Wing base structural data support the sister relationship of megaloptera and neuroptera (insecta: neuropterida). [PDF]

open access: yesPLoS ONE, 2014
The phylogenetic status and the monophyly of the holometabolous insect order Megaloptera has been an often disputed and long unresolved problem. The present study attempts to infer phylogenetic relationships among three orders, Megaloptera, Neuroptera ...

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Molecular phylogeny of Triatomini (Hemiptera: Reduviidae: Triatominae)

open access: yesParasites & Vectors, 2014
Background The Triatomini and Rhodniini (Hemiptera: Reduviidae) tribes include the most diverse Chagas disease vectors; however, the phylogenetic relationships within the tribes remain obscure.

A molecular phylogeny of the Cephinae (Hymenoptera, Cephidae) based on mtDNA COI gene: a test of traditional classification

open access: yesZooKeys, 2011
Cephinae is traditionally divided into three tribes and about 24 genera based on morphology and host utilization. There has been no study testing the monophyly of taxa under a strict phylogenetic criterion.

Are microbes fundamentally different than macroorganisms? Convergence and a possible case for neutral phenotypic evolution in testate amoeba (Amoebozoa: Arcellinida) [PDF]

open access: yesRoyal Society Open Science, 2015
This study reveals extensive phenotypic convergence based on the non-monophyly of genera and morphospecies of testate (shelled) amoebae. Using two independent markers, small subunit ribosomal DNA (ssu-rDNA) and mitochondrial cytochrome oxidase I (COI ...

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa

open access: yesNordic Journal of Botany, EarlyView.
The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.

Delimiting species without nuclear monophyly in Madagascar's mouse lemurs. [PDF]

open access: yesPLoS ONE, 2010
Speciation begins when populations become genetically separated through a substantial reduction in gene flow, and it is at this point that a genetically cohesive set of populations attain the sole property of species: the independent evolution of a ...

Coalescent-based species delimitation in the sand lizards of the Liolaemus wiegmannii complex (Squamata: Liolaemidae) [PDF]

open access: yes, 2019
Coalescent-based algorithms coupled with the access to genome-wide data have become powerful tools forassessing questions on recent or rapid diversification, as well as delineating species boundaries in the absence of reciprocal monophyly.

Lepidagathis konkanensis sp. nov. (Acanthaceae: Barlerieae) from Lateritic Plateaus of Konkan Region of Western Ghats based on morphological and molecular evidence

open access: yesNordic Journal of Botany, EarlyView.
Lepidagathis konkanensis, a new species from the lateritic plateaus of the Konkan region in Maharashtra, India, is described and illustrated based on distinct morphological and molecular characters. Morphologically and phylogenetically, this species is close to L. mahakassapae and L. dalzelliana, but it can be distinguished by its compact inflorescence,
