ECR Feature: Nicky Lustenhouwer on niche shifts in invasive plants

Nicky Lustenhouwer is a postdoc at the University of Aberdeen. She is an evolutionary ecologist interested in range expansions and invasive organisms. Nicky shares her recent work on the relative roles of climate change tracking versus niche evolution in the spread of an invasive weed. Nicky Lustenhouwer with a particularly large individual of Dittrichia graveolensContinue reading “ECR Feature: Nicky Lustenhouwer on niche shifts in invasive plants”

Evolution of solitary bees suggests a biogeographic history connecting open habitats in South and North America

More than 1,000 species of eucerine bees exist mainly in savannas, deserts, and other open vegetation habitats on multiple continents, but they are uncommon near the equator and very high latitudes. The historical processes that generated this modern pattern for Eucerinae (and other taxa) are still surrounded by uncertainties. Above: Representatives of each one ofContinue reading “Evolution of solitary bees suggests a biogeographic history connecting open habitats in South and North America”

Diversity of the Deep

Previous work has characterized diversity gradients in terrestrial and shallow-water system. Are these previously described diversity gradients also applicable to hard-substrate features in the deep sea? Above: Some example seabed images from the cruises around St Helena, Ascension and Tristan da Cunha (Credit: British Antarctic Survey/Centre for Environment, Fisheries and Aquaculture Science). Investigation into theContinue reading “Diversity of the Deep”

Flowers, biomes, and a mountain of data

Describing patterns of flowering time in plant communities across six biomes, and showing how they relate to climate means and climate predictability – all using open access data and a reproducible analysis in R. Above: Bossiaea foliosa (Leafy Bossiaea) flowering in the Snowy Mountains in southeast Australia. Alpine flowering is often highly concentrated, as everythingContinue reading “Flowers, biomes, and a mountain of data”

The Paleotropical Biome Rode the Ark of the Indian Plate from Africa to Asia

Tropical biomes today occupy a disjunct distribution around the equator covering about 7% of land surface, but harbouring more than 40% of plant species. This mystery is a fascinating topic yet to be fully addressed. We attempt to solve this mystery using our knowledge on the origin and migration of tropical gingers across these globalContinue reading “The Paleotropical Biome Rode the Ark of the Indian Plate from Africa to Asia”
