Stephanie Peay (born 1959) is a British ecologist and crayfish researcher.
Peay studied at the University of Edinburgh and the University of Hull, and in 2014 was awarded a PhD [1] by the University of Leeds. She is a member of the Institute of Ecology and Environmental Management and a Chartered Environmentalist.
In her early professional career, in 1984, she compiled the first draft of the ancient woodland inventory for West Sussex. [2]
After working for the Farming and Wildlife Advisory Group she worked for Cobham Resource Consultants, later part of the Scott Wilson Group, as an ecological consultant, where her interests in the white clawed crayfish, Austropotamobius pallipes and signal crayfish, Pacifastacus leniusculus began.
As an independent crayfish researcher her research has concentrated on the protection of the UK native white clawed crayfish and restricting the invasion of the alien signal crayfish.
Peay is a leading proponent of crayfish conservation and management in Britain [3] and has produced much of the guidance on crayfish used by British ecologists and managers on survey and monitoring methods, [4] [5] restoration of habitat, [6] mitigation during works on waterbodies, [7] and, latterly, on "ark sites" to safeguard white-clawed crayfish. [8] She also provides advice and training for organisations such as the Wildlife Trusts, Environment Agency, [6] Scottish Natural Heritage, [9] BBC [10] [11] and others.
As invading signal crayfish are a major threat to native crayfish, both in Britain and in Europe, [12] Peay has studied the effects of signal crayfish on white clawed crayfish and their environment, particularly on native fish stocks, [13] and has researched control and eradication methods. [9]
She represents The Wildlife Trusts on the UK Biodiversity Action Plan Steering Group for white clawed crayfish, is a board member of the International Association of Astacology and has contributed to the European CRAYNET programme. [14]
In her employment as Associate Director, Ecology with Aecom, Peay has considerable experience of ecological surveys, ecological assessment and management in a range of habitats in the UK on many types of projects, notably in water resources development roads and airports.
She is a visiting lecturer at the University of Leeds. [15]
Crayfish are freshwater crustaceans resembling small lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as Procambarus clarkii, are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus.
The signal crayfish is a North American species of crayfish. It was introduced to Europe in the 1960s to supplement the North European Astacus astacus fisheries, which were being damaged by crayfish plague, but the imports turned out to be a carrier of that disease. The signal crayfish is now considered an invasive species across Europe, Japan, and California ousting native species there.
The Astacidae comprise the freshwater crayfish native to Europe and western North America. The family is made up of three genera: The genera Astacus and Austropotamobius are both found throughout Europe and parts of western Asia, while Pacifastacus is found on the Pacific coast of the United States and British Columbia and includes the signal crayfish and the Shasta crayfish.
Austropotamobius pallipes is an endangered European freshwater crayfish, and the only crayfish native to the British Isles. Its common names include white-clawed crayfish and Atlantic stream crayfish.
Tributyltin (TBT) is an umbrella term for a class of organotin compounds which contain the (C4H9)3Sn group, with a prominent example being tributyltin oxide. For 40 years TBT was used as a biocide in anti-fouling paint, commonly known as bottom paint, applied to the hulls of oceangoing vessels. Bottom paint improves ship performance and durability as it reduces the rate of biofouling, the growth of organisms on the ship's hull. The TBT slowly leaches out into the marine environment where it is highly toxic toward nontarget organisms. TBT is also an obesogen. After it led to collapse of local populations of organisms, TBT was banned.
The Candover Brook is a 9.6 km (6.0 mi) chalk stream in the English county of Hampshire. It is a tributary of the River Itchen, which it joins near the town of New Alresford. The stream rises from springs just to the south of the village of Preston Candover.
Strawberry Creek is the principal watercourse running through the city of Berkeley, California. Two forks rise in the Berkeley Hills of the California Coast Ranges, and form a confluence at the campus of the University of California, Berkeley. The creek then flows westward across the city to discharge into San Francisco Bay.
