Biodiversity threats are one of the major concerns of today's intellectuals. These threats arise
due to environmental problems that appear both due to natural processes as well as …

Atlantic salmon (Salmo salar) is an economically and culturally important species. Norway
has more than 400 watercourses with Atlantic salmon and supports a large proportion of the …

While population declines can drive the loss of genetic diversity under some circumstances,
it has been unclear whether this loss is a general consequence of overharvest in highly …

We review the effects of fishing on benthic fauna, habitat, diversity, community structure and
trophic interactions in tropical, temperate and polar marine environments and consider …

In upwelling ecosystems, there is often a crucial intermediate trophic level, occupied by
small, plankton-feeding pelagic fish dominated by one or a few schooling species. Their …

In many marine species, high levels of gene flow ensure that the genetic signal from
population differentiation is weak. As a consequence, various errors associated with …

This topical and exciting textbook describes fisheries exploitation, biology, conservation and
management, and reflects many recent and important changes in fisheries science. These …

While the impacts of high exploitation on fish populations and aquatic ecosystems are well-
documented for commercial fishing, particularly in the marine environment, the potential …

Partial migration, where only some individuals from a population migrate, has been widely
reported in a diverse range of animals. In this paper, what is known about the causes and …

Human harvest of animals in the wild occurs in terrestrial and aquatic habitats throughout
the world and is often intense. Harvest has the potential to cause three types of genetic …
