12 Reported landings of the blue crab (Callinectes sapidus) in the Maryland portion of Chesapeake Bay nearly doubled starting in 1981, coincident with a change from a self-reporting system for harvesters to an interview program with a randomized selection process. A peak in relative abundance as measured by a trapping survey in the Calvert Cliffs region also occurred in 1981 and persisted for s...

A combined proteomics and metabolomics approach was utilised to advance the identification and characterisation of secondary metabolites in Aspergillus fumigatus. Here, implementation of a shotgun proteomic strategy led to the identification of non-redundant mycelial proteins (n = 414) from A. fumigatus including proteins typically under-represented in 2-D proteome maps: proteins with multiple ...

A theoretical framework is proposed to explain how and where complex systems break up into agents or species. Splits lead to diversification and to abundance distributions which are similar to power functions on a rank-abundance representation, and to lognormal functions on a frequency-abundance representation. The combined manifestation of power and lognormal functions is a polo distribution, ...

The decline of sea turtle populations in the Caribbean has led to intensive recovery efforts. In Belizean waters, hawksbill turtles are seemingly making a comeback. At Glover’s Reef Atoll particularly, juvenile hawksbill turtles are found in the fore-reef habitat. The population status and dynamics of this foraging aggregation were assessed to inform conservation management and to ascertain the...

Animal population abundance is a significant parameter for studies on invasive species that can threaten the ecosystem. Researchers have been developing estimation methods since 18th century, in order to evaluate species’ evolution and environmental effects. However, density of Callinectes sapidus are very limited. The present work, using simulation model combined with field measurements, exami...

Aims. The aim of the paper is to understand the emission from the photon dominated regions in Cepheus B, estimate the column densities of neutral carbon in bulk of the gas in Cepheus B and to derive constraints on the factors which determine the abundance of neutral carbon relative to CO. Methods. This paper presents 15×15 fully sampled maps of [C ] at 492 GHz and 12CO 4–3 observed with KOSMA ...

Recent attention has been given to the potential roles that metabolites could play in safety evaluations of new drugs. In 2002, a proposal was published on “metabolites in safety testing” (“MIST”) [T. A. Baillie, M. N. Cayen, H. Fouda, R. J. Gerson, J. D. Green, S. J. Grossman, L. J. Klunk, B. LeBlanc, D. G. Perkins, and L. A. Shipley (2002) Toxicol Appl Pharmacol 182:188–196], which suggested ...

Aquaporin-5 (AQP5) is expressed in epithelia of lung, cornea, and various secretory glands, sites where extracellular osmolality is known to fluctuate. Hypertonic aquaporin (AQP) induction has been described, but little is known about the effects of a hypotonic environment on AQP abundance. We report that, when mouse lung epithelial cells were exposed to hypotonic medium, a dose-responsive decr...

Tropical forests are experiencing large-scale structural changes, the most apparent of which may be the increase in liana (woody vine) abundance and biomass. Lianas permeate most lowland tropical forests, where they can have a huge effect on tree diversity, recruitment, growth and survival, which, in turn, can alter tree community composition, carbon storage and carbon, nutrient and water fluxe...
