A baseline paleoecological study for the Santa Cruz Formation (late–early Miocene) at the Atlantic coast of Patagonia, Argentina
(Palaeogeography, Palaeoclimatology, Palaeoecology, 2010-06)Coastal exposures of the Santa Cruz Formation (late-early Miocene, southern Patagonia, Argentina) between the Coyle and Gallegos rivers have been a fertile ground for recovery of Miocene vertebrates for more than 100 years. ... -
A classification for extant ferns
(Taxon, 2006-01-01)We present a revised classification for extant ferns, with emphasis on ordinal and familial ranks, and a synopsis of included genera. Our classification reflects recently published phylogenetic hypotheses based ... -
A diploids-first approach to species delimitation and interpreting polyploid evolution in the fern genus astrolepis (pteridaceae)
(Systematic Botany, 2010-04-01)Polyploidy presents a challenge to those wishing to delimit the species within a group and reconstruct the phylogenetic relationships among these taxa. A clear understanding of the tree-like relationships among the diploid ... -
A molecular phylogeny of scaly tree ferns (Cyatheaceae).
(American journal of botany, 2007-05)Tree ferns recently were identified as the closest sister group to the hyperdiverse clade of ferns, the polypods. Although most of the 600 species of tree ferns are arborescent, the group encompasses a wide range of morphological ... -

A novel approach to assess livestock management effects on biodiversity of drylands
(Ecological Indicators, 2015-01-01)In drylands livestock grazing is the main production activity, but overgrazing due to mismanagement is a major cause of biodiversity loss. Continuous grazing around water sources generates a radial gradient of grazing intensity ... -
A numerical analysis of chromatographic profiles in North American taxa of the fern genus Gymnocarpium
(Canadian Journal of Botany, 1983-10-01)<jats:p> As part of a systematic investigation of the genus Gymnocarpium in North America, a survey of chromatographic profiles in species and hybrids of the genus was initiated. It was established through cluster analysis ... -
A plastid phylogeny of the cosmopolitan fern family cystopteridaceae (Polypodiopsida)
(Systematic Botany, 2013-06-01)Among the novel results of recent molecular phylogenetic analyses are the unexpectedly close evolutionary relationships of the genera Acystopteris, Cystopteris, and Gymnocarpium, and the phylogenetic isolation of these genera ... -

A revised family-level classification for eupolypod II ferns (Polypodiidae: Polypodiales)
(Taxon, 2012-01-01)We present a family-level classification for the eupolypod II clade of leptosporangiate ferns, one of the two major lineages within the Eupolypods, and one of the few parts of the fern tree of life where family-level ... -
A revised generic classification of vittarioid ferns (Pteridaceae) based on molecular, micromorphological, and geographic data
(Taxon, 2016-08-01)© International Association for Plant Taxonomy (IAPT) 2016. Vittarioid ferns compose a well-supported clade of 100-130 species of highly simplified epiphytes in the family Pteridaceae. Generic circumscriptions within the ... -
A Structural Event Approach to the Analysis of Group Composition
(Social Networks, 2002)Since Simmel's early work on forms of association, the processes guiding group composition have commanded considerable attention in structural sociology, but have not led to a general methodology for examining compositional ... -
A synopsis of the genus Sanicula (Apiaceae) in eastern Canada
(Canadian Journal of Botany, 1989-01-01)Four species and 2 varieties of these native woodland umbellifers are recognized. A key to the taxa, comparative descriptions of diagnostic characters, and notes on the taxonomy, distribution, habitat, and rare status are ... -
A worldwide phylogeny of Adiantum (Pteridaceae) reveals remarkable convergent evolution in leaf blade architecture
(Taxon, 2018-06-01)© International Association for Plant Taxonomy (IAPT) 2018, All rights reserved. Adiantum is among the most distinctive and easily recognized leptosporangiate fern genera. Despite encompassing an astonishing range of leaf ... -

Age-Related Adverse Inflammatory and Metabolic Changes Begin Early in Adulthood.
(The journals of gerontology. Series A, Biological sciences and medical sciences, 2018-05-22)Aging is characterized by deleterious immune and metabolic changes, but the onset of these changes is unknown. We measured immune and metabolic biomarkers in adults beginning at age 30. To our knowledge, this is the first ... -
American Society for Enhanced Recovery: Advancing Enhanced Recovery and Perioperative Medicine.
(Anesthesia and analgesia, 2018-06)As the population ages, the increasing surgical volume and complexity of care are expected to place additional care delivery burdens in the perioperative setting. In this age of integrated multidisciplinary care of the surgical ...
