A Dynamic Principal-Agent Model of Human-Mediated Aquatic Species Invasions AgEcon
MacPherson, Alexander J.; Moore, Rebecca; Provencher, Bill.
This paper presents a dynamic principal-agent model of aquatic species invasions in which a manager, concerned about the spread of invasive species across lakes by boaters, sets interseasonal management controls on a lake-by-lake basis, and boaters make a series of intraseasonal trip decisions to maximize random utility during the course of the season, conditional on the controls imposed by the manager. The results of a simulated invasion of Eurasian watermilfoil (Myriophyllum spicatum) highlight interesting aspects of the optimal management policies under two different management objectives: maximizing boater welfare and minimizing milfoil spread.

A Framework for Spatial Risk Assessments: Potential Impacts of Nonindigenous Invasive Species on Native Species Ecology and Society
Allen, Craig R; USGS Nebraska Cooperative Fish & Wildlife Research Unit, University of Nebraska; allencr@unl.edu; Johnson, Alan R; Clemson University; alanj@clemson.edu; Parris, Leslie; Clemson University; leslie.parris@us.army.mil.
Many populations of wild animals and plants are declining and face increasing threats from habitat fragmentation and loss as well as exposure to stressors ranging from toxicants to diseases to invasive nonindigenous species. We describe and demonstrate a spatially explicit ecological risk assessment that allows for the incorporation of a broad array of information that may influence the distribution of an invasive species, toxicants, or other stressors, and the incorporation of landscape variables that may influence the spread of a species or substances. The first step in our analyses is to develop species models and quantify spatial overlap between stressor and target organisms. Risk is assessed as the product of spatial overlap and a hazard index based...

A Government Decision Model for Invasive Species: Choosing the Most Efficient Government Program for the Management of Livestock Diseases AgEcon
Zhang, Yichen; Muhammad, Andrew; Coble, Keith H..
The impact of invasive species has grown substantially in recent years as evident by the trends in government expenditures in response to outbreaks. In this paper, authors analyze advantages and disadvantages of current government compensation measures for invasive species. The conceptual models are built to describe the relationship between producers’ utility and the effect of adoption of different measures under different observability condition. As a case study, a survey is designed to analyze producer behavior in mitigating AI & END outbreaks.

A massive invasion of fish species after eliminating a natural barrier in the upper rio Paraná basin Neotropical Ichthyology
Júlio Júnior,Horácio Ferreira; Tós,Claudenice Dei; Agostinho,Ângelo Antonio; Pavanelli,Carla Simone.
Based on long-term studies in the upper rio Paraná basin, in addition to a broad review of literature and other information, we were able to identify 33 species of native fishes in the lower rio Paraná basin that successfully colonized the upper rio Paraná after Itaipu impoundment, that flooded the natural geographic barrier constituted by the Sete Quedas Falls. These species belong to six Orders, encompassing two of Myliobatiformes, six of Characiformes, 17 of Siluriformes, six of Gymnotiformes, one of Perciformes, and one of Pleuronectiformes. Extensive remarks regarding each species, including their influence upon the native assemblage, in addition to comments on other non-indigenous species, are also provided. We conclude that, in spite of its...

A morphological reappraisal of the immature stages and life history of Elachista synethes Meyrick (Lepidoptera, Elachistidae), an Australian leaf miner alien to Chile Rev. Bras. entomol.
Vargas,Héctor Andrés; Brito,Rosângela; Basilio,Daniel Silva; Moreira,Gilson Rudinei Pires.
ABSTRACT Elachista synethes was recently recognized as an alien species in northern Chile, where its larvae mine the rescue grass Bromus catharticus (Poaceae). In order to provide the necessary information to allow field detection of E. synethes during early ontogeny, we conducted a morphological reappraisal of the immature stages of this leaf-miner moth, based on light and scanning electron microscopy, including the first descriptions of the egg and the first-instar larva. This is the first report of the existence of an apodal early larva for a species of Elachista Treitschke. The legs and prolegs are absent in the first two instars, but are well developed in the last two. Additional observations on the life history are also provided, including a...

A review of the introduced forest pests in Brazil PAB
Schühli,Guilherme Schnell e; Penteado,Susete Chiarello; Barbosa,Leonardo Rodrigues; Reis Filho,Wilson; Iede,Edson Tadeu.
Abstract: Special attention should be given to forest plantings in order to minimize the probability of exotic pest introduction and, consequently, of production losses. The objective of this review was to present, under a historic perspective, the main exotic insects that harm the Brazilian forest sector. Therefore, to better describe the phytosanitary context of introduced forest pests in Brazil, the main information regarding these insects was gathered here. Introduced species and species with a risk of introduction were listed. The following species were registered: 12 exotic introduced species related to eucalyptus, non-quarantine; 9 species related to pine, one quarantine; and 1 species related to teak, quarantine. Overall, the core problems for 57...

