An annotated chromosome-level genome for the red-fronted brown lemur ( <i>Eulemur rufifrons</i> ) sheds light on brown lemur evolution Open
The red-fronted brown lemur (Eulemur rufifrons) is an important species to the function of Madagascar's ecosystems, contributing to critical ecological processes such as seed dispersal. Given its ecological, as well as cultural, importance…

Multiple bursts of speciation in Madagascar’s endangered lemurs Open
Lemurs are often cited as an example of adaptive radiation, as more than 100 extant species have evolved and filled ecological niches on Madagascar. However, recent work suggests that lemurs lack a hallmark of other adaptive radiations: ex…

Isolation by environment is more important than isolation by distance along a tropical gradient in direct-developing frogs Open
Abiotic factors are important for defining population structure and limiting gene flow, especially in ectotherm species. In amphibians, abiotic factors like temperature and precipitation can either facilitate or restrict gene flow. The cha…

A Pervasive History of Gene Flow in Madagascar’s True Lemurs (Genus Eulemur) Open
In recent years, it has become widely accepted that interspecific gene flow is common across the Tree of Life. Questions remain about how species boundaries can be maintained in the face of high levels of gene flow and how phylogeneticists…

Multiple bursts of speciation in Madagascar’s endangered lemurs Open
Lemurs are often cited as an example of adaptive radiation. Since colonizing Madagascar, more than 100 extant lemur species have evolved to fill a variety of ecological niches on the island. However, recent work suggests that lemurs do not…

Lemur gut microeukaryotic community variation is not associated with host phylogeny, diet, or habitat Open
Gut prokaryotic (GP) community variation is often associated with host evolutionary and ecological variables; whether these factors drive variation in other gut taxa remains largely untested. We present a one-to-one comparison of GP (16S r…
