Sistemática Y Ecología De Las Hormigas Predadoras (Formicidae: Ponerinae) De La Argentina
UNIVERSIDAD DE BUENOS AIRES Facultad de Ciencias Exactas y Naturales Sistemática y ecología de las hormigas predadoras (Formicidae: Ponerinae) de la Argentina Tesis presentada para optar al título de Doctor de la Universidad de Buenos Aires en el área CIENCIAS BIOLÓGICAS PRISCILA ELENA HANISCH Directores de tesis: Dr. Andrew Suarez y Dr. Pablo L.

En esta tesis se estudiaron de forma integral la sistemática y ecología de una subfamilia de hormigas, las ponerinas. Esta subfamilia predomina en regiones tropicales y neotropicales, estando presente en Argentina desde el norte hasta la provincia de Buenos Aires. Se utilizó un enfoque integrador, combinando análisis genéticos con morfológicos para estudiar su diversidad, en combinación con estudios ecológicos y comportamentales para estudiar la dominancia, estructura de la comunidad y posición trófica de las Ponerinas. Los resultados sugieren que la diversidad es más alta de lo que se creía, tanto por que se encontraron nuevos registros durante la colecta de nuevo material, como porque nuestros análisis sugieren la presencia de especies crípticas. Adicionalmente, demostramos que en el PN Iguazú, dos ponerinas: Dinoponera australis y Pachycondyla striata son componentes dominantes en la comunidad de hormigas. Análisis de isótopos estables revelaron que la mayoría de las Ponerinas ocupan niveles tróficos altos, con excepción de algunas especies arborícolas del género Neoponera que dependerían de néctar u otros recursos vegetales. -

Wolff1 Biology Department Trinity Christian College 6601 West College Drive Palos Heights, IL 60463 USA The following is a list of the jumping spiders that have been reported from the Caribbean region. We have interpreted this in a broad sense, so that all islands from Trinidad to the Bahamas have been included. Furthermore, we have included Bermuda, even though it is well north of the Caribbean region proper, as a more logical extension of the island fauna rather than the continental North American fauna. This was mentioned by Banks (1902b) nearly a century ago. Country or region (e. g., pantropical) records are included for those species which have broader ranges than the Caribbean area. We have not specifically included the islands of the Florida Keys, even though these could legitimately be included in the Caribbean region, because the known fauna is mostly continental. However, when Florida is known as the only continental U.S.A. -
A LIST of the JUMPING SPIDERS of MEXICO. David B. Richman and Bruce Cutler

Pagination of the original document has been retained. 63 A LIST OF THE JUMPING SPIDERS OF MEXICO. David B. Richman and Bruce Cutler The salticids of Mexico are poorly known. Only a few works, such as F. O. Pickard-Cambridge (1901), have dealt with the fauna in any depth and these are considerably out of date. Hoffman (1976) included jumping spiders in her list of the spiders of Mexico, but the list does not contain many species known to occur in Mexico and has some synonyms listed. It is our hope to present a more complete list of Mexican salticids. Without a doubt such a work is preliminary and as more species are examined using modern methods a more complete picture of this varied fauna will emerge. The total of 200 species indicates more a lack of study than a sparse fauna. We would be surprised if the salticid fauna of Chiapas, for example, was not larger than for all of the United States. Unfortunately, much of the tropical forest may disappear before this fauna is fully known. The following list follows the general format of our earlier (1978) work on the salticid fauna of the United States and Canada. We have not prepared a key to genera, at least in part because of the obvious incompleteness of the list. We hope, however, that this list will stimulate further work on the Mexican salticid fauna.

Abstract. Our latest collections in northeastern Argentina include new species of jumping spiders (Salticidae) that indicate that the diversity of this group in Argentina is indeed underestimated. This paper describes and illustrates a new species, Pachomius areteguazu sp. nov., an inhabitant of the grasslands of northeastern Argentina. Within the genus Pachomius, this new species is placed in the nigrus group (Edwards 2015) because it has a sclerotized lateral subterminal apophysis (LSA) next to the embolus, spine-shaped, possibly derived by loss of the membranous part of the LSA. Previously no females in the nigrus group were known, so we also present the first description of an epigynum for this group and discuss its relationship to the LSA with respect to copulation. Keywords. Aelurillini, Argentina, Misiones, taxonomy Introduction Pachomius Peckham & Peckham, 1896 is a genus of medium-sized jumping spiders, represented by 21 species that share a general setal patterns on the carapace to include lateral light bands and a median thoracic stripe (Edwards 2015; WSC 2021). -

