Biogeographic and evolutionary patterns of change in the terrestrial biota across the Cretaceous\Tertiary boundary [PDF]

The Paleontological Society Special Publications, 1992
The currently available fossil record suggests, 1) biogeographic differentiation of the Late Cretaceous terrestrial biota and, 2) distinctly different patterns of evolution of terrestrial faunas and floras across the Cretaceous\Tertiary boundary.Discovery in Alaska of dinosaurs and mammals that lived at Late Cretaceous northern high latitudes provides ...

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India

Nordic Journal of Botany, EarlyView.
A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

Reply to ‘Dissimilarity measures affected by richness differences yield biased delimitations of biogeographic realms’

Nature Communications, 2018
Recently, we classified the oceans into 30 biogeographic realms based on species’ endemicity. Castro-Insua et al. criticize the choices of dissimilarity coefficients and clustering approaches used in our paper, and reanalyse the data using alternative ...

Rediscovery of Strobilanthes panichanga and discovery of Strobilanthes parryorum (Acanthaceae): two endangered species from the hills of Dima Hasao, Assam, India

Nordic Journal of Botany, EarlyView.
We report on two species of Strobilanthes Blume. Strobilanthes panichanga (Nees) T.Anderson has been rediscovered in the Dima Hasao district of Assam, India, after a very long gap of 150 years, and Strobilanthes parryorum C.E.C.Fisch has been discovered for the first time in Assam, India.

Species Limits and Phylogeography of North American Cricket Frogs (Acris: Hylidae) [PDF]

, 2008
Cricket frogs are widely distributed across the eastern United States and two species, the northern cricket frog (Acris crepitans) and the southern cricket frog (A. gryllus) are currently recognized. We generated a phylogenetic hypothesis for Acris using

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, EarlyView.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...

The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

Oikos, EarlyView.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.

Bridging a biogeographic 'gap' : microfossil evidence for the quillwort Isoetes on the Cumberland Plain west of Sydney during the early Colonial period [PDF]

, 2013
Fossil spores preserved on historical archaeological sites at Parramatta and Richmond indicate that two or more species of the quillwort genus Isoetes (family Isoetaceae) were growing along rivers on the Cumberland Plain, west of Sydney, during the late ...

Differential temporal beta‐diversity patterns of native and non‐native arthropod species in a fragmented native forest landscape [PDF]

, 2018
An important factor that hinders the management of non‐native species is a general lack of information regarding the biogeography of non‐natives, and, in particular, their rates of turnover.
