Performance of point‐of‐care tests for diagnosing feline immunodeficiency virus infection in captive African lions (Panthera leo)

open access: yesAustralian Veterinary Journal, EarlyView.
Point‐of‐care (PoC) antibody (Ab) testing forms an integral component of feline immunodeficiency virus (FIV) diagnosis in both domestic and non‐domestic felids, with test kits designed for use in domestic cats frequently extrapolated for use in their wild counterparts. The SNAP® FIV/FeLV Combo lateral flow ELISA is commonly used to assign FIV infection

Rapid progradation of the Pliocene-Pleistocene continental margin, northern Taranaki Basin, New Zealand, and implications [PDF]

open access: yes, 2004
Progradation and aggradation of the modern continental margin in northern Taranaki Basin has resulted in the deposition of a thick and rapidly accumulated Pliocene-Pleistocene sedimentary succession.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

The Pliocene environment of Antarctica [PDF]

open access: yesPapers and Proceedings of the Royal Society of Tasmania, 1996
Debate continues about the environment of Antarctica during intervals in the Pliocene (5.2-1.8 Ma), particularly during the Late Pliocene (3.5-1.8 Ma). Two schools of thought - dynamic versus stable ice sheet - have developed. One hypothesis calls for the Antarctic ice sheet to vary dramatically, for Antarctica at times to be vegetated and for circum-

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

On the Pliocene Flora of Transcaucasia [PDF]

open access: yesGeological Magazine, 1922
It is well known that the existing flora of Western Caucasia is of great interest from the point of view of the origin of the floras of Europe and Asia, as in it have survived to this day numerous types of plants which were widely spread over the Northern Hemisphere during Tertiary times.

Changes in land‐snail communities and steppe environments in the lower Rhône valley during the Lateglacial–Holocene transition

open access: yesBoreas, EarlyView.
Land snail successions in the lower Rhône valley allow us to reconstruct the postglacial recolonization. From the Lateglacial period onwards, Mediterranean steppe communities appeared. The arrival of forest taxa was significantly delayed by aridity. The question of glacial refugia, both local and distant, primarily concerned Mediterranean species of ...

Tracing Ancient Migration Routes: Did <i>Gloydius</i> Pitvipers Disperse Across Paleo-Tibet Through Temperate and Subtropical Corridors? [PDF]

open access: yesEcol Evol
We investigated the evolutionary and biogeographic history of Himalayan and Hindu Kush Gloydius pitvipers by integrating time‐calibrated phylogenetic analyses with paleoclimatic reconstructions and species distribution modeling. Our results suggest an early Miocene origin in East and Southeast Asia, followed by westward dispersal across Paleo‐Tibet via

Pliocene-Pleistocene biostratigraphy in the Tyrrhenian Sea

open access: yes, 1990
The distribution of stratigraphically important calcareous nannofossils and planktonic foraminifera has been investigated in the Pliocene-Pleistocene sequences of ODP Sites 652, 653, and 654 (Tyrrhenian Sea-western Mediterranean).

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

open access: yesCladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological
