Annotation:

The concepts of evolutionary stable strategies (ESS) and neighborhood invader strategies (NIS) are used to examine the dynamics of coevolving species. When an ESS as well as its near neighbors are ecologically stable and phenotypic space is unconstrained, the strong NIS concept shows that each member of the ESS coalition can always be repelled by some coalition strategies that are sufficiently close to the ESS. Thus an ESS for coevolving species may not be attained by selection unless phenotypic constraints are imposed.

The issue on whether or not poor regions tend to catch-up richer ones plays a significant role in regional growth theory. The empirical growth models were relying more on available data such as real per capita income, savings and investment, government expenditures, exports, labor force and its structure by industries, education variables like school enrollment, etc. The concept of economic convergence according to Matkoski and Prochanik (2004) should be address in two aspects. First, a tendency towards leveling (equalization) per capita incomes and growth rates among counties (regions). Second, tendency toward economic cycle convergence (that is ups and downs of economic cycles ideally should conform). Both convergence concepts are independent and tested separately. In ourresearch we address only first part of the issue, for it is assumed that within boundaries of one country economic cycles should coincide due the equality of macroeconomic conditions.

Annotation:

The important concept of equilibrium has always been controversial in ecology, but a new, more general concept, an asymptotic environmentally determined trajectory (AEDT), overcomes many concerns with equilibrium by realistically incorporating long-term climate change while retaining much of the predictive power of a stable equilibrium. A population or ecological community is predicted to approach its AEDT, which is a function of time reflecting environmental history and biology. The AEDT invokes familiar questions and predictions but in a more realistic context in which consideration of past environments and a future changing profoundly due to human influence becomes possible. Strong applications are also predicted in population genetics, evolution, earth sciences, and economics.

Annotation:

Ecological networks are complex systems forming hierarchical structures in which energy and matter is transferred between the network’s compartments. Predicting energy flows in food webs usually involves complex parameter-rich models. In this thesis, the application of the principle of maximum entropy (MaxEnt) to obtain least biased probability distributions based on prior knowledge is proposed as an alternative to predict the most likely energy flows in food webs from the network topology alone. This approach not only simplifies the characterisation of food web flow patterns based on little empirical knowledge but can also be used to investigate the role of bottom-up and top-down controlling forces in ecosystems resulting from the emergent phenomena based on the complex interactions on the level of species and individuals. The integrative measure of “flow extent”, incorporating both bottom- up and top-down controlling forces on ecosystems, is proposed as a principle behind ecosystem evolution and evaluated against empirical data on food web structure. It could be demonstrated that the method of predicting energy flow with the help of MaxEnt is very flexible, applicable to many different setting and types of questions in ecology, and therefore providing a powerful tool for modelling the energy transfer in ecosystems. Further research has to show in how far the most likely flow patterns are realised in real-word ecosystems. The concept of flow extent maximisation as a selection principle during ecosystem evolution can enhance the understanding of emergent phenomena in complex ecosystems and maybe help to draw a link between thermodynamics and ecology.

Resumo: Nesta tese propomos um desenvolvimento do conceito de especialização no uso de recursos, de forma a incluir aspectos pouco considerados, principalmente no contexto de interações: afinidades entre os tipos de recursos, sua disponibilidade e padrões de coocorrência. Por meio da incorporação de avanços recentes em estudos ecofilogenéticos e em modelos nulos, propomos novas métricas para a especialização de espécies e comunidades, e aplicamos esses avanços para responder a questões particulares. No primeiro capítulo, o arcabouço conceitual é apresentado de forma mais geral, e uma métrica para a especialização de espécies é proposta e exemplificada. O segundo capítulo, de natureza metodológica, estende essa métrica para comunidades e propõe uma partição da variação em especialização entre espécies e entre locais de forma hierarquizada. O terceiro capítulo investiga a capacidade destas ferramentas de evidenciar relações entre a especialização e a distribuição geográfica de espécies de insetos endófagos de capítulos de Asteraceae no Brasil. Por fim, o quarto capítulo utiliza o mesmo conjunto de dados para investigar o papel da diversidade filogenética de recursos na determinação da riqueza de insetos que os utilizam
Abstract: In this thesis we propose a development of the resource specialization concept to include aspects usually not taken into account, especially for trophic interactions: affinities among resource types, their availabilities and cooccurrence patterns with consumers. By incorporating recent advances in ecophylogenetics and null modelling, we propose new metrics for the specialization of species and communities and apply these advances to address particular questions. In the first chapter the general conceptual framework is presented and a metric for the specialization of species is proposed and exemplified. The second chapter, mostly methodological, expands this metric for communities and proposes a hierarchical partitioning of the variation in specialization among species and locations. The third chapter tests this toolset in showing the relationship between specialization and geographic distribution ranges of endophagous insects feeding in Asteraceae flowerheads in Brazil. Finally, the fourth chapter uses the same dataset to investigate the role of phylogenetic diversity of resources in determining the richness of insect herbivores using them