Greenlee Lough is a lough or lake and national nature reserve 3 miles (5 km) north of Bardon Mill, and 1.5 miles (2.4 km) north of the B6318 road in Northumberland, northern England.
The River Gowan is a short river in Cumbria, running easterly through the village of Ings before joining the River Kent at Staveley.
Threatened arthropods are defined here as any of a number of species within the phylum Arthropoda, whose extinction is likely in the foreseeable future. Estimating the number of threatened arthropod species is extremely difficult, primarily because a vast number of the species themselves are not yet named or described. Furthermore, according to Deyrup and Eisner, "The rate of destruction and degradation of natural habitats is currently so great that there are not nearly enough biologists to even catalog the arthropod species that are suddenly on the edge of extinction." In any case, independent estimates indicate that there are millions of undocumented arthropods on Earth.
Austropotamobius torrentium, also called the stone crayfish, is a European species of freshwater crayfish in the family Astacidae. It is mostly found in tributaries of the Danube, having originated in the northern part of the Balkan Peninsula.
Dowdeswell Reservoir and former water treatment works lie below the parish of Dowdeswell in Gloucestershire. They were originally built by Cheltenham Corporation to supply the town of Cheltenham with drinking water and subsequently became part of the Severn Trent network.
The River Mease is a lowland clay river in the Midlands area of England. It flows through the counties of Leicestershire, Derbyshire and Staffordshire and forms the administrative border between these counties for parts of its length.
Faxonius immunis is a species of crayfish in the family Cambaridae. It is native to North America and it is an introduced species in Europe, where it lives along the Upper Rhine. Its common names include calico crayfish and papershell crayfish.
Crayfish are eaten all over the world. Like other edible crustaceans, only a small portion of the body of a crayfish is edible. In most prepared dishes, such as soups, bisques and étouffées, only the tail portion is served. At crawfish boils or other meals where the entire body of the crayfish is presented, other portions, such as the claw meat, may be eaten.
David Lindenmayer,, is an Australian scientist and academic. His research focuses on the adoption of nature conservation practices in agricultural production areas, developing ways to improve integration of native forest harvesting and biodiversity conservation, new approaches to enhance biodiversity conservation in plantations, and improved fire management practices in Australia. He specialises in large-scale, long-term research monitoring programs in south-eastern Australia, primarily in forests, reserves, national parks, plantations, and on farm land.
Francesca Gherardi was an Italian zoologist, ethologist, and ecologist. Most of her work was performed at the Department of Biology of the University of Florence, Italy, where she was a researcher and an associate professor.
Carrickaport lough is a freshwater lake in Kiltubrid parish, south County Leitrim, northwest Ireland. Drumcong village, and Lough Scur, lie nearby. Carrickaport lough is known for quality bream and pike fishing. The ecology of Carrickaport lough, and other Leitrim waterways, is threatened by curly waterweed, zebra mussel, and freshwater clam invasive species.
Keshcarrigan lough is a mesotrophic freshwater near Keshcarrigan village, in northwest Ireland. Known for quality coarse fishing, Keshcarrigan lough allows bank fishing from concrete stands on the northern shore, two with wheelchair access. The ecology of Keshcarrigan lough, and other Leitrim waterways, is threatened by curly waterweed, zebra mussel, and freshwater clam invasive species.
Austropotamobius bihariensis is a species of crayfish in the family Astacidae. It is known to exist only in Romania being restricted to the rivers in the western Apuseni Mountains. Its proposed English common name is idle crayfish. It is supposed to have diverged/split ~15 Ma old from a common relative of A. torrentium from the Dinarides and evolved isolated due to the historically tectonic north-eastern movement of Tisza-Dacia mega-unit through the Pannonian Basin, during the Miocene. The molecular divergence in 582 base length nucleotides of COI mtDNA sequences is supported by 43 mutational steps, a differentiation of 7.4% from the sister clade of A. torrentium located in north-western Dinarides
