Experimental study designs to improve the evaluation of road mitigation measures for wildlife.

摘要: An experimental approach to road mitigation that maximizes inferential power is essential ensure both ecologically-effective and cost-effective. Here, we set out the need for standards of using an mitigation, in order improve knowledge influence measures on wildlife populations. We point two key areas be considered when conducting experiments. First, researchers get involved at earliest stage or project necessary planning funds are available a high quality experiment. Second, experimentation will generate new about parameters effectiveness, which ultimately allows better prediction future projects. identify seven questions structures (i.e., crossing fencing) remain largely entirely unanswered population-level: (1) Does given structure work? What type size should use? (2) How many build? (3) Is it more effective install small number large-sized large small-sized structures? (4) much barrier fencing needed length road? (5) Do funnel lead animals structures, how long does such have be? (6) manage/manipulate environment area around fencing? (7) Where place provide approaches answering each them example Before-After-Control-Impact (BACI) study designs stages road/mitigation where may become involved: beginning project, after has been constructed; highlighting real case studies available.
