Integrative Conservation, Volume 4, Issue 4, Page 569-583, December 2025.Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Shuitu Baochi Xuebao, 2019 探讨水地条件下种植模式对夏玉米产量及水分利用的影响，为夏玉米节水种植高产稳产栽培提供依据。以玉米品种"登海685"为试验材料，研究宽垄沟播和等行距平播模式下不同种植密度（6.00，6.75，7.50万株/hm2）对夏玉米生长发育、产量、养分吸收及水分利用率的影响。结果表明：沟播种植模式较平播增加玉米植株株高，使茎粗和单株干物质重降低。沟播模式的穗性状比平播处理较优，单穗重增加，且受种植密度影响较小，表现出明显的边行优势。沟播模式的玉米叶片叶绿素相对含量始终高于平播处理，生育期延长 ...

卵泡液白血病抑制因子浓度对IVF-ET妊娠结局的影响 [PDF]
, 2006 【目的】检测卵泡液内白血病抑制因子（LIF）浓度，探讨LIF和体外受精和胚胎移植（IVF-ET）妊娠结局的关系。【方法】接受IVF-ET治疗周期的患者在取卵时留取第1管清亮无血染卵泡液，用酶联免疫吸附法（ELSIA）测定卵泡液内LIF浓度。并对LIF和年龄、性激素、移植胚胎质量以及妊娠率等因素进行分析。【结果】共收集了164个IVF-ET周期（164个病人）的卵泡液。66例妊娠，妊娠率40．2％。卵泡液LIF浓度在妊娠组和未妊娠组间元显著性差别 ...

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2007 【目的】比较两种植骨材料PepGen P15 Flow（简称P15）和Bio-Oss引导即刻种植体周骨组织再生能力及骨一种植体结合能力。【方法】将beagle犬下颌单侧双尖牙全部拔除，然后在新鲜拔牙窝内植入种植体3颗。植入后于种植体颊侧制备标准骨缺损并作如下处置：A组空置，B组植入P15，C组植入Bio-Oss；覆盖Bio-Gide，初期缝合伤口。于术后第6周、12周将beagle犬分期处死获取标本，进行大体、影像学、组织学观测。【结果】B、C组植骨区外形均较A组膨隆，尤其是C组。X线观察可见B ...

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...