A revision of Jatropha (Euphorbiaceae) in Malesia Naturalis
Welzen, P.C. van; Sweet, F.S.T.; Fernández-Casas, F.J..
Jatropha, a widespread, species rich genus, ranges from the Americas and Caribbean to Africa and India. In Malesia five species occur, all of which were introduced and originated in Central and South America. The five species are revised and an identification key, nomenclature, descriptions, distributions, ecology, vernacular names, uses and notes are provided. Special attention is given to the uses of J. curcas, because it is steadily gaining popularity as a potential biofuel plant and, because of that, is being cultivated more often.

A Sea Change : Exotics In The Eastern Mediterranean OceanDocs
Galil, B.S.; Zenetos, A..
The eastern Mediterranean is susceptible to biological invasions because of its placement between the Atlantic, Pontic and Erythrean regions, busy maritime traffic, and lagoons and bays that are crowded with fish and shellfish farms. However, the greatest influx of invaders resulted from the opening of the Suez Canal in 1869, which allowed entry of Indo-Pacific and Erythrean biota. Exotic macro phytes, invertebrates and fish are found in most coastal habitats in the eastern Mediterranean. Some invaders have outcompeted or replaced native species locally, some are considered pests or cause nuisance, whereas other invaders are of commercial value. However, at variance with other invaded seas, the invasion into the eastern Mediterranean has increased the...

Alien species: economical use, control and impact reduction. Repositório Alice
MARQUES, D. K. S.; SILVA, J. C. B.; OLIVEIRA, M. D. de; MATTHIENSEN, A.; IEDE, E. T.; LISITA, F. O.; GERHARD, P.; SANTOS, S. A.; PENTEADO, S. do R. C.; SALIS, S. M. de; ABREU, U. G. P. de; REIS, V. D. A. dos.
This chapter deals with the contributions of the Brazilian Agricultural Research Corporation (Embrapa) to reach target 15.8 of the Sustainable Development Goals 15 (United Nations, 2018): By 2020, introduce measures to prevent the introduction and significantly reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species. Invasive species are one of the most important environmental challenges in the world. It is not always possible to combat them; generally, complex and expensive proceedings without guaranteed results are necessary. To reduce the impact of alien organisms on the environment, management strategies are used aiming to create mechanisms of environmental resistance.

ALLOCATING BIOSECURITY RESOURCES IN SPACE AND TIME AgEcon
Cacho, Oscar J.; Hester, Susan M..
Invasive species can cause significant damage to natural environments, agricultural systems, human populations and the economy as a whole. Biological invasions are complex dynamic systems which are inherently uncertain and their control involves allocation of surveillance and treatment resources in space and time. A complicating factor is that there are at least two types of surveillance: active and passive. Active surveillance, undertaken by pest control agencies, has high sensitivity but generally low coverage because of its high cost. Passive surveillance, undertaken by the public, has low sensitivity and may have high coverage depending on human population density. Its effectiveness depends on the extent to which information campaigns succeed in...

Analysis of Farm Household Preferences in the Management of Invasive Species: The Case of Miconia in Hawaii AgEcon
Chan-Halbrendt, Catherine; Yang, Fang; Thomas, Lynna; Pant, Archana.
A major threat to Hawaii's ecosystem is the spread of invasive plant species. One such species is Miconia calvescens. Given that this plant was originally introduced to Hawaii by the horticulture industry and has negative effects on agricultural productivity, it is logical to find the farm households' preference for the control of Miconia. Using Conjoint Choice Experiment methodology, this study designed a survey to measure farm households' preferences for Miconia calvescens control program attributes. Results of the surveys indicate that the farm households are willing to support Miconia control programs if they prevent severe soil erosion and loss of biodiversity.

This paper provides an overview of what the Millennium Ecosystem Assessment (MA) calls “indirect and direct drivers” of change in ecosystem services at a global level. The MA definition of a driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. A direct driver unequivocally influences ecosystem processes. An indirect driver operates more diffusely by altering one or more direct drivers. Global driving forces are categorized as demographic, economic, sociopolitical, cultural and religious, scientific and technological, and physical and biological. Drivers in all categories other than physical and biological are considered indirect. Important direct drivers include changes in climate,...

Antispila oinophylla new species (Lepidoptera, Heliozelidae), a new North American grapevine leafminer invading Italian vineyards: taxonomy, DNA barcodes and life cycle Naturalis
Nieukerken, E. van; Wagner, D.; Baldessari, M.; Mazzon, L.; Angeli, G.; Girolami, V.; Duso, C.; Doorenweerd, C..
A grapevine leafminer Antispila oinophylla van Nieukerken & Wagner, sp. n., is described both from eastern North America (type locality: Georgia) and as a new important invader in North Italian vineyards (Trentino and Veneto Region) since 2006. The species is closely related to, and previously confused with A. ampelopsifoliella Chambers, 1874, a species feeding on Virginia creeper Parthenocissus quinquefolia (L.) Planchon., and both are placed in an informal A. ampelopsifoliella group. Wing pattern, genitalia, and DNA barcode data all confirm the conspecificity of native North American populations and Italian populations. COI barcodes differ by only 0–1.23%, indicating that the Italian populations are recently established from eastern North America....

