Catching crabs: a case study in local-scale English conservation [PDF]
arXiv, 2014 Wells-next-the-Sea and Cromer in Norfolk (England) both rely upon their local crab populations, since crabbing (gillying) is a major part of their tourist industry. Compared to a control site with no crabbing, crabs from Wells harbour and Cromer pier were found to have nearly six times the amount of limb damage.

Ecography, EarlyView.Community ecology has been described as a ‘mess' because ecological processes vary in space, time, and across species traits, resulting in myriads of ecological contingencies and low scientific predictability. Here, we aimed to identify and rank ecological contingencies and improve predictability using fully crossed high‐order factorial mensurative and

Robust Soldier Crab Ball Gate [PDF]
Complex Systems 20 (2011) 2, 2012 Soldier crabs Mictyris guinotae exhibit pronounced swarming behaviour. The swarms of the crabs tolerant of perturbations. In computer models and laboratory experiments we demonstrate that swarms of soldier crabs can implement logical gates when placed in a geometrically constrained environment.

Crab: the standard X-ray candle with all (modern) X-ray satellites [PDF]
, 2005 Various X-ray satellites have used the Crab as a standard candle to perform their calibrations in the past. The calibration of XMM-Newton, however, is independent of the Crab nebula, because this object has not been used to adjust spectral calibration issues. In 2004 a number of special observations were performed to measure the spectral parameters and

Trophic ecology of groundfishes in nearshore areas of the Gulf of Maine
Journal of Fish Biology, EarlyView.Abstract Ecosystem management requires an integrated understanding of ecological interactions. In the Gulf of Maine (GoM), trophic information pertaining to commercially important groundfishes and nearshore prey communities is lacking. We characterized nearshore communities and groundfish diets using data collected from nearshore surveys (864 bottom ...

High-flux water desalination with interfacial salt sieving effect in nanoporous carbon composite membranes [PDF]
arXiv, 2016 Nanoporous carbon composite membranes, comprising a layer of porous carbon fiber structures with an average channel width of 30-60 nm grown on a porous ceramic substrate, are found to exhibit robust desalination effect with high freshwater flux. In three different membrane processes of vacuum membrane distillation, reverse osmosis and forward osmosis ...
