THE CRAYFISH (DECAPODA: CAMBARIDAE) SUBGENUS \u3ci\u3eHIATICAMBARUS\u3c/i\u3e: UNDESCRIBED DIVERSITY AND LIFE HISTORY CHARACTERISTICS OF SELECTED MEMBERS

A taxonomic study of the crayfish species Cambarus (Hiaticambarus) longirostris was conducted. Multivariate and univariate statistical analyses of morphometric data and examination of morphological characters revealed the existence of four undescribed species from populations previously considered to belong to C. longirostris; these were located on the southern extents of the range of C. longirostris. Three of these new species were morphologically similar to the group of species containing C. coosawattae, C. chasmodactylus, C. elkensis, C. longirostris, C. longulus, and C. manningi, while one was morphologically similar to the C. fasciatus, C. girardianus, and C. speciosus group. Cambarus Species A, C. Species D, and C. Species E were morphologically similar to C. longirostris and were found in tributaries of the Tennessee River in north Alabama and south Tennessee. Cambarus Species D and C. Species E were found in the Flint River drainage in Alabama and Tennessee but were not collected together. Morphologically, C. Species D differed from C. longirostris and the other putative species in possessing a carina on the acumen of the rostrum, by dactyl tuberculation, and by pigmentation pattern. Cambarus Species A and C. Species E differed from C. longirostris and from each other in aspects of chela morphometrics and in the presence or absence of qualitative characters. Individuals of C. Species A had a corneous spine on the base of the ventral surface of the rostrum, and in individuals of C. Species E the abdominal pleura were acute. Cambarus Species B was found in the upper Savannah River system in South Carolina and was morphologically similar to C. fasciatus. The known range of each of these species is restricted, and much of the suitable habitat for C. Species B was inundated by reservoir construction in the upper Savannah River drainage in the 1960s and 1970s. Three of the new species are considered Endangered using American Fisheries Society conservation categorization (C. Species B, C. Species D, and C. Species E), and C. Species A is considered Vulnerable. This study also addressed the general life history patterns of an imperiled crayfish, Cambarus (H.) elkensis. The population studied had a life span of five years, was capable of reproducing at about three years of age, and had one reproductive event per year. Females of this population of C. elkensis underwent reproductive form alternation. This is the first report of form alternation in the genus Cambarus and indicates that crayfish life histories are likely more complex than generally accepted

SunSat Design Competition 2013-2014 Second Place Winner – Team Solar Maximum LLC: Sun-Synchronous Orbits

The orbital location of PowerSats plays a critical role in determining the mass of the solar power satellite (PowerSat) transmitter and the size of the rectenna on the Earth’s surface. These in turn play an important role in the cost of deploying the PowerSat, especially the cost of launching the PowerSat into orbit as the transmitter makes up a large part of the PowerSats mass. We will consider a new approach to PowerSat orbital positioning by considering a circular sun-synchronous orbit at 5,185.3 kilometers with an inclination of 142.1 degrees. Locating the PowerSat at this location offers several benefits and only one major drawback. The benefits include small transmitter, small ground rectenna, small minimum power levels, constant energy production and constant energy delivery. The one drawback in that this location is in the inner Van Allen radiation belt, which is a high radiation environment. Locating the PowerSat in the radiation belt is problematic as the radiation can damage the solar cells. However, the use of highly concentrated solar energy can potentially be used to heal the damaged solar cells, thereby providing a reasonable solution to the problem of radiation damage. Ideally the use of highly concentrated solar energy would be used in the design of the PowerSat anyway to reduce the mass to orbit requirements. By placing the PowerSat constellation in a medium Earth orbit (MEO) that is sun-synchronous the constellation can provide continuous power to specific sites on the ground. However, SPS in this orbit, which is the most intense region of the Earth’s Van Allen radiation belt, would require dramatic advances in radiation hardening for all systems. Solar arrays, in particular have been found to be susceptible to degradation due to exposure to radiation. Self-regeneration of solar cells using heat has already been demonstrated at the experimental stage and the high heat level available at 2,000 suns solar concentration should be sufficient to heal the cells. Concentrated solar energy can potentially reduce PowerSat energy production system mass by an order of magnitude (90%). This combined with a close orbit which can reduce transmitter mass by an order of magnitude (90%), will allow for the development and deployment of much smaller, more mass efficient PowerSats. In addition to these advantages the PowerSats will also have a much lower minimum power level which means that much smaller systems can be deployed incrementally rather than building massive PowerSats as has been proposed in the past. This paper and accompanying visualization will discuss the benefits of combining concentrated solar energy at 2,000 suns concentration with an MEO sun-synchronous orbit at 5,185.3 kilometers with an inclination of 142.1 degrees to achieve a low mass PowerSat and how to overcome the problem of a high radiation environment by taking advantage of the solar energy available to periodically heal the solar cells.

Design/methodology/approach – The development of an anxiety manual and programme was part of a service development which allowed existing and established psychological therapies to be adapted for people with intellectual disability. A qualitative approach was used to better understand the views of people who experienced anxiety on a daily basis. The feedback generated was used to make modifications to the manuals and the anxiety management programme. Findings – The study has demonstrated the value of involving people with intellectual disability in the coproduction of an anxiety management programme. Additional findings identified the real-life challenges and experiences of the impact anxiety has on people’s lives. Originality/value – To our knowledge, this is the first study to involve people with intellectual disability in developing an anxiety management programme as co-production partners. This paper underlines the value of understanding and involving people as co-production partners in developing clinical interventions

Potato cyst nematodes Globodera rostochiensis and G. pallida

Innovate UK. Grant Number: 105653 (RESOLVE) Rural and Environment Science and Analytical Services Division. Grant Number: WP2.1 Scottish Funding Council. Grant Number: ODA GCRF XFC105Taxonomy: Phylum Nematoda; class Chromadorea; order Rhabditida; suborder Tylenchina; infraorder Tylenchomorpha; superfamily Tylenchoidea; family Heteroderidae; subfamily Heteroderinae; Genus Globodera. Biology: Potato cyst nematodes (PCN) are biotrophic, sedentary endoparasitic nematodes. Invasive (second) stage juveniles (J2) hatch from eggs in response to the presence of host root exudates and subsequently locate and invade the host. The nematodes induce the formation of a large, multinucleate syncytium in host roots, formed by fusion of up to 300 root cell protoplasts. The nematodes rely on this single syncytium for the nutrients required to develop through a further three moults to the adult male or female stage. This extended period of biotrophy?between 4 and 6 weeks in total?is almost unparalleled in plant?pathogen interactions. Females remain at the root while adult males revert to the vermiform body plan of the J2 and leave the root to locate and fertilize the female nematodes. The female body forms a cyst that contains the next generation of eggs. Host range: The host range of PCN is limited to plants of the Solanaceae family. While the most economically important hosts are potato (Solanum tuberosum), tomato (Solanum lycopersicum), and aubergine (Solanum melongena), over 170 species of Solanaceae are thought to be potential hosts for PCN (Sullivan et al., 2007). Disease symptoms: Symptoms are similar to those associated with nutrient deficiency, such as stunted growth, yellowing of leaves and reduced yields. This absence of specific symptoms reduces awareness of the disease among growers. Disease control: Resistance genes (where available in suitable cultivars), application of nematicides, crop rotation. Great effort is put into reducing the spread of PCN through quarantine measures and use of certified seed stocks. Useful websites: Genomic information for PCN is accessible through WormBase ParaSite.Publisher PDFPeer reviewe
