Note that colour values are from different sources (North America: Needham et al. 2000, Europe: Askew 1988), and hence absolute values are not directly comparable. 4 Figure A4. Scatterplots of single ordinary least-squares regressions between average colour lightness of 8,127 North American dragonfly assemblages and mean temperature of the warmest quarter. Red dots represent assemblages that were excluded from the analysis because they contained less than five species. Note that those assemblages that were excluded scatter more than those with more than five species (c.f. the coefficients of determination) due to the inherent effect of very low sampling sizes.

    David Fitch and Reinhard Jödicke for Their Unstinting Efforts to Make This Work

    EDITORIAL And so AGRION marches into its eighth year and I would like to take this opportunity of thanking all of you who have sent me accounts of your activities for inclusion in the Newsletter. But, like editors the world over, I appeal for more material. AGRION, as well as being a vehicle for passing on WDA news and information, is dedicated to the publishing of light-hearted, anecdotal, unscientific accounts of what our members have experienced. If such accounts are not published here there is a danger that all kinds of trivial, but extremely interesting and amusing, information will never see the light of day – and that would be very sad. AGRION awaits your offerings! MESSAGE FROM THE PRESIDENT - Mike May Having survived almost a year in this position, I think I'm beginning to get the hang of it. As a result, most of the work has been done by other Board members, with my role largely that of cheerleader. I do wish to make this cheer a hearty one, because working with this dedicated group has been a real source of satisfaction. Our big news, of course, is that the transition of I.J.O. from publication by Backhuys Publishers to direct publication by W.D.A. has gone very smoothly so far. Backhuys, and their principal, Wil Peters, have done a good job for us for six years and have been very cordial and professional in facilitating this transition. We believe that the change will result in cost savings and will enhance our control of production, both of which should make it possible to bring members an even better journal.

INTRODUCTION The publication of a detailed key (CARLE, 1981) to the species of Eastern North American Ophiogomphus has led to a rapid increase in our knowledge of these beautifuland somewhat secretive dragonflies. In addition to O. acuminatus CARLE (1981), the following Ophiogomphus have been recently described: O. incurvatus CARLE (1982), O. incurvatus alleghaniensis CARLE (1982), O buchardi LOUTON (1982a), O. westfalli COOK & DAIGLE (1985), and O. mainensisfastigiatus DONNELLY (1987). Ophiogomphus has also been divided into three subgenera (CARLE, 1986).Additionalrevisions within Ophiogomphus are that Ophiogomphus i. alleghaniensis is now considered a separate species (COOK & DAIGLE, 1985; CARLE 1986), and a recent study of O. buchardi has shown it to be conspecific with O. acuminatus and not with the new species considered herein described, a possibility once (LOUTON, 1982b).

  • Iowa Fish and Wildlife and Species of Greatest Conservation Need

    Chapter Three Iowa Fish and Wildlife and Species of Greatest Conservation Need Required Element #1: “Information on the distribution and abundance of species of wildlife, including low and declining populations as the state fish and wildlife agency deems appropriate, that are indicative of the diversity and health of the state’s wildlife.” Species Included in the Iowa Wildlife Action Plan The DNR is the sole agency given the responsibility to manage Iowa's fish and wildlife resources, preserve their habitats (Code of Iowa, Chapter 455A), and establish and protect state-listed endangered or threatened species (chapter 481B.4 and Iowa Administrative Code Chapter 571-77(481B)). Iowa law defines wildlife as any species of wild mammal, fish, bird, reptile or amphibian (Code of Iowa sections 456.24, 481A.1, 481A.38, 481A.39, 481A.48). In addition to taxonomic groups designated as wildlife in Iowa law, this Plan is intended to guide conservation of all Iowa’s native fauna for which an adequate level of information is available to assess the conservation status and needs. In the first version of the Plan, butterflies, land snails and fresh water mussels were included, because these invertebrates are listed on the state’s endangered and threatened species list. Dragonflies and damselflies were added when significant data were found that listed the distribution and status of species in these groups. For the 2015 version, consideration was given to adding crayfish. A total of 1,115 species were evaluated by subcommittees. Subcommittees considered all species which have been documented in Iowa, including some species which may be vagrant, expanding their range, have been introduced, or have already been extirpated (Table 3- 1).
