U.S. Fish & Wildlife Service Human endeavors in the conservation of imperiled species are a fairly recent development, scarcely more than a century old. In that brief span, we have witnessed the emergence of new ideas to describe the diversity of species on this planet and ways August 2005 Vol. XXX No. 1 to conserve them. In recent years, many of these ways refl ect a cooperative con- servation approach character- ized by emphasis on innovation, incentives, local involvement, and on-the-ground action. In this Bulletin, we highlight some of the programs designed to give landowners and other concerned citizens greater opportunities for innovation and involvement in wildlife conservation. These approaches are known by a variety of acronyms, but they fall under a venerable term: partnership. How can we defi ne partner- ship? Think of it as symbiosis— with awareness, creativity, and passion. U.S. Fish & Wildlife Service Montana Fish, Wildlife and Parks WASHINGTON D.C.

ENDANGERED SPECIES BULLETIN AUGUST 2005 VOLUME XXX NO. 1 3 The Crucians are Coming! by Leopoldo Miranda-Castro and Claudia Lombard The Saint Croix ground lizard (Ameiva polops) is a small lizard with adults measuring 1.5–3.5 inches (35–77 millimeters) from snout to vent. It is consid- ered one of the world’s most endangered reptiles, with fewer than 500 individuals living in three tiny islands off the coast of St. Croix in the U.S. Virgin Islands. The lizard was believed to be extinct during the early twentieth century, but it was rediscovered in 1937 on Green Cay and Protestant Cay, two of the three islands. Individuals of this endemic Crucian (meaning a resident of St. Croix) were last seen on the main island of Saint Croix in 1968.

The most heavily used habitats are beaches and upland forests. Typical vegetation of the forest are the trees Hippomane manci- nella (manchineel), Tabebuia heterophylla (pink trumpet tree), Exostema caribaeum (Caribbean princewood), and the shrubs Eupatorium sinuatum, Lantana involu- crate, and Croton betulinus. Different-sized lizards use different habitats, with smaller individuals found in more exposed habitat and larger A. polops in sites with more cover. Like most Ameivas, this species is diurnal, and it can be seen foraging for invertebrates and occasionally resting and sunning U.S. Park Service photo itself in the open. 4 ENDANGERED SPECIES BULLETIN AUGUST 2005 VOLUME XXX NO. 1 Leopoldo Miranda-Castro Green Cay National Wildlife Refuge about a dozen lizards, mostly from St. Croix ground lizard Green Cay is on the north coast of Protestant Cay.

GENERAL INFORMATION A. Methodology used to complete the review: On February 20, 2009, the U.S. Fish and Wildlife Service (Service) published a notice in the Federal Register (74 FR 7914) to announce the 5-year review of the cactus Leptocereus grantianus (no common name), and requested new information concerning the biology and status of this plant species. A 60-day public comment period was also opened. No comments were received from the public during this period. This 5-year review was prepared by the Service’s lead recovery biologist and it summarizes information that the Service has gathered in the Leptocereus grantianus file since the cactus was listed on February 26, 1993. The sources of information used for this review include the original final listing rule for the species, the recovery plan for the species, peer-reviewed literature, personal communication with qualified biologists and experts on the species, and unpublished reports from field visits and recovery activities conducted by Service biologists. We did not seek additional peer review on this 5-year review since Omar Monsegur and Carlos Pacheco, both Service biologists, and the interviewed local botanists are leading experts on this and other plants that share habitat with Leptocereus grantianus. Therefore, we believe we gathered the best available information on the species. No part of the review was contracted to an outside party.

    St. Croix Ground Lizard Ameiva polops Distribution Habitat The species’ habitat includes forested, woodland, and shrub land areas. The species is most commonly found in sandy areas and patches of direct sunlight, on the ground, or in low canopy cover and leaf litter (fallen leaves). Ground lizards spend most of their time foraging and thermoregulating. Other activities include aggressive interactions among individuals, mating, and burrowing behavior. Diet Family: Teiidae Individuals actively forage within leaf litter (fallen Order: Squamata leaves) and loosely compacted soils for a variety of invertebrates such as centipedes, moths, arthropods, hermit crabs, sand fleas, and segmented worms.

    Life: The Excitement of Biology 3(4) 254 Spatiotemporal Changes of the Herpetofaunal Community in Mount Resaca and Luis Peña Cay, Culebra National Wildlife Refuge, Culebra, Puerto Rico1 Alejandro Ríos-Franceschi2,3, Juan G. García-Cancel3, Fernando J. Bird-Picó3, and Luis D. Carrasquillo3 Abstract: Culebra, which is an archipelago that forms part of the Puerto Rican Bank, has had a limited scope of biological studies, provided the basis for this work. Culebra’s terrestrial resources were disturbed since the early 1900’s until the 1970’s. Since the 1970’s, a natural reserve, called the Culebra National Wildlife Refuge, has been managed by the United States Fish and Wildlife Service. The purpose of this research is to update the species list of reptiles and amphibians on the Island as well as to examine how spatial and temporal changes affect the diversity and abundance of its herpetofauna. Twenty species of reptiles and amphibians placed in thirteen families were identified. Two new records for Mount Resaca are Eleutherodactylus coqui Thomas, 1966 and Eleutherodactylus cochranae Grant, 1932. Meanwhile, Anolis pulchellus Duméril and Bibron, 1837 is a new record for the Luis Peña Cay. Mount Resaca has greater species richness, ten more species than the Luis Peña Cay, three species of amphibians and seven species of reptiles. The differences in herpetofaunal biodiversity (e.g. Shannon Wiener, Simpson’s Index and Margalef’s Index) between Mount Resaca and the Luis Peña Cay were statistically significant. Abiotic factors, such as temperature and humidity, and biotic factors, such as vegetation and the presence of other animal species, possibly influence the relative abundances within these communities.

Roof rats ( Rattus rattus ) occurred on two cays (Protestant Cay, Ruth Island), whereas rats were absent from the two other cays (Buck Island, Green Cay) in 2002-2003. We discovered 6 ground nests (2.1%) of three columbids out of 288 nests of five columbids, including the first documented record of ground nesting by the Scaly-naped Pigeon ( Patagioenas squamosa ). The proportion of ground nests on cays with or without rats was similar (1.5% versus 3.4%). Despite flexible nest-site placement of ground and above-ground nests of columbids on inhabited and uninhabited cays off St. Croix, the low number and restriction of ground nests to early successional habitats suggest that columbids may prefer breeding above-ground when suitable nest-sites are avail- able in more mature habitats regardless of the presence or absence of rats.