Annotation:

The purpose of this study was to examine the relationship between culture, affordance and proficiency. Further, to study the possibility of a cognitive gap between artists and the audience they design for, akin to the Designer-User gap in interaction design and user experience research. In order to contextualize the issue studied, relevant theories in ecological psychology, visual literacy, image interpretation and cognitive models are presented and discussed alongside contemporary industry issues that may have arisen from this type of cognitive gap. As artist and audience might have these vastly different interpretations of identical visual material, conveying or communicating specific design ideas or aesthetics may be compromised or lost in translation, negatively influencing visual communication. The study compared a set of individuals matching either the label of concept artist or target game audience on their unmediated reactions and mental heuristics when encountering a novel design from a familiar genre, using a method of concurrent verbalization. Results were discussed and compared to prevailing theories in cognition, user experience design and the presented research question. Said results indicate that there are distinct variations between how artists and audience apply their heuristics for unmediated design interpretation, although it also provides a few tentative suggestions as to a few methods in which said issue could be circumvented or surmounted.

The monograph is devoted to the place and role of ecology and environmental safety in ensuring sustainable socio-economic development of society. In the conditions of the forced transition of the economies of the leading countries of the world from an industrial type to a new formation of a green economy aimed at ensuring the preservation of ecological systems and the maximum reduction of damage to the biodiversity of ecological systems, the Russian Federation faces the task of forming a new course of socio-economic development of society focused on the preservation of natural potential and ecology at a level normal for the maintenance of the vital activity of society, flora and fauna in the foreseeable future and in the long term. The role and importance of environmental safety in the system of ensuring the economic security of the state are outlined, the concept of the ideology of "Global Commons" in ensuring sustainable socio-economic development of society is considered, the problems and prospects of the implementation of the program "Green Course of Russia" are analyzed, special aspects of environmental audit, accounting and control, damage assessment in the field of ecology are investigated. Special attention is paid to the forecast of the dynamics of key environmental indicators for the medium term. The main directions of increasing the effectiveness of the mechanism for ensuring environmental safety in a market economy are proposed. For a wide range of readers interested in environmental economics. It will be useful for students, postgraduates and teachers of economic universities.

AbstractRecently, Japan has suffered extraordinary damage from typhoons, heavy rains, and megafloods, each of which has exceeded the upper limit of control by managed infrastructure for flood mitigation. First, I present a conceptual framework of hybrid infrastructure at the watershed scale, combining (1) fundamental green infrastructure (GI), composed of forests and wetlands in the watershed; (2) additional multilevel GI, such as flood control basins; and (3) existing engineered disaster prevention infrastructure, such as dams and artificial levees. Second, I introduce the disaster risk reduction function of natural forests and wetlands and three representative traditional flood control measures: discontinuous levees, overflow embankments, and flood protection forests. This GI should be properly allocated and maintained at the watershed scale to reduce damage by megafloods. The multiple types and functions of GI may provide essential habitats for wildlife and recreational opportunities for local residents and others. Finally, I address key points for planning, implementation, and governance of GI at the watershed scale.

his Rapid Review is an attempt to instigate a broader discussion on child labour by considering the various dimensions and angles associated with the phenomenon beyond the straitjacket definitions provided in most reports. Its objectives are threefold. First, it aims to determine whether re-analysis of existing data sets is likely to yield new insights into the forms, prevalence and drivers of children’s work in agriculture in Ghana. Second, it aims to provide specific guidance on how these re-analyses might be undertaken and framed. And third, it aims to determine whether any of the available data sets might be used to map the number or density of children to the main agro-ecological zones or agricultural systems. In doing this, the review describes the nature of child work in the agricultural sector, highlighting areas that have often been ignored in the literature. The conclusion offers suggestions for future research on child labour based on our renewed understanding of the broad concept of child work.

