OCCASIONAL PAPERS OF THE MUSEUM OF ZOOLOGY UNIVERSITY OF MICHIGAN ANN ARBOR,MICHIGAN UNIVERSITYOF MICHIGANPRESS VANISHING AND EXTINCT COLONIES OF TREE SNAILS, LIGUUS PASCIATUX, IN THE VICINITY OF MIAMT, FLORIDA1 BY FRANKN. YOUNG Szib~nittedfor publicatio?~drine 15, 1950 TI-IE once numerous tropical hardwood hamrnocks in the region of Miami, Florida, are rapidly being enveloped or destroyed by the grow- ing mctropolitan and suburban area. With the destruction of these hammocks the colonies of tree snails, Liguus fasciatus, characteristic of this type of vegetational association are doomed to extinction. Many colonies are complctely lost; others are on the verge of extinc- tion and mnst surely disappear in a few more years. In view of this prospect, I believe that the followiilg notes on the location of the ham- mocBs and thcir associated colonies of Ligzcus will be of value to future workers studying the distribution, ecology, or genetics of this group of snails. Thc tree snails of the genus Liguus are colonial only because they are strictly limited to the subtropical jungle-hammocli associes and to subtropical hammock associes with the corresponding clirnax associa- tions of the Florida Keys and the souther11 mainland (see Davis, 1943). Clench and Fairchild (1939) have reviewed the taxonomy of the Florida forms, and the names used in the present paper are largely based 011 their worlr. I11 some instaiiccs I have retained names of variants placed by them ill synonymy. These names express nzore clearly the 1 Colltributioli No. 463 from the Dcpartme~itof Zoology, Indiana University.

Proceedings of the United States National Museum
PROCEEDINGS OF THE UNITED STATES NATIONAL MUSEUM by the SMITHSONIAN INSTITUTION U. S. NATIONAL MUSEUM Vol.85 Washington: 1938 No. 3039 THE CUBAN OPERCULATE LAND SHELLS OF THE SUBFAMILY CHONDROPOMINAE By Carlos de la Torre and Paul Bartsch INTRODUCTION In all tlie world there i.s no place of equivalent area that has a o-reater number of si)ecies and races of land shells than the Island of Cuba. It is a veritable paradise for the lover of mollusks, for we find not only a numerical preponderance but also beauty of outline and coloration rivaling the faunas of the Philippine and Hawaiian Islands. The interesting features presented by this fauna are not restricted in appeal to the systematic zoologists—taxonomists—for here the student of genetics and heredity also will find a veritable laboratory teeming with an endless number of problems inviting solution. In Pinar del Rio Province, in western Cuba, the Organ Mountains, because they are broken up into isolated blocks and by the even greater cutting up of the lateral folds to the north and south, now^ largely represented by the series of mogotes—hills—of varying size into which the teeth of time have cut them, show splendidly in their faunas the effects of isolation and inbreeding, resulting in an almost endless array of races, each confined to a limestone cliff, which may vary in size from a barn door to miles in extent. To such restricted habitats most of the members of the subfamily Chondropominae are more firmly wedded today than they would bo if they occupied equally distant islands, from which they might be carried by currents or waves to neighboring shores, for gi'assy inter- vals present a greater barrier to these calciphil dwellers than would the open sea. -
Florida Tree Snail Species Conservation Measures and Permitting
SPECIES CONSERVATION MEASURES AND PERMITTING GUIDELINES Effective December, 2020 Florida Tree Snail Liguus fasciatus Species Overview Status: Removed from Florida’s Endangered and Threatened Species List. Current Protections • 68A-4.001, F.A.C., General Prohibitions and Photograph by Randy Grau, FWC. Requirement – Prohibits the take, transport, sale, and possession of wildlife. • 68A-1.004, F.A.C., Take – The term take shall include taking, attempting to take, pursuing, hunting, molesting, capturing, or killing any wildlife or freshwater fish, or their nests or eggs by any means whether or not such actions result in obtaining possession of such wildlife or freshwater fish or their nests or eggs. Biological Background This section describes the biological background for this species and provides context for the following sections. It focuses on the habitats that support the Florida tree snail, and the threats faced by the species. Florida tree snails (Liguus fasciatus) have historically been found in Collier, Palm Beach, Broward, Miami-Dade, and Monroe counties (Deisler-Seno 1994). Currently the species is primarily known from Miami-Dade, Monroe, and Collier counties (Emmel and Cotter 1995; see range map). The Florida tree snail has a conical shell 40 to 70 mm (1.6 to 2.7 in) in length. The shell color is extremely variable and can be matte or glossy (Pilsbry 1946). There are 58 named color morphs of the Florida tree snail (Jones et al. 1981, Roth and Bogan 1984, Emmel and Cotter 1995; Figure 1). Research shows very low genetic variation and suggests that all color morphs belong to a single species, Liguus fasciatus (Hillis 1995). -
