Hatching Plasticity in the Tropical Gastropod Nerita Scabricosta
Invertebrate Biology x(x): 1–10. Published 2016. This article is a U.S. Government work and is in the public domain in the USA. DOI: 10.1111/ivb.12119 Hatching plasticity in the tropical gastropod Nerita scabricosta Rachel Collin,a Karah Erin Roof, and Abby Spangler Smithsonian Tropical Research Institute, 0843-03092 Balboa, Panama Abstract. Hatching plasticity has been documented in diverse terrestrial and freshwater taxa, but in few marine invertebrates. Anecdotal observations over the last 80 years have suggested that intertidal neritid snails may produce encapsulated embryos able to signifi- cantly delay hatching. The cause for delays and the cues that trigger hatching are unknown, but temperature, salinity, and wave action have been suggested to play a role. We followed individual egg capsules of Nerita scabricosta in 16 tide pools to document the variation in natural time to hatching and to determine if large delays in hatching occur in the field. Hatching occurred after about 30 d and varied significantly among tide pools in the field. Average time to hatching in each pool was not correlated with presence of potential preda- tors, temperature, salinity, or pool size. We also compared hatching time between egg cap- sules in the field to those kept in the laboratory at a constant temperature in motionless water, and to those kept in the laboratory with sudden daily water motion and temperature changes. There was no significant difference in the hatching rate between the two laboratory treatments, but capsules took, on average, twice as long to hatch in the laboratory as in the field. -
The Marco Gonzalez Maya Site, Ambergris Caye, Belize: Assessing the Impact of Human Activities by Examining Diachronic Processes at the Local Scale
Elsevier Editorial System(tm) for Quaternary International Manuscript Draft Manuscript Number: QUATINT-D-15-00289R1 Title: The Marco Gonzalez Maya Site, Ambergris Caye, Belize: Assessing the impact of human activities by examining diachronic processes at the local scale Article Type: Socio-ecology, small-scale Keywords: Anthrosols; Maya; Belize; Soil micromorphology; Archaeobotany; Plant communities Corresponding Author: Prof. Elizabeth Graham, PhD Corresponding Author's Institution: University College London First Author: Elizabeth Graham, PhD Order of Authors: Elizabeth Graham, PhD; Richard MacPhail, Ph.D.; Simon Turner, Ph.D.; John Crowther, Ph.D.; Julia Stegemann, Ph.D.; Manuel Arroyo-Kalin, Ph.D.; Lindsay Duncan; Richard Whittet; Cristina Rosique; Phillip Austin Manuscript Region of Origin: BELIZE Abstract: Research at the Maya archaeological site of Marco Gonzalez on Ambergris Caye in Belize is socio-ecological because human activities have been a factor in the formation and fluctuation of the local marine and terrestrial environments over time. The site is one of many on Belize's coast and cayes that exhibit anomalous vegetation and dark-coloured soils. These soils, although sought for cultivation, are not typical 'Amazonian Dark Earths' but instead are distinctive to the weathering of carbonate-rich anthropogenic deposits. We tentatively term these location-specific soils as Maya Dark Earths. Our research seeks to quantify the role of human activities in long-term environmental change and to develop strategies, specifically Life Cycle Assessment (LCA), that can be applied to environmental impact modelling today. *Manuscript Click here to view linked References Graham et al., Page 1 The Marco Gonzalez Maya site, Ambergris Caye, Belize: Assessing the impact of human activities by examining diachronic processes at the local scale Elizabeth Grahama, Richard MacPhaila, Simon Turnerb, John Crowtherc, Julia Stegemannd, Manuel Arroyo-Kalina, Lindsay Duncana, Richard Whittete, Cristina Rosiquee, and Phillip Austina. -

collection, a label of the former museum is retained for all registered specimens. The names of museum in the labels are “Rijksmuseum van Geologie en Mineralogie”, “Rijksmuseum van Geologie Leiden”, or “Rijks Geologisch-Mineralogisch Museum Leiden”. Labels in Japanese letters: The limited number of specimens are accompanied by Japanese labels. In most cases, labels are directly pasted on specimens. Names are written in Katakana letters only (e.g. Fig. 1E) or both in Chinese and Katakana letters (e.g. Figs. 1B, 3C, 3F). Identification of a few specimens in Japanese label is different from current our recognition and interesting. “Ryôkotsu” in Figs. 3F and 3H means dragon bones, but they are actually fragments of molluscan shells and eroded mammalian bones, respectively. In China, fossil vertebrate bones are called “Longgu” which is written in the same Chinese characters as “Ryôkotsu” in Japan, and have been used as a crude medicine. “Mimizu-ishi” in Fig. 2E stands for an earthworm stone, and winding tubes on the rock are bore holes of boring bivalve (“Teredo” sp.) with interior lining. Other fossils were precisely identified at phylum or class level. Examples are fossil fish (“Sekigyo”: Fig. 1B), fossil of wood (“Moku-kwaseki”: Fig. 4A), stone clam (“Ishi-hamaguri”: Fig. 11A), and fossil of heart urchin (“Kaien-no-kwaseki”: Fig. 3A). Molluscan specimens in Siebold fossil collection The molluscs in the Siebold fossil collection consist of more than 40 species as described below (Figs. 5-14). This number, however, does not contain the shell fragments in sandstone (Figs. 1D-G, 2A). In the following accounts, the depository of the specimens is in the mineralogical collection in Naturalis, unless otherwise mentioned. -

