  • ABSTRACT Gregarine Parasitism in Dragonfly Populations of Central
    ABSTRACT Gregarine Parasitism in Dragonfly Populations of Central Texas with an Assessment of Fitness Costs in Erythemis simplicicollis Jason L. Locklin, Ph.D. Mentor: Darrell S. Vodopich, Ph.D. Dragonfly parasites are widespread and frequently include gregarines (Phylum Apicomplexa) in the gut of the host. Gregarines are ubiquitous protozoan parasites that infect arthropods worldwide. More than 1,600 gregarine species have been described, but only a small percentage of invertebrates have been surveyed for these apicomplexan parasites. Some consider gregarines rather harmless, but recent studies suggest otherwise. Odonate-gregarine studies have more commonly involved damselflies, and some have considered gregarines to rarely infect dragonflies. In this study, dragonfly populations were surveyed for gregarines and an assessment of fitness costs was made in a common and widespread host species, Erythemis simplicicollis. Adult dragonfly populations were surveyed weekly at two reservoirs in close proximity to one another and at a flow-through wetland system. Gregarine prevalences and intensities were compared within host populations between genders, among locations, among wing loads, and through time. Host fitness parameters measured included wing load, egg size, clutch size, and total egg count. Of the 37 dragonfly species surveyed, 14 species (38%) hosted gregarines. Thirteen of those species were previously unreported as hosts. Gregarine prevalences ranged from 2% – 52%. Intensities ranged from 1 – 201. Parasites were aggregated among their hosts. Gregarines were found only in individuals exceeding a minimum wing load, indicating that gregarines are likely not transferred from the naiad to adult during emergence. Prevalence and intensity exhibited strong seasonality during both years at one of the reservoirs, but no seasonal trend was detected at the wetland.

Parasit- ism of adult dragonflies is widespread and frequently includes gregarine (Apicom- plexa) life stages in the gut ofthe host. This research investigates variation in gregarine parasite prevalence and load in c? versus 2 adults of Erythemis simplicicollisand Bra- 2 chymesia gravida associated with central Texas reservoirs in close proximity. Parasite prevalence was biased toward <J 6 E. simplicicollis and toward 9 2 B. gravida. Results that suggest genderbias in parasite prevalence is influenced by gender behavior and environment more so than by immuno-response differences between genders. INTRODUCTION much in Dragonflies process energy freshwaterecosystems as predatory larvae well adults. These as as predators carry a burden of gregarine intestinal parasites, but the and host relationships among parasite prevalence, load, gender are not well known. Because males and females differ in profound aspects of their biol- ogy, we must consider genders separately to understand host-parasite relation- modesof ships (i.e. transmission, prevalence, load, and effects on fitness) (ZUK & McKEAN, 1996). Morphological and/or physiological sexual dimorphismand sexual behavior differencesoften lead to differential and exposure susceptibility to parasitism (ZUK & McKEAN, 1996; SCHALK & FOR BES, 1997; EDWARDS & SMITH, 2003). Gender biases in and load parasite prevalence among vertebrates are better documented (see ZUK & McKEAN, 1996; CHRISTE et al„ 2007) than for in- vertebrates.

  • Arizona Wildlife Notebook
    ARIZONA WILDLIFE CONSERVATION ARIZONA WILDLIFE NOTEBOOK GARRY ROGERS Praise for Arizona Wildlife Notebook “Arizona Wildlife Notebook” by Garry Rogers is a comprehensive checklist of wildlife species existing in the State of Arizona. This notebook provides a brief description for each of eleven (11) groups of wildlife, conservation status of all extant species within that group in Arizona, alphabetical listing of species by common name, scientific names, and room for notes. “The Notebook is a statewide checklist, intended for use by wildlife watchers all over the state. As various individuals keep track of their personal observations of wildlife in their specific locality, the result will be a more selective checklist specific to that locale. Such information would be vitally useful to the State Wildlife Conservation Department, as well as to other local agencies and private wildlife watching groups. “This is a very well-documented snapshot of the status of wildlife species – from bugs to bats – in the State of Arizona. Much of it should be relevant to neighboring states, as well, with a bit of fine-tuning to accommodate additions and deletions to the list. “As a retired Wildlife Biologist, I have to say Rogers’ book is perhaps the simplest to understand, yet most comprehensive in terms of factual information, that I have ever had occasion to peruse. This book should become the default checklist for Arizona’s various state, federal and local conservation agencies, and the basis for developing accurate local inventories by private enthusiasts as well as public agencies. "Arizona Wildlife Notebook" provides a superb starting point for neighboring states who may wish to emulate Garry Rogers’ excellent handiwork.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

The existence of dragonflies can be used as bioindicators of good water, related to their life cycle. The difference of habitats in the Kedung Kopong and Banyak Angkrem areas affects the diversity of dragonflies found in the location. The purpose of this research was to determine the types of dragonflies and their habitats in the Kedung Kopong and Banyak Angkrem areas. The method used in this research is the point count, which is by tracing the predetermined transects and divides it into some points. The distance between the points is 15 meters while the diameter of the points is 10 meters. The result of data collection of dragonflies in the Kedung Kopong and Banyak Angkrem areas as a whole obtained 19 species which is divided into 7 families, they are Aesnidae (2 species), Libellulidae (10 species), Calopterygidae (1 species), Cholorocyphidae (1 spesies), Coenagrionidae (2 species), Euphaeidae (1 species), and Platycnemidae (1 species). Habitats in the Kedung Kopong areas is the river. Meanwhile, in Banyak Angkrem are settlements and hills. Keywords : Habitat, Inventory, Odonata, Point count.
