Phylogenomics Reveals the Evolutionary History of Phytolacca (Phytolaccaceae)

open access: yesFrontiers in Plant Science, 2022
Phytolacca is the largest genus of Phytolaccaceae. Owing to interspecific hybridization, infraspecific variation, and apparent weak genetic control of many qualitative characters, which have obscured boundaries between species, the classification and ...

COMPARATIVE ANALYSIS OF THE COMPOSITION OF THE TERRESTRIAL FAUNA AND FLORA OF THE TETHYS DESERT-STEPPE REGION OF PALEARARTICS, BIOGEOGRAPHIC BOUNDARIES OF THE CAUCASUS. MESSAGE 3. MAIN POINTS OF FORMATION OF THE BIOTA OF THE CAUCASUS

open access: yesЮг России: экология, развитие, 2017
Aim. The aim is to analyze the main points of the formation of the biota of the Caucasus.Results. Discussed points: the boundaries of the Tethys desert-steppe belt of the Palaearctic and the place of the Caucasus in it, as well as the role of marine ...

RADseq analyses reveal concordant Indian Ocean biogeographic and phylogeographic boundaries in the reef fish Dascyllus trimaculatus [PDF]

open access: yesRoyal Society Open Science, 2019
Population genetic analysis is an important tool for estimating the degree of evolutionary connectivity in marine organisms. Here, we investigate the population structure of the three-spot damselfish Dascyllus trimaculatus in the Red Sea, Arabian Sea and

Modelling the biogeographic boundary shift of Calanus finmarchicus reveals drivers of Arctic Atlantification by subarctic zooplankton [PDF]

open access: yesGlobal Change Biology, 2021
AbstractBiological communities in the Arctic are changing through the climate‐driven encroachment of subarctic species. This “Atlantification” extends to keystone Calanoid copepods, as the small‐bodied Calanus finmarchicus increases in abundance in areas where it overlaps with larger Arctic congeners.

Spatial analyses of benthic habitats to define coral reef ecosystem regions and potential biogeographic boundaries along a latitudinal gradient. [PDF]

open access: yesPLoS ONE, 2012
Marine organism diversity typically attenuates latitudinally from tropical to colder climate regimes. Since the distribution of many marine species relates to certain habitats and depth regimes, mapping data provide valuable information in the absence of

Comparative Phylogeography of Southern African Bird Species Suggests an Ephemeral Speciation Model

open access: yesDiversity, 2021
Southern Africa is remarkably rich in avian species diversity; however, the evolutionary and biogeographic mechanisms responsible for that diversity are, in general, poorly understood, and this is particularly true with respect to the many species that ...

Climate change alters the future of natural floristic regions of deep evolutionary origins

open access: yesNature Communications
Biogeographic regions reflect the organization of biotas over long evolutionary timescales but face alterations from recent anthropogenic climate change.

Zoning of waters in the Australian-New Zealand sector of the South Ocean by the example of distribution of pelagic ostracods from subclass Myodocopa

open access: yesИзвестия ТИНРО, 2015
Distribution of mass antarctic, subantarctic, antarctic-subantarctic and tropical-subtropical interzonal pelagic ostracods is considered depending on structure and dynamics of waters in the Australian-New Zealand sector of the South Ocean on the base of ...

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 ...

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.
