The aetiological agent of amphibian chytridiomycosis Batrachochytrium dendrobatidis is a primary cause of amphibian population declines. Current surveillance is based on the detection of B. dendrobatidis in its host but in vitro work suggests infective stages may survive in the abiotic environment for at least 3 mo. We describe here a surveillance system using filtration and quantitative PCR th...

a r t i c l e i n f o Forest-oriented climate mitigation policies promote forestation as a means to increase uptake of atmospheric carbon to counteract global warming. Some have pointed out that a carbon-centric forest policy may be overstated because it discounts biophysical aspects of the influence of forests on climate. In extra-tropical regions, many climate models have shown that forests t...

Forecasting how species and ecosystems will respond to climate change has been a major aim of ecology in recent years. Much of this research has focused on phenology – the timing of life-history events. Phenology has well-demonstrated links to climate, from genetic to landscape scales; yet our ability to explain and predict variation in phenology across species, habitats and time remains poor. ...

Large changes in atmospheric CO2, temperature, and precipitation are predicted by 2100, yet the long-term consequences for carbon (C), water, and nitrogen (N) cycling in forests are poorly understood. We applied the PnET-CN ecosystem model to compare the long-term effects of changing climate and atmospheric CO2 on productivity, evapotranspiration, runoff, and net nitrogen mineralization in curr...

2014 The concept of dwelling is connected with the thermal comfort problem. Radiatively out of balance volumes may agree physiologically and psychologically with the ideal preferred comfort. Nevertheless taking into account vertical and horizontal gradients is a necessity, as well as other parameters of influence like air temperature, air velocity, hygrometry, activity and clothing. The mean ra...

Full retention of sugarcane (interspecifi c hybrids of Saccharum spp.) postharvest residue may reduce ratoon crop yields. The objective of this study was to determine the effects of different residue removal timings and methods on sugarcane yield. A two-factor (timing and method) experiment was conducted on both clay and silt loam soils in southeastern Louisiana. Removal timings consisted of th...
