Temporary wetlands are some of the most productive ecosystems available to aquatic and terrestrial organisms. Invertebrates play a critical role in wetlands linking aquatic and terrestrial carbon sources to higher trophic levels such as fish and waterbirds. We assessed the role of large-scale landscape variables (including altitude, longitude and latitude) and wetland size and on the egg-bank structure in 15 wetlands (lagoons) in the North Tableland region of New South Wales. We used microcosms to inundate dry soil from the lagoons and identified the resulting emerged microinvertebrate assemblages. We identified nine microinvertebrate taxa and each lagoon had its own unique microinvertebrate assemblage. The environmental variables did not play a role in determining the assemblages, which emerged from the egg banks of the lagoons, suggesting that each individual lagoon would need to be managed separately for conservation purposes.

景观水平因素对滞育湿地（泻湖）微无脊椎动物丰度和多样性的影响

临时湿地是水生和陆生生物可利用的最具生产力的生态系统之一。无脊椎动物在将水生和陆地碳源与鱼类和水鸟等更高营养水平联系起来的湿地中发挥着关键作用。我们评估了大尺度景观变量（包括海拔、经度和纬度）和湿地大小以及新南威尔士州北部高原地区 15 个湿地（泻湖）的卵库结构的作用。我们使用微观世界来淹没泻湖中的干燥土壤，并确定由此产生的微型无脊椎动物组合。我们确定了九个微型无脊椎动物分类群，每个泻湖都有自己独特的微型无脊椎动物组合。环境变量在确定从泻湖卵库中出现的组合中没有发挥作用，
