A more‐than‐human political ecology of Indonesian songbird trade
Conservation Biology, EarlyView.Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...

Gaoya dianqi, 2018 为了分离绝缘纸老化程度和水分对频域介电谱的影响及提高变压器绝缘纸老化程度和水分含量评估精度,文中通过开展加速热老化试验制备了老化程度和含水量均不相同的5组油纸绝缘试样,并对各组试样进行tanδ频谱测试。试验结果表明,在10-310-1Hz频段内,tanδ曲线随绝缘纸老化程度增加而上升;在10-3102Hz频段内tanδ曲线随绝缘纸含水量增大显著上升,在特征频段10-1102Hz和10-310-1Hz内求取tanδ曲线对频率的积分值Sm和SDP分别作为表征水分含量和老化程度的特征量 ...

チューリップ Golden Harvest ノ エダザキ ハッセイ ニ エイキョウ オ オヨボス ヨウイン [PDF]
, 1985 【緒言】チューリップ‘GoldenHarvest\u27は,Multiflowered系統のものを除く他の大多数の品種と同様に,通常1茎に1花しかつけないが,年によって大球では花茎が上部で2～5本に分枝して,それぞれの分校の頂端に花をつける個体がかなり生ずる.この分枝現象は枝咲きといわれ,オランダではみられないが,わが国では問題になっている.枝咲きの発生が夏の涼しいオランダでみられないこと,また,わが国でも発生率が年によりかなり変動することなどから,環境要因とくに夏の高温 ...

Conservation Biology, EarlyView.Abstract Procedural, distributional, recognitional, and epistemic justice aspects of conservation interventions are well documented in contexts where pastoralism is a key livelihood and way of life. Geospatial analyses and representations of wildlife conservation and restoration that are increasingly applied in pastoralist rangeland socioecological ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2004 【目的】探讨体外诱导成人骨髓间质干细胞(humanmesenchymalstemcells,hMSC)向神经元样细胞分化过程中分化与凋亡的关系,为进一步研究延长神经元样细胞的存活时间提供基础。【方法】从成人骨髓分离MSC,培养扩增。以β-巯基乙醇和参芪液诱导分化,于诱导后1、3、5h分别进行免疫组化鉴定神经元烯醇化酶(NSE)、神经丝蛋白(NF)、胶质纤维酸性蛋白(GFAP)的表达,计数神经元样细胞,计算分化率。采用TUNEL方法分别检测诱导后1、3、5h的细胞凋亡率,并分析两者是否相关。【结果 ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature
