Wing Shape in the Taxonomic Identification of Genera and Species of the Subfamily Dolichopodinae (Dolichopodidae, Diptera) [PDF]

open access: yesMongolian Journal of Biological Sciences, 2019
Characters of the wing morphology have significant importance in the systematics and taxonomy of the family Dolichopodidae, but there are only a few studies concerning the variation in wing shape of dolichopodid flies.

Lujiatun Psittacosaurids: understanding individual and taphonomic variation using 3D geometric morphometrics. [PDF]

open access: yesPLoS ONE, 2013
Psittacosaurus is one of the most abundant and speciose genera in the Dinosauria, with fifteen named species. The genus is geographically and temporally widespread with large sample sizes of several of the nominal species allowing detailed analysis of ...

Inter‐ and intraspecific variation in mycotoxin tolerance: A study of four Drosophila species

open access: yesEcology and Evolution, 2022
Many mycophagous Drosophila species have adapted to tolerate high concentrations of mycotoxins, an ability not reported in any other eukaryotes. Although an association between mycophagy and mycotoxin tolerance has been established in many Drosophila ...

Interspecific Hybridization between Cucurbita Maxima Duch. and Cucurbita Moschata Duch. for High Efficient Development of Cucurbit Rootstocks [PDF]

open access: yesJournal of Plant Production, 2017
Interspecific hybrids between Cucurbita maxima and C. moschata have been commonly used as a rootstock for watermelon, melon, and cucumber, as well as to develop new Cucurbit types and widen the genetic variation.

Size dimorphism and directional selection in forest millipedes [PDF]

open access: yesArthropods, 2019
Sexual Size Dimorphism (SSD) in the diplopod genus Centrobolus has a positive correlation with body size. Length, width and rings are the main components of interspecific variation in diplopod species.

Trait-Based Community Assembly along an Elevational Gradient in Subalpine Forests: Quantifying the Roles of Environmental Factors in Inter- and Intraspecific Variability.

open access: yesPLoS ONE, 2016
Understanding how communities respond to environmental variation is a central goal in ecology. Plant communities respond to environmental gradients via intraspecific and/or interspecific variation in plant functional traits.

Intra- and inter-isolate variation of ribosomal and protein-coding genes in Pleurotus: implications for molecular identification and phylogeny on fungal groups

open access: yesBMC Microbiology, 2017
Background The internal transcribed spacer (ITS), RNA polymerase II second largest subunit (RPB2), and elongation factor 1-alpha (EF1α) are often used in fungal taxonomy and phylogenetic analysis.

Differences in wings may be sufficient to separate the sexes and two species of Gynaikothrips Zimmermann (Thysanoptera: Phlaeothripidae)?

open access: yesEntomoBrasilis, 2022
In this study, we use geometric morphometry to discriminate thrips of the species Gynaikothrips uzeli (Zimmerman) and Gynaikothrips ficorum (Marchal) and also to detect sexual dimorphism in these species. Two hundred individuals, one hundred females and

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.
