E. Crampton in 19201 DAVID R. HOPPER 2 AND BARRY D. SMITH 2 ABSTRACT: Tree snails of the family Partulidae have declined on Guam since World War II. One species, indigenous to the western Pacific, Partu/a radio/ata, is still locally common along stream courses in southern areas of the island. The Mariana Island endemic Samoanajragilis is present but not found in abundance anywhere on Guam. Partu/a gibba, another Mariana endemic, is currently known only from one isolated coastal valley along the northwestern coast, and appears to be in a state ofdecline. The Guam endemic Partu/a sa/ifana was not found in areas where it had been previously collected by earlier researchers, and is thus believed to be extinct. The decline and extinction ofthese snails are related to human activities. The single most important factor is likely predation by snails that were introduced as biological control agents for the giant African snail, Achatina ju/ica. The current, most serious threat is probably the introduced flatworm P/atydemus manokwari. This flatworm is also the likely cause of extinctions ofother native and introduced gastropods on Guam and may be the most important threat to the Mariana Partulidae.

The Status of the Endemic Snails of the Genus Partula (Gastropoda: Partulidae) on Pohnpei, Federated States of Micronesia
Micronesica 41(2):253–262, 2011 The status of the endemic snails of the genus Partula (Gastropoda: Partulidae) on Pohnpei, Federated States of Micronesia. Peltin Olter Pelep and Michael G. Hadfield Kewalo Marine Laboratory Pacific Biosciences Research Center; University of Hawaii at Manoa 41 Ahui Street; Honolulu, Hawaii 96813, USA Abstract—Approximately 21 terrestrial snail species are endemic to Pohnpei, Federated States of Micronesia (FSM). The only extensive sur- veys for terrestrial snails on the island were carried out by Y. Kondo in 1936. Subsequently, forests have been destroyed and non-native preda- tors have taken their toll on the gastropod fauna, and its current status is unknown. The present study focused on Partula guamensis and P. emersoni, two of approximately 120 species in the family Partulidae dis- persed across the tropical Pacific Islands. Over 40 different localities on Pohnpei were extensively searched between August 2005 and May 2006 and between May and July 2008 to assess the status of the two Partula species. The habitats searched were mixed agro-forest, disturbed forest, rain forest and cloud forest, ranging from sea level to the highest peaks and ridges on the island. No living partulid snails were found, and the only shells collected, those of Partula guamensis, were old and eroded. The absence of living partulid snails, once apparently very abundant, is a warning of the possible extinction of the entire terrestrial snail fauna of Pohnpei.

Investigating Causes of Population Decline in Captive Partula Clara And
Investigating causes of population decline in captive Partula clara and Partula tohiveana Polynesian snails Ana Gouveia, Roamin Pizzi, Paul Pearce-Kelly, Donald MacFarlane, Dave Clarke, Shaheed MacGregor, Belinda Clark and Wayne Boardman. Zoological Society of London Abstract Partula species Polynesian tree snails are small Molluscs belonging to the class Gastropoda, order Stylommatophora, family Partulidae. They are a unique genus endemic to the Pacific region and more specifically to the Society Islands. There are over one hundred species of Partula snails described with 79 species on the International Union for the Conservation of Nature (IUCN) Red List. Fifty species are currently classified as extinct, 14 as extinct in the wild and 15 as critically endangered. Wild populations have declined since the introduction of a predatory snail, Euglandina rosea, introduced to control the also introduced Giant African land snail (Achatina fulica) which had become an agricultural pest. The London Zoo co-ordinates a worldwide captive breeding programme for Partula snails and occasional high mortality rates have occurred in a variety of species. While the extinction of Partula turgida in captivity has been postulated to have been due to a Microsoridian infection investigations in to the majority of other captive Partula species population declines have failed to identify causative diseases. A study of the population dynamics of a habitat generalist and a habitat specialist Partula species and the daily minimum and maximum temperature and humidly over a three year period was performed. At the same time histopathology of dead snails was performed to help eliminate the possibility of infectious diseases playing a role in the population declines. -
Euglandina Rosea Global Invasive
FULL ACCOUNT FOR: Euglandina rosea Euglandina rosea System: Terrestrial Kingdom Phylum Class Order Family Animalia Mollusca Gastropoda Stylommatophora Spiraxidae Common name Rosige Wolfsschnecke (German), rosy wolf snail (English), cannibal snail (English) Synonym Similar species Summary The carnivorous rosy wolfsnail Euglandina rosea was introduced to Indian and Pacific Ocean Islands from the 1950s onwards as a biological control agent for the giant African snail (Achatina fulica). E. rosea is not host specific meaning that native molluscs species are at risk of expatriatioin or even extinction if this mollusc-eating snail is introduced. Partulid tree snails of the French Polynesian Islands were particularly affected; having evolved separately from each other in isolated valleys, many Partulid tree snails have been lost and today almost all the survivors exist only in zoos. view this species on IUCN Red List Species Description The shell is large (up to 76 mm in height, 27.5 mm in diameter), thick and has prominent growth lines (University of Florida 2009). The shape of the shell is fusiform with a narrow ovate-lunate aperture and a truncated columella; typically, the shell color is brownish-pink (University of Florida 2009). Adult Euglandina grow from about seven to 10 cm long (Clifford et al. 2003). Habitat Description Euglandina rosea is usually found singly in hardwood forests, roadsides and urban gardens in its native range in Florida (Hubricht 1985, University of Florida 2009). Reproduction Euglandina rosea is a cross-fertilising egg-laying hermaphrodite. Chiu and Chou (1962, in Univeristy of Florida 2009) gave details of the biology of Euglandina in Taiwan. Individuals live up to 24 months. -

