Cover Crop Mixture Diversity And Function, Angela Florence 2016 University of Nebraska-Lincoln

Cover Crop Mixture Diversity And Function, Angela Florence

Theses, Dissertations, and Student Research in Agronomy and Horticulture

The objective of this study was to evaluate the effect of cover crop mixture diversity on cover crop function. Specifically, this study evaluated the effect of cover crop species and functional richness on aboveground biomass productivity, weed suppression, soil nutrient retention, soil microbial community characteristics, and performance stability. Twenty to forty cover crop treatments were replicated three to four times at eleven sites across southeastern Nebraska using a pool of eighteen species representing three cover crop species each from six pre-defined functional groups: cool-season grasses, cool-season legumes, cool-season brassicas, warm-season grasses, warm-season legumes, and warm-season broadleaves. Each species was planted ...

The First Record Of Malformed Pectines In Genus Euscorpius (Scorpiones: Euscorpiidae), Miroslav Šarić, Jovana Tomić

Euscorpius

A teratological change in a pectinal organ of Euscorpius cf. carpathicus (C. L. Koch, 1837) from Serbia had been examined using SEM (Scanning Electron Microscopy), and compared to specimens with normally developed pectines. Possible reasons for this anomaly are discussed.


Invasive Species: A Look At Their Disastrous Effects On Ecosystems, Health, And Stability Of Native Species, Vanessa Nikolovska 2016 St. John Fisher College

Invasive Species: A Look At Their Disastrous Effects On Ecosystems, Health, And Stability Of Native Species, Vanessa Nikolovska

The Review: A Journal of Undergraduate Student Research

Invasive predators, competitors, and disease-causing pathogens are the cause of immense and often irreversible harm to the environment, presenting a serious threat to biodiversity. The problem of invasive species dates back to ancient times, when people started using different methods of transport such as horses, canoes, and camels to travel quickly, bringing with them lice, rats, microbes, cows, cats, dogs, goats, pigs, and other creatures. The actions of other species, most notably humans, play an increasing role in species invasions, as Homo sapiens have colonized almost all of the ecosystems on Earth and tend to transform natural environments into agricultural ...

Grazing Vs. Mowing: A Meta-Analysis Of Biodiversity Benefits For Grassland Management, Per Milberg 2016 Linköping University

Grazing Vs. Mowing: A Meta-Analysis Of Biodiversity Benefits For Grassland Management, Per Milberg

Per Milberg

To maintain the high biodiversity of semi-natural grasslands, management by grazing or mowing is
needed. Given the limited resources and few remaining areas, the best management method should be
used. However, only a few studies comparing the effects of mowing and grazing on grassland biodiversity
exists. Therefore, the goal of the present review was to extract as much data as possible from the
literature and evaluate them using a meta-analysis approach. We searched scientific and grey literature
for studies comparing the effects of grazing and annual mowing on outcomes relevant for biodiversity
conservation. We identified 35 relevant studies on grazing ...


Pranked By Audubon: Constantine S. Rafinesque’S Description Of John James Audubon’S Imaginary Kentucky Mammals, Neal Woodman 2016 USGS

Pranked By Audubon: Constantine S. Rafinesque’S Description Of John James Audubon’S Imaginary Kentucky Mammals, Neal Woodman

Neal Woodman

The North American naturalist Constantine S. Rafinesque spent much of the year 1818 engaged in a solo journey down the Ohio River Valley to explore parts of what was then the western United States. Along the way, he visited a number of fellow naturalists, and he spent more than a week at the Henderson, Kentucky, home of artist and ornithologist John James Audubon. During the succeeding two years, Rafinesque published descriptions of new species that resulted from his expedition, including eleven species of fishes that eventually proved to have been invented by Audubon as a prank on the credulous naturalist ...

New Clues To A Mass Extinction: Colby Geologist Robert Gastaldo And Student Researchers Unearth Evidence That Contradicts Prevailing Models About Ancient Die-Offs, Stephen Collins

Colby Magazine

Colby geologists are rewriting deep time history, altering the script of how scientists understand the mother of all mass extinctions—the End-Permian event that occurred approximately 252 million years ago. Or to suggest that they don’t, in fact, understand it.

