On the normative roles of biodiversity and naturalness in conservation. [PDF]
Conserv BiolAbstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States. [PDF]
Conserv BiolAbstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

Feeding the future in Ghana: Gender inequality, poverty, and food insecurity
World Medical &Health Policy, Volume 15, Issue 4, Page 638-671, December 2023., 2023 Abstract As women's empowerment is critical for the adoption of agricultural technologies by farmers, some governments have over the last three decades adopted a gender equality approach to food security. In Ghana, women play a vital role as farmers and food processors, which means they impact household nutrition in important ways.

Veterinary Dermatology, Volume 33, Issue 6, Page 523-526, December 2022., 2022 Background: There is increasing evidence of cross‐reactivity between allergens of close or distant species. The A‐RISC (Allergens'–Relative Identity, Similarity and Cross‐reactivity) index helps evaluate the risk of theoretical cross‐reactivity between proteins of the same family among different species.

Shuitu Baochi Xuebao, 2021 为探究不同灌水和施肥条件对河套灌区不同生育期玉米生长的影响，以玉米"金苹628"为材料，分别研究了低水（1 800 m3/hm2）、中水（2 250 m3/hm2）、高水（2 700 m3/hm2）3个灌水水平，低肥（300 kg/hm2）、中肥（375 kg/hm2）、高肥（450 kg/hm2）3个施肥水平，并以当地一般灌水量和施肥量为对照（CK），共10个处理在苗期、拔节、抽雄、灌浆、成熟期对土壤水分、养分和玉米生长的影响。结果表明：拔节期以后，土壤平均含水率呈下降趋势；抽雄和灌浆期玉米耗水量最大，

Shuitu Baochi Xuebao, 2006 通过盆栽模拟干旱试验，测定了干旱胁迫下玉米根系生长情况和根际土壤中速效N、P、K的含量。结果表明，干旱胁迫抑制了玉米拔节期和抽雄-开花期玉米根系的生长，减弱了玉米根系的吸收能力。干旱胁追下玉米根际NH4^＋-N、NO3^--N、速效P和速效K均发生根际富集现象。其中有效N和速效K含量高于正常供水．而速效P却呈现低于正常供水的趋势。干旱胁追抑制玉米根系生长、减弱根系吸收能力是玉米减产的重要原因。

Shuitu Baochi Xuebao, 2005 三峡库区春玉米盆栽水肥耦合试验研究结果表明，水分胁迫导致玉米株高和叶面积指数降低，以拔节期受到影响最大；玉米产量与生物量呈显著正相关关系，产量与根重无显著正相关关系；水氮耦合效应显著，适宜水分和中氮处理下玉米的产量最高，玉米生长发育对氮肥的吸收存在一定的阈值，过多施用氮肥会加剧土壤干旱和作物干旱，水和钾耦合效应对玉米产量影响不显著；水分是影响玉米产量的主导因素，其次是氮效应和钾效应。
