Uncovering Biogas Outcomes: Tales of Hubris, Hope, and Failure From Southern Malawi

Natural Resources Forum, EarlyView.
ABSTRACT The purpose of this article is to speak directly to biogas failure. Over the past two decades, immense amounts of money have been spent by African governments, private individuals, and most conspicuously, international aid agencies and donors, on countless biogas projects in every country on the continent.

Climatic conditions, landscape, and habitat quality drive patch occupancy and larval density of a threatened mire butterfly

Insect Science, EarlyView.
The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.

Sex‐Specific Involvement of Gut Microbiota in Behavioral and Endocrine Responses to Chronic Predator Odor in Brandt's Voles

Integrative Zoology, EarlyView.
18 days of predator odor exposure altered gut microbiota, increased anxiety‐like behaviors, and elevated hypothalamic–pituitary–adrenal axis activity in Brandt's voles, with males showing behavioral habituation and females remaining sensitive. Cecal microbiota transplantation experiments confirmed that only female recipients of microbiota from predator‐

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.