Population Genetic Divergence Of Isle Royale Pearl Dace, Margarita Margariscus (Cyprinidae)., John F. Elder Jr., Jack R. Martin, Isaac J. Schlosser, Larry Kallemeyn 2016 Valdosta State University

Population Genetic Divergence Of Isle Royale Pearl Dace, Margarita Margariscus (Cyprinidae)., John F. Elder Jr., Jack R. Martin, Isaac J. Schlosser, Larry Kallemeyn

Georgia Journal of Science

In 1949, Hubbs and Lagler described morphological variation among pearl dace (Margariscus margarita) of inland lakes on Isle Royale, Michigan. For Harvey Lake, Hubbs and Lagler, proposed that pearl dace were sufficiently morphologically distinct to warrant subspecific status. They argued that divergence of the Harvey Lake pearl dace was due to allopatric differentiation in isolation from lower elevation lakes. Harvey Lake has been isolated by elevation from lower elevation lakes for approximately 10 to 15 thousand years. No genetic studies have been done on Isle Royale pearl dace to evaluate this hypothesis to date. Here we report the analysis of ...

New Data On The Distribution Of Butheoloides Littoralis Lourenço, Touloun Et Boumezzough, 2011 (Scorpiones: Buthidae) Oulaid, Oulaid Touloun, Moulay Abdelmonaim El Hidan, Ali Boumezzough

Euscorpius

Morocco is the region in Africa with the highest diversity of Butheoloides Hirst, 1925 species. Until now, the total number of species of this genus known from Morocco is raised to five. A field study conducted in southern Morocco discovered a new specimen of Butheloides littoralis in the Tighmi region (southeast of Tiznit), the most continental site of this species in Morocco. This specimen is the third of this endemic species of Morocco but it is the first male discovered.

Laelapine Mite (Acari: Laelapidae) Morphometric Analysis Reflects Taxonomic And Geographic Clusters Of South American Oryzomyines (Rodentia: Sigmodontinae), Donald D. Gettinger, Robert D. Owen

MANTER: Journal of Parasite Biodiversity

Ongoing efforts to survey and inventory nonvolant small mammals across the Neotropics are beginning to reveal a highly structured and diverse fauna of rodents and marsupials. By increasing the foundation of specimens in museums around the world, it has become possible, for the first time, to evaluate and quantify the similarities and differences among small mammals collected from a broad range of geographic locali­ties, ecoregions, and habitats. Because ectoparasites were sampled in the process of collecting mammalian voucher specimens, we are able to study the laelapine mites (Acari: Laelapidae) associated with well-iden­tified and verifiable host specimens. Here, we ...


Conversations With Gunanurang, Lawrence Smith 2016 WA Museum

Conversations With Gunanurang, Lawrence Smith

Landscapes: the Journal of the International Centre for Landscape and Language

Gunanurang (the Ord River) nurtured some of the original Australians productively for millennia. In less than 150 years, their relationship with the river valley and surrounding land was almost destroyed by the effects of the east Kimberley cattle industry commenced in the 1880s. The biological and archaeological surveys before and during the filling of the Lake Argyle dam were a belated attempt to understand what was being lost in the way of ecosystems and aboriginal sites. This short essay encapsulates the impact of the pastoral industry in the Ord valley.

Diversity Of Cultured Bacteria From The Perennial Ice Block Of Scarisoara Ice Cave, Romania, Corina Iţcuş, Mădălina-Denisa Pascu, Traian Brad, Aurel Perşoiu, Cristina Purcarea

International Journal of Speleology

Cave ice ecosystems represent a poorly investigated glacial environment. Diversity of cave ice bacteria and their distribution in perennial ice deposits of this underground glacial habitat could constitute a proxy for microbial response to climatic and environmental changes. Scarisoara Ice Cave (Romania) hosts one of the oldest and largest cave ice blocks worldwide. Here we report on cultured microbial diversity of recent, 400, and 900 years-old perennial ice from this cave, representing the first characterization of a chronological distribution of cave-ice bacteria. Total cell density measured by SYBR Green I epifluorescence microscopy varied in the 2.4 x 104 ...
