1. Breeding effort and hydroperiod indicate habitat quality of small, isolated wetlands for amphibians under climate extremes.

The distribution and function of small, temporarily ponded wetlands such as vernal pools are driven by climate variation, especially precipitation. These wetland ecosystems provide important habitat for amphibians, whose breeding effort (egg deposition) is often used to characterize pool habitat...

3. The larval haematopoietic organs of Manduca sexta (Insecta, Lepidoptera): an insight into plasmatocyte development and larval haematopoiesis.

Haematopoietic organs (HOs) in Lepidoptera are widely recognised as the source for at least two haemocyte types. With new specific markers for oenocytoids and spherule cells and a method to identify prohaemocytes, the haemocytes formed in and released by the HOs of Manduca sexta are characterised....

4. Fitness cost of imidacloprid resistance in the cotton-staining bug, Dysdercus koenigii.

Dysdercus koenigii, a serious cotton-staining insect pest in many countries, has shown high resistance to imidacloprid, a systemic neonicotinoid insecticide used to control sap-sucking pests. With the aim of creating an effective management strategy, the biological traits of susceptible (SS) and...

Northern gannets (Morus bassanus) have been ranked as one of the most vulnerable species in terms of collision with offshore wind farm (OWF) turbines, and strong avoidance of OWFs has been documented for this species. Gannets increasingly encounter OWFs within the ranges of their largest breeding...
