The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

open access: yesArchaeometry, EarlyView.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

open access: yesArchaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

open access: yesConservation Biology, EarlyView.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Decadal changes in environmental suitability for the margay (Leopardus wiedii) under anthropogenic pressure in the Yucatán Peninsula

open access: yesConservation Science and Practice, EarlyView.
This study evaluates how human activities impact margay (Leopardus wiedii) distribution in the Yucatán Peninsula, revealing habitat loss due to agriculture but also recolonization opportunities in abandoned lands. Species distribution models show range contraction (2010–2023), yet margays demonstrate resilience near disturbed habitats.

Who prefers the dark? Daily activity of dung beetles from an Amazonian region

open access: yesEcological Entomology, EarlyView.
Daily activity patterns shape how dung beetle species coexist in Amazonian forests, revealing temporal niches that reduce competition and structure biodiversity. We compared species richness, abundance and assemblage composition of dung beetles sampled during day and night in a conserved terra‐firme forest in the Brazilian Amazon. Although richness and

Mental health in parents of very preterm infants at 12 months: Influential variables and profiles

open access: yesFamily Relations, EarlyView.
Abstract Objective The goal was to explore the influence of clinical and developmental variables of the infant on the mental health of parents at12 months corrected age of very preterm babies. Background There is no agreement on whether all parents of preterm infants need the same specialized attention in the neonatal intensive care unit and during ...