Findings are compared to historical studies, 52 focusing on extensive surveys from the 1960s and 1970s. Molluscan species of public health 53 significance are identified based on their potential as vectors of algal toxins in light of the recent 54 occurrence of harmful algal blooms (HABs) in the region. Habitats sampled included intertidal 55 sand or gravel beaches, rocks and jetties, sheltered soft-sediment flats and mangroves, and shallow 56 subtidal coral reefs. -
What Maya Collapse? Terminal Classic Variation in the Maya Lowlands
J Archaeol Res (2007) 15:329–377 DOI 10.1007/s10814-007-9015-x ORIGINAL PAPER What Maya Collapse? Terminal Classic Variation in the Maya Lowlands James J. Aimers Published online: 17 August 2007 Ó Springer Science+Business Media, LLC 2007 Abstract Interest in the lowland Maya collapse is stronger than ever, and there are now hundreds of studies that focus on the era from approximately A.D. 750 to A.D. 1050. In the past, scholars have tended to generalize explanations of the collapse from individual sites and regions to the lowlands as a whole. More recent approaches stress the great diversity of changes that occurred across the lowlands during the Terminal Classic and Early Postclassic periods. Thus, there is now a consensus that Maya civilization as a whole did not collapse, although many zones did experience profound change. Keywords Maya Á Collapse Á Terminal Classic–Early Postclassic Introduction ‘‘Much has been published in recent years about the collapse of Maya civilization and its causes. It might be wise to preface this chapter with a simple statement that in my belief no such thing happened’’ (Andrews IV 1973, p. 243). More than three decades after Andrews made this statement, interest in the lowland Maya collapse is more intense than ever. Of the more than 400 books, chapters, or articles of which I am aware, over half were published in the last ten years. As always, speculation about the collapse follows contemporary trends (Wilk 1985), and widespread concern over war and the physical environment have made the lowland Maya into a cautionary tale for many (Diamond 2005; Gibson 2006; J. -

Based on literature records and original samples, we review here the knowledge of the Lebanese marine bivalve biota, tracing its changes during the last 170 yr. The updated checklist of bivalves of Lebanon yielded a total of 114 species (96 native and 18 alien taxa), accounting for ca. 26.5% of the known Mediterranean Bivalvia and thus representing a particularly poor fauna. Analysis of the 21 taxa historically described on Lebanese material only yielded 2 available names. Records of 24 species are new for the Lebanese fauna, and Lioberus ligneus is also a new record for the Mediterranean Sea. Comparisons between molluscan records by past (before 1950) and modern (after 1950) authors revealed temporal variations and qualitative modifications of the Lebanese bivalve fauna, mostly affected by the introduction of Erythraean species. The rate of recording of new alien species (evaluated in decades) revealed later first local arrivals (after 1900) than those observed for other eastern Mediterranean shores, while the peak in records in conjunc- tion with our samplings (1991 to 2010) emphasizes the need for increased field work to monitor their arrival and establishment. -

Belgium. SUMMARY: The gastropod family Hipponicidae comprises widely distributed but poorly known sedentary species. On the beach-rock of the coral reefs of Laing Island (Papua New Guinea) live rich populations of several gastropod Turbo species of which many specimens have attached to their shell a hipponicid gastropod attributed to a new species, Antisabia juliae. This new species, described in this paper, appears to have adapted its mode of life on live turbinids in several ways result- ing in morphological changes (thin basal plate loosely adherent to the supporting shell, functional eyes, very long snout, functional radula, small osphradium) and ethological changes (foraging behaviour: it appears to feed on the epiphytic com- munity growing on the host, in the vicinity of the “host” shell). Except for these characteristics, the mode of life appears quite similar to that of other hipponicid species with few big females surrounded by several much smaller males. Development occurs within the egg mass inside the female shell and a few young snails escape at the crawling stage.