Dangling Shells and Dangerous Spiders: Malacophagy and Mimicry in Terrestrial Gastropods
Folia conchyliologica , n°7 , Février 2011 Dangling shells and dangerous spiders: malacophagy and mimicry in terrestrial gastropods 2 par Abraham S.H. BREURE Abstract . ─ Shells dangling on lines attached to a substratum may be either empty shell in use by spiders, or gastropods in hibernation. Previous data on dangling gastropods and malacophagy by spiders and harvestmen are summarized and discussed. Some new observations on dangling shells are reported from various localities in the West Indies. Keywords . ─ Gastropoda, Annulariidae, Cyclophoridae, Araneae, Opiliones, malacophagy, mimicry, Malaysia, West Indies. Résumé . – Les coquilles suspendues par des fils attachés à un substrat peuvent être soit des coquilles vides utilisées par les araignées, soit des gastéropodes en hivernation. Les données antérieures sur les gastéropodes suspendus et la malacophagie par les araignées et les opilions sont résumées et discutées. Quelques nouvelles observations sur les coquilles suspendues sont signalées dans diverses localités des Antilles. Mots clés . ─ Gastropoda, Annulariidae, Cyclophoridae, Araneae, Opiliones, malacophagie, mimétisme, Malaysie, Antilles. Introduction Recently DEELEMAN -REINHOLD (2009) published an observation that she, as an arachnologist, made some years ago when collecting spiders in rainforests in Borneo. She observed shells of Alycaeus (Cyclophoridae), dangling on lines attached to limestone slabs. This behaviour was cursorily reported by SCHILTHUIZEN et al . (1999). However, as Deeleman-Reinhold found eight spiderlings inside the 22 shells observed, behind the operculum, she suggested that the shells were possibly used for shelter or deposition of eggs. More generally, observations on spider-gastropod interaction are usually limited to prey-predator relationships. Although spiders have been reported in entomological literature to predate on gastropods (for a review, see NYFELLER & S YMONDSON , 2001; see also ACOSTA & M ACHADO , 2007), this is hardly reported in malacological literature (DU PREEZ , 2001; POLLARD & J ACKSON , 2004). -

Pomacea diffusa has been reported from the Ross River in Townsville in NE Queensland, and from freshwater waterbodies in the greater Brisbane area, pswich and Urangan near Maryborough in SE Queensland. Notes This genus is widely known in the aquarium trade through the so-called mystery snail, Pomacea diffusa. n countries such as the Philippines, Hawaii and parts of SE Asia, the species Pomacea canaliculata (Lamarck) is a serious pest of rice crops. -
Natural Forest Community Delineation Methods
Natural Forest Community Delineation Methods Keith A. Bradley and George D. Gann February 2, 2005 The Institute for Regional Conservation 22601 S.W. 152 Avenue; Miami, Florida 33170 George D. Gann, Executive Director Introduction The Natural Forest Community (NFC) system was established in 1984 under ordinance 89-9, Chapter 24-60 of the Miami-Dade County Code. The ordinance provides legal protection for sites designated by the county as NFCs: “Natural Forest Community shall mean all stands of trees (including their associated understory) which were designated as Natural Forest Communities on the Dade County Natural Forest Community Maps and approved by the Board of County Commissioners, pursuant to Resolution No. R-1764-84.” Factors for reviewing proposed Natural Forest Community sites in the original ordinance included: 1) Presence of endangered, threatened, rare, or endemic species (plants or animals); 2) Plant species diversity on the site; 3) Size of trees; 4) Size of site; 5) Wildlife habitat value; 6) Geological features; and 7) Percentage of site covered by non-native plant species. As required by the ordinance, quantitative evaluation criteria were developed by DERM incorporating the above factors, including separate criteria for the delineation of hardwood hammocks and pinelands. These criteria have become outdated as more scientifically rigorous criteria for delineating natural areas have been developed since 1984, primarily relating to delineation of wetland habitats. Some of the methods used to delineate NFCs by DERM proved to be ineffective including the establishment of transects to measure plant species cover and diversity on each site. As specified in section 151 of the ordinance, evaluation criteria may be revised occasionally. -
