Seafood is a highly traded food commodity. Farmed and captured crustaceans contribute a significant proportion with annual production exceeding 10 M metric tonnes with first sale value of $40bn. The sector is dominated by farmed tropical marine shrimp, the fastest growing sector of the global aquaculture industry. It is significant in supporting rural livelihoods and alleviating poverty in producing nations within Asia and Latin America while forming an increasing contribution to aquatic food supply in more developed countries. Nations with marine borders often also support important marine fisheries for crustaceans that are regionally traded as live animals and commodity products. …

Water-Smart Growth: Integrating Water Management And Land Use Planning, Enjie Li
Water-Smart Growth: Integrating Water Management And Land Use Planning, Enjie Li
Enjie Li
Water and urban growth are inextricably interconnected, particularly in arid regions. Urban growth and water management have generated multi-dimensional conflicts. Growing cities that seek to quench their continuously increasing thirst with limited available water resources often have adverse impacts on the environment or region from which the water is drawn. Given that land use planning is an effective tool to control and manage urban growth and it has direct influence on urban water management, a holistic land-water planning approach is needed to cope with rapid growth and water scarcity in the arid western United States. However, this land-water planning approach …

Soil Denitrification Fluxes From Three Northeastern North American Forests Across A Range Of Nitrogen Deposition, Jennifer Morse, Jorge Durán, Fred Beall, Eric Enanga, Irena Creed, Ivan Fernandez, Peter Groffman
Ivan J. Fernandez
In northern forests, large amounts of missing N that dominate N balances at scales ranging from small watersheds to large regional drainage basins may be related to N-gas production by soil microbes. We measured denitrification rates in forest soils in northeastern North America along a N deposition gradient to determine whether N-gas fluxes were a significant fate for atmospheric N inputs and whether denitrification rates were correlated with N availability, soil O2 status, or forest type. We quantified N2 and N2O fluxes in the laboratory with an intact-core method and monitored soil O2, temperature and moisture in three forests differing …

Defining Adequate Means Of Residents To Prepare Property For Protection From Wildfire, Trent Penman, Christine Eriksen, R Blanchi, M Chladil, A Gill, K Haynes, Justin Leonard, Jim Mclennan, Ross Bradstock
Defining Adequate Means Of Residents To Prepare Property For Protection From Wildfire, Trent Penman, Christine Eriksen, R Blanchi, M Chladil, A Gill, K Haynes, Justin Leonard, Jim Mclennan, Ross Bradstock
Christine Eriksen
Wildfire can result in significant loss of property and lives. Evidence shows that residents can decrease the risk of loss when they stay to defend their property. In order to safely defend a property, residents need to be adequately prepared for the wildfire conditions they face. Residents who wish to evacuate prior to the arrival of a wildfire also need to prepare their property and themselves for such an action. Despite the importance of preparation, there are no clear and quantifiable definitions of what it means to be prepared for different exposures to wildfire. Here we develop a model and …
The “Curse Of Rafinesquina:” Negative Taphonomic Feedback Exerted By Strophomenid Shells On Storm-Buried Lingulids In The Cincinnatian Series (Katian, Ordovician) Of Ohio, Rebecca Freeman, Benjamin Dattilo, Aaron Morse, Michael Blair, Steve Felton, John Pojeta
The “Curse Of Rafinesquina:” Negative Taphonomic Feedback Exerted By Strophomenid Shells On Storm-Buried Lingulids In The Cincinnatian Series (Katian, Ordovician) Of Ohio, Rebecca Freeman, Benjamin Dattilo, Aaron Morse, Michael Blair, Steve Felton, John Pojeta
Benjamin F. Dattilo
Taphonomic feedback is the idea that accumulation of organic remains either enhances the habitat for some organisms (positive taphonomic feedback), and/or degrades the habitat for others (negative taphonomic feedback). Examples of epibionts living on skeletal remains are direct evidence of positive taphonomic feedback. Disruption of infaunal burrowing activities by skeletal fragments is an example of negative taphonomic feedback; direct fossil evidence of this phenomenon has not been documented previously. Infaunal organisms are vulnerable to exhumation or entombment during storms, but organisms that burrow can also re-establish viable life positions subsequently. For example, when modern lingulids re-burrow after exhumation, they first …

