It is becoming increasingly common to incorporate a system of overpasses,underpasses,culverts,and tunnels along roads and railroads to decrease the barrier effect and restore connectivity of habitats.Systematic monitoring and evaluation of such crossing structures has lagged because of high costs and lack of commitment to adaptive management of roads.Yet,it is clear that wildlife crossing structures have the potential to reconnect fragmented habitat.In an illustrative study,male and female mountain pygmy-possums were separated by a road,and this species of conservation concern suffered declining breeding success.To address this issue,tunnels under the road and habitat corridor leading to the tunnels were constructed to reconnect habitat for males and females,restoring habitat connectivity.Wildlife crossing structures are one way and probably the only effective way of accomplishing this connectivity across roads.
History of Research to Prevent Wildlife Fatalities and Improve Road Permeability
Research on wildlife fatalities on roads has historically focused on ungulates.When large ungulates are hit by vehicles,there are high economic costs and human fatalities.In the United States,annual costs due to ungulate-vehicle collisions were $7.8 million in 1991 and grew to $1.2 billion in 1995.Ungulate fatalities are widely recognized as a problem around the world,especially in the United States and European Union.Because of there issues,documentation of wildlife fatalities and implementation of mitigation techniques initially focused on preventing ungulate crossings instead of restoring habitat connectivity.Current work expands beyond human/economic concerns to addresses other species of conservation concern and,in rare cases,communities of species in attempts to increase road permeability and restore connectivity in the landscape.
楼下两个你们翻译的都不行，你们自己读读看看语句通顺不？拿机器翻的自己也好歹整理修改一下再发上来，不会翻就不要来这丢人好不好

整合公路和铁路沿线的立交桥,地下通道,涵洞,隧道,形成一个系统,由此来减少屏障作用和恢复动物栖息地的连通性.这种情况变得越来越普遍.由于高昂的成本和缺乏对公路的适应性管理,对于这个交叉结构的系统检测和评估仍然滞后.但是,很明显野生动物横穿结构具有重新连接分散的动物栖息地的潜力.在一个说明性研究中,雄性和雌性的高山侏儒负鼠被一条公路分隔后,这一保育物种的繁殖成功率下降.为了应对这一问题,人们建立了隧道和通向这些隧道的栖息地走廊,来重新连接雄性和雌雄高山侏儒负鼠的栖息地,修复栖息地的连接性.野生动物横穿结构是一种,也可能是唯一一种有效的方法来连接公路两边的区域.
防止野生动物死亡,增加公路渗透性的研究历史
对于死于公路上的野生动物的研究历史性地关注了有蹄类动物.当大型有蹄类动物被车撞到时,会引起巨大的经济损失和人员死亡.美国在1991年由有蹄类动物和汽车碰撞造成的损失是780万美元,到了1995年,损失增至12亿美元.有蹄类动物死亡事故是全球都广泛意识到的问题,特别是在美国和欧盟.由于这些问题,野生动物死亡事故的文献和减灾技术的实施首先关注的是防止有蹄类动物穿越马路,而不是恢复栖息地的连通性.目前,企图通过增加道路的渗透性和恢复栖息地的连接性,来解决其他保育物种的问题,或极少数情况下物种群落的问题,这一工作已经超出了人类或者经济的能力范围.
