Miniaturised frogs form a fascinating but poorly understood amphibian ecomorph and have been exceptionally prone to taxonomic underestimation. The subfamily Cophylinae (family Microhylidae), endemic Madagascar, has particularly large diversity of miniaturised species which historically attributed the single genus Stumpffia largely based on their small size. Recent phylogenetic work revealed that several independent lineages cophyline microhylids evolved towards highly body sizes, achieving...

This paper develops an account of pluralities based on the following simple claim: some things are nothing over and above individual they comprise. For some, this may seem like a mysterious statement, perhaps even meaningless; for others, truism, trivial inferentially inert. I show that neither reaction is correct: claim both tractable has important consequences number debates in philosophy.

Abstract Objectives The investigation of morphological variation in animals is widely used taxonomy, ecology, and evolution. Using large datasets for meta‐analyses has dramatically increased, raising concerns about dataset compatibilities biases introduced by contributions multiple researchers. Materials Methods We compiled data on 13 variables 3073 individual mouse lemurs (Cheirogaleidae, Microcebus spp.) from 25 taxa 153 different sampling locations, measured 48 applied a filtering...

The systematics of the cophyline microhylid frog genera Plethodontohyla and Rhombophryne have long been intertwined, their relationships only recently started to become clear. While has received a lot recent taxonomic attention, largely neglected. Our study is showcase just how complex situation between these two is, care that must be taken resolve conundrums where old material, multiple genus transitions, misattribution new material obfuscate picture. We assessed identity historic names...

The Critically Endangered day gecko Phelsuma antanosy is micro-endemic to 2 humid forest sites in southeastern Madagascar. At one of these, Sainte Luce, it inhabits 4 fragments, which are set be cleared for mining. Translocation individuals from within the mining path protected fragments has been proposed mitigate impact habitat loss and resulting reduction population size. However, lack knowledge its requirements structure inhibits efforts evaluate likely ecological consequences...

The concept of “facilitated restoration” aims at native biodiversity reinstatement with the help animal seed dispersers attracted by fruiting trees. Yet, large-crowned trees will have to develop in early stages restoration; therefore, dispersal provided small generalist mammals and birds that use rapidly growing herbs, shrubs, forest succession would accelerate restoration. Due elusive lifestyle these animals, it is unclear what species can contribute this process. Using primate genus...

Most of the unique and diverse vertebrate fauna that inhabits Madagascar derives from in situ diversification colonisers reached this continental island through overseas dispersal. The endemic Malagasy Scincinae lizards are amongst most species-rich squamate groups on island. They colonised all bioclimatic zones display many ecomorphological adaptations to a fossorial (burrowing) lifestyle. Here we propose new phylogenetic hypothesis for their based largest taxon sampling so far compiled...
