Chelonian Perivitelline Membrane-Bound Sperm Detection: a New Breeding Management Tool
Zoo Biology 35: 95–103 (2016) RESEARCH ARTICLE Chelonian Perivitelline Membrane-Bound Sperm Detection: A New Breeding Management Tool Kaitlin Croyle,1,2 Paul Gibbons,3 Christine Light,3 Eric Goode,3 Barbara Durrant,1 and Thomas Jensen1* 1San Diego Zoo Institute for Conservation Research, Escondido, California 2Department of Biological Sciences, California State University San Marcos, San Marcos, California 3Turtle Conservancy, New York, New York Perivitelline membrane (PVM)-bound sperm detection has recently been incorporated into avian breeding programs to assess egg fertility, confirm successful copulation, and to evaluate male reproductive status and pair compatibility. Due to the similarities between avian and chelonian egg structure and development, and because fertility determination in chelonian eggs lacking embryonic growth is equally challenging, PVM-bound sperm detection may also be a promising tool for the reproductive management of turtles and tortoises. This study is the first to successfully demonstrate the use of PVM-bound sperm detection in chelonian eggs. Recovered membranes were stained with Hoechst 33342 and examined for sperm presence using fluorescence microscopy. Sperm were positively identified for up to 206 days post-oviposition, following storage, diapause, and/or incubation, in 52 opportunistically collected eggs representing 12 species. However, advanced microbial infection frequently hindered the ability to detect membrane-bound sperm. Fertile Centrochelys sulcata, Manouria emys,andStigmochelys pardalis eggs were used to evaluate the impact of incubation and storage on the ability to detect sperm. Storage at À20°C or in formalin were found to be the best methods for egg preservation prior to sperm detection. Additionally, sperm-derived mtDNA was isolated and PCR amplified from Astrochelys radiata, C. -

Eastern Spiny Softshell
Eastern Spiny Softshell The Eastern Spiny Softshell Turtle, an introduced species, is unlike any other species of turtle in New Jersey, with its leathery, flattened shell, and its long narrow snout. Eastern Spiny Softshell Introduced Species - Pl.7 (Apalone spinifera spinifera) Identification: Adult females 6 1/2" - 18", males 5" - 9 1/4". The Eastern Spiny Softshell is almost perfectly round with a very flattened, leathery carapace that lacks scutes. Also note the characteristic long, narrow, tubular snout. Three characteristics that distinguish this from other softshells (which are not found in New Jersey) are streaked and spotted feet, a horizontal ridge in each nostril, and small spiny projections on the carapace. The carapace is light tan, like wet sand; a thin dark line encircles the carapace near the rim. The carapace of the male is marked with dark, round spots, while the female may be somewhat darker and more mottled. Where to find them: The Eastern Spiny Softshell is typically limited to rivers; however, it can also be found in lakes where mud bars are available. It is sometimes seen floating at the surface, where the shape is easily identifiable. Be careful if handling this species: it can claw and bite fiercely. When to find them: Active May through September. Range: An introduced and well-established population in the Maurice River system, Cumberland County and in the Raritan River Watershed. Eastern Spiny Softshell (Apalone spinifera spinifera) - text pg. 16 Key Features - Long, narrow, and tubular snout. - Carapace: flattened, leathery, and lacking scutes. - Light tan or brown in color.

The species inhabits the rivers and reservoirs of southern peninsular India, replacing the more familiar Indian Softshell Turtle, N. gangetica, of northern India. The turtle is apparently rare within its range, even within protected areas, which is suspected to be due to a past history of exploitation. -
ECUADOR – Galapagos Giant Tortoises Stolen From
CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA NOTIFICATION TO THE PARTIES No. 2018/076 Geneva, 30 October 2018 CONCERNING: ECUADOR Galapagos giant tortoises stolen from breeding center 1. This Notification is being published at the request of Ecuador. 2. The CITES Management Authority of Ecuador informed the Secretariat that on 27 September 2018, the Galapagos National Park Directorate filed a criminal complaint in Ecuador following the theft of 123 live Galapagos giant tortoises (Chelonoidis niger) from the Galapagos National Park breeding center on Isabela Island. 3. The Galapagos giant tortoise (Chelonoidis niger1) is included in CITES Appendix I. 4. The stolen tortoises range from one to six years in age. One-year-old Galapagos giant tortoises may be around six centimetres in carapace length and weigh an estimated 200 grams. A six-year-old Galapagos giant tortoise could range from 12 to 30 centimetres in carapace length, and weigh around two kilograms. 5. The likely market for the stolen specimens is outside of Ecuador, and the CITES Management Authority of Ecuador therefore requests that the present Notification be distributed as widely as possible among police, customs and wildlife enforcement authorities. 6. Parties are requested to inform the CITES Management Authority of Ecuador should any permits or certificates regarding trade in these specimens be received. The Management Authority of Ecuador also requests that CITES Management Authorities do not approve any export, import or re-export permit applications related to this species before consulting with the CITES Management Authority of Ecuador. 7. Parties that seize illegally traded specimens of Chelonoidis niger are also requested to communicate information about these seizures to the Management Authority of Ecuador. -
Spiny Softshell Turtle: What You Can Do to Help the Spiny Softshell Turtle (Apalone Spinifera) Is a Medium to Large-Sized Freshwater Turtle
Saving Spiny Softshell Turtle: What you can do to help The Spiny Softshell Turtle (Apalone spinifera) is a medium to large-sized freshwater turtle. Females can grow more than 4 times as big as males. Their carapace (top shell) is olive to tan, flat, round, keelless (no raised ridge down the centre of the shell), and leathery. The surface of the carapace may be slightly rough, like sandpaper, especially in adult males. Adult males have black circles on their carapace but females have a mottled or blotched pattern. The head and legs are green to gray, with a pattern of dark spots and yellowish-green stripes. The tubular snout has large nostrils, the lips are yellowish with dark spots, and the jaws are sharp. All four feet are webbed, and the webbing Photo: Scott Gillingwater extends up the back legs. Do you live near Spiny Softshell Field check Turtles? Long neck In the Carolinian zone the Spiny Softshell Turtle Long snout can be found in Lake St. Clair, Lake Erie Very flat, leathery, olive to brownish (including major tributaries like the Thames and coloured carapace Sydenham Rivers), and western Lake Ontario. They live in soft-bottomed rivers and lakes. They Very fast on land and in water are often seen at or just downstream of river Buries into the mud and then wiggles bends. They spend a lot of time basking on to settle the mud over the shell sunlit riverbanks, logs, rocks, and some artificial structures. They hunt for food in riffles, creeks, shallow inlets, and areas with vegetative debris and aquatic plants.
