Advanced Science, EarlyView.Lipoic acid synthase (lias) can regulate α‐KG levels through lipoylation, thereby negatively regulating HIF‐1α protein levels via PHD under hypoixa. The Hap2 allele of lias exhibits lower expression levels than Hap1, leading to the accumulation of more HIF‐1α protein and thereby enhancing hypoxia tolerance. ABSTRACT Hypoxia stress seriously affects the

Sex allocation and reproductive costs in a gull with a long breeding season
, 2004 The Silver Gull is a small gull (265 - 450g), which exhibits sexual dimorphism, with males larger than females. It has a protracted laying period of about 8 months over the winter on Penguin Island in Western Australia.

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Amid rising food and fertilizer prices, understanding farmers' policy preferences is critical for effective crisis response. We use best‐worst scaling experiment to assess Kenyan mobile‐owning crop farmers' preferences for government support under high and normal price scenarios.

Life history trade-offs between survival, moult and breeding in a tropical season environment
, 2011 The trade-off between current and future investment in reproduction lies at the heart of life history theory. The need to differentially allocate resources between these two options arises generally as a result of environmental pressures.

Habitat selection and breeding ecology of three species of waders in the western isles of Scotland [PDF]
, 1988 The habitat requirements and population dynamics of Redshank, Dunlin and Ringed Plover on internationally important breeding grounds in the Western Isles of Scotland were studied from 1985 to 1987 using individually colour-ringed birds.

Ban Glyphosate—Does It Affect the Swedish Farmers' Willingness to Grow Cover Crops?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The cultivation of cover crops is one of the new Eco‐scheme practices introduced in Sweden. This study examines how the design of policy attributes of these schemes influences farmers' willingness to grow cover crops on arable land, with particular focus on the potential impact of a glyphosate ban.

Understanding Egg Price Volatility and Policy Implications in the U.S. With Machine Learning
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Eggs are an inexpensive and sustainable source of proteins, but volatility in the U.S. egg prices has intensified in recent years, raising concerns over food affordability and market stability. This study examines the drivers of U.S. egg price dynamics over 2004–2025 using a two‐stage framework that combines LASSO‐based variable selection with
