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

Archaeometry, 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 ...

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

Archaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.

Deforestation and resource disputes in Papua New Guinea

Asian Economic Journal, EarlyView.
Abstract Disputes over land and other resources are common in poor areas of Asia and the Pacific, where common pool resources matter for livelihoods, property rights are poorly defined, and state capacity for dispute resolution is low. For example, in Papua New Guinea (PNG), the subject of the current study, one‐quarter of households experience land ...

Haematology and biochemistry parameters for koalas (Phascolarctos cinereus) on Raymond Island, Victoria: use of point‐of‐care analysers

Australian Veterinary Journal, EarlyView.
Biochemistry and haematology analytes can provide information on the health status of individual animals or populations in direct comparison to expected values or reference intervals developed using the same analysis methodology from a healthy reference population of the target species. Point‐of‐care analysers are increasingly used in the assessment of

Authoring Terrestrial Planets with Diffusion Models

Computer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

The significance of the pycnocline in tropical lakes

, 1972
The vertical temperature profile is a poor indicator of sratification in most tropical lake. Data from Lake Bunyonyi, Uganda, showed, however, that the density profile highlighted discontinuity layers whieh were not obvious from the temperature profile, It is suggested that the verticaldensity profile and the region of maximum discontinuity, the ...

Presenting the scientific discourse of biodiversity loss through drivers, solutions, and responsibilities

Conservation Biology, EarlyView.
Abstract Biodiversity loss is considered a major global issue, but at the same time, scientists interpret it differently, identifying varied drivers, solutions, and responsibilities in their published works. These interpretations shape the scientific narratives these scientists use to discuss biodiversity loss, which, in turn, affects policy through ...

Local environment shapes habitat suitability of the endangered mint Dicerandra cornutissima

Conservation Science and Practice, EarlyView.
Using a fine‐scale ecological niche model at 250 m resolution, we identified suitable habitat for the extremelynarrow endemic Dicerandra cornutissima across its known and surrounding range. Field validation confirmed characteristic habitat at predicted suitable sites, while gap analysis showed that only 26% of suitable habitat occurs within protected ...
