Recent Diatoms Reported From The Central United States: Register Of Taxa And Synonyms, Mark E. Eberle Nov 2017

Recent Diatoms Reported From The Central United States: Register Of Taxa And Synonyms, Mark E. Eberle

Mark E. Eberle

This list of diatoms summarizes information for more than 1000 taxa and synonyms reported in published accounts of collections made in the central United States, principally within the states of Kansas, Nebraska, and Oklahoma, but also including adjacent areas in eastern Colorado and western Missouri. The objective was to provide people working on diatom projects in this region with a base reference to help them assess the results of their research. Records from Master’s theses and references focused on fossil diatoms were not incorporated into this list. Specimens were not examined, so taxa presented here are those reported in the …


Freshwater Mussels Of Kansas: Register Of Taxa, Synonyms, And Assumed Misidentifications, Mark E. Eberle Nov 2017

Freshwater Mussels Of Kansas: Register Of Taxa, Synonyms, And Assumed Misidentifications, Mark E. Eberle

Mark E. Eberle

The literature on freshwater mussels (Mollusca: Margaritiferidae and Unionidae) of Kansas includes a collection of names of species and subspecies that makes it difficult for even experienced malacologists to decipher which taxa actually were collected. Compounding this problem is the absence of voucher specimens for some of the studies conducted in the state. This list was compiled to aid those who are conducting research and want to assess their results with reference to the earlier accounts. The alphabetical list of valid taxa, synonyms, and assumed misidentifications of freshwater mussels of Kansas is drawn from the literature and not an examination …


Catalinia, A New Scorpion Genus From Southern California, Usa And Northern Baja California, Mexico (Scorpiones: Vaejovidae), Michael E. Soleglad, Richard F. Ayrey, Matthew R. Graham, Victor Fet Nov 2017

Catalinia, A New Scorpion Genus From Southern California, Usa And Northern Baja California, Mexico (Scorpiones: Vaejovidae), Michael E. Soleglad, Richard F. Ayrey, Matthew R. Graham, Victor Fet

Victor Fet

Genus Catalinia, gen. nov. (Scorpiones: Vaejovidae) is described from southern California, USA and Baja California, Mexico. The genus is composed of four species formerly placed in Pseudouroctonus: Catalinia minima (Kraepelin, 1911), comb. nov. (type species), C. andreas (Gertsch et Soleglad, 1972), comb. nov., C. castanea (Gertsch et Soleglad, 1972), comb. nov., and C. thompsoni, comb. nov. (Gertsch et Soleglad, 1972). Major diagnostic characters of Catalinia include a carapace with a very weak anterior indentation, a very stout metasoma with little or no tapering from segment I to V, and a mating plug with two partial bases. Evidence is presented suggesting …


The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin Sep 2017

The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin

We report the remnants of five new scorpion specimens discovered dead in Levana Cave in Israel in December 2015. We confirm that they belong to the relict scorpion Akrav israchanani Levy, 2007 (Akravidae), famously described from the neighboring Ayyalon Cave, also from dead specimens. The details of morphology of the new specimens are given; they match completely the characters of A. israchanani redescribed by Fet, Soleglad & Zonstein (2011). This second record indicates a wider distribution of this unique cave scorpion, which, however, is extinct in both caves. There is still no evidence that live populations of this species exist.

The Highlands–Glades subpopulation (HGS) of Florida, USA, black bears (Ursus americanus floridanus) is small, genetically depauperate, and resides primarily within the endangered Lake Wales Ridge ecosystem, which has lost >85% of native habitat to land development. Habitat loss can reduce availability of critical natural foods and cause bears to increase reliance on anthropogenic foods (i.e., human-sourced); lands supporting the HGS are expected to lose >50% of remaining Florida black bear habitat in coming decades. We used scat analysis to describe seasonal food habits, investigate potential dietary responses to food shortages, and inform habitat conservation and human–bear conflict management. …


Hypogenic Versus Epigenic Subterranean Ecosystem: Lessons From Eastern Iberian Peninsula, Alberto Sendra, Policarp Garay, Vicente M. Ortuño, José D. Gilgado, Santiago Teruel, Ana Sofia P.S. Reboleira Jun 2017

Hypogenic Versus Epigenic Subterranean Ecosystem: Lessons From Eastern Iberian Peninsula, Alberto Sendra, Policarp Garay, Vicente M. Ortuño, José D. Gilgado, Santiago Teruel, Ana Sofia P.S. Reboleira

Ana Sofia P.S. Reboleira

Over the last 40 years, hypogenic karst/caves have become well known and hypogene speleogenesis has been used to explain the formation of some of the largest subterranean maze caves. These hypogenic systems involve confined aquifers with upwards flow, responsible for their karstification. Such spaces begun and could be remain isolated from the surface and the contiguous subterranean habitats, including the shallow ones. We studied the invertebrate fauna and the geology/speleogenesis of two recently opened caves from Eastern Iberian Peninsula, which clearly showed features of hypogenic origin. Their scarce faunistic composition, formed by non cave-adapted fauna, is similar to other hypogenic …

Genomic Plasticity And Rapid Host Switching Can Promote The Evolution Of Generalism: A Case Study In The Zoonotic Pathogen Campylobacter, Dan J. Woodcock, Peter Krusche, Norval J. C. Strachan, Ken J. Forbes, Frederick M. Cohan, Guillaume Meric, Samuel K. Sheppard Dec 2016

Genomic Plasticity And Rapid Host Switching Can Promote The Evolution Of Generalism: A Case Study In The Zoonotic Pathogen Campylobacter, Dan J. Woodcock, Peter Krusche, Norval J. C. Strachan, Ken J. Forbes, Frederick M. Cohan, Guillaume Meric, Samuel K. Sheppard

Horizontal gene transfer accelerates bacterial adaptation to novel environments, allowing selection to act on genes that have evolved in multiple genetic backgrounds. This can lead to ecological specialization. However, little is known about how zoonotic bacteria maintain the ability to colonize multiple hosts whilst competing with specialists in the same niche. Here we develop a stochastic evolutionary model and show how genetic transfer of host segregating alleles, distributed as predicted for niche specifying genes, and the opportunity for host transition could interact to promote the emergence of host generalist lineages of the zoonotic bacterium Campylobacter. Using a modelling approach …
