‘Missing persons’: Ancient legacies of human–environment interaction in tropical natural properties inscribed under the 1972 World Heritage Convention

open access: yesArchaeometry, EarlyView.
Abstract Cultural and natural values form the core of World Heritage designation. Properties displaying both values, however, comprise a fraction of inscriptions (currently c. 3%) to the World Heritage List. In 1992, when that fraction stood at c. 5%, adoption of the popular ‘cultural landscapes’ category of cultural heritage in 1992 was therefore ...

Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Ice in the Tropics: the Export of ‘Crystal Blocks of Yankee Coldness’ to India and Brazil [PDF]

open access: yes, 2011
The Boston natural ice trade thrived during 1830-70 based upon Frederic Tudor’s idea of combining two useless products – natural winter ice in New England ponds and sawdust from Maine’s lumber mills. Tudor ice was exported extensively to the tropics from

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.

Taxonomy Of Thermopsis (Fabaceae) In North-America [PDF]

open access: yes, 1994
Comprehensive reevaluation of both herbarium specimens and field observations of the North American Thermopsis leads to our recognition of 10 species. Three species occur in the southern Appalachians: T. villosa, T. mollis, and T. fraxinifolia. The Rocky

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Integrative phylogenomics and morphology reveal the evolution and biogeography of Encephalartos (Zamiaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
We aimed to conduct phylogenetic analyses of Encephalartos, a cycad genus endemic to Africa, using 3545 single‐copy nuclear genes extracted from transcriptome data, covering 64/65 of the recognized species, along with inference of divergence times using two secondary calibration points.
