Island theory is still relevant to alpine biogeography
Area, environmental heterogeneity, scale and the conservation of alpine diversity. Above: Phyteuma hemisphericum from the Sierra de Villabandín, Cantabrian Mountains, Spain; photograph by Borja Jiménez-Alfaro This project was an extension of our work on the relative importance of geographic distance and environmental difference to the beta diversity of alpine plant communities (Malanson et al. 2022).Continue reading “Island theory is still relevant to alpine biogeography”
Elucidating river history through population genetics of an aquatic organism
Rivers sometimes change their way, caused by geological events. During such river rearrangement, what happened to the inhabitants? We investigated the genetic traces remaining in genomes of the descendants and look for a way to find unidentified geological events. Above: An upper reach of mountain stream on Honshu Island, Japan. Honshu Island, the main islandContinue reading “Elucidating river history through population genetics of an aquatic organism”

Explaining global body size variation in dragonflies and damselflies: temperature or predators?
Global body size distributions in dragonflies and damselflies are shaped by temperature and predators Above: A model replica of a fossil dragonfly (Urogomphus giganteus) in Museum für Naturkunde (Berlin) that lived about 140 million years ago. Dragonflies and damselflies have an unusually rich fossil record, compared to other insect groups. Photo: Erik Svensson. Dragonflies andContinue reading “Explaining global body size variation in dragonflies and damselflies: temperature or predators?”

Poor flyers in the sky (-islands)
“As with mariners shipwrecked near a coast, it would have been better for the good swimmers if they had been able to swim still further, whereas it would have been better for the bad swimmers if they had not been able to swim at all and had stuck to the wreck.” (Darwin 1859) Above: ChorthippusContinue reading “Poor flyers in the sky (-islands)”
Vegetation on Mt. Teide (Tenerife) during Humboldt’s time and now
Using historical records to reconstruct how species presence/absence and altitudinal ranges have changed between 1815 and today. Above: The northern slope of Tenerife island, with the Orotava valley, The sea of clouds and the Teide peak (3718 m,) climbed by Humboldt & Bonpland (1799) and von Buch & Smith climbed (1815) (Photo: José María Fernández-Palacios).Continue reading “Vegetation on Mt.

ECR feature: Jeff Stallman on mushrooms and the theory of island biogeography
Jeff Stallman is a PhD candidate at the Purdue University. He is particularly interested in the taxonomy, systematics, and biogeography of macro-fungi, with an emphasis on the Hawaiian Islands. Here, Jeff shares his recent work on mushrooms endemic to oceanic islands and how they fit in with the theory of island biogeography. On a collectingContinue reading “ECR feature: Jeff Stallman on mushrooms and the theory of island biogeography”
