From bad omens to commodities: Uncovering the spatiotemporal patterns and socio‐economic factors of online crow trade on Baidu Tieba using artificial intelligence

People and Nature, EarlyView.
Abstract High demand for wild birds as pets stimulates overexploitation and threatens global avian biodiversity. Unlike commonly traded birds valued for colourful plumage or attractive songs, crows (e.g. Corvus, Pyrrhocorax and Coloeus) have increasingly appeared in online records of rearing, acquisition and trade, yet these activities remain ...

Informing the potential of mature temperate forests as natural climate solutions: Changed fine root biomass and morphology under elevated CO2

PLANTS, PEOPLE, PLANET, EarlyView.
The land carbon sink absorbs approximately 25% of anthropogenic CO2 emissions, with forests accounting for most. Managing forests as Natural Climate Solutions is therefore a societal imperative, requiring models of where and how long carbon resides within these ecosystems. We investigated the effects of elevated CO2 on fine roots, the primary source of

FORECASTING THE LONGITUDINAL MOVEMENTS OF UNDERGROUND PIPELINES

Problems of Gathering Treatment and Transportation of Oil and Oil Products
Main pipelines laid in low-bearing soil conditions are subject to changes in their design position, which affects the reliability of natural gas transportation. Achieving and maintaining the required reliability of the linear part of main gas pipelines is of particular importance.

Plant species are more important to bacterial community composition than seeding ratio in a pea‐canola intercropping system

PLANTS, PEOPLE, PLANET, EarlyView.
Demand for agricultural land has increased due to rising demand for food, potentially leading to expansion into previously untouched habitats, which threatens refugia of native plants. We aimed to provide insight into how variation in seeding ratio may impact soil bacterial communities in a pea‐canola intercropping system, potentially altering crop ...

Food plant diversity in a rapidly changing world

PLANTS, PEOPLE, PLANET, EarlyView.
Diversity in food plants is essential to human and planetary health. On farms, in diets, and in many other areas of food systems, this diversity has undergone enormous change globally, including significant decline. We describe major trends in how food plant diversity has been changing, note the responses from conservation communities, highlight gaps ...

A composite, host‐participatory haustorium links host compatibility to defence bifurcation in Alectra vogelii (Orobanchaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Parasitic weeds of the family Orobanchaceae are among the most damaging constraints on food production in the tropics, draining water and nutrients from their hosts and threatening the livelihoods of millions of smallholder farmers. Yellow witchweed (Alectra vogelii) can destroy entire legume harvests across sub‐Saharan Africa, where these crops are a ...
