On the normative roles of biodiversity and naturalness in conservation. [PDF]

open access: yesConserv Biol
Abstract 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]

open access: yesConserv Biol
Abstract 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

open access: yesWorld 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.

Evaluation of the theoretical risk of cross‐reactivity among recently identified food allergens for dogs

open access: yesVeterinary 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.

河套灌区节水减肥对玉米不同生育期水分和养分的影响

open access: yesShuitu 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,

玉米苗期耐碱性QTL定位分析

open access: yes, 2014
利用郑58/昌7-2构建的156个玉米F2:3家系为作图群体,在100 mmol/L Na2CO3溶液的碱性胁迫下进行玉米苗期耐碱性鉴定,并利用SSR标记构建的分子遗传连锁图谱进行QTL分析。采用复合区间作图法共检测到4个与玉米苗期耐碱率相关的QTL,分布于第2、5、7条染色体上,单个QTL可解释的表型贡献率范围为1.1%~8.6 ...

除草次数对杂草群落和夏玉米产量的影响

open access: yes, 2014
以山东省沂蒙山区夏玉米田为研究对象,设化学除草剂除草(CK)、不除草(W0)、苗期人工锄草1次(W1)、苗期+开花期人工锄草两次(W2)4种处理方式,研究除草次数对农田杂草生物多样性和对夏玉米产量的影响。结果表明,玉米田中9种杂草的多样性指数以W0处理最高,W1处理次之;花后40 dW1、W2处理玉米地上部生物量与CK差异不显著(P0.05)W0处理与CK差异显著(P0.05)产量也表现出相同规律。研究表明,当地苗期适时进行1次除草,不仅能维持杂草多样性,而且可避免作物产量损失;与人工锄草两次相比 ...