Preliminary Global Assessment Of Terrestrial Biodiversity Consequences Of Sea-Level Rise Mediated By Climate Change, Shaily Menon, Jorge Soberon, Xingong Li, A. Townsend Peterson
Preliminary Global Assessment Of Terrestrial Biodiversity Consequences Of Sea-Level Rise Mediated By Climate Change, Shaily Menon, Jorge Soberon, Xingong Li, A. Townsend Peterson
Shaily Menon
Considerable attention has focused on the climatic effects of global climate change on biodiversity, but few analyses and no broad assessments have evaluated effects of sea-level rise on biodiversity. Taking advantage of new maps of marine intrusion under scenarios of 1 and 6 m sea-level rise, we calculated areal losses for all terrestrial ecoregions globally, with areal losses for particular ecoregions ranging from nil to complete. Marine intrusion is a global phenomenon, but its effects are most prominent in Southeast Asia and nearby islands, eastern North America, northeastern South America, and western Alaska. Making assumptions regarding faunal responses to reduced …
Cloning And Conservation Of Biological Diversity: Paradox, Panacea, Or Pandora's Box?, Shaily Menon, Kamaljit Bawa, Leah Gorman
Cloning And Conservation Of Biological Diversity: Paradox, Panacea, Or Pandora's Box?, Shaily Menon, Kamaljit Bawa, Leah Gorman
Shaily Menon
The success of a Scottish team in cloning a mammal from an adult tissue cell has generated considerable speculation in the popular press about potential applications to conservation biology. Possibilities that have been mentioned include cloning endangered species and creating gene banks for the germplasm of rare species. Sensational or inaccurate reports might encourage the mistaken notion that cloning technology is more advanced or reliable than it actually is. More important, such reports might foster the myth that there is no longer an urgency to conserve endangered species or their habitats as long as we have frozen germplasm and cloning …
Effectiveness Of The Protected Area Network In Biodiversity Conservation: A Case-Study Of Meghalaya State, M. Latif Khan, Shaily Menon, Kamaljit Bawa
Effectiveness Of The Protected Area Network In Biodiversity Conservation: A Case-Study Of Meghalaya State, M. Latif Khan, Shaily Menon, Kamaljit Bawa
Shaily Menon
The North-Eastern region of India is significant for biodiversity conservation because of its floristic richness and high levels of endemism. Deforestation levels are high in the region due to anthropogenic pressures. We accessed various literature sources to create a database for Meghalaya state containing information on plant species, habit, altitudinal distribution, endemism, and endangered status. Information on the existing protected area network (type, extent, and altitudinal representation) was added to the database. The database was used to assess the effectiveness of the existing protected area network in conserving the floristic biodiversity of the state. Of a total of 3331 plant …
Biodiversity Monitoring: The Missing Ingredient, Kamaljit Bawa, Shaily Menon
Biodiversity Monitoring: The Missing Ingredient, Kamaljit Bawa, Shaily Menon
Shaily Menon
With mounting losses in biological diversity, inventorying and monitoring of biodiversity to assess the magnitude and rate of losses are emerging as dominant themes in conservation biology. Inventorying has been defined as the surveying, sorting, cataloging, quantifying and mapping of entities ranging from genes to landscapes1 and monitoring has been defined as the surveillance of the compliance with or deviation from a predetermined standard2. Renner and Ricklefs3 argued that rushed inventories will compromise scientific rigor and have little influence on decision making. More recently, Stork et al.4 argued that losses in biological diversity are so severe that inventorying and monitoring …
Lion-Tailed Macaques (Macaca Silenus) In A Disturbed Forest Fragment: Activity Patterns And Time Budget, Shaily Menon, Frank Poirier
Lion-Tailed Macaques (Macaca Silenus) In A Disturbed Forest Fragment: Activity Patterns And Time Budget, Shaily Menon, Frank Poirier
Shaily Menon
We describe the activity patterns and time budget of a feral group of lion-tailed macaques that were confined to a disturbed forest fragment of 65 ha and compare the results with those obtained for groups in protected forests. The degraded nature of the study site was reflected in low tree densities, low specific diversity, gaps in the girth distribution of trees, and frequent disturbance by humans. The study group of 43 subjects was twice as large as lion-tailed macaque groups in protected habitats. They spent the most time ranging (34.0%), followed by foraging (23.7%), feeding (17.9%), resting (16.0%), and other …
