Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)

open access: yesCladistics, EarlyView.
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

The evolution of ephemeral flora in Xinjiang, China: insights from plastid phylogenomic analyses of Brassicaceae

open access: yesBMC Plant Biology
Background The ephemeral flora of northern Xinjiang, China, plays an important role in the desert ecosystems. However, the evolutionary history of this flora remains unclear.

Middle Miocene climate instability associated with high‐amplitude CO2 variability

open access: yes, 2014
The amplitude of climatic change, as recorded in the benthic oxygen isotope record, has varied throughout geological time. During the late Pleistocene, changes in the atmospheric concentration of carbon dioxide (CO2) are an important control on this ...

Homo luzonensis and the role of homoplasy in the morphology of hominin insular species

open access: yesCladistics, EarlyView.
Abstract Homo luzonensis lived during the upper Pleistocene in the northern Philippines, east of the Wallace line. The few specimens attributed to this species show a mosaic of plesiomorphies for the genus Homo and apomorphies found in upper Pleistocene Homo species.

Spatial distribution and tectonic framework of fossil tubular concretions as onshore analogues of cold seep plumbing systems, North Island of New Zealand

open access: yesBSGF - Earth Sciences Bulletin, 2017
Analysis of offshore seismic lines suggests that a strong relationship exists between tectonic structures and fluid migration in accretionary prisms.

Late Eocene to middle Miocene (33 to 13 million years ago) vegetation and climate development on the North American Atlantic Coastal Plain (IODP Expedition 313, Site M0027)

open access: yes, 2014
. We investigated the palynology of sediment cores from Site M0027 of IODP (Integrated Ocean Drilling Program) Expedition 313 on the New Jersey shallow shelf to examine vegetation and climate dynamics on the east coast of North America between 33 and 13 ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.
