On January 26, 2022 and May 31, 2022, the Province amended the Species at Risk in Ontario List (the SARO List) and made corresponding amendments to O. Reg 242/08, which provides conditional exemptions for specified development activities that impact species included on the SARO List. A ...
They analyzed Southern Ontario data from the citizen science program (该研究小组使用了三个来源的数据。他们分析了来自安大略南部的公民科学项目“大黄蜂观察(Bumble Bee Watch)”的数据)”可知,Colla和她的同事通过分析收集的数据对大黄蜂进行研究。故选C项。【小题4】主旨大意题。根据第一段“The American ...
We placed more emphasis on the ‘At-Risk’ category in this study because COSEWIC prioritizes the assessment of wildlife species thought to be at-risk of extinction. Furthermore, at-risk species represented 73% of all species assessed by COSEWIC (Woo-Durand et al., 2020). The ‘Total DU...
For many alien species, pest risk assessment starts with identifying the potential pest species of concern, the area for which information is needed, possible locations of pest origin, and likely pathways by which the species could enter an uninvaded area (IPPC 2016a). At this stage, ...
21 developed using the ATDN data that comprise our Amazonia dataset. Ter Steege21 et al. found that simulations of sampling of plots with conspecific aggregation from log series-modelled SADs provide extremely good approximations of the processes that generate tropical forest inventory data—that is,...
at the watershed level. Our goal is not only to profile the functional characteristics of non-native established species, but also to quantify the vulnerability of recipient communities based on their functional attributes. We therefore expect that besides the human activities, the invasion risk posed...
To assess the species' potential invasiveness and the likely risks to native species and ecosystems in Europe, available literature from both North America and Europe was reviewed and used to carry out risk screenings of the species for the risk assessment areas, North and South Italy, using ...
Again, as this century closes, it is time to review. 展开 会议名称: Eighth Annual Professional Conference of the Mineral Economics and Management Society, Apr 15-17, 1999, Ottawa, Ontario, Canada 会议地点: Ottawa(CA);Ottawa(CA) 主办单位: 1808 Nedrah Drive Fort Collins, CO 80524 ...
(p = 0.039; Fig.2B). Using this grouping, high-risk species show distinct positions in the life history functional space, with species with lower functional redundancy located around the periphery and likely being more threatened. Only species located at the centre of the functional space ...
