Model biases in rice phenology under warmer climates
Climate-induced crop yields model projections are constrained by the accuracy of the phenology simulation in crop models. Here, we use phenology observations from 775 trials with 19 rice cultivars in 5 Asian countries to compare the performance of four rice phenology models (growing-degree-day (GDD), exponential, beta and bilinear models) when applied to warmer climates. For a given cultivar, t...
متن کاملWarmer climate squeezes aquatic predators out of their preferred habitat.
Ecosystems are mosaics of different habitats, each of which provides its own opportunities and risks to the organisms that inhabit it. The profitability of any habitat depends on a variety of biotic and abiotic variables including the abundance of prey, vulnerability to predators, and physical features such as temperature that modify physiology and behavior. Because biological and physical cond...
متن کاملUnearthing the secrets of ancient immature insects
Jurassic fossils of a bizarre fly larva that lived in water as a blood-sucking parasite highlight how much can be learnt from the study of the fossils of immature insects.
متن کاملReproductive Trade-Offs May Moderate the Impact of Gyrodactylus salaris in Warmer Climates
Gyrodactylus salaris is a notifiable freshwater ectoparasite of salmonids. Its primary host is Atlantic salmon (Salmo salar), upon which infections can cause death, and have led to massive declines in salmon numbers in Norway, where the parasite is widespread. Different strains of S. salar vary in their susceptibility, with Atlantic strains (such as those found in Norway) exhibiting no resistan...
متن کاملDo Oaks With a Provenance Related to Warmer Climates Emit More Isoprene?
The hydrocarbon isoprene plays an important role in atmospheric chemistry, particularly in regards to air pollution and climate change. It is important to know why certain plant species emit isoprene and what factors affect its production in order to predict future air quality. Past research has indicated that isoprene aids in coping with heat stress, so it was hypothesized that source latitude...
