Using environmental DNA to inform biodiversity conservation in agricultural landscapes
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2027-08-01

Occupancy dynamics, personality, & behavior of Franklin's Ground Squirrel in agricultural landscapes
… threats to biodiversity worldwide. In fragmented landscapes, movement of organisms among patches of suitable habitat is critical to ecological and evolutionary processes. Movement of organisms allows maintenance of genetic diversity, rescue of declining populations, and recolonization following …

Can annual floral strips create effective pollinator habitat in Southern Ontario agricultural landscapes?
Flower visitors represent a key aspect of biodiversity, providing vital ecosystem services to native flowering plants and commodity crops. Studies indicate a decline in the abundance and diversity of flower visitors worldwide. Recently, Ontario developed a Pollinator Health Action Plan with the …

Process-Based Assessment of Pesticide Fate and Mitigation Strategies in Drained Agricultural Landscapes
… indicate that transport processes in drained agricultural systems remain insufficiently understood. This dissertation aims to improve the understanding of pesticide and TP fate and to assess scenarios for reducing losses using the ecohydrological model SWAT+. The model was applied to a small, …

Improving performance and expanding application of denitrifying bioreactors for nutrient management in agricultural landscapes
… tile drainage is widely implemented across agricultural landscapes in the U.S. Midwest, creating direct hydrologic pathways that transport excess nutrients from fields to surface waters. As a result, nitrate (NO₃) can bypass natural soil filtration and attenuation processes, contributing to …

Ecology of Eastern Wild Turkeys Introduced to Minimally Forested Agricultural Landscapes in Northeastern South Dakota
The ecology of a recently introduced population of eastern wild turkeys (Meleagris gallopavo silvestris) was studied during 1999 and 2000 to determine the adaptability of this subspecies to a minimally forested (<10%) region in northeastern South Dakota. A total of 74 females (53 in 1999 and 21 in …

The population structure and demography of Triturus cristatus in agricultural landscapes of North-West England
… are affected by development. In contrast land in agricultural production covers 71% of the UK but funding for proactive conservation of the species across this habitat is minimal and very difficult to obtain. This thesis has investigated the ecology of T. cristatus on farmland in North West …

Plant communities in field margins of agricultural landscapes: species distributions, functional traits, and contributions to landscape function
Most of the agricultural landscapes are a mosaic of cultivated fields, semi-natural habitats, human infrastructures and occasional natural habitats. Within such landscapes, linear semi-natural habitats often define the edges of agricultural fields, called “field margins”. Field margins are an …

Habitat use, population size, and nesting ecology of conservation priority bird species using restored fields in agricultural landscapes
Agricultural intensification has negatively affected biodiversity throughout the world. In the U.S., population declines of many early successional bird species have been linked with habitat loss due to agriculture. One conservation effort that attempts to mitigate these losses is through programs …

A Physiological Assessment of Wetland Habitats for Spring-migrating Ducks in the Agricultural Landscapes of the Southern Prairie Pothole Region
… the early 1900s. The legacy of ever-increasing agricultural intensity in the southern portions of the PPR, including eastern South Dakota, has left many wetland ecosystems in a matrix of intensive agricultural production. With little surrounding nesting cover, these wetlands are thought to have …

Setting the Baseline for Regeneration of Temperate Native Grassy Ecosystems in Montane Agricultural Landscapes: An Agroecological Approach to Soil Health
… more important than ever. Land use changes for agricultural production significantly contribute to the accelerating rates of land degradation and biodiversity loss in Australia and globally. In response, there has been a shift in agroecological thinking, giving rise to the regenerative …

Role of bats as natural pest control agents of moth pests (false codling moth and carob moth) on citrus orchard
… in the diversity of flora and fauna within agricultural landscapes through intensification of land use. An increase in agricultural intensification has resulted in increased farm sizes and reduced landscape heterogeneity. In the past two decades, the interest in services that insectivorous …

The effects of grassland management practices, and the role of hedgerows, on farmland carbon sequestration and storage
… management decisions, such as those taken in agricultural landscapes, play a crucial role in carbon cycle dynamics with the ability to convert land from a carbon source to carbon sink. Practises influencing carbon sequestration and storage of land are currently missing from inventories of GHG …

Native forest tree conservation in tropical agroforests: Case study of cacao farms in the Atlantic Forest of southern Bahia, Brazil
… systems for ecological conservation in tropical agricultural landscapes because they integrate biodiversity conservation and rural livelihoods. Whether agroforests are long-term solutions for conserving biodiversity in agricultural landscapes may depend sapling regeneration of native forest trees …

Diversity patterns and conservation priorities in the "Mountains of Central Asia" biodiversity hotspot
… and productivity shifts across MoCA identified agricultural land use and climate change as the main drivers of vegetation change, while highlighting the strong influence of orographic heterogeneity. The review also revealed that Kyrgyzstan’s croplands remain poorly studied, despite increasing …
