“…Swainson's hawks are particularly susceptible to insecticides because they forage for large numbers of insects during insect outbreaks. Their susceptibility was discovered first relative to the use of organochlorides, but they are also vulnerable to other pesticides (Shaffer et al 2019). Similarly, carbaryl and carbofuran, two insecticides used to control agricultural pests in corn and alfalfa fields, were found to decrease reproductive success of Burrowing Owls (Athene cunicularia hypugaea) when sprayed in proximity (50-400 m) to their burrows (Shaffer et al 2022).…”

Insects serve as ecosystem engineers in grasslands. Their impacts are comparable in scale to those of mammals, but because they are so much smaller, their roles and influences are not always as obvious. The roles that insects play in grasslands are as diverse as Class Insecta itself, including herbivory, pollination, seed dispersal, soil profile modification, nutrient cycling, parasitism, and serving as intermediaries between plants and wildlife in food webs. In the context of their effects on grassland wildlife species, insects serve as essential food resources for many species of birds, bats, reptiles, mammals, amphibians, fish, and other insects. Insects also have significant effects on the habitat structure available for wildlife because they can, on the one hand, enhance the productivity of grassland vegetation, but alternatively, they have the power to completely defoliate a grassland. From the perspective of food webs, insects play multiple roles. They can serve as food for wildlife, but they also can serve as parasites, vectors of disease, and decomposers. Ecological changes in grasslands due to events such as fire, grazing, herbicide or insecticide application, and habitat fragmentation or loss can affect both wildlife and insects. For that reason, ecologists are often interested in linking the study of a particular wildlife species to the associated insect community. Insects are simply less visible ecological engineers, continually interacting with wildlife, and modifying the habitat where they coexist with wildlife in grassland ecosystems.

The ACBK is seeking ways to learn about the effects of renewableenergy developments on biodiversity and desires to spread that knowledge to other interested agencies and industries within Kazakhstan. Jill Shaffer and Todd Katzner (USGS Forest and Rangeland Ecosystems Science Center), another Fellow, visited Kazakhstan from September 17 to October 1, 2023. They met with U.S. Embassy officials in the divisions of Economics and in Environment, Science, Technology, and Health and with ACBK biologists. They also gave two presentations that described an eight-part virtual lecture series they developed to help Central Asians understand the effects of wind energy on biodiversity. The lecture series was presented monthly through March 2024. The recorded lectures, the pre-lecture readings, and post-lecture source material can be accessed from the ACBK website at https://www.acbk.kz/ article/ default/ view/ 635. While in Kazakhstan, Jill and Todd also presented on the effects of wind-energy on golden eagles (Aquila chrysaetos) at the "Eagles of the Palearctic Conference" in Almaty. They participated in bird-banding activities using Heligoland traps at Chokpak Ornithological Station in the village of Chokpak.