This report describes the design, implementation and outcomes of the initial version of the NSF-funded Journey to El Yunque curriculum, released in 2005. As formative evaluators, the role of SRI International was to document the development of the curriculum and to collect empirical evidence on the impact of the intervention on student achievement. The evaluation answers four research questions: How well does the Journey to El Yunque curriculum and accompanying assessments align with the National Science Education Standards for content and inquiry? How do teachers rate the effectiveness of the professional development workshop in teaching them to use the Journey to El Yunque curriculum and assessment materials? How do teachers implement the Journey to El Yunque curriculum? To what extent does the Journey to El Yunque curriculum increase students’ understanding ofecology and scientific inquiry abilities? The evaluators concluded that Journey to El Yunque is a well-designed curriculum and assessment replacement unit that addresses important science content and inquiry skills. The curriculum and assessments are aligned to life science content standards and key ecological concepts, and materials cover a broad range of these standards and concepts. Journey to El Yunque students scored significantly higher on the posttest than students learning ecology from traditional means with effect size 0.20.

Although engineered nanomaterials are active components in a wide variety of commercial products, there is still limited information related to the effects of these nanomaterials once released into the terrestrial environment. A high number of commercial applications use silver nanoparticles (nAg) due to its anti-microbial activity. This may be of concern for waste management since nAg could be applied to soil (e.g., biosolids) or disposed of in traditional landfills, which could lead to possible leaching into surrounding soil. This report aims to provide additional insight into the fate and effects of nAg in terrestrial systems. The studies in this report examine the leachability of nAg in field soil and compares the soil migration to bulk (i.e., micron-sized) silver; examine the ecotoxicity of nAg to earthworms in four field soils spanning several different soil orders; and examine the behavioral effects of earthworms when exposed to engineered nanoparticles in field soil. These data provide additional insight into engineered nanoparticle fate and effects to terrestrial receptors in field soils, an important distinction from laboratory-generated soils. These data will also assist ecological risk assessors to better determine the acute environmental risks of nAg in terrestrial ecosystems with different soil compositions.

Mastitis, an inflammatory response of the mammary tissue to invading pathogenic bacteria, is the largest health problem in the dairy industry and is responsible for multibillion dollar economic losses. E. coli are a leading cause of acute mastitis in dairy animals worldwide and certainly in Israel and North America. The species E. coli comprises a highly heterogeneous group of pathogens, some of which are commensal residents of the gut, infecting the mammary gland after contamination of the teat skin from the environment. As compared to other gut microflora, mammary pathogenic E. coli (MPEC) may have undergone evolutionary adaptations that improve their fitness for colonization of the unique and varied environmental niches found within the mammary gland. These niches include competing microbes already present or accompanying the new colonizer, soluble and cellular antimicrobials in milk, and the innate immune response elicited by mammary cells and recruited immune cells. However, to date, no specific virulence factors have been identified in E. coli isolates associated with mastitis. The original overall research objective of this application was to develop a genome-wide, transposon-tagged mutant collection of MPEC strain P4 and to use this technology to identify E. coli genes that are specifically involved in mammary virulence and pathogenicity. In the course of the project we decided to take an alternative genome-wide approach and to use whole genomes bioinformatics analysis. Using genome sequencing and analysis of six MPEC strains, our studies have shown that type VI secretion system (T6SS) gene clusters were present in all these strains. Furthermore, using unbiased screening of MPEC strains for reduced colonization, fitness and virulence in the murine mastitis model, we have identified in MPEC P4-NR a new pathogenicity island (PAI-1) encoding the core components of T6SS and its hallmark effectors Hcp, VgrG and Rhs. Next, we have shown that specific deletions of T6SS genes reduced colonization, fitness and virulence in lactating mouse mammary glands. Our long-term goal is to understand the molecular mechanisms of host-pathogen interactions in the mammary gland and to relate these mechanisms to disease processes and pathogenesis. We have been able to achieve our research objectives to identify E. coli genes that are specifically involved in mammary virulence and pathogenicity. The project elucidated a new basic concept in host pathogen interaction of MPEC, which for the best of our knowledge was never described or investigated before. This research will help us to shed new light on principles behind the infection strategy of MPEC. The new targets now enable prevalence and epidemiology studies of T6SS in field strains of MPEC which might unveil new geographic, management and ecological risk factors. These will contribute to development of new approaches to treat and prevent mastitis by MPEC and perhaps other mammary pathogens. The use of antibiotics in farm animals and specifically to treat mastitis is gradually precluded and thus new treatment and prevention strategies are needed. Effective mastitis vaccines are currently not available, structural components and effectors of T6SS might be new targets for the development of novel vaccines and therapeutics.

