Project Background

Invertebrates make up the vast majority of animals on the planet, however the amount of research that has been carried out on this incredibly diverse group of is disproportionately small compared to that undertaken on vertebrates. Similarly, the work on seasonality in tropical environments has been small primarily as there was a belief that tropical animals did not show seasonality. However this is not the case and mechanisms such as humidity and rainfall have been shown to initiate and terminate seasons in tropical invertebrates.

Projects exist to investigate the occurrence and the factors affecting seasonality in tropical invertebrates (both terrestrial and aquatic) and how these mould the ecology of these species.

Project Updates

Invertebrates possess no backbone, but punch above their weight in terms of diversity and abundance on earth. How are tropical invertebrates affected by seasons?
