No Ordinary Fish Tale: Working Toward A Transnational Solution To The Cod Crisis In The Gulf Of Maine, Michael Ruderman
No Ordinary Fish Tale: Working Toward A Transnational Solution To The Cod Crisis In The Gulf Of Maine, Michael Ruderman
Indiana Law Journal
In response to a National Oceanic and Atmospheric Administration (NOAA) survey that showed “record-low levels of abundance” of groundfish in the Gulf of Maine (“Gulf”), local fisherman Brian Pearce asserted: “It concerns [me] that what [NOAA is] saying and what we [the local fishermen] are seeing is such a contrast . . . . Who sees more fish in the ocean than the fishermen?” Despite Mr. Pearce’s skepticism, the state of the cod fishery in the Gulf of Maine—home to “critical” and “legendary" fishing grounds in Canadian and American territories—is, in fact, dire. According to the NOAA survey, conducted in …
Genetic Analyses Determine Connectivity Among Cave And Surface Populations Of The Jamaican Endemic Freshwater Crab Sesarma Fossarum In The Cockpit Country, Manuel Stemmer, Christoph D. Schubart
Genetic Analyses Determine Connectivity Among Cave And Surface Populations Of The Jamaican Endemic Freshwater Crab Sesarma Fossarum In The Cockpit Country, Manuel Stemmer, Christoph D. Schubart
International Journal of Speleology
The Jamaican freshwater crab Sesarma fossarum (Decapoda: Brachyura: Sesarmidae) is endemic to western central Jamaica where it occurs in cave and surface streams of karst regions. In the present study, we examine the population genetic structure of the species, providing evidence for intraspecific differentiation and genetic substructure among twelve sampled populations. Interestingly, crabs from caves appear genetically undistinguishable from representatives of nearby surface waters, despite previously observed and described morphometric differentiation. In contrast, genetic isolation takes place among populations from rivers and caves belonging to different watersheds. In one case, even populations from different tributaries of the same river were …
Gazetteer And Site-Based History Of The Ornithology Of Sabah. Malaysian Borneo, Frederick H. Sheldon
Gazetteer And Site-Based History Of The Ornithology Of Sabah. Malaysian Borneo, Frederick H. Sheldon
Occasional Papers of the Museum of Natural Science, Louisiana State University
The gazetteer lists sites in the state of Sabah, Malaysia, where birds have been collected, studied, or watched. Its purpose is to identify locations for research and birding in Sabah and to provide a brief scientific history of the more important sites. Each site description includes latitude, longitude, and general information on location. For many sites, elevation, habitat, scientific or birdwatching importance, historical notes, citations of key papers, specimen records, and records of certain species are also included.
Reproductive Timing Of Erimystax Insignis (Blotched Chub) In The Flint River Of North Alabama, Bruce Stallsmith, Josh Mann, Candice Allen
Reproductive Timing Of Erimystax Insignis (Blotched Chub) In The Flint River Of North Alabama, Bruce Stallsmith, Josh Mann, Candice Allen
Southeastern Fishes Council Proceedings
Important details of the reproductive ecology of many freshwater fishes of the species-rich southeastern United States are still poorly known. One such species is Erimystax insignis (Blotched Chub), whose range includes the Tennessee River drainage in northern Alabama, USA. To determine timing and patterns of reproductive effort, collections were made monthly of as many as 30 individuals from August 2011 through July 2012 from a 14 km stretch of the Flint River in Madison County, Alabama. Female and male gonadosomatic index (GSI) and ovarian development data indicate that reproductive activity for the species peaks from March through May. Ripe and …
Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia
Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia
International Journal of Speleology
Hypogean beetles generally live in stable environments, characterized by constant temperature and high relative humidity. Changes in the underground microclimatic conditions generally induce local migrations of the beetles through the hypogean environment in search of suitable microhabitats. We studied the seasonal dynamics and the micro-climatic preference of two Alpine endemic hypogean beetles - Sphodropsis ghilianii (Coleoptera, Carabidae) and Dellabeffaella roccae (Coleoptera, Cholevidae) - in the hypogean complex of Pugnetto (Graian Alps, Italy). We surveyed the two species for one year, using baited pitfall traps and measuring temperature and humidity along the two main caves. We used logistic regression mixed models …
