Operational interactions between South American sea lions and gillnet fishing in southern Brazil
Aquatic Conservation: Marine and Freshwater Ecosystems - Tập 26 Số 1 - Trang 108-120 - 2016

Abstract This study describes operational interactions between coastal gillnet fishing and South American sea lions (Otaria flavescens) off the southern Brazilian coast. In total, 263 onboard surveys were carried out during three periods between 1992 and 2012 in fishing boats from two harbours on the northern coast of Rio Grande do Sul State: Passo de Torres (29°19'S; 49°43'W) and Imbé (29°58'S; 5... hiện toàn bộ
Have we neglected the societal importance of sand dunes? An ecosystem services perspective
Aquatic Conservation: Marine and Freshwater Ecosystems - Tập 20 Số 4 - Trang 476-487 - 2010
Mark Everard, Laurence Jones, Bill Watts
Abstract Coastal sand dunes are widespread worldwide, including around the coasts of the British Isles and Europe, providing a wide range of functions some of which are recognized for their socio‐economic benefits. In some localities, their contribution to coastal defence and to tourism and regional character have been acknowledged in local plans, but this is far from ubiquitous. A rapid assessmen... hiện toàn bộ
Geophysical approaches to the classification, delineation and monitoring of marine habitats and their communities
Aquatic Conservation: Marine and Freshwater Ecosystems - Tập 13 Số 1 - Trang 77-90 - 2003
John C. Roff, Mark E. Taylor, Josh Laughren
Abstract If marine environments are to be systematically protected from the adverse effects of human activities, then identification of the types of marine habitats and the communities they contain, and delineation of their boundaries utilizing a consistent classification is required. Human impacts on defined communities can then be assessed, the ‘health’ of these communities can be monitored, and... hiện toàn bộ
The Alliance for Freshwater Life: A global call to unite efforts for freshwater biodiversity science and conservation

Weyl
Abstract Global pressures on freshwater ecosystems are high and rising. Viewed primarily as a resource for humans, current practices of water use have led to catastrophic declines in freshwater species and the degradation of freshwater ecosystems, including their genetic and functional diversity. Approximately three‐quarters of the world's inland wetlands have been lost, one‐third of the 28 000 fr... hiện toàn bộ
The role of introduced species in the decline of a highly endemic fish fauna in Central Mexico
Aquatic Conservation: Marine and Freshwater Ecosystems - Tập 28 Số 6 - Trang 1384-1395 - 2018
Pablo Gesundheit, Constantino Macı́as Garcı́a
Abstract Central Mexico, home to a unique and imperilled freshwater fish fauna, high in endemism, is also a very densely populated region with considerable human activity. Aquatic systems in the region have been heavily disturbed by human activity in the form of species introductions, pollution, and habitat modification, which has resulted in the extirpation of native fishes and the alteration of ... hiện toàn bộ
Applications and future challenges in marine species distribution modeling
Aquatic Conservation: Marine and Freshwater Ecosystems - Tập 21 Số 1 - Trang 92-100 - 2011
Johannes Dambach, Dennis Rödder
Abstract Anthropogenic climate change affects both phenology and distribution patterns of the world's biota including marine species. During the last decade, species distribution models have been more frequently used to assess the potential distributions of species and possible effects of climate change. However, unlike for terrestrial species, there have been few investigations assessing climate ... hiện toàn bộ
High mortality of adult female Magellanic penguins by gillnet fisheries in southern Brazil
Aquatic Conservation: Marine and Freshwater Ecosystems - Tập 29 Số 10 - Trang 1657-1664 - 2019
Carine O. Fogliarini, Leandro Bugoni, Manuel Haimovici, Eduardo R. Secchi, Luís Gustavo Cardoso
Abstract Bycatch in gillnet fisheries is one of the main threats to several penguin species. Magellanic penguins (Spheniscus magellanicus) are caught by gillnets during their wintering in southern Brazil. However, current information is based only on a small number of sets observed during a single fishing trip. This study assesses bycatch rates of bottom and drift gillnets operating in southern Br... hiện toàn bộ

Whole‐community facilitation by beaver: ecosystem engineer increases waterbird diversity
Aquatic Conservation: Marine and Freshwater Ecosystems - Tập 24 Số 5 - Trang 623-633 - 2014
Petri Nummi, Sari Holopainen
ABSTRACTWetlands are rich in biodiversity, but globally threatened. After a long period of regional extirpation, beavers have recently returned to many European areas and are now restoring wetlands. The beaver is remarkable regarding the large impacts it has not only on individual species but on entire communities and ecosystems. In fact, beavers are referred to as ‘ecosystem engineers’.The facili... hiện toàn bộ
