Understanding the factors that contribute to population stability in long-distance migrant birds is increasingly important, particularly given global cli.a.e change, sea level rise, and loss or disturbance at essential habi.a.s. While the populations of most shorebirds are declining worldwide, those that migrate through Delaware Bay, New Jersey and Delaware, are declining at the most rapid rate despite conservation efforts. in this paper, we 1) provide background information on population declines of red knots (Calidris canutus rufa) using Delaware Bay, threats to their foraging, and efforts to reduce threats, 2) summarize briefly our studies of the effects of human activities on knots and other shorebirds, 3) present data on management efforts to protect knots and other shorebirds from the activities of people, and 4) discuss the effi.a.y of such efforts (usually referred to as “decreasing the effect of human disturbances”). The Shorebird Project on Delaware Bay is over 25 years old and provides long-term data to help assess the status of shorebird numbers, particularly for red knot, as well as the density of horseshoe crabs (Limulus polyphemus) and their eggs. Red knots have continued to decline even more precipitously in the last few years, presenting cause for concern. Protective efforts have been successful in reducing human disruption on the N.J. Delaware Bay beaches, but the lack of uniformity in implementation across the New Jersey side, and across the whole Bay have hampered further improvements. implementation of signs, fencing, and stewards on some beaches signifi.a.tly enhanced the use of these beaches by red knots, determined by examining the use of beaches pre- and post-implementation. implementation of fencing and stewards had the greatest effect. From 1986 to 2018, there was a signifi.a.t shift in the percent of Delaware Bay red knots using the NJ side, where protection efforts had been implemented on many of the beaches.

The response of insects to monoculture plantations has mainly proceeded at the expense of natural forest areas, and is an outstanding and important issue in ecology and conservation biology, with polli.a.ion services declined around the world. in this study, species richness and distribution of hoverfly and wild bee communities were investi.a.ed in a changing tropi.a. landscape in southern Yunnan, south-west Chi.a.by Malaise traps periodi.a.ly from 2008 to 2009. Species were recorded from the traditional land use types （natural forest, grassland, shrubland and rice field fallows）, and from recently established rubber plantations of different ages. Hoverflies （total 53 species） were most common in young successional stages of vegetation, including rice field fallow and shrubland. Species richness was highest in rice field fallows and lowest in forests and showed a highly signifi.a.t relationship with the number of forb species and ground vegetation cover. in contrast, the highest richness of wild bees （total 44 species） was recorded from the natural forest sites, which showed a discrete bee community composition compared to the remaining habi.a. types. There was no signifi.a.t relationship between the bee species richness and the environmental variables, including the numbers of different plant life forms, coverage of canopy and ground vegetation, successional age of vegetation and land use type. At the landscape scale, open land use systems, including young rubber plantations, are assumed to increase the species richness of hoverflies; however, this might decrease wild bee diversity. The present land use change by rubber culti.a.ion can be expected to have negative impacts on the native wild bee communities.
