Abstract:
Abstract Halyomorpha halys is an invasive, polyphagous insect that feeds on many major crops, including apple. Statewide monitoring in Minnesota has shown continued increase of H. halys populations and occurrence of this pest in apple orchards. Potential arthropod natural enemies of H. halys and other pests have not been studied in Minnesota apple orchards. The purpose of this study was to characterize the composition of natural enemy communities; compare their abundances, richness and diversities between apple cultivars using different sampling methods; and assess the impact of natural enemie

Abstract:
The importance of plant richness to enhance the presence, biodiversity and efficiency of natural enemies in agricultural systems has largely been studied and demonstrated these last decades. Planting and preserving non-crop plants or manipulating crop richness in fields are practices that have proven their efficiency. However, the impact of crop-richness continuity in space and time on pests and natural enemies at a landscape scale remains poorly studied. In a two-year study, we assessed the effect of crop richness (single crop vs. multiple crops) on pest and natural enemy abundance and spillo

Abstract:
In plant ecology it is common to use biophysical models to predict species distribution; however, spatial quantitative models of plant species remain rare. In practice, occupancy models are often assumed to indicate habitant quality and are used as surrogate abundance models. This study assessed the potential value of quantitative models of plants for ecosystem management applications by assessing patterns of occupancy and abundance within two closely related understorey plant species, Xanthorrhoea australis and X. caespitosa.

Previous research has not specified the puzzling occurrence of the low prevalence of natural resource management (NRM) in intrastate peace- and ceasefire agreements. The purpose of this thesis is to address this gap by applying the theoretical perspectives on high natural resource abundance. High natural resource abundance produces conditions for poor economic management, which may serve as a possible explanation of the low prevalence of NRM. The result of the study indicates a negative correlation between high natural resource abundance and an inclusion of NRM in intrastate peace- and ceasefi

An accurate evaluation of total population density is required in many ecological and biological field. To protect crops from pest attacks, the population density of pests must be evaluated adequately.

In pest monitoring, a classic technique of evaluating density based on a statistical method may result in poor accuracy. Accuracy can be optimised by applying alternative numerical integration methods to the problem. We explain how insuffic

Abstract:
AbstractFishes are among the most diverse and abundant groups of animals in the United Arab Emirates (UAE) and support fisheries that are second most important economic resource in the UAE, after oil. Most fishes are found in the coastal waters, and several species even live in the freshwater pools and streams up in the mountain wadis. Fishes are most abundant in the Gulf of Oman and gradually decline in both abundance and diversity passing through the Strait of Hormuz and towards the southwestern region of the Arabian Gulf, mirroring the increasingly extreme environmental conditions. As fish in the southern Gulf experience extreme environmental conditions, such as high temperatures, that would kill fish from populations elsewhere in the world they are of great scientific value for understanding how fish and their communities might respond to climate change, with studies demonstrating the behavioural and physiological changes that result from these extreme conditions. Fishes in the Emirates are, however, heavily overfished and like fishes elsewhere vulnerable to climate change resulting in Arabian Gulf fish now being vulnerable to local extinction. While fisheries are now being managed to protect vulnerable species, further management is required to protect fish populations for future generations.

Results will be presented for 119-Tin MAS NMR measurements of P2O5-SnO2 glasses. We have found a large change of Tg and phosphorus coordination at different Tin content.

Abstract:
Dousman Creek, located in northeastern Iowa, is a Class ?B? coldwater stream that supports a trout population and is listed among the Outstanding Iowa Waters (Iowa Department of Natural Resources 2010, 2016). The Heartland Inventory and Monitoring Network (Heartland Network) of the National Park Service (NPS) has been monitoring aquatic communities (fish and invertebrates) in Dousman Creek within Effigy Mounds National Monument (NM) since 2008. Corresponding physical habitat and water quality were also collected during biotic sampling. The objectives of this long-term monitoring program are to

Abstract:
Fossil Point is an exceptionally rich and scientifically important fossil locality found in Lake Clark National Park and Preserve. The rocks at Fossil Point are known for their abundant and well-preserved Middle Jurassic invertebrate fossils, including bivalves, ammonites, and belemnites. The abundance and quality, as well as the relatively easy coastal access, makes the fossils at Fossil Point vulnerable to unauthorized collection. Anecdotal evidence suggests that collection without a permit is occurring at Fossil Point and has been for decades. Monitoring of the prevalence and scale of unaut

Abstract:
The National Park Service (NPS) Water Resources Division’s Natural Resource Condition Assessment (NRCA) Program initiated an NRCA project with Fort Pulaski National Monument (FOPU) in 2022. The purpose of an NRCA is to synthesize information related to the primary drivers and stressors affecting natural resource conditions at a park and to report conditions for natural resource topics selected by park managers. Resource conditions are evaluated as either a condition assessment or a gap analysis, depending on data availability. For FOPU’s NRCA, managers selected salt marsh, shorebirds, Eastern

Abstract:
The abundance of natural resources can adversely affect the macroeconomic stability of countries. Developing economic institutions that support the proper management of extractive industry resources is one of the fundamental factors for maintaining macroeconomic stability and generating long-term economic growth. This paper evaluates the impact of terms-of-trade shocks on fiscal performance and economic growth in the countries of the Andean region. To adequately capture the variation in both the magnitude of shocks and the sensitivity of economic and fiscal variables to those shocks, this pape

Abstract:
Problematic species, which include invasive, exotic, and harmful species, fragment native ecosystems, displace native plants and animals, and alter ecosystem function. In National Parks, such species negatively affect park resources and visitor enjoyment by altering landscapes and fire regimes, reducing native plant and animal habitat, and increasing trail maintenance needs. Recognizing these challenges, Heartland Inventory and Monitoring (I&amp;M) Network parks identified problematic plants as the highest-ranking vital sign across the network. Given the need to provide early detection of pote

Abstract:
Channel Islands National Park includes the five northern islands off the coast of southern California (San Miguel, Santa Rosa, Santa Cruz, Anacapa, and Santa Barbara Islands) and the surrounding waters out one nautical mile. There are approximately 176 miles of coastline around the islands, about 80% of which is composed of rock. The diversity and undisturbed nature of the tidepools of this rocky coastline were recognized as special features of the islands in the enabling legislation. To conserve these communities unimpaired for future generations, the National Park Service has been monitoring
