Hominin palaeoecology in Late Pliocene Malawi : first insights from isotopes (13C, 18O) in mammal teeth [PDF]

open access: yes, 2011
Carbon-13 and oxygen-18 abundances were measured in large mammal skeletal remains (tooth enamel, dentine and bone) from the Chiwondo Beds in Malawi, which were dated by biostratigraphic correlation to ca. 2.5 million years ago.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Evidence of a true pharyngeal tonsil in birds: a novel lymphoid organ in Dromaius novaehollandiae and Struthio camelus (Palaeognathae)

open access: yesFrontiers in Zoology, 2012
Background Tonsils are secondary lymphoid organs located in the naso- and oropharynx of most mammalian species. Most tonsils are characterised by crypts surrounded by dense lymphoid tissue. However, tonsils without crypts have also been recognised.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

open access: yesAnimal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Tick‐Tac‐Foe: When Ticks, Trade, and Zoonotic Pathogens Align in African Wet Meat Markets

open access: yesPublic Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Zoonotic diseases account for over ∼60% of infectious diseases and present a significantly growing fatality threat in Africa. Live and wet markets (LWMs) in Africa function as key economic venues that support human livelihoods through social interaction and trade in food stuff, including meat and other animal‐based products.

Impact of Freezing on the Nanoarchitecture and Techno‐Functional Properties of Camel Myofibrillar Proteins: Insights From Atomic Force Microscopy

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
Schematic overview of the extraction of camel myofibrillar proteins from Longissimus lumborum (LL) and Biceps femoris (BF) muscles and the evaluation of freezing‐induced changes. The study integrates techno‐functional analyses (protein solubility, surface hydrophobicity, reactive sulfhydryl groups, SDS–PAGE) with nanoarchitectural characterization ...

Lactoferrin and Immunoglobulin Contents in Camel's Milk (Camelus bactrianus, Camelus dromedarius, and Hybrids) from Kazakhstan [PDF]

open access: yesJournal of Dairy Science, 2007
Lactoferrin (Lf) and IgG were estimated in camel's milk from Kazakhstan, where 2 species of camels (Camelus bactrianus, Camelus dromedarius) and their hybrids cohabit. The concentrations of Lf and IgG were determined according to 3 variation factors: region (n = 4), season (n = 4), and species (n = 5; sample 4 was mixed milk and sample 5 was of unknown

Seroprevalence of Neospora caninum in Camelids of the New and Old World: A Global Systematic Review and Meta‐Analysis

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Based on the present systematic review and meta‑analysis, the pooled prevalence of N. caninum in camelids was 10% (95% CI: 7%–12%) with significant heterogeneity (I2 = 93.75%, p < 0.0001). The highest rate was detected in Old World camelids, 14% (95% CI: 10%–19%), indicating that this group is more susceptible to N. caninum exposure.
