Changes in the Midgut Diverticula Epithelial Cells of the European
www.nature.com/scientificreports OPEN Changes in the midgut diverticula epithelial cells of the European cave spider, Meta menardi, under Received: 13 March 2018 Accepted: 24 August 2018 controlled winter starvation Published: xx xx xxxx Saška Lipovšek1,2,3,4, Tone Novak2, Franc Janžekovič2, Nina Brdelak5 & Gerd Leitinger 4 The European cave spider, Meta menardi, is among the most common troglophile species inhabiting the cave entrance zone in Europe, where prey is scarce in winter. Spiders feed only if prey is available; otherwise, they are subjected to long-term winter starvation. We carried out a four-month winter starvation of M. menardi under controlled conditions to analyze ultrastructural changes in the midgut diverticula epithelial cells at the beginning, in the middle and at the end of the starvation period. We used light microscopy, TEM and quantifed reserve lipids and glycogen. The midgut diverticula epithelium consisted of secretory cells, digestive cells and adipocytes. During starvation, gradual vacuolization of some digestive cells, and some necrotic digestive cells and adipocytes appeared. Autophagic structures, autophagosomes, autolysosomes and residual bodies were found in all three cell types. Spherites and the energy-reserve compounds were gradually exploited, until in some spherites only the membrane remained. Comparison between spring, autumn and winter starvation reveals that, during the growth period, M. menardi accumulate reserve compounds in spherites and protein granules, and energy-supplying lipids and glycogen, like many epigean, overwintering arthropods. In M. menardi, otherwise active all over the year, this is an adaptive response to the potential absence of prey in winter. Te European cave spider, Meta menardi (Latreille, 1804) (Araneae, Tetragnathidae) inhabit the twilight zone of most hypogean habitats across Europe. -
A Biological Inventory of Eight Caves in Northwestern Georgia with Conservation Implications
Kurt A. Buhlmann - A biological inventory of eight caves in northwestern Georgia with conservation implications. Journal of Cave and Karst Studies 63(3): 91-98. A BIOLOGICAL INVENTORY OF EIGHT CAVES IN NORTHWESTERN GEORGIA WITH CONSERVATION IMPLICATIONS KURT A. BUHLMANN1 University of Georgia, Savannah River Ecology Laboratory, Aiken, SC 29802 USA A 1995 biological inventory of 8 northwestern Georgia caves documented or re-confirmed the presence of 46 species of invertebrates, 35 considered troglobites or troglophiles. The study yielded new cave records for amphipods, isopods, diplurans, and carabid beetles. New state records for Georgia included a pselaphid beetle. Ten salamander species were in the 8 caves, including a true troglobite, the Tennessee cave salamander. Two frog, 4 bat, and 1 rodent species were also documented. One cave contained a large colony of gray bats. For carabid beetles, leiodid beetles, and millipeds, the species differed between the caves of Pigeon and Lookout Mountain. Diplurans were absent from Lookout Mountain caves, yet were present in all Pigeon Mountain caves. A comparison between 1967 and 1995 inventories of Pettijohns Cave noted the absence of 2 species of drip pool amphipods from the latter. One cave had been contaminated by a petroleum spill and the expected aquatic fauna was not found. Further inventory work is suggested and the results should be applied to management strategies that provide for both biodiver- sity protection and recreational cave use. Georgia is a cave-rich state, with most caves occurring in 29 July; Nash Waterfall Cave [NW] on 5 August; and Pigeon two distinct physiographic regions, the Cumberland Plateau Cave [PC] on 16 July (a) and 30 July (b). -

Carnivorous arachnids, such as spiders and scorpions, are notoriously known for their cannibalistic tendencies. Studies of the conflict between arachnid males and females focus mainly on spiders because of the frequent occurrence of sexual cannibalism and unique genital morphology of both sexes. The morphology, in combination with common polyandry, further promotes the sexual conflict in form of an intense sperm competition and male tactics to reduce or avoid it. Scorpion females usually mate only once per litter, but the conflict between sexes is also intense, as females can be very aggressive, and so males engage in complicated mating dances including various components considered to reduce female aggression and elicit her cooperation. -

PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK, NY 10024 Number 3579, 44 pp., 119 figures, 4 maps June 28, 2007 A Revision of the Spider Genus Zorocrates Simon (Araneae, Zorocratidae) NORMAN I. PLATNICK1, AND DARRELL UBICK2 ABSTRACT The spider genus Zorocrates is revised, and comprises at least 31 species found from the southern United States south to Central America; it provides a notable example of the loss of a functional cribellum within a relatively small (but seemingly monophyletic) group of species. Two specific names are removed from synonymy: Z. gnaphosoides O. P.-Cambridge and Z. mordax O. P.- Cambridge (from Z. fuscus Simon and Z. mistus O. P.-Cambridge, respectively). Two other specific names are newly synonymized: Z. isolatus Gertsch and Davis, with Z. unicolor (Banks), and Z. petersi Kraus, with Z. gnaphosoides O. P.-Cambridge. Males are newly described for Z. badius Simon and Z. pictus Simon; females are newly described for Z. karli Gertsch and Riechert. Twenty new species are described from Texas and Mexico.

Higgins Chuck Parker The insect Order Trichoptera, or caddisflies, consists of an estimated 50,000 species worldwide, with approximately 1700 species known from North America north of Mexico. One hundred sixty-five have been identified from Great Smoky Mountains National Park, out of possibly 300 species that may eventually be found here. This compares with a total of slightly more than 400 species presently known from Ten- nessee as a whole. Caddisflies are very abundant in the Smokies, but are rarely noticed Limnephilus sp. makes its case of plant material, by most Park visitors. Adult caddisflies are nocturnal and closely resemble moths. such as twigs and leaves. Larval caddisflies are aquatic, living in virtually all of the Parks 2000 miles of streams, as well as in the springs, seeps, ponds, and lakes. Some caddisfly larvae are free-living, ranging about the rocks and moss in the streams searching for food. Many other larvae D. Penrose D. build shelters fixed to rocks, logs, or other stable substrates. These shelters may be made almost entirely of a sheet of silk and placed over a slight depression on the substrate surface. Others build delicate tubes of silk that are kept open by the current, which also brings food to a net which they construct. The larvae then simply graze their meals from particles trapped by the nets. Larvae of the family Hydropsychidae build sturdy retreats of sand particles glued together with silk, securely fixed to rocks and logs often in the strongest currents. -

Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state. -

Recent advances Exon in Next-Generation Sequencing, specifically target capture, makes use of short fragment sizes typical of degraded Ethanol DNA, opening up the possibilities for gathering genomic data from museum specimens. This study uses museum Araneomorphae specimens and recent target capture sequencing techniques to sequence both Ultra-Conserved Elements (UCE) and exonic regions for lineages that span the modern spiders, Araneomorphae, with a focus on Palpimanoidea. While many previous studies have used target capture techniques on dried museum specimens (for example, skins, pinned insects), this study includes specimens that were collected over the last two decades and stored in 70% ethanol at room temperature. Our findings support the utility of target capture methods for examining deep relationships within Araneomorphae: sequences from both UCE and exonic loci were important for resolving relationships; a monophyletic Palpimanoidea was recovered in many analyses and there was strong support for family and generic-level palpimanoid relationships. -
