Book excerpt: Ants are familiar to every naturalist, ecologist, entomologist, and pest control operator. The identification of the 233 species of Florida ants is technically difficult, and information on Florida ants is dispersed among hundreds of technical journal articles. This book uses detailed and beautiful scientific drawings for convenient identification. To most Florida biologists ants are currently the most inaccessible group of conspicuous and intrusive insects. This book solves the twin problems of ant identification and the extraordinary fragmentation of natural history information about Florida ants.

This book was released on 2015 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social insects rank among the most ubiquitous and ecologically dominant terrestrial animals on Earth. Complex communication and social organization are two defining features of social insect societies and ants, in particular, have evolved extensive systems of chemical communication. In both natural and agricultural systems, including coffee agroecosystems, ants are important predators and often have strong and complex effects on pest species. In this dissertation, I explore how chemical communication plays a role in dynamics between ants and their natural enemies within these coffee agroecosystems, to gain a better understanding of both how ants utilize their own chemical communication systems and how natural enemies of ants take advantage of these systems to exploit ants. In the first dissertation chapter, I review the literature on chemical and visual cues that one natural enemy of the ant, the phorid fly, uses to successfully parasitized its host ants. Phorid fly parasitoids that use ants as hosts often require the use of multiple cues, ranging from general to highly specific, to home in on an ideal host. Here I outline the five common steps in which phorid flies use cues: (a) host habitat location, (b) host location, (c) host acceptance, (d) host discrimination and (e) host regulation. I then discuss our current understanding of how phorid flies use each of these steps to successfully parasitize ant hosts. Finally, I examine the wide variety of strategies and cues used by a multiple species of phorid flies within three separate genera (Apocephalus, Pseudacteon, and Neodohrniphora) and discuss future directions within this field of study. In the second dissertation chapter, I investigate the role of Azteca ant cuticular hydrocarbon cues as a short-range cue for a suite of Pseudacteon spp. phorid fly parasitoids commonly found within coffee agroecosystems. Here I describe the hierarchy of cues Pseudacteon spp. phorid flies use to successfully identify Azteca host ants. I use behavioral observations in the field to show phorid flies are attracted to two cryptic Azteca taxa, but will only attack Azteca sericeasur (Hymenoptera: Formicidae: Dolichoderinae). To test whether the phorid flies are able to distinguish between the two Azteca taxa using their cuticular hydrocarbons, I first document and compare the cuticular hydrocarbons of two cryptic Azteca taxa using gas chromatography-mass spectrometry (GC/MS). Using cuticular hydrocarbon transfer experiments with live ants from both Azteca taxa, I identify the cuticular hydrocarbons of Azteca sericeasur as a short-range host location cue used by Pseudacteon lasciniosus (Diptera: Phoridae) to locate the ants. In the third chapter, I describe two new species of Myrmedonota (Coleoptera: Staphylinidae) that are also natural enemies of Azteca sericeasur ants. Here I record this genus of beetle in Mexico for the first time, and describe M. xipe and M. shimmerale for the first time. This chapter also documents that both Myrmedonota species will aggregate towards agitated ants, to prey on Azteca sericeasur and these species will form mating swarms, either with no apparent landmark or in the vicinity of ants. My fourth chapter examines the role of the beetle, Myrmedonota xipe, in Azteca ant-phorid fly interactions. Here I use pheromone bioassays to show that M. xipe is attracted to a component of A. sericeasur alarm pheromone. In the field experiments, I determine that the beetles are able to locate parasitized ants as prey items but not healthy ants. In choice tests in the lab, I also show that beetles will preferentially attack parasitized ants over healthy ants. Analysis of the choice tests also indicates that the aggression in parasitized ants is so reduced that beetles are essentially able to eat these ants alive without interruption. These results suggest that, although beetles are predators of the ants, by preying primarily on ants harboring phorid fly eggs, the beetles may also provide indirect positive effects for the ant colonies as a whole. In my final dissertation chapter I examine the variation in cuticular hydrocarbon blends of three species of arboreal twig nesting ants, Pseudomyrmex simplex, Pseudomyrmex ejectus and another Pseudomyrmex sp. (referred to as PSW-53) commonly found within the coffee agroecosystems of Southern Mexico. In this study, I examined whether variation in the ecology and social structure of these species is reflected in the variation in their cuticular hydrocarbon profiles. I tested the hypothesis that the more abundant species with higher nest densities exhibit lower cuticular hydrocarbon variation. The results showed that worker ants of abundant P. ejectus and P. simplex from the study site exhibit significantly lower variation in cuticular hydrocarbon profiles than workers of the rare ant species P. PSW-53. Our study reinforces the idea that examining cuticular hydrocarbon profiles can provide insight into the colony structure of social insects. Overall, the results from my dissertation provide insight into the complex interactions between ants and their natural enemies, particularly shedding light on how these interactions are facilitated through the use of ant pheromones as cues and signals. The ants and their natural enemies that I focus on in my dissertation are also important players within the greater coffee agroecosystems in which they inhabit, and this body of work is thus critical for understanding how their network of interactions involving ants and their natural enemies may impact coffee pest control.

Available in PDF, EPUB and Kindle. Book excerpt: The world relies on very few crop and animal species for agriculture and to supply its food needs. In recent decades, there has been increased appreciation of the risk this implies for food security and quality, especially in times of environmental change. As a result, agricultural biodiversity has moved to the top of research and policy agendas. This Handbook presents a comprehensive overview of our current knowledge of agricultural biodiversity in a series of specially commissioned chapters. It draws on multiple disciplines including plant and animal genetics, ecology, crop and animal science, food studies and nutrition, as well as social science subjects which explore the socio-economic, cultural, institutional, legal and policy aspects of agricultural biodiversity. It focuses not only on the core requirements to deliver a sustainable agriculture and food supply, but also highlights the additional ecosystem services provided by a diverse and resilient agricultural landscape and farming practices. The book provides an indispensable reference textbook for a wide range of courses in agriculture, ecology, biodiversity conservation and environmental studies.

Available in PDF, EPUB and Kindle. Book excerpt: Humans have moved organisms around the world for centuries but it is only relatively recently that invasion ecology has grown into a mainstream research field. This book examines both the spread and impact dynamics of invasive species, placing the science of invasion biology on a new, more rigorous, theoretical footing, and proposing a concept of adaptive networks as the foundation for future research. Biological invasions are considered not as simple actions of invaders and reactions of invaded ecosystems, but as co-evolving complex adaptive systems with emergent features of network complexity and invasibility. Invasion Dynamics focuses on the ecology of invasive species and their impacts in recipient social-ecological systems. It discusses not only key advances and challenges within the traditional domain of invasion ecology, but introduces approaches, concepts, and insights from many other disciplines such as complexity science, systems science, and ecology more broadly. It will be of great value to invasion biologists analyzing spread and/or impact dynamics as well as other ecologists interested in spread processes or habitat management.

Available in PDF, EPUB and Kindle. Book excerpt: Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Researchers have been studying the ecological effects of dismantling nature for decades. In this book, Collinge evaluates this body of research, expertly synthesizing all that is known about the ecology of fragmented landscapes. Expanding on the traditional coverage of this topic, Collinge also discusses disease ecology, restoration, conservation, and planning. Not since Richard T. T. Forman's classic Land Mosaics has there been a more comprehensive examination of landscape fragmentation. Ecology of Fragmented Landscapes is critical reading for ecologists, conservation biologists, and students alike.
