#AdaptiveRadiation
What drives speciation in adaptive radiation? And why do patterns emerge? These questions are investigated by Rosemary Gillespie as part of our #AdaptiveRadiation special issue, considering #EcologicalChange and the initial drivers of speciation! 🧪🌍👇

Contrasting patterns of diversity emerge depending on the initial drivers of speciation during adaptive radiation
Abstract. I examine the spatial processes that shape species formation in adaptive radiation, and patterns that emerge from the different processes. I firs

No evidence of transposable element bursts in the Galápagos Scalesia adaptive radiation despite hybridization, diversification and ecological niche shifts - Mobile DNA
Transposable elements (TEs) have been hypothesized to play a pivotal role in driving diversification by facilitating the emergence of novel phenotypes and the accumulation of divergence between specie...

While most #AdaptiveRadiation knowledge is from relatively recent systems, there is increasing evidence for them having a major role in hyperdiverse radiations...such as in Neotropical cichlids! Here, the pharyngeal jaw is studied for signs of just that! 🌍🧪👇🐟

Analysis of the whole pharyngeal jaw adds nuance to the continental radiation of Neotropical cichlids
Abstract. Understanding how continental assemblages have diversified can be difficult as they are products of extinction, biogeographical rearrangements, a

Using 64 populations of Arctic charr in #Scotland, the drivers of its diversity were investigated, finding ecosystem size predicted genetic & phenotypic diversity and highlighting the role of #Ecological opportunity in #AdaptiveRadiation!

Die ersten Naturforscher hatten keinerlei Vorstellung von der großen Formenvielfalt des Lebens auf der Erde. Sie kannten nur die Tiere und Pflanzen ihrer unmittelbaren Umgebung. #Makroevolution #AdaptiveRadiation #Tangaren #Schnabelform #Galápagosinseln
Darwinfinken sind keine Finken: Makroevolution revisited
Der Biologe Guillermo Navalón von der Universität Bristol in England u.a. haben jetzt die Annahmen der ersten Evolutionsbiologen zu Darwinfinken überprüft.

Or think of the Galápagos finches, the ones that inspired Darwin.
Each island’s population evolved beaks fine-tuned to its menu: nuts, cactus seeds, insects.
Natural selection went to work, sculpting variety from a single founding event. 🔍🪶
