A synthetic phylogeny of freshwater crayfish: insights for conservation [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2015
Phylogenetic systematics is heading for a renaissance where we shift from considering our phylogenetic estimates as a static image in a published paper and taxonomies as a hardcopy checklist to treating both the phylogenetic estimate and dynamic taxonomies as metadata for further analyses. The Open Tree of Life project (

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Baseline study on the fish and freshwater crayfish fauna in the Blackwood River and its tributaries receiving discharge from the Yarragadee Aquifer [PDF]

, 2005
Water from the Yarragadee Aquifer surfaces in Poison Gully and Milyeannup Brook, and maintains flow in these Blackwood River tributaries throughout the year. It also enters Layman Brook during winter and spring, yet this stream dries during summer.

Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

Journal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Introduction of redclaw crayfish Cherax quadricarinatus (von Martens) to Lake Kununurra, Ord River, Western Australia: Prospects for a 'yabby' in the Kimberley [PDF]

, 2004
The recent introduction of redclaw crayfish for aquaculture to the Ord River region of Western Australia has been followed by the detection of a ‘wild’ population in Lake Kununurra. A gut survey of the lake’s fish fauna was used to estimate the degree of

A CRISPR‐Based Rapid Detection Assay for Crayfish Plague (Aphanomyces astaci) From Environmental Samples

Journal of Fish Diseases, EarlyView.
ABSTRACT Crayfish plague, caused by Aphanomyces astaci (Aa), is an infectious disease invasive in Europe, where its rapid spread has resulted in sharp declines of native crayfish species. Monitoring currently relies on a highly sensitive, but costly and time‐consuming qPCR approach.

Survival, Growth, and Reproduction: Comparison of Marbled Crayfish with Four Prominent Crayfish Invaders

Biology, 2021
Biological invasions are increasingly recognized ecological and economic threats to biodiversity and are projected to increase in the future. Introduced freshwater crayfish in particular are protruding invaders, exerting tremendous impacts on native ...
