Son, Anna-Sofie Stensgaard, Ben Collen
With the biodiversity crisis continuing unchecked, we need to establish levels and drivers of extinction risk, and reassessments over time, to effectively allocate conservation resources and track progress towards global conservation targets. Given that threat appears particularly high in freshwaters, we assessed the extinction risk of 1428 randomly selected freshwater molluscs using the IUCN Red ...... hiện toàn bộ

Life cycle of Calanus chilensis Brodsky in Bay of San Jorge, Antofagasta, Chile
Hydrobiologia - Tập 292 - Trang 289-294 - 1994
Ruben Escribano, Luis Rodriguez
The copepod Calanus chilensis is an endemic component of the zooplankton community in northern Chile. Size distributions of adult females, relative frequency of copepodid stages and relative numbers of adult males and nauplii, suggest the presence of at least 6 generations during the year, although the species seems to continuously reproduce through all seasons. Temperature profiles from 0 to 175 ...... hiện toàn bộ
Pink eggs and snails: field oviposition patterns of an invasive snail, Pomacea insularum, indicate a preference for an invasive macrophyte
Hydrobiologia - Tập 646 - Trang 243-251 - 2010
Romi L. Burks, Colin H. Kyle, Matthew K. Trawick
Oviposition of non-calcareous or thinly shelled eggs represents an important life stage of many insects, amphibians, and several gastropods. A recently identified invasive species of apple snail, Pomacea insularum, exhibits alarming invasive characteristics of high reproductive rates and generalist consumption patterns. This snail takes the opposite approach to egg laying compared to most aquatic ...... hiện toàn bộ
A new annelidicolous copepod, Cyclorhiza megalova n. sp., with comments on its functional biology and possible phylogenetic relationships
Hydrobiologia - Tập 167 - Trang 533-538 - 1988
R. V. Gotto, Yvonne Leahy
A new copepod belonging to the little-known family Phyllodicolidae has been found in Galway Bay, western Ireland, infesting the phyllodocid polychaet Eteone longa. It is a strongly transformed species showing marked extra-ecdysial growth and possessing some interesting adaptive features. A description is presented, along with some notes on its functional biology and an assessment of its possible p...... hiện toàn bộ

Diversity of bacterial communities in Adirondack lakes: do species assemblages reflect lake water chemistry?
Hydrobiologia - Tập 401 - Trang 77-96 - 1999
B. A. Methé, J. P. Zehr
Bacterial diversity was examined in six lakes located in the Adirondack Mountains of upstate New York. This region receives significant anthropogenic atmospheric inputs of strong mineral acids resulting in decreases in pH and acid neutralizing capacity (ANC) in many of the lakes. Statistical methods including correlation and cluster analysis were used to determine if there were significant associa...... hiện toàn bộ
Aquatic invertebrate assemblages during the spring-thaw season in wetlands of Northeastern China
Hydrobiologia - Tập 848 - Trang 3943-3953 - 2021
Kangle Lu, Darold P. Batzer, Haitao Wu
Identifying the character and importance of invertebrates in thawing wetlands is useful, since they are the main food resource for migratory waterfowl during spring. We investigated aquatic invertebrate composition in the spring-thaw and compared it with the summer in wetlands of the Sanjiang Plain, China. NMDS analysis showed that the composition of aquatic invertebrates in the spring-thaw is sig...... hiện toàn bộ
Use of an extensive radio receiver network to document Pacific lamprey (Lampetra tridentata) entrance efficiency at fishways in the Lower Columbia River, USA
Hydrobiologia - Tập 483 - Trang 45-53 - 2002
Mary L. Moser, Alicia L. Matter, Lowell C. Stuehrenberg, Ted C. Bjornn
We used an extensive network of more than 170 radio receiving stations to document fine-scale passage efficiency of adult anadromous Pacific lamprey at Bonneville and The Dalles Dams in the lower Columbia River in the northwestern U.S.A. Each spring from 1997 to 2000, we released 197–299 lamprey with surgically implanted radio transmitters. Unique transmitter codes and the date and time of recepti...... hiện toàn bộ
