Epiphylls widely colonize vascular leaves in moist tropical forests. Understanding the effects of epiphylls on leaf traits of host plants is critical for understanding ecological function of epiphylls. A study was conducted in a rain forest to investigate leaf traits of the host plants Photinia prunifolia colonized with epiphyllous liverworts and foliicolous lichens as well as those of uncolonized leaves. Our results found that the colonization of lichens significantly decreased leaf water content (LWC), chlorophyll (Chl) a and a + b content, and Chl a/b of P. prunifolia but increased Chl b content, while that of liverworts did not affect …
Flood Extent Mapping For Namibia Using Change Detection And Thresholding With Sar, Stephanie Long, Temilola E. Fatoyinbo, Frederick Policello
Flood Extent Mapping For Namibia Using Change Detection And Thresholding With Sar, Stephanie Long, Temilola E. Fatoyinbo, Frederick Policello

A new method for flood detection change detection and thresholding (CDAT) was used with synthetic aperture radar (SAR) imagery to delineate the extent of flooding for the Chobe floodplain in the Caprivi region of Namibia. This region experiences annual seasonal flooding and has seen a recent renewal of severe flooding after a long dry period in the 1990s. Flooding in this area has caused loss of life and livelihoods for the surrounding communities and has caught the attention of disaster relief agencies. There is a need for flood extent mapping techniques that can be used to process images quickly, providing …
Pb, Sr, And Nd Isotopic Characteristics Of A Variety Of Lithologies From The Guerrero Composite Terrane, West-Central Mexico: Constraints On Their Origin, Adriana Potra, Rosemary Hickey-Vargas, Andrew W. Macfarlane, Vincent J.M. Salters

Lead, Sr, and Nd isotope analyses of Mesozoic and Cenozoic rocks from the southern part of Guerrero terrane in Mexico provide a better understanding of their origin. Metamorphic rocks collected south of Arteaga (Zihuatanejo terrane) have similar Pb isotope values to basement rocks from Nevado de Toluca, indicating a possible connection of the basement in these areas. Lead isotope ratios of rocks from the Mesozoic Guerrero and Paleozoic Mixteca terranes are similar to those of north Peruvian Mesozoic Olmos and Paleozoic Marañón complexes, but more radiogenic than Grenville-age basement of southeast Mexico (Guichicovi complex) and north Colombia (Garzón massif and …

In 2011, an annual award system was instituted to recognize outstanding Sensors papers that are related to sensing technologies and applications and meet the aims, scope and high standards of this journal [1–3]. This year, nominations were made by the Section Editor-in-Chiefs of Sensors from among all the papers published in 2010 to track citations. Reviews and full research articles were considered separately. We gladly announce that the following eight papers were awarded the Sensors Best Paper Award in 2014.
Endocranial Morphology Of The Extinct Antillean Shrew Nesophontes (Lipotyphla: Nesophontidae) From Natural And Digital Endocasts Of Cuban Taxa, Alberto Blanco-Piñón, Florentin Jean-Marie Robert Maurrasse, Francisco Javier Zavala Díaz-De La Serna, Rubén Alfonso López-Doncel, Susana Abigail Ángeles-Trigueros, Juan Hernández-Ávila, Edgar Juárez Arriaga

This paper documents and describes fossil microbial structures inferred to be of algal/bacterial origin in the Upper Cretaceous Agua Nueva Formation in the Xilitla area (San Luis Potosi, Mexico), located in the southern part of the Tampico-Misantla basin. The sequence consists of alternating decimeter-thick beds of limestone with occasional brown shale and green bentonite layers. The limeston also include intermittent beds of black chert. The sedimentary succession shows two calcareous facies: 1) dark laminated limestones containing fossil remains of holosteans, teleosteans and shark teeth, as well as lenticular layers of sedimentary pyrite, and high content of organic matter (Corg 1 …
Logging Concessions Enable Illegal Logging Crisis In The Peruvian Amazon, Matt Finer, Clinton N. Jenkins, Melissa A. Blue Sky, Justin Pine
Logging Concessions Enable Illegal Logging Crisis In The Peruvian Amazon, Matt Finer, Clinton N. Jenkins, Melissa A. Blue Sky, Justin Pine

The Peruvian Amazon is an important arena in global efforts to promote sustainable logging in the tropics. Despite recent efforts to achieve sustainability, such as provisions in the US–Peru Trade Promotion Agreement, illegal logging continues to plague the region. We present evidence that Peru's legal logging concession system is enabling the widespread illegal logging via the regulatory documents designed to ensure sustainable logging. Analyzing official government data, we found that 68.3% of all concessions supervised by authorities were suspected of major violations. Of the 609 total concessions, nearly 30% have been cancelled for violations and we expect this percentage to …
