Small Bugs, Big Data: Metagenomics for Arthropod Biodiversity Monitoring

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We used metagenomic sequencing of 40 bulk arthropod samples collected across Sweden to classify taxa and compare results with metabarcoding from the same samples. While metabarcoding was more sensitive for detecting low‐abundance taxa, taxonomic overlap between methods was strongly influenced by reference database representation.

Gestation and the evolution of vertical stance bipedal humans [PDF]

open access: yes, 2011
During mammalian gestation a change in maternal stance alters the velocities of maternal blood flows and results in a changed rate of delivery and distribution of nutrients required to form the bone and tissue in various parts of a developing foetus. The

Evolucija hominida (por. Hominidae) [PDF]

open access: yes, 2014
Evolution of hominids covers the period of the last 60 million years and it refers on the developement of apes and humans. The process of evolution has in a way been conditioned by the changes that arrose during time, and they included tectonic movements of the Earths crust, ocean draining and climate change – all of which made severe impact on the ...

Wild Encounters: Analyzing Human–Animal Interactions in British and Irish Association of Zoos and Aquariums Facilities

open access: yesZoo Biology, Volume 44, Issue 5, Page 461-473, September/October 2025.
We investigated the quantity and diversity of animal–visitor interactions in BIAZA‐accredited facilities, finding 740 opportunities for interactions across a range of contexts including walkthroughs and handling. Meet and greets were the most offered and were influenced by the number of individual animals, cost of interaction, and animal popularity ...

The prion protein and New World primate phylogeny [PDF]

open access: yes, 2004
The PrPC prion protein contains 250 amino acids with some variation among species and is expressed in several cell types. PrPC is converted to PrPSc by a post-translational process in which it acquires amino acid sequences of three-dimensional ...

Morphofunctional Space of the Forelimb in Caraguatypotherium munozi (Notoungulata; Mesotheriidae): Insights Into Wrist‐Powered Digging

open access: yesJournal of Morphology, Volume 286, Issue 8, August 2025.
Caraguatypotherium munozi displays a distinctive morphofunctional configuration combining high wrist flexor leverage with reduced elbow mechanical advantage—traits consistent with wrist‐dominated scratch‐digging. Multivariate analyses place it outside the core morphospaces of extant locomotor groups.

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

open access: yesJournal of Quaternary Science, Volume 40, Issue 6, Page 925-943, August 2025.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Predomination and new genotypes of Enterocytozoon bieneusi in captive nonhuman primates in zoos in China: high genetic diversity and zoonotic significance.

open access: yesPLoS ONE, 2015
To appreciate the genetic diversity and zoonotic implications of Enterocytozoon bieneusi in nonhuman primates (NHPs) in zoos, we genotyped E. bieneusi in captive NHPs in seven zoos located at six major cities in China, using ribosomal internal ...

Insights into the Middle Pleistocene fauna of South Africa: Zooarchaeology, stable isotopes and dating of Pniel 6

open access: yesJournal of Quaternary Science, Volume 40, Issue 6, Page 1120-1139, August 2025.
ABSTRACT The Florisian Land Mammal Age (FLMA; 773‐12 ka) is characterised by specialist, often extinct, grazing as well as wetland species, many of which are no longer present in the southern African interior. Middle Pleistocene FLMA faunal assemblages are rare, particularly those associated with artefacts, limiting reconstruction of environmental ...
