Our new paper out on # Andean #Biodiversity #hotspots Contrary to classic expectations, we show that young and old #endemicspecies segregate between valleys and elevational zones. First-authored by Jesper Sonne CMEC Science at VILLUM Michael Borregaard royalsocietypublishing.org/doi/abs/10.109…

Today we replaced the offices with a retreat to the fascinating surroundings at #Faxe Limestone Quarry in the search for fossilized crabs, molluscs and the highly sought-after shark teeth 🦈🐚🔍 Thanks to experts Sten Lennart and Christian Mac Ørum for excellent guidance!

NEW EXPEDITION to #Ecuador from the Villum Center for Global Mountain Biodiversity aims at enhancing our understanding of the processes building #biodiversity hotspots in tropical mountains via satellite data & genetic bird data 🏔🐦 Find out more 👇 macroecology.ku.dk/news_and_media…

About to return from a month long expedition to Ecuador studying birds in the high Andean Polylepis forests. Those are magical places although very tough to work in. Many of the birds survive with super small population sizes. CMEC Carsten Rahbek Science at VILLUM

One of the expedition’s target species: Violet-throated metaltail, which is a super range-restricted hummingbird from Southern Ecuador. We use population genetic tools to study the population’s historical dynamics Science at VILLUM CMEC

Target species #2 Blue-mantled Thornbill. They are often seen walking on the ground to preserve energy in the thin mountain air. Our project investigates the rare dispersal events that ought to maintain connectivity between isolated habitats CMEC Science at VILLUM

Target species #3 Giant Conebill – Polylepis forest spacialist. We found them persistently in the forest patches but in super low densities. In the project, we hope to get new insight into such species’ population structure and dispersal dynamics. CMEC Science at VILLUM

Target species #4 Tit-like Dacnis - a habitat specialist found in Gynoxis shrub, which commonly grows in Polylepis forests. Our expedition brought new genetic material from the Ecuadorian population. CMEC Science at VILLUM

Excited to participate in a summer project aiming at counting and mapping all breeding birds at Skuvoy - a small Faroese island. having bird census data dating back to the sixties, the island is an excellent model system to monitor long-term population dynamics. CMEC

Skuvoy used to have the largest Guillemot colonies in the North Atlantic. They have declined substantially over the last 50 years, and counting them today is a depressing exercise. Observing the colonies from land gives an idea of how difficult the birds are to count from the sea

Getting closer to solving #Humboldt' Enigma - or why some mountain regions is the hottest of the hottest biodiversity hotspots in the world. We have a new paper out in PNAS PNASNews J. Sonne, C. Rahbek, Idiosyncratic patterns of local species richness and turnover define
