Conservation Biology, Volume 36, Issue 5, October 2022., 2022 Abstract As agricultural land use and climate change continue to pose increasing threats to biodiversity in sub‐Saharan Africa, efforts are being made to identify areas where trade‐offs between future agricultural development and terrestrial biodiversity conservation are expected to be greatest. However, little research so far has focused on freshwater

Evaluating the social and ecological effectiveness of partially protected marine areas
Conservation Biology, Volume 35, Issue 3, Page 921-932, June 2021., 2021 Abstract Marine protected areas (MPAs) are a primary tool for the stewardship, conservation, and restoration of marine ecosystems, yet 69% of global MPAs are only partially protected (i.e., are open to some form of fishing). Although fully protected areas have well‐documented outcomes, including increased fish diversity and biomass, the effectiveness ...

Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes
Journal of Eukaryotic Microbiology, Volume 66, Issue 1, Page 4-119, January/February 2019., 2019 Abstract This revision of the classification of eukaryotes follows that of Adl et al., 2012 [J. Euk. Microbiol. 59(5)] and retains an emphasis on protists. Changes since have improved the resolution of many nodes in phylogenetic analyses. For some clades even families are being clearly resolved.

Quantifying progress toward a conservation assessment for all plants
Conservation Biology, Volume 32, Issue 3, Page 516-524, June 2018., 2018 Abstract The Global Strategy for Plant Conservation (GSPC) set an ambitious target to achieve a conservation assessment for all known plant species by 2020. We consolidated digitally available plant conservation assessments and reconciled their scientific names and assessment status to predefined standards to provide a quantitative measure of progress ...

Effects of protection and temperature variation on temporal stability in a marine reserve network
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Understanding the drivers of ecosystem stability has been a key focus of modern ecology as the impacts of the Anthropocene become more prevalent and extreme. Marine protected areas (MPAs) are tools used globally to promote biodiversity and mediate anthropogenic impacts.

Global status, impacts, and management of rocky temperate mesophotic ecosystems
Conservation Biology, Volume 38, Issue 1, February 2024.Abstract The ecology and function of rocky temperate mesophotic ecosystems (TMEs) remain poorly understood globally despite their widespread distribution. They typically occur at 20–150 m (the limit of photosynthesis), and on rocky substratum they support rich benthic communities and mobile fauna.

Gongye shui chuli, 2011 考察了高锰酸盐预氧化—生物活性炭联用工艺去除藻类的效能。试验结果表明,高锰酸盐预氧化能明显改善混凝工艺对藻类的去除效果,随高锰酸盐投量的增加,混凝工艺对藻类的去除率呈上升趋势。生物活性炭滤池对藻类的去除主要集中在进水端,在20 cm处,去除率可达到60%。高锰酸盐—生物活性炭联用工艺对藻类及有机物有明显的去除,去除率可分别达到99.5%和20.6%。

Shuitu Baochi Xuebao, 2007 以淮南市潘三塘为例,探讨了浅水塌陷塘新型湿地的藻类群落季节特征及其对生境的响应.结果表明,水塘夏季水体有机污染严重(CODCr为52.63 mg/L),营养盐(TP、TN)为Ⅴ类水质,分别达0.45 mg/L,2.01 mg/L,营养状况为重度富营养化,其藻类以蓝藻为优势种;春秋季水体污染稍弱于夏季,属Ⅳ类水质,为中度富营养化,秋季(藻类优势种为绿藻)富营养化程度略高于春季,总体水平接近重度富营养化.藻类生物量Chla秋季最高(27.54 mg/m3),夏季次之(16.85 mg/m3),春季最低(5 ...

四川大学学报. 自然科学版, 2002 以矿石磷为唯一磷源 ,培养 3种藻类植物 ,应用钼蓝比色法测定 3种藻类从矿石磷中转化释放出来进入培养基的有效磷 ,应用灼烧法测定 3种藻类生物量 .分别以培养基的有效磷浓度和单位干重藻体所释放出来的有效磷量来表示他们的转化利用程度 ,结果表明 ,3种藻类植物都具有转化利用释放磷的作用 .但沙角衣藻较颤藻和栅藻的作用更强 ,能以较少的生物量释放出更多的有效磷 ,有较大的实用价值 .
