Effect of salinity stress on the life history variables of Branchipus schaefferi Fisher, 1834 (Crustacea: Anostraca) [PDF]

, 2005
BACKGROUND: Freshwater anostracans inhabit ephemeral water bodies in which as the water level decreases due to evaporation the salt concentration increases. Thus, for most anostracans salinity becomes the major stress factor.

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

A checklist of benthic macroinvertebrates of River Manuni, Himachal Pradesh

Environment Conservation Journal, 2011
Himachal Pradesh is drained by five main rivers and their tributaries. River Manuni originates from the southern slopes of the Dhauladhar range and joins River Baner on the rear side of the Kangra fort to finally meet the River Beas near Haripur in ...

Experimental confirmation of protandric simultaneous hermaphroditism in a Caridean shrimp outside of the genus Lysmata [PDF]

, 2008
Caridean shrimps display a variety of sexual systems including gonochorism and various forms of protandry but rarely simultaneous hermaphroditism. Protandric simultaneous hermaphroditism (PSH) has thus far only been demonstrated in the genus Lysmata. The

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Molecular identification of chitinase and its function in growth of Odontobutis potamophila

Aquaculture Reports
Chitinases are pivotal enzymes for the degradation of chitin, which play a role in food digestion. However, the functional roles of chitinases in teleosts remain under-explored.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

RECORD OF METACERCARIAE OF PARAGONIMUS BRAUN, 1899 (PLATYHELMINTHES: TREMATODA) IN THE AMAZON PROVINCE: THE SECOND ALERT OF TREMATODES AS POTENTIAL RISK TO HUMAN HEALTH IN THE STATE OF PARÁ, BRAZIL

Environmental Smoke
In this study we report a new occurrence of Paragonimus Braun, 1899 in the Amazon province, recovered from a new host, the semi-terrestrial sesarmid crab Armases benedicti (Rathbun, 1897).

Sustainable recovery of a chitin–glucan complex–protein biocomposite from yeast biomass using biocompatible ionic liquids

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Chitin–glucan complex (CGC) is typically extracted from fungal or yeast biomass using harsh alkaline treatments that not only generate high‐salt, organic‐rich effluents, but also negatively impact the structural and functional properties of the recovered copolymer, while wasting the yeast protein fraction, which is discarded.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis
