Appendix 3: Lancashire Key Species Search Results and Definition
Appendix 3: Lancashire Key Species Search Results and Definition 'Lancashire Key Species' (LKS) is used by LERN as a collective term to refer to species which have a recognised status, either nationally or locally. Specifically, it includes species identified in one or more of the following sources: The Conservation of Habitats and Species Regulations 2010 (usually referred to as the 2010 Habitats Regulations) implement Council Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora (the Habitats Directive) into national legislation. Articles 12 and 13 of the Habitats Directive contains a range of prohibitions seeking to protect species listed on Annex IV (animal and plant species in need of strict protection). European Protected Species are animals and plants that receive protection under The Conservation of Habitats and Species Regulations 2010. LKS includes species listed on Annexes II, IV and V of the Habitats Directive. These species, together with the birds protected under the Birds Directive, are called species of 'Community interest'. The Wildlife and Countryside Act 1981 (as amended) (WCA) implements parts of the Birds Directive 2009 [2] and the Berne Convention (1979) [3] into national legislation. It includes a number of Schedules which are reviewed (usually every five years) on which details of the protected species, and their level of protection, are shown. A detailed summary of the relevant sections of the Wildlife and Countryside Act, along with the protection afforded under them can be found within Paragraphs 118-122 of ODPM Circular_06/2005 . Species listed on Schedules 1, 5 and 8 are included on the list of LKS: Schedule 1 refers to Birds and their young, for which it is an offence to intentionally or recklessly disturb at, on or near an ‘active’ nest. -
Isopoda, Sphaeromatidae)
HOW CAN I MATE WITHOUT AN APPENDIX MASCULINA? THE CASE OF SPHAEROMA TEREBRANS BATE, 1866 (ISOPODA, SPHAEROMATIDAE) BY GIUSEPPE MESSANA1) CNR-Istituto per lo Studio degli Ecosistemi, Via Madonna del Piano, I-50019 Sesto Fiorentino, Firenze, Italy ABSTRACT Several hours mating behaviour of the woodborer isopod, Sphaeroma terebrans were recorded using a video camera. S. terebrans, the only species in the genus to lack an appendix masculina, has a peculiar way of mating that is completely different from that in other Isopoda. Instead of introducing the sperm into the genital opening of the female, the male releases it into the water current created by the beating of the female pleopods. The origin of this adaptation is discussed. RIASSUNTO Il comportamento sessuale dell’isopode Sphaeroma terebrans, è stato filmato per diverse ore, attraverso una telecamera. S. terebrans, l’unica specie del genere ad essere sprovvista di una appendix masculina, ha un modo di accoppiarsi del tutto particolare che è completamente differente da quello degli altri isopodi. Il maschio invece di introdurre lo sperma nella apertura genitale femminile, lo rilascia nella corrente d’acqua creata dal battito dei pleopodi. L’origine di questo adattamento viene discussa. INTRODUCTION Isopods colonize almost every environment on earth, from deep seas to desert mountains. Their long evolutionary history, the first fossil dating from the Car- boniferous (Schram, 1986), has led to great morphological variety. Despite such a wide diversity of morphotypes, the species share a common character: a copula- tory organ, constituted by a modified endopod of the male pleopod II (Brusca & Wilson, 1991). The appendix masculina (= male stylet) is used to transfer sperm to the female during mating. -
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). -
RELATIVE GROWTH ANDPOPULATION STRUCTURE OFTHE FRESHWATER CRAB, POTAMON POTAMIOS Palestinensls, in the DEAD SEA AREA
ISRAELJOURNALOF ZOOLOGY. Vol. 36.1989. pp. 133-145 RELATIVE GROWTH AND POPULATION STRUCTURE OF THE FRESHWATER CRAB, POTAMON POTAMIOS PALESTINENSlS, iJ;< IN THE DEAD SEA AREA (ISRAEL) F'RANCESCA GHERARDI AND FIORENZA MICHEU Department of Animal Biology and Genetics, University of Florence, V.Romana 17, 50125 Florence, Italy ABSlRACf Morphological and ecological studies have been carried out on three populations of the crabPotamonpotamiospalestinensis inhabiting freshwater springs in the Dead Sea area of Israel. To a certain extent, relative growth-patterns followed those already described for other Brachyura. In the males, the chelipeds showed a positive allometry with respect to carapace length. which was probably related to their function in intra- and/or inter- sexual competition. Righthandedness has been associated with the distribution of scars and mutilations over the body. The wider abdomen is a female sexual character, the allometric growth of which decreases after the puberty moult. Males were on the average bigger than females; it is advantageous for them to grow faster to the size at which they are more likely to copulate successfully. On the contrary, the optimal size of females seems to be conditioned by energetic expenditure for reproduction. INTRODUCI10N Potamonpotamios (Olivier, 1804) is a freshwater crab occurring in Anatolia, in several southern islands of the Aegean Sea, in Syria, northern Iran, Lebanon and Israel (Pretzmann, 1961, 1983a,b, 1984; Bon, 1967). In Israel, the subspecies P. potamios palestinensis (Bott, 1967) is widely represented in aquatic habitats throughout most of the country, including the arid Negev, and its distribution extends as far as the north- ernmost comer of Sinai (Flower, 1931). -

Juvenile Sphaeroma Quadridentatum Invading Female-Oœspring Groups of Sphaeroma Terebrans
Journal of Natural History, 2000, 34, 737–745 Juvenile Sphaeroma quadridentatum invading female-oŒspring groups of Sphaeroma terebrans MARTIN THIEL1 Smithsonian Marine Station, 5612 Old Dixie Highway, Fort Pierce, Fla 34946, USA (Accepted: 6 April 1999) Female isopods Sphaeroma terebrans Bate 1866 are known to host their oŒspring in family burrows in aerial roots of the red mangrove Rhizophora mangle. During a study on the reproductive biology of S. terebrans in the Indian River Lagoon, Florida, USA, juvenile S. quadridentatum were found in family burrows of S. terebrans. Between September 1997 and August 1998, each month at least one female S. terebrans was found with juvenile S. quadridentatum in its burrow. The percentage of S. terebrans family burrows that contained juvenile S. quadridenta- tum was high during fall 1997, decreased during the winter, and reached high values again in late spring/early summer 1998, corresponding with the percentage of parental female S. terebrans (i.e. hosting their own juveniles). Most juvenile S. quadridentatum were found with parental female S. terebrans, but a few were also found with reproductive females that were not hosting their own oŒspring. Non-reproductive S. terebrans (single males, subadults, non-reproductivefemales) were never found with S. quadridentatum in their burrows. The numbers of S. quadridentatum found in burrows of S. terebrans ranged between one and eight individuals per burrow. No signi® cant correlation between the number of juvenile S. quadridentatum and the numbers of juvenile S. terebrans in a family burrow existed. However, burrows with high numbers of juvenile S. quadridentatum often contained relatively few juvenile S. -
