Between the Indian Ocean and the Gulf: Ceramics From Ḥattā Oasis in the Emirate of Dubai
Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT This study presents the ceramic finds from archaeological investigations conducted in 2024 at two settlements: ‘Islamic Village' and Suhaila 2, one of a number of mountain villages of the Late Islamic period within the Ḥattā Oasis: a high‐altitude exclave in the Emirate of Dubai. The sites are located on the northeastern slopes of Jabal Qallāt

Microbiome Dynamics During Translocation of the Critically Endangered Frog Craugastor ranoides
Animal Conservation, EarlyView.A female Craugastor ranoides fitted with an LB‐2X radio transmitter using a silicone waist‐belt harness for post‐translocation monitoring. ABSTRACT Amphibian populations are declining, and species are going extinct due to habitat loss, climate change, and emerging infectious disease, prompting the increasing use of translocations as a conservation tool.

Response of an endangered dipterocap tree species to nutrient addition in a problematic soil
Annals of Tropical Research, 2019 The successful establishment of dipterocarp tree species especially in problematic lands is a challenge since it is still poorly understood. The study was conducted to evaluate the effects of the addition of N, P, and K to Yakal-yamban (Shorea ...

MORPHOLOGICAL AND COMPOSITIONAL FEATURES OF CHROMIAN SPINEL FROM MANTLE ULTRAMAFIC ROCKS OF THE NURALI MASSIF (SOUTH URALS) [PDF]
Минералогия, 2019 Accessory chromian spinels of lherzolites and dunites from a mantle section of the Nurali ophiolite massif are described in the paper. Lherzolites typically host anhedral chromian spinel grains associated with olivine, pyroxenes and plagioclase.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen
The FEBS Journal, EarlyView.Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,