Background. Brush encroachment constitutes a serious problem in both Texas and Israel. We addressed the issue of efficacy of livestock herbivory - in the form of goat browsing - to change the ecological balance to the detriment of the shrub vegetation. Shrub consumption by goats is kept low by plant chemical defenses such as tannins and terpenes. Scientists at TAES and ARO have developed an innovative, cost-effective methodology using fecal Near Infrared Spectrometry to elucidate the dietary percentage of targeted, browse species (terpene-richredberry and blueberry juniper in the US, and tannin-rich Pistacialentiscus in Israel) for a large number of animals. The original research objectives of this project were: 1. to clarify the relative preference of goat breeds and the individual variation of goats within breeds, when consuming targeted brush species; 2. to assess the heritability of browse intake and validate the concept of breeding goat lines that exhibit high preference for chemically defended brush, using juniper as a model; 3. to clarify the relative contributions of genetics and learning on the preference for target species; 4. to identify mechanisms that are associated with greater intake of brush from the two target species; 5. to establish when the target species are the most vulnerable to grazing. (Issue no.5 was addressed only partly.) Major conclusions, solutions, achievements: Both the Israel and US scientists put significant efforts into improving and validating the technique of Fecal NIRS for predicting the botanical composition of goat diets. Israeli scientists validated the use of observational data for calibrating fecal NIRS, while US scientists established that calibrations could be used across animals differing in breed and age but that caution should be used in making comparisons between different sexes. These findings are important because the ability to select goat breeds or individuals within a breed for maximal efficiency of brush control is dependent upon accurate measurement of the botanical composition of the diet. In Israel it was found that Damascus goats consume diets more than twice richer in P. lentiscus than Mamber or Boer goats. In the US no differences were found between Angora and Boer cross goats but significant differences were found between individuals within breeds in juniper dietary percentage. In both countries, intervention strategies were found that further increased the consumption of the chemically defended plant. In Israel feeding polyethylene glycol (PEG, MW 4,000) that forms high-affinity complexes with tannins increased P. lentiscus dietary percentage an average of 7 percentage units. In the US feeding a protein supplement, which enhances rates of P450-catalyzed oxidations and therefore the rate of oxidation of monoterpenes, increased juniper consumption 5 percentage units. However, the effects of these interventions were not as large as breed or individual animal effects. Also, in a wide array of competitive tannin-binding assays in Israel with trypsin, salivary proteins did not bind more tannic acid or quebracho tannin than non-specific bovine serum albumin, parotid saliva did not bind more tannins than mixed saliva, no response of tannin-binding was found to levels of dietary tannins, and the breed effect was of minor importance, if any. These fundings strongly suggest that salivary proteins are not the first line of defense from tannin astringency in goats. In the US relatively low values for heritability and repeatability for juniper consumption were found (13% and 30%, respectively), possibly resulting from sampling error or non-genetic transfer of foraging behavior, i.e., social learning. Both alternatives seem to be true as significant variation between sequential observations were noted on the same animal and cross fostering studies conducted in Israel demonstrated that kids raised by Mamber goats showed lower propensity to consume P. lentiscus than counterparts raised by Damascus goats.

The impacts of Harmful Algal Blooms (HAB), often caused by cyanobacteria (Figure 1), on water resources are increasing. Innovative solutions for treatment of HABs and their associated toxins are needed to mitigate these impacts and decrease risks without introducing persistent legacy contaminants that cause collateral ecosystem impacts. This technical note (TN) identifies novel opportunities enabled by Additive Manufacturing (AM), or 3D printing, to produce high surface area advanced material composites to rapidly prototype sustainable environmental solutions for aquatic nuisance species control. This innovative research explores deployment of 3D-printable polymer composite structures containing nano-scale photocatalysts for targeted open water treatment of HABs that are customizable to the site-of-concern and also retrievable, reusable, and sustainable. The approach developed to control cyanobacteria HAB events has the potential to augment or replace broadcast, non-specific chemical controls that otherwise put non-target species and ecological resources at long-term risk. It can also augment existing UV-treatment HAB treatment control measures. The expected research outcome is a novel, effective, and sustainable HAB management tool for the US Army Corps of Engineers (USACE) and resource managers to deploy in their HAB rapid response programs. The research will provide a framework for scale-up into other manufacturing methods (e.g., injection molding) to produce the devices in bulk (quickly and efficiently). Research for this project title “Mitigation of Harmful Algal Bloom Toxins using 3D Printed Photocatalytic Materials (FY21-23)” was sponsored by the US Army Engineer Research Development Center’s (ERDC) Aquatic Nuisance Species Research Program (ANSRP).
