Automating the analysis of public saliency and attitudes toward biodiversity from digital media
Conservation Biology, EarlyView.Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.

Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段
Ecological Entomology, EarlyView.The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Shuitu Baochi Xuebao, 2005 用草酸、草酸钠、柠檬酸和柠檬酸钠作为活化剂，加人不同含磷水平土壤中，通过室内培养试验和分析，结果表明：(1)0．1M草酸和0．1M柠檬酸都有一定的活化土壤磷素的作用，草酸作用最为显著。而相同浓度的草酸钠和柠檬酸钠未显示对土壤磷素的活化效果。(2)对土壤磷素的活化作用，草酸随其浓度的增加而增强，而柠檬酸活化土壤磷的能力有限。(3)柠檬酸在加人的6h之内，对活化土壤速效磷作用明显；而草酸在加人的48h之内，对活化土壤速效磷有十分显著的作用。无论是柠檬酸还是草酸，在其对土壤速效磷发挥活化作用期间 ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

The Role of Technology Standards in Strategic Hedging
Asian Politics &Policy, Volume 18, Issue 2, April 2026.ABSTRACT This article argues that technology standards provide Southeast Asian states with a distinct mechanism for hedging amid intensifying US–China technological rivalry. Traditional hedging strategies emphasizing economic engagement without political alignment are increasingly constrained by the weaponization of technological interdependence ...
