Use of carrion fly iDNA metabarcoding to monitor invasive and native mammals
Conservation Biology, Volume 37, Issue 5, October 2023., 2023 Abstract Severely fragmented habitats increase the risk of extirpation of native mammal populations through isolation, increased edge effects, and predation. Therefore, monitoring the movement of mammal populations through anthropogenically altered landscapes can inform conservation. We used metabarcoding of invertebrate‐derived DNA (iDNA) from carrion

Taking stock: The contribution of policy studies to our understanding of gun policy
Politics &Policy, Volume 51, Issue 3, Page 415-425, June 2023., 2023 Abstract In the summer of 2022, the tragic mass shooting in Uvalde, Texas once again thrust firearms policy onto the public agenda and opened an agenda window for bipartisan gun reforms in the Senate. Almost simultaneously, the Supreme Court struck down restrictions on concealed carry in New York state in the first major ruling on Second Amendment ...

Global coordination of wheat sowing: A possible policy against climate variability
World Food Policy, Volume 9, Issue 1, Page 6-27, May 2023., 2023 Abstract Through an analysis of the sowing and harvesting times across all the regions of a tailored‐for‐wheat world geographic partition, we assess the temporal possibility of modifying the acreage of wheat crops in some regions in an attempt to offset the change in production caused by the El Niño Southern Oscillation (ENSO) in the others.

Syrian crisis repercussions on the agricultural sector: Case study of wheat, cotton and olives
Regional Science Policy &Practice, Volume 12, Issue 3, Page 519-537, June 2020., 2020 Abstract This paper aims to outline the consequences of the Syrian conflict on the land use/cultivated area, yield and production of the main crops: wheat, cotton, and olives. To achieve the study goal secondary data were collected from FAO website. After that the autoregressive integrated moving average (ARIMA) model was applied for the time series ...

Shuitu Baochi Xuebao, 2020 为给鲁中山区小麦的栽培选育及氮素利用率的提高提供科学依据，连续2年选用鲁中山区栽培面积较广的"泰农18号""临麦4号"和"汶农5号"3个优质小麦品种，设置0，120，240 kg/hm2施氮水平，采用大田试验，研究不同小麦品种的产量及氮素利用效率等对施氮量的响应。结果表明，增施氮肥可以增加小麦叶片光合色素的合成与积累，促进光合作用，提高小麦干物质积累及其向籽粒的转运，有利于小麦群体的构建，促进产量形成，3个小麦品种在N120和N240水平下的产量较N0水平分别增加0.67~2.10，0.97~2.62倍；

Shuitu Baochi Xuebao, 2003 在山西浮山人工模拟建立不同土壤库容系统，对不同库容蓄水供水效应及水分生产效率进行了研究，明确了黄土高原旱地小麦的最佳库容深度(ds)为1．5～2．0m，为黄土高原旱地小麦建立适宜的土壤库容提供了理论依据。1．5～2．0m深的土壤库容改善了小麦全生育期土壤水分状况，特别在小麦需水关键期(拔节期)能最大限度地供给小麦水分，从而有效地增加小麦成穗数及穗粒数。该系统可增产小麦2137．5～2617．5kg／hm^2，增产率高达63．3％～78．7％。
