ANNUAL REPORT 2009 Toward a Sustainable Galapagos the Events of 2009 in Galapagos Were Viewed Through an Unusual Prism
ANNUAL REPORT 2009 Toward a Sustainable Galapagos The events of 2009 in Galapagos were viewed through an unusual prism. The year celebrated the 150th anniversary of the publication of Charles Darwin’s On the Origin of Species by Natural Selection, and focused on how Galapagos has fared more than a century after Darwin’s seminal work. The international press was full of thoughtful essays on the state of biodiversity, the state of intellectual debate on evolution, and the state of the Galapagos Islands. If Darwin were to have visited Galapagos in 2009, much of what he would have seen on the uninhabited islands would have pleased him. Species that were hunted to near extinction have been brought back by careful stewardship and excellent science. The landscapes have changed very little on the uninhabited islands—the result of a strong park management system. Conservation management has evolved, yielding new and exciting developments in ecosystem restoration, invasive species control, and marine system protection. Darwin would appreciate this increasing knowledge and the wealth of new species that continue to be discovered and protected. And his naturalist’s heart would be lightened, knowing that thousands of “citizen scientists” visit these islands daily and are inspired and delighted by the natural world. Stepping back from this biological perspective, we see another, very different Galapagos. We see a social system unable to sustain basic public health and safety services. The population of Galapagos is now nearing 30,000, having doubled in less than ten years. Economic development is encouraged which is wholly inconsistent with the natural resources available. -

The primary sensory function of the modified maxillary and labial palps is reduced, and the ventral mouthparts transformed into a licking/‘sponging’ device. Many muscles have been reduced, in relation to the coleopteran groundplan or other staphylinoids. The head capsule contains voluminous glands whose appeasement secretions are crucial for the beetle survival in ant colonies. The brain, in turn, has been shifted into the neck region. -

(Coleoptera: Staphylinidae) of South Carolina, Based on Published Records
The Coleopterists Bulletin, 71(3): 513–527. 2017. ACHECKLIST OF THE ROVE BEETLES (COLEOPTERA:STAPHYLINIDAE) OF SOUTH CAROLINA,BASED ON PUBLISHED RECORDS MICHAEL S. CATERINO AND MICHAEL L. FERRO Clemson University Arthropod Collection Department of Plant and Environmental Sciences 277 Poole Agricultural Center, Clemson University Clemson, SC 29634-0310, USA [email protected], [email protected] ABSTRACT A review of the literature revealed 17 subfamilies and 355 species of rove beetles (Staphylinidae) reported from South Carolina. Updated nomenclature and references are provided for all species. The goal of this list is to set a baseline for improvement of our knowledge of the state’s staphylinid fauna, as well as to goad ourselves and others into creating new, or updating existing, regional faunal lists of the world’s most speciose beetle family.

EVOLUTION OF SECONDARY SEXUAL CHARACTERS IN PSELAPHINAE (COLEOPTERA: STAPHYLINIDAE) A D issertation Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Entomology by Laura María Vásquez Vélez August 2020 Accepted by: Dr. Michael S. Caterino, Committee Chair Dr. Peter Adler Dr. Juan Antonio Baeza Dr. Joseph Parker ABSTRACT Secondary sexual characters (SSC) are traits present only in one sex, commonly on males, and different from the reproductive organs. These characters have evolved mainly through the action of Sexual Selection, the differential mating success of organisms of the same species. Males use SSC to challenge other males for access to females, while females use these traits as signals to choose mates with overall good. SSC can manifest as horns, tusks, enlarged appendages, spines, coloration, and body size. Sexually dimorphic traits are present in all major groups of animals, including Insects. Sexual selection and secondary sexual traits have been proposed to be drivers for speciation on hypothetical bases, but empirical evidence has proven to be inconclusive. -

Among this plethora of species found with Eciton colonies, two genera of staphylinid 15 beetles, Ecitomorpha Wasmann, and Ecitophya Wasmann, have evolved to mimic the appearance and parallel the 16 colouration of the most abundant ant worker cast. Here, we study for the first time the association of these ant- 17 mimicking beetles with their ant host in an evolutionary and population genetics framework. The central emphasis 18 is on colonies of E. burchellii, the only Eciton species that harbours both genera of ant-mimicking beetles. 19 Phylogenetic and population structure analyses using the same mtDNA COI region (802bp) for ants and beetles 20 indicated that speciation patterns of the myrmecophiles were congruent with specialization to a particular Eciton 21 (sub)species. -

However, the reliability of this approach is disputed, because the resulting estimates are often inconsistent with different sets of fossils and other parameters (clock models and prior settings) in the analyses. Here, we present the λ statistic, a likelihood approach for a posteriori evaluating the reliability of estimated divergence times. The λ statistic is based on empirically derived fossilization rates and evaluates the fit of estimated divergence times to the fossil record. We tested the performance of this measure with simulated data sets.
