Beyond first clutches: Second broods reshape selection on breeding timing in forest and urban great tits

Journal of Animal Ecology, EarlyView.
Most studies of selection on breeding timing consider only first clutches. Using a 13‐year dataset of urban and forest great tits, we show that including second broods reshapes estimates of natural selection, revealing that early breeding is favoured through increased probability of multiple brooding and higher annual reproductive output.

REPRODUCING OPERATIONAL LANDSCAPES: The Rock Mining for Indonesia's New Capital City

International Journal of Urban and Regional Research, EarlyView.
Abstract Indonesia's new capital city is designed to become a green and sustainable city. In this article, we examine the (un)sustainability of the process through which the city is coming into being. Using the sociospatial theory of planetary urbanization, we trace the dialectical relationship between the new city and sites beyond it to show how ...

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

Arabian 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.

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Comparative anticancer and antimicrobial activity of aerial parts of Acacia salicina, Acacia laeta, Acacia hamulosa and Acacia tortilis grown in Saudi Arabia

Saudi Pharmaceutical Journal, 2017
The standardized ethanol extract (EE) of aerial parts of four Acacia species [A. salicina (ASEE), A. laeta (ALEE), A. hamulosa (AHEE), and A. tortilis (ATEE)] were examined in order to compare their cytotoxic and antimicrobial activities. All the extracts were standardized by UPLC- PDA method using rutin as standard compound.

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

An Archaeometric Approach to Reveal Organic Compounds via GC‐MS Analyses of Two Discovered Incense Burners at Daba Al‐Bayah

Archaeometry, EarlyView.
ABSTRACT This study focuses on two terracotta incense burners discovered in the Daba Al‐Bayah necropolis in the Musandam Peninsula (Oman), associated with an Iron Age collective tomb (LCG‐2). Through gas chromatography–mass spectrometry (GC‐MS), the organic residues preserved within these artifacts were analyzed to investigate their use and ...