Applying search theory to determine the feasibility of eradicating an invasive population in natural environments AgEcon
Cacho, Oscar J.; Hester, Susan M.; Spring, Daniel.
The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts are incorporated into a population model, and the costs of search and control are calculated as functions of the amount of search effort (the decision variable). Simulations are performed on a set of weed scenarios in a natural environment, involving different combinations of plant longevity, seed longevity and plant fecundity. Results provide preliminary estimates of the cost and duration of eradication programs to assist in prioritising weeds for control. The...

Are native bees and Apis mellifera equally efficient pollinators of the rupestrian grassland daisy Aspilia jolyana (Asteraceae)? Acta Botanica
Maruyama,Pietro K.; Nunes,Carlos E. P.; Vizentin-Bugoni,Jeferson; Gustafsson,Simone; Morellato,Leonor Patricia Cerdeira.
ABSTRACT Most angiosperms rely on animals for pollination, and insects, especially bees, are being the most frequent pollinators. Many native Neotropical plants are frequently visited by the invasive honeybee (Apis mellifera), but its role in the pollination of these plants has been little investigated. We assessed the contribution of various floral visitors, including native bees and the honeybee, on the pollination of a generalist rupestrian grassland daisy, Aspilia jolyana (Asteraceae), in Serra do Cipó, Espinhaço Mountain Range, Brazil. We recorded floral visitors and measured the seed set resulting from one single visitation. We observed a total of 442 visits, mostly by bees, with Bombus pauloensis and Apis mellifera being the most common floral...

Area-Wide Management of Fruit-Flies: What are the Costs and the Benefits? AgEcon
Florec, Veronique; Sadler, Rohan; White, Benedict.
Increasing volumes and speed of agricultural trade and the opening of new markets for agricultural products create greater challenges to systems established to protect countries from invasive organisms that can be harmful to human and animal health, crops and natural environments. In reaction to the threat of exotic pests and diseases, the World Trade Organization recognises the right of country members to protect themselves from the risks posed by exotic pests and diseases through the application of Sanitary and Phytosanitary (SPS) measures. One possible response from exporting countries facing SPS trade barriers is to obtain pest-free area (PFA) certification. While large benefits can potentially be achieved from greater access to world markets through...

Assessment of invasive potential of Homalodisca coagulata in western North America and south America Biota Neotropica
Peterson,A. Townsend; Scachetti-Pereira,Ricardo; Kluza,Daniel A..
The potential of Homalodisca coagulata to invade South America is a question of economic importance, given its potential impact as a disease vector for several crops. We developed ecological niche models for the species on its native geographic distribution in the southeastern United States; we tested the predictivity of the models both on the native distributional area and via projections to California, where the species has long been present as an invasive species. In both cases, tests indicated high statistical significance of predictions. Projection of models to South America indicated little possibility of invasion of southeastern Brazil, where citrus diseases were of concern. However, all models agree in predict-ing great risk of establishment in the...

Bang for the Buck: Cost-Effective Control of Invasive Species with Different Life Histories AgEcon
Buhle, Eric; Margolis, Michael; Ruesink, Jennifer L..
Strategies for controlling invasive species can be aimed at any or all of the stages in the life cycle. In this paper we show how to combine biological data on population dynamics with simple economic data on control cost options to determine the least costly set of strategies that will halt an invasion. We then apply our methods to oyster drills (Ocinebrellus inornatus), an economically important aquaculture pest that has been accidentally introduced worldwide. If the costs of intervention were the same across life stages, extermination of adults would be an inefficient way to control species with the population dynamics characteristics of invaders. In the oyster drill case, however, efficient control targets adults because they are much easier to find.

Behavioral and ecological interactions between reintroduced golden lion tamarins (Leontopithecus rosalia Linnaeus, 1766) and introduced marmosets (Callithrix spp, Linnaeus, 1758) in Brazil's Atlantic Coast forest fragments BABT
Ruiz-Miranda,Carlos Ramon; Affonso,Adriana Gomes; Morais,Marcio Marcelo de; Verona,Carlos Eduardo; Martins,Andreia; Beck,Benjamin B..
Marmosets (Callithrix spp.) have been introduced widely in areas within Rio de Janeiro state assigned for the reintroduction of the endangered golden lion tamarin (Leontopithecus rosalia). The objetives of this study were to estimate the marmoset (CM) population in two fragments with reintroduced golden lion tamarin to quantify the association and characterize the interactions between species. The CM population density (0,09 ind/ha) was higher than that of the golden lion tamarin (0,06 ind/ha). The mean association index between tamarins and marmosets varied among groups and seasons (winter=62% and summer=35%). During the winter, competition resulted in increases in territorial and foraging behavior when associated with marmosets. Evidence of benefits...
