  • Multi-National Conservation of Alligator Lizards
    MULTI-NATIONAL CONSERVATION OF ALLIGATOR LIZARDS: APPLIED SOCIOECOLOGICAL LESSONS FROM A FLAGSHIP GROUP by ADAM G. CLAUSE (Under the Direction of John Maerz) ABSTRACT The Anthropocene is defined by unprecedented human influence on the biosphere. Integrative conservation recognizes this inextricable coupling of human and natural systems, and mobilizes multiple epistemologies to seek equitable, enduring solutions to complex socioecological issues. Although a central motivation of global conservation practice is to protect at-risk species, such organisms may be the subject of competing social perspectives that can impede robust interventions. Furthermore, imperiled species are often chronically understudied, which prevents the immediate application of data-driven quantitative modeling approaches in conservation decision making. Instead, real-world management goals are regularly prioritized on the basis of expert opinion. Here, I explore how an organismal natural history perspective, when grounded in a critique of established human judgements, can help resolve socioecological conflicts and contextualize perceived threats related to threatened species conservation and policy development. To achieve this, I leverage a multi-national system anchored by a diverse, enigmatic, and often endangered New World clade: alligator lizards. Using a threat analysis and status assessment, I show that one recent petition to list a California alligator lizard, Elgaria panamintina, under the US Endangered Species Act often contradicts the best available science.

    Learning from the extraordinary: How the highly derived larval eyes of the Sunburst Diving Beetle can give insights into aspects of holometabolous insect visual systems A dissertation submitted to the Division of Research and Advanced Studies of the University of Cincinnati In partial fulfillment of the requirements for the degree of Doctorate of Philosophy (Ph.D.) In the department of Biological Sciences of the College of Arts and Sciences 2011 by Nadine Stecher B.S., University of Rostock, 2001 M.S., University of Rostock, 2005 Committee Chair: Elke K. Buschbeck, Ph.D. Abstract Stemmata, the eyes of holometabolous insect larvae, vary greatly in number, structure and task. The stemmata of the Sunburst Diving Beetle, Thermonectus marmoratus, are among the most sophisticated. The predatory larvae have six eyes and a potentially light-sensitive spot (eye spot) adjacent to the stemmata. The forward-pointing tubular eyes Eye 1 (E1) and Eye 2 (E2) are involved in prey capture, and possess a biconvex lens, a cellular crystalline cone-like structure, and tiered retinal tissue. A distal and a proximal retina can be distinguished, which differ not only in morphology but possibly also in function. E1 has an additional retina which runs medially alongside the crystalline cone-like structure. Using transmission electron microscopic preparations, I described the ultrastructure of the retinas of the principal eyes E1 and E2. The proximal retinas are composed of photoreceptors with predominantly parallel microvilli, and neighboring rhabdomeres are oriented approximately orthogonally to each another. This rhabdomeric arrangement is typical for eyes that are polarization sensitive. A similar organization is observed in a portion of the medial retina of E1, but not in either of the distal retinas.

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).

Williams 2 1 Department of Biological Sciences, University of Toronto Scarborough, 1265 Military Trail, Toronto, ON M1C1A4, Canada 2 The Wildlife Trust, The Manor House, Broad Street, Great Cambourne, Cambridge CB23 6DH, UK; [email protected] * Correspondence: [email protected] Academic Editors: Kerry Wilkinson and Heather Bray Received: 28 April 2017; Accepted: 19 July 2017; Published: 21 July 2017 Abstract: Of the 30 extant orders of true insect, 12 are considered to be aquatic, or semiaquatic, in either some or all of their life stages. Out of these, six orders contain species engaged in entomophagy, but very few are being harvested effectively, leading to over-exploitation and local extinction. Examples of existing practices are given, ranging from the extremes of including insects (e.g., dipterans) in the dietary cores of many indigenous peoples to consumption of selected insects, by a wealthy few, as novelty food (e.g., caddisflies). The comparative nutritional worth of aquatic insects to the human diet and to domestic animal feed is examined. Questions are raised as to whether natural populations of aquatic insects can yield sufficient biomass to be of practicable and sustained use, whether some species can be brought into high-yield cultivation, and what are the requirements and limitations involved in achieving this? Keywords: aquatic insects; entomophagy; human diet; animal feed; life histories; environmental requirements 1. Introduction Entomophagy (from the Greek ‘entoma’, meaning ‘insects’ and ‘phagein’, meaning ‘to eat’) is a trait that we Homo sapiens have inherited from our early hominid ancestors.

These large, predatory, aquatic insects have the largest body size among the Heteroptera. Adults of some South American species reach 4 inches in length. Individu- als occur in ponds and ditches where they suspend below the surface, respiring through two abdominal appendages which act as siphons. During mating season they fly from Figure 2.

    Habitat Type and Permanence Determine Local Aquatic Invertebrate Community Structure in the Madrean Sky Islands Michael T. Bogan Oregon State University, Corvallis, Oregon Oscar Gutierrez-Ruacho and J. Andrés Alvarado-Castro, CESUES, Hermosillo, Sonora, Mexico David A. Lytle Oregon State University, Corvallis, Oregon Abstract—Aquatic environments in the Madrean Sky Islands (MSI) consist of a matrix of perennial and intermittent stream segments, seasonal ponds, and human-built cattle trough habitats that support a di- verse suite of aquatic macroinvertebrates. Although environmental conditions and aquatic communities are generally distinct in lotic and lentic habitats, MSI streams are characterized by isolated perennial pools for much of the year, and thus seasonally occur as lentic environments. In this study, we compared habitat characteristics and Coleoptera and Hemiptera assemblages of stream pools with those of true lentic habi- tats (seasonal ponds and cattle troughs) across the MSI. We identified 150 species across the 38 sites, and despite superficial similarities in habitat characteristics, seasonal ponds and stream pools in the MSI support distinct aquatic insect communities. Stream-exclusive species included many long-lived species with poor dispersal abilities, while pond-exclusive species tended to have rapid development times and strong dispersal abilities. We suggest that, in addition to perennial streams, seasonal aquatic habitats should also be a focus of conservation planning in the MSI. Introduction streams are found in the higher elevations (1200-2200 m) of most MSI mountain ranges.

Within Belostomatinae water bug species (Heteroptera, Belostomatidae) it has been hitherto believed that the completion of embryonic development is successful only if eggs are incubated on male hemelytra. Nevertheless, we found egg successful hatching from a back-brooding Belostoma elegans (Mayr) and B. mican- tulum (Stål) females, as well as from fertilized eggs kicked off from four back-brooder B. elegans males. One “encumbered” B. elongatum Montandon female was also recorded, but eggs did not hatch after she removed them. Rev. Biol. Trop. 54(2): 515-517. Epub 2006 Jun 01.