Here we examine the basis of color variation in spiders and its evolutionary and ecological implications. Reversible color changes, resulting from several mechanisms, are surprisingly widespread in the group and must be distinguished from true genetic variation for color to be used as an evolutionary tool. Genetic polymorphism occurs in a large number of families and is frequently sex limited: Sex linkage has not yet been demonstrated, nor have the forces promoting sex limitation been elucidated. It is argued that the production of color is metabolically costly and is principally maintained by the action of sight-hunting predators. Key avenues for future research are suggested. INTRODUCTION Differences in color and pattern among individuals have long been recognized as providing a tractable system with which to address fundamental evolutionary questions (57). -

Spider Sex Pheromones: Emission, Reception, Structures, and Functions
Biol. Rev. (2007), 82, pp. 27–48. 27 doi:10.1111/j.1469-185X.2006.00002.x Spider sex pheromones: emission, reception, structures, and functions A. C. Gaskett* Department of Biological Sciences, Macquarie University, NSW 2109, Australia (Received 17 October 2005; revised 30 August 2006; accepted 11 September 2006) ABSTRACT Spiders and their mating systems are useful study subjects with which to investigate questions of widespread interest about sexual selection, pre- and post-copulatory mate choice, sperm competition, mating strategies, and sexual conflict. Conclusions drawn from such studies are broadly applicable to a range of taxa, but rely on accurate understanding of spider sexual interactions. Extensive behavioural experimentation demonstrates the presence of sex pheromones in many spider species, and recent major advances in the identification of spider sex pheromones merit review. Synthesised here are the emission, transmission, structures, and functions of spider sex pheromones, with emphasis on the crucial and dynamic role of sex pheromones in female and male mating strategies generally. Techniques for behavioural, chemical and electrophysiological study are summarised, and I aim to provide guidelines for incorporating sex pheromones into future studies of spider mating. In the spiders, pheromones are generally emitted by females and received by males, but this pattern is not universal. Female spiders emit cuticular and/or silk-based sex pheromones, which can be airborne or received via contact with chemoreceptors on male pedipalps. Airborne pheromones primarily attract males or elicit male searching behaviour. Contact pheromones stimulate male courtship behaviour and provide specific information about the emitter’s identity. Male spiders are generally choosy and are often most attracted to adult virgin females and juvenile females prior to their final moult. -

Many different insects appear to mimic the appearance of the salticid spiders as viewed from the front. Examples of this mimicry are reviewed with respect to the hypothesis that these are examples of predator mimicry, whereby salticid spiders are less likely to attack prey that present images of other salticid spiders.

Here we review a series of examples that may represent predator mimicry, or the mimicry of predators, in this case salticid spiders, by their prey. -

Emmel, T. C., and G. T. Austin. 1990. the Tropical Rain Forest Butterfly Fauna of Rondônia, Brazil
Vol. 1 No. 1 1990 Rondonia butterflies: EMMEL and AUSTIN 1 TROPICAL LEPIDOPTERA, 1(1): 1-12 THE TROPICAL RAIN FOREST BUTTERFLY FAUNA OF RONDONIA, BRAZIL SPECIES DIVERSITY AND CONSERVATION THOMAS C. EMMEL and GEORGE T. AUSTIN Department of Zoology, University of Florida, Gainesville, FL 32611, and Nevada State Museum and Historical Society, 700 Twin Lakes Drive, Las Vegas, NV 89107, USA ABSTRACT.— The state of Rondonia in west central Brazil apparently has the highest reported butterfly diversity in the world, with an estimated 1,500-1,600 species living within several square kilometers in the central part of that state. A preliminary checklist of over 800 identified species is given, and some of the factors contributing to this diversity are described. The tropical rain forest in this area is being rapidly cleared for development and the creation of one or more inviolate biological preserves is urgently needed in order to save a living sample of the incredibly diverse fauna and flora for study by future generations. KEY WORDS: Amazon Basin, butterfly faunas, Hesperiidae, Lycaenidae, Nymphalidae, Papilionidae, Pieridae, rain forest, Riodinidae. Rondonia, one of the newest states in western central Brazil, occupies some 93,840 square miles (243,044 sq km) in the southwestern part of the Amazon Basin of South America. This territory, which borders Bolivia to the south and west, was formerly a part of the state of Amazonas and until the last two decades, was primarily important to Brazil's economy only during the Amazon rubber boom, which collapsed in 1912. In 1943, the area was established as Guapore.