Boudreau*, Boris Worm Biology Department, Dalhousie University, 1355 Oxford Street, PO Box 15000, Halifax, Nova Scotia B3H 4R2, Canada ABSTRACT: Large benthic decapods play an increasingly important role in commercial fisheries worldwide, yet their roles in the marine ecosystem are less well understood. A synthesis of exist- ing evidence for 4 infraorders of large benthic marine decapods, Brachyura (true crabs), Anomura (king crabs), Astacidea (clawed lobsters) and Achelata (clawless lobsters), is presented here to gain insight into their ecological roles and possible ecosystem effects of decapod fisheries. The reviewed species are prey items for a wide range of invertebrates and vertebrates. They are omnivorous but prefer molluscs and crustaceans as prey. Experimental studies have shown that decapods influence the structuring of benthic habitat, occasionally playing a keystone role by sup- pressing herbivores or space competitors. Indirectly, via trophic cascades, they can contribute to the maintenance of kelp forest, marsh grass, and algal turf habitats. Changes in the abundance of their predators can strongly affect decapod population trends. Commonly documented non- consumptive interactions include interference-competition for food or shelter, as well as habitat provision for other invertebrates. Anthropogenic factors such as exploitation, the creation of pro- tected areas, and species introductions influence these ecosystem roles by decreasing or increas- ing decapod densities, often with measurable effects on prey communities. -

Sachet and F.R. Fosberg (1955, 1971) are both pertinent and self-explanatory: "The great unsolved problem of modern scientific methodology is that of bibliography, that of knowing what has been accomplished already. In starting any line of investigation the scientist is faced with the choice of ignoring his predeces- sors, possibly wasting much time on work that has already been done and missing valuable information and ideas, or of spending a large proportion of his time in study of current and past literature on the field. -
Talking with Strangers: Improving Serianthes Transplant Quality with Interspecific Companions
Article Talking with Strangers: Improving Serianthes Transplant Quality with Interspecific Companions Thomas E. Marler 1,* and Ragan M. Callaway 2 1 Western Pacific Tropical Research Center, University of Guam, Mangilao, GU 96923, USA 2 Division of Biological Sciences and the Institute on Ecosystems, University of Montana, Missoula, MT 59812, USA; [email protected] * Correspondence: [email protected] Abstract: Mixtures of species in natural or agricultural systems can increase the performance of individuals or groups relative to monocultures, often through facilitative mechanisms. Mechanisms include root communication by which plants can interrogate the identity of adjacent plants and respond negatively or positively. Alternatively, mixtures of species can ameliorate the harmful effects of soil biota that are pronounced in monocultures, thereby improving plant productivity. Limited investments into roots by shade-grown Serianthes plants in nurseries have been correlated with reduced survival after transplantation to forested habitats. We used companion container cultures in two studies to determine if heterospecific neighbor, or “stranger” roots could experi- mentally increase the root growth of Serianthes grandiflora plants used as surrogates for the crit- ically endangered Serianthes nelsonii. In one study, native sympatric eudicot and pteridophyte companions increased relative root growth and conspecific companions decreased root growth in comparison to control plants that were grown with no companions. In a second study, the phylogeny of companion plants elicited different root growth responses following the order of congeneric < eudicot = monocot < gymnosperm < pteridophyte. We propose the use of stranger roots that are experimentally maintained in production containers as a passive protocol to improve relative and absolute root growth, leading to improved post-transplant growth and survival of Citation: Marler, T.E.; Callaway, R.M. -

Serianthes Nelsonii Seed Germination and Seedling Behavior Are Minimally Influenced by Chemical and Light Treatment
horticulturae Communication Serianthes nelsonii Seed Germination and Seedling Behavior are Minimally Influenced by Chemical and Light Treatment Thomas E. Marler College of Natural and Applied Sciences, University of Guam, Mangilao, Gu 96923, USA; [email protected]; Tel.: +1-671-735-2100 Received: 20 March 2019; Accepted: 12 April 2019; Published: 16 April 2019 Abstract: The role of seed imbibition and light during germination are not known for the critically endangered Serianthes nelsonii Merr. Scarified seeds were pre-soaked in gibberellic acid (GA3) up to 300 mg/L and nitrate solutions of 3000 mg/L to determine if germination was influenced by these treatments. Scarified and imbibed seeds were incubated in high red:far red and low red:far red light to determine the influence of light quality on germination traits. The GA3 and nitrate treatments did not influence germination percentage or timing, but did increase the height of newly emerged seedlings. Moreover, GA3 extended the longevity of cotyledons and shortened the window of time that seedlings required to resume height growth. These growth responses were not sustained, and all seedlings reached heights of 30 cm at a similar number of weeks. The light treatments did not influence any of the germination response traits. The results indicate that imbibing seeds with chemical solutions and providing light in a range of light quality treatments exerted a minimal influence on S. nelsonii seed germination behaviors. Imbibing seeds with water and germinating in darkness is sufficient for achieving the germination of this endangered tree species. Keywords: endangered species; Guam; imbibition; priming 1. Introduction The seed-to-seedling transition is an important phenological transition and every plant species exhibits a unique suite of requirements for germination and seedling establishment [1–3].
