Coastal fisheries and mollusk and seaweed culture in Southeast Asia: Integrated planning and precautions [PDF]

, 1995
Capture fisheries in Southeast Asia are characterized by rampant overfishing, made worse in many areas by problems of overpopulation and by inappropriate management strategies based on misconceptions about tropical fisheries.

Phylogenomic analysis of ultraconserved elements clarifies relationships and morphological evolution in Cryptoplacoidea (Mollusca: Polyplacophora)

Cladistics, EarlyView.
Abstract Targeted enrichment of ultraconserved elements (UCEs) is a powerful tool for resolving phylogeny in groups with limited morphological or molecular data. Here, we use UCEs to reconstruct the first comprehensive phylogeny of the chiton superfamily Cryptoplacoidea, including museum material up to 133 years old.

The distribution of chitin in larval shells of the bivalve mollusk Mytilus galloprovincialis

, 2006
The insoluble matrix of larval shells of the marine bivalve mollusk Mytilus galloprovincialis is investigated by confocal laser scanning microscopy using a GFP fusion protein with a chitin-binding domain for labeling of chitinous structures. We show that

Population structure of the bivalve Anomalocardia brasiliana, (Gmelin, 1791) in the semi-arid estuarine region of northeastern Brazil

Brazilian Journal of Biology
For several decades, the bivalve mollusk Anomalocardia brasiliana has been extracted in estuarine areas in the semi-arid region of northeastern Brazil. However, information on both dynamics and abundance of their populations are missing. In this context,

Extreme site fidelity in long‐distance migratory shorebirds in Australia and potential implications for conservation

Conservation Biology, EarlyView.
Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...

Phylogenetic support values are not necessarily informative : the case of the Serialia hypothesis (a mollusk phylogeny) [PDF]

, 2009
Background: Molecular phylogenies are being published increasingly and many biologists rely on the most recent topologies. However, different phylogenetic trees often contain conflicting results and contradict significant background data. Not knowing how

Effects of different hydrological conditions on the taxonomic structure and functional traits of mollusk communities in a large floodplain wetland

Ecology and Evolution
Floodplain wetlands are critical to the conservation of aquatic biodiversity and the ecological integrity of river networks. However, increasing drought severity and frequency caused by climate change can reduce floodplain wetlands' resistance and ...

Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary

Journal of Fish Biology, EarlyView.
Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

Comparative taphonomy and faunal composition of shelly cheniers from northeastern Baja California, Mexico

Ciencias Marinas, 1995
This report presents the results of comparative taphonomic and faunal analyses of shelly cheniers (mollusk-dominated lag concentrations) from the tidal flats of northeastem Baja California, Mexico. Three generations of cheniers that differ in age and in
