from industrial activities such as fishing and oil exploration, exploitation, and transport.
