I investigated parasitic infection and immunocompetence in populations of introduced bird species in New Zealand (NZ) that had experienced a range of population bottlenecks (11-808 individuals), and compared these parameters to non-bottlenecked conspecifics in the United Kingdom (UK). My aims were two-fold; firstly to assess if population bottlenecks are linked to increased parasite loads and/or decreased immunocompetence, and secondly, to assess at what severity of bottleneck these effects become evident. I found that ectoparasite load (chewing lice, Order: Phthiraptera, Sub-Orders: Amblyce

Cervids are a widespread family of ungulates, native to the Americas, Europe and Asia and introduced to Australia. Densities of cervids have increased in North America, Europe and Japan during the last couple of decades, due to changes in land use, reduced hunting, lack of large carnivores and changes in management practices. Where they occur at high densities, native and introduced cervids may have profound effects on vegetation, causing knock-on effects on other taxa. Cervids are in some instances managed towards changing the local distribution through supplemental feeding. These supplementa

It is generally accepted that populations which experience severe bottlenecks have a reduction in fitness. One of the most frequently reported fitness costs is increased hatching failure in bottlenecked populations of birds. The mechanism responsible for increased hatching failure is unknown. Research on other animals suggest that reduced population numbers cause unavoidable inbreeding that in turn leads to abnormalities in the gametes. In this thesis I examine some of the possible causes for increased hatching failure in severely bottlenecked populations of introduced birds in New Zealand. I

Species translocations result in demographic bottlenecks that may produce inbreeding depression and reduce genetic variation through random sampling and drift, an outcome that could decrease long-term fitness and adaptive potential of many New Zealand species. Despite considerable evidence for costs associated with inbreeding and reduced genetic variation, some species have recovered from a small number of individuals and are thriving, perhaps via high growth rates, differential survival of heterozygous individuals or inbreeding avoidance.

Одно из направлений экологизации экономического развития - это широкое развитие малоотходных и ресурсосберегающих технологий. Разработанный автором (в соавторстве) технологический комплекс по утилизации птичьего помета (установка пневмотермической сушики - УПС-1 и установка термического компостирования) был применен на птицефабриках Пермского края. Полученный на УПС-1 сушеный птичий помет (СПП) и гранулированный (ГСПП), в серии полевых опытов вносился, в качестве удобрения, на поля Пермского края и Ленинградской области.

The construction industry increasingly demands efficient, cost-effective, and customizable project delivery, yet existing digital integration through Building Information Modeling (BIM) encounters challenges, particularly in achieving seamless cross-department and multi-platform collaboration. Addressing these challenges, this research introduces a Building Information Relational Database (BIRD) aimed at enhancing data interoperability and supporting tailored project delivery for general contractors. Despite the advantages of BIM, general contractor and design-build firms face persistent commu

In 2021, landbird surveys were conducted at Kalaupapa National Historical Park on the island of Molokaʻi to assess changes in species composition, distribution, and population densities since 2005. Point-transect distance sampling surveys were conducted on six transects at 50 landbird monitoring stations within an 1,834-hectare area. A total of nine landbird species were detected, with the ʻApapane (Himatione sanguinea) the only endemic Hawaiian species detected. Sufficient detections of six species allowed for population density and abundance estimates, which were compared to 2005 estimates u

The avian influenza virus, subtype H9N2 subtype, defined as having a low pathogenicity, causes extensive economical losses in commercial flocks, probably due to management and synergism with other pathogens. AIV H9N2 was first identified in Israel in the year 2000, and since then it became endemic and widespread in Israel. Control by vaccination of commercial flocks with an inactivated vaccine has been introduced since 2007. In face of the continuous H9N2 outbreaks, and the application of the vaccination policy, we aimed in the present study to provide a method of differentiating naturally inf

We investigate the effects of a change in the regulation of the spot market for electricity in Colombia that took place in 2009. Specifically, the regulation switched from an auction mechanism with simple bids to one with complex bids to allow generators to separately bid on variable and quasi-fixed components. This greater flexibility was introduced to reduce production inefficiencies that arise from non-convexities in the cost structures of thermal generators. In this paper, we estimate and compute a structural model to quantify the effects of this change on allocation efficiency along with

We present a deep learning solution to address the challenges of simulating realistic synthetic first-price sealed-bid auction data. The complexities encountered in this type of auction data include high-cardinality discrete feature spaces and a multilevel structure arising from multiple bids associated with a single auction instance. Our methodology combines deep generative modeling (DGM) with an artificial learner that predicts the conditional bid distribution based on auction characteristics, contributing to advancements in simulation-based research. This approach lays the groundwork for cr

Mute swans (Cygnus olor) are an invasive species originally brought to the United States in the late 19th and early 20th centuries for ornamental ponds and lakes, zoos and aviculture collections. Original populations were located in northeastern states along the Hudson Valley but have since expanded to several Midwestern states and portions of the western U.S. and Canada. Mute swan damage includes competing with native waterfowl, destroying native plants, spreading disease, and colliding with aircraft. They are also considered a nuisance in some areas due to their abundant fecal droppings and

Climate change and habitat loss are two intersecting issues facing communities and ecosystems in British Columbia’s Lower Mainland. In response to increasingly severe weather, municipalities have invested heavily in engineered defences like floodgates, dikes, and breakwalls, resulting in a profound loss of aquatic and riparian habitat. These lost ecosystems were once critical to local wildlife and provided water management services like flood mitigation and water filtration. Nature-based Solutions offer a unique opportunity to simultaneously address heightened climate risks and habitat loss by

This paper discusses privatization among investments in infrastructure. The goal of this paper is to present a new auction mechanism that solves many of the problems that have hindered the use of franchises. The first section of the paper discusses least present value of revenue (LPVR) auctions, where the regulator fixes user fees (according to some optimizing criterion) and asks for bids on the present value of revenue from user fees that franchise holders will accept in exchange for building, operating and maintaining the infrastructure.

In this paper we have investigated effects of GHG mitigation policies on livestock sectors. We used a global computable general equilibrium GTAP-AEZ-GHG model with explicit unique regional land types, land uses and related GHG emissions. The model is then augmented with cost and GHG response information from partial equilibrium approaches to abatement of land-based greenhouse gas emissions. With this framework we analyze changes in regional livestock output, sector competitiveness and regional food consumption under different climate change mitigation policy regimes.
