Modelling dispersal of a temperate insect in a changing climate
We construct a novel individual-based random-walk model to assess how predicted global climate change might affect the dispersal rates of a temperate insect. Using a novel approach we obtained accurate field measurements of daily movements for individuals over time to parameterize our model. Males were found to move significantly further on average than females. Significant variation in movement w
The temperature-size rule in ectotherms : May a general explanation exist after all?
The majority of ectotherms mature at a larger size at lower rearing temperatures. Although this temperature-size rule is well established, a general explanation for this phenomenon has remained elusive. In this article, we address the problem by exploring the proximate and ultimate reasons for why a temperate grasshopper, Chorthippus brunneus, is an exception to the temperature-size rule. Using a
What keeps insects small? Time limitation during oviposition reduces the fecundity benefit of female size in a butterfly
Laboratory studies of insects suggest that female fecundity may increase very rapidly with adult size and that mass may often increase close to exponentially with time during larval growth. These relationships make it difficult to see how realistic levels of larval mortality can outweigh the fecundity benefit of prolonged growth. Hence, it is unclear why many insects do not become bigger. In this

CGRP and its receptors provide new insights into migraine pathophysiology
Over the past 300 years, the migraine field has been dominated by two main theories-the vascular theory and the central neuronal theory. The success of vasoconstrictors such as ergotamine and the triptans in treating acute migraine bolstered the vascular theory, but evidence is now emerging that vasodilatation is neither necessary nor sufficient to induce a migraine attack. Attention is now turnin
Cryogel-supported titanate nanotubes for waste treatment: Impact on methane production and bio-fertilizer quality.
By reducing the cadmium (Cd(2+)) content in biomass used for bio-based products such as biogas, a less toxic bio-based fertilizer can be obtained. In this work, we demonstrate how a macroporous polymer can support titanate nanotubes, and we take advantage of its known selective adsorption behavior towards Cd(2+) in an adsorption process from real nutrient-rich process water from hydrolysis of seaw
Warming-induced increase in aerosol number concentration likely to moderate climate change
Atmospheric aerosol particles influence the climate system directly by scattering and absorbing solar radiation, and indirectly by acting as cloud condensation nuclei(1-4). Apart from black carbon aerosol, aerosols cause a negative radiative forcing at the top of the atmosphere and substantially mitigate the warming caused by greenhouse gases(1). In the future, tightening of controls on anthropoge
