Vicariance and dispersal in the Aegean Archipelago: Molecular phylogeography reveals the origin and divergence times of Hydropsyche (Trichoptera: Hydropsychidae) species

Journal of Systematics and Evolution, EarlyView.
Divergence times of Greek Hydropsyche lineages fall mostly within the Pliocene‐Pleistocene, rejecting ancient vicariance. Widespread species show shallow divergences consistent with dispersal, while island endemics exhibit deeper isolation patterns supporting a mixed vicariance‐dispersal model.

Early hominin speciation at the Plio/Pleistocene transition

HOMO, 2003
Over the last half-decade or so, there has been an explosion in the recognition of hominin genera and species. We now have the late Miocene genera Orrorin and Sahelanthropus, the mid Pliocene genus Kenyanthropus, three new Pliocene species of Australopithecus (A. anamensis, A. garhi and A. bahrelghazali) and a sub species of Ardipithecus (Ar.

Small Mammals in the Plio/Pleistocene Sediments of Greece

, 2016
Small mammals represent an important source of biostratigraphic and ecological information at Plio/Pleistocene localities. In this paper, we provide an overview of small mammals from Pliocene and Pleistocene sites in Greece, present fossil rodent and insectivore faunal assemblages and their chronology for select loci, and discuss the applicability of ...

Migration of the Antarctic Polar Front through the mid-Pleistocene transition: evidence and climatic implications [PDF]

, 2010
The Antarctic Polar Front is an important biogeochemical divider in the Southern Ocean. Laminated diatom mat deposits record episodes of massive flux of the diatom Thalassiothrix antarctica beneath the Antarctic Polar Front and provide a marker for ...

Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

Meteoritics &Planetary Science, EarlyView.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

Neotropical Snakes Reveal Different Geological Times for Dispersal Corridors Between Amazon and Atlantic Forests

Zoologica Scripta, EarlyView.
ABSTRACT Three forested dispersal corridors have been proposed within the diagonal of open/dry landscapes in South America and the relative importance of each one has been the subject of debate for forest organisms. We analysed the biogeographical history of three snake genera (Bothrops, Philodryas, and Micrurus) from different families (Viperidae ...

MAGNETOSTRATIGRAPHIC INVESTIGATION OF THE UPPER SIVALIKS NEAR PINJOR, INDIA

Rivista Italiana di Paleontologia e Stratigrafia, 2023
A magnetostratigraphic study on four sections near Pinjor showed that the Tatrot stage falls in the Gauss magnetic epoch and the Pinjor corresponds to most of the Matuyama epoch. A significant faunal change, already observed by other authors in Pakistan,

The African Mole‐Rat Genus Cryptomys and Its Species: Distinct in Their Genes and Habitats

Zoologica Scripta, EarlyView.
ABSTRACTThe African mole‐rat genus Cryptomys comprises five morphologically cryptic lineages distributed across South Africa and in Zimbabwe, historically treated as subspecies of C. hottentotus (C. h. hottentotus, C. h. mahali, C. h. natalensis, C. h. pretoriae and C. h. nimrodi).
