Available in PDF, EPUB and Kindle. Book excerpt: Invasive species have major impacts on the ecosystems they invade. Among the most disruptive groups of invasive species are ants. Invasive ants have caused losses in biodiversity among a wide range of taxa, including birds, mammals, lizards, but especially towards ground nesting arthropods such as native ants. Why native ants are so susceptible to invasion and how invasive ants are able to sustain massive population growth remain unclear. It has been suggested that invasive ants utilize carbohydrate resources from hemipteran exudates to fuel aggressive foraging and colony expansion. Perhaps invasive ants are simply more proficient at usurping these resources, maintaining higher hemipteran populations, etc. Our work uses a model invasive, the Argentine ant, Linepithema humile, and a native ant Tapinoma sessile to quantify hemipteran tending ability and competition. Through a series of laboratory and field experiments we were able to quantify 1) carbohydrate sequestering performance, 2) the effect either ant species had on hemipteran population growth rates in a predator-free space, 3) the defense ability of either ant against hemipteran predators and parasitoids, and 4) the proportion of invasive ants required to displace a native colony from a hemipteran resource. Neither ant demonstrated a better ability to sequester liquid resources; however recruitment strategies were much different. Hemipteran populations in the presence of L. humile grew larger in a predator free environment and populations exposed to predators were better defended by L. humile than T. sessile. L. humile was able to displace T. sessile from a nest site without having a majority of worker ants. Aggression of either ant species was significantly reduced without hemipterans present. Understanding factors that drive invasive species can give us insight into native areas that may be susceptible for invasion, how potential mutualist populations might respond and possibly provide us with an avenue f.

Menke and published by . This book was released on 2007 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: A prominent and unresolved question in ecology concerns why communities differ in their susceptibility to invasion. A complete knowledge of this issue will only result from an understanding of how biotic interactions and abiotic suitability interact with one another and change in importance across spatial scales. Factors important in determining the spread of invasive species at the community scale, such as local environmental conditions and biotic resistance, may be completely different from the factors that determine occurrence at the regional or global scale.

Available in PDF, EPUB and Kindle. Book excerpt: Urbanization creates novel environments that constrain the availability of natural resources, like food, which can often be a limiting factor in determining where species may establish and survive. Compared to natural habitats that have supported native fauna for hundreds of years, urban areas provide novel habitats and food sources that native species may not be able to exploit. Instead, we see the proliferation of invasive species in these areas, because they can adapt and survive on a wide variety of food sources that most native species cannot. One species of concern is the Argentine ant (Linepithema humile), an invasive species that has been able to out compete native ants throughout the world, by displaying plastic responses to novel environments. Yet, little is understood about how urbanization affects behaviors such as food preference, which may be disproportionately supporting invasive species in urban landscapes. To determine food preference in the Argentine ant, I examined the differences in food preference between two invasive populations of Argentine ants - from natural and from urban environments. Because these two habitat types provide divergent food sources, we may be able to uncover how urban areas skew food availability and affect preference in invasive species.

This book was released on 2015 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Argentine ant (Linepithema humile) is a widespread invasive species whose spread has been largely linked to abiotic variables. I documented the distribution of L. humile with respect to an urban edge and riparian corridor at two sites in southern California. I attempted to link their distributions to relative humidity, temperature, and soil moisture; variables often cited as possible predictors of invasion. I also tested for associations between L. humile and other ant species. I studied the interplay between soil moisture and humidity levels in Argentine ant survival and reproduction in a laboratory experiment. Argentine ants were more abundant near the urban and riparian interface as predicted, although this relationship was not consistent. Temperature, relative humidity or soil moisture did not correlate with their distributions. Contrary to expectations, the majority of ant species were independently distributed with respect to L. humile. In the laboratory, L. humile worker survival was greater in humid habitats with ample soil moisture as compared to dry conditions. More eggs were laid in humid habitats than dry indicating an increase in reproduction under high humidity.

This book was released on 2012-12-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diversity of the earth's climates superimposed upon a complex configuration of physical features has provided the conditions for the evolution of a remarkable array of living things which are linked together into complex ecosystems. The kinds of organisms comprising the ecosystems of the world, and the nature of their interactions, have constantly changed through time due to coevolutionary interactions along with the effects of a continually changing physical environ ment. In recent evolutionary time there has been a dramatic and ever-accelerating rate of change in the configuration of these ecosystems because of the increasing influence of human beings. These changes range from subtle modifications caused by anthropogenically induced alterations in atmospheric properties to the total destruction of ecosystems. Many of these modifications have provided the fuel, food, and fiber which have allowed the expansion of human populations. Unfortunately, there have been many unanticipated changes which accompanied these modifications which have had effects detrimental to human welfare in cluding substantial changes in water and air quality. For example, the use of high-sulfur coal to produce energy in parts of North America is altering the properties of freshwater lakes and forests because of acidification.

Book excerpt: In this study we investigate the effects of the invasive Argentine ant (Linepithema humile) on the food-for-protection mutualism between native ant species and the San Diego Barrel Cactus (Ferocactus viridescens). Mutualistic interactions may be disrupted by non-native species with possible detrimental effects for one or both partners. In the presence of L. humile, plant protection may be enhanced in the short term as a consequence of the Argentine ant's aggressive nature, yet may be compromised by pollinator harassment and abandonment of the cactus. Consequently, in the long term, this invasion may decrease the fitness of cacti by shifting the net effects of the interaction from a mutualism to one that is detrimental. To quantify ant protection, we used an established surrogate herbivore assay to compare protective services offered by Argentine ants with those offered by a common native ant C. californica. Our results support the existence of a mutualism between ants and F. viridescens. Ant presence discouraged leaf-footed bugs, the most commonly observed herbivores, from feeding on plant reproductive structures. Herbivory reduced mass per individual seed and seed mass per plant. This study adds to a growing body of work concerning the variation found in mutualistic interactions, allows for predictive measures of plant benefits with respect to partner identity, and examines how these interactions are affected by a behaviorally dominant and aggressive invasive ant. Furthermore, it explores the consequences of reduced ant richness, and the impacts that result from the loss of functional redundancy in the F. viridescens food-for-protection mutualism.
