Variability and Taxonomic Status of Siberian Population of Alpine Sculpin Cottus poecilopus Complex (Scorpaeniformes: Cottidae) [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2013
The main goal of investigation is the analysis of ecological and geographical variability of morphological characters of alpine sculpin Cottus poecilopus complex in the Siberian rivers – Lena, Ob, Amur for identification of their taxonomic status.

A Conserved DT2‐bZIP66‐NF‐YC4 Regulatory Module Confers Drought Tolerance in Rice and Arabidopsis

open access: yesAdvanced Science, EarlyView.
This study identifies a conserved tripartiteDT2–bZIP66–NF‐YC4 transcriptional module that enhances rice drought tolerance by activating stress‐responsive genes. This regulatory complex is functionally conserved across cereals and Arabidopsis, providing promising targets for engineering drought‐resilient crops. ABSTRACT Drought stress severely restricts

Phylogeography of Dolichophis Populations in the Aegean Region (Squamata: Colubridae) with Taxonomic Remarks

open access: yesDiversity
In this study, we investigate the phylogeographic patterns of Dolichophis species in the Aegean region, aiming to elucidate their genetic diversity and putative historical colonisation routes through mitochondrial and nuclear DNA data.

A case of budding speciation in the California Floristic Province and infraspecific divergence in Abronia villosa

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Budding speciation occurs when peripheral populations adapt to local ecological conditions and “bud” off from a widespread progenitor species. Traditionally regarded as rare because of its sympatric and parapatric nature, budding speciation is largely understudied.

Historical ostriches in the Libyan Desert, with ecological and taxonomic considerations

open access: yesNatural History Sciences
Many historical records extend the known range of the African ostrich Struthio camelus to include almost the entire state territory of Libya. This significant expansion augments the spatial potentialities to reintroduce captive-bred progeny of the ...

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

open access: yesThe Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Notes on the Strumariinae (Amaryllidaceae-Amaryllideae). Six new taxa in Strumaria and Hessea from the central and northwestern Cape, South Africa, and southern Namibia

open access: yesBothalia: African Biodiversity & Conservation, 1992
Newly described are four species and a subspecies of Strumaria and one species of Hessea. S.  aestivalis  Snijman from the Langberg and  S. perryae Snijman from the Bokkeveld escarpment are rare species closely allied to S. pubescens W.F. Barker.
