During the latest Cretaceous, the European Archipelago was characterized by highly fragmented landmasses hosting putative dwarfed, insular dinosaurs, claimed as fossil evidence of the "island rule". The Villaggio del Pescatore quarry (north-eastern Italy) stands as the most informative locality within the palaeo-Mediterranean region and represents the first, multi-individual Konservat-Lagerstätte type dinosaur-bearing locality in Italy. The site is here critically re-evaluated as early Campanian in age, thus preceding the final fragmentation stages of the European Archipelago, including all other European localities preserving hypothesized dwarfed taxa. New skeletal remains allowed osteohistological analyses on the hadrosauroid Tethyshadros insularis indicating subadult features in the type specimen whereas a second, herein newly described, larger individual is likely somatically mature. A phylogenetic comparative framework places the body-size of T. insularis in range with other non-hadrosaurid Eurasian hadrosauroids, rejecting any significant evolutionary trend towards miniaturisation in this clade, confuting its 'pygmy' status, and providing unmatched data to infer environmentally-driven body-size trends in Mesozoic dinosaurs.

Objectives: This study evaluated the influence of genetic diversity, subsistence strategies, age at death, and their interplay on the prevalence of linear enamel hypoplasias (LEHs) in the indigenous populations of the Canary Islands. Additionally, we test the predictive adaptive hypothesis and the plasticity/constraint hypothesis within this unique archeological context.
Methods: LEH incidence, age of occurrence, and the number of stress episodes were assessed macroscopically in a sample of 409 individuals from six of the seven islands comprising the Canarian archipelago during the pre-contact or Indigenous period (2nd-15th century cal CE).

The frequency of specific variants associated with the risk of developing cardiovascular diseases has been extensively studied through genome-wide association studies (GWASs). Differences between populations may be caused by the interaction of several factors, such as environmental and genetic backgrounds. Here, we studied 19 SNPs involved in atherosclerosis (AT) and venous thromboembolism (VTE) risk in the Azorean and mainland Portuguese populations and compared their frequencies with other European, Asian, and African populations.

Unlabelled: The Upper Cretaceous European vertebrate fossil record has improved significantly in the past three decades but there still remain chronostratigraphic and geographic gaps, which obscure our understanding of the paleobiogeography and evolution within the insular environments of the Late Cretaceous European Archipelago. Recently, a new vertebrate locality of late Santonian-early Campanian age was discovered in westernmost Bulgaria, promising to fill some of these gaps. Here, we use a multidisciplinary approach involving palynology, paleontology and paleohistology to investigate aspects of the paleoecology and taphonomy of this new locality and to provide preliminary information on its taxonomic contents.

While the seaweed industry is developing worldwide, the untapped diversity of species in New Caledonia offers many opportunities for value-added products that can stimulate the local blue economy. However, human activities and the particular geology of the archipelago can release contaminants into the marine environment. Seaweeds bioaccumulate heavy metals and other contaminants from their growing environment, which can pose a significant food safety concern and a barrier to developing seaweed-based products.

Across the world, human (anthropophonic) sounds add to sounds of biological (biophonic) and geophysical (geophonic) origin, with human contributions including both speech and technophony (sounds of technological devices). To characterize society's contribution to the global soundscapes, we used passive acoustic recorders at 139 sites across 6 continents, sampling both urban green spaces and nearby pristine sites continuously for 3 years in a paired design. Recordings were characterized by bird species richness and by 14 complementary acoustic indices.
