Riparian forests along streams and rivers are diverse in species, structure, and regeneration processes, and have important ecological functions in maintaining landscape and biodiversity. This book ...discusses riparian forests from subpolar to warm-temperate zones, covering headwater streams, braided rivers on alluvial fans, and low-gradient meandering rivers. It presents the dynamics and mechanisms that govern the coexistence of riparian tree species, tree demography, the response to water stress of trees, and the conservation of endangered species, and focuses on natural disturbances, life-history strategies, and the ecophysiology of trees. Because many riparian landscapes have been degraded and are disappearing at an alarming rate, the regeneration of the remaining riparian ecosystems is urgent. With contributions by more than 20 experts in diverse fields, this book offers useful information for the conservation, restoration, and rehabilitation of riparian ecosystems that remain in world streams and rivers.

Lakes change constantly in response to their surrounding landscape, and their airshed. Mirror Lake, located in the White Mountains of New Hampshire, has been carefully researched since the 1960s. ...This book, edited by Thomas C. Winter and Gene E. Likens, summarizes and interprets the extensive data collected on this lake and its watershed from 1981 to 2000, a period during which the lake was affected by a variety of climate conditions as well as significant human activity. The findings documented also identify the panoply of chemicals influenced by limnological processes and include percentages of inflow sources, percentages of water loss from seepage, surface outflow, and evaporation, and the effect of water flow on the lake nutrients.
Detection of Pathogens in Water Using Micro and Nano-Technology aims to promote the uptake of innovative micro and nano-technological approaches towards the development of an integrated, ...cost-effective nano-biological sensor useful for security and environmental assays. The book describes the concerted efforts of a large European research project and the achievements of additional leading research groups. The reported knowledge and expertise should support in the innovation and integration of often separated unitary processes. Sampling, cell lysis and DNA/RNA extraction, DNA hybridisation detection micro- and nanosensors, microfluidics, together also with computational modelling and risk assessment can be integrated in the framework of the current and evolving European regulations and needs. The development and uptake of molecular methods is revolutionizing the field of waterborne pathogens detection, commonly performed with time-consuming cultural methods. The molecular detection methods are enabling the development of integrated instruments based on biosensor that will ultimately automate the full pathway of the microbiological analysis of water.
Bu araştırma Türkiye'deki Yağmur Kuşları'nda (Charadriiformes) görülen bit türlerini belirlemek amacıyla, Eylül-Ekim 2009 tarihleri arasında, Kars'ın Kuyucuk Gölü'nde yapılmıştır. İki ailede ...(Scolopacidae ve Sternidae) yer alan beş cinse ait (Chlidonias, Gallinago, Tringa, Calidris ve Philomachus) yedi türü içeren (Chlidonias leucopterus, Gallinago gallinago, Tringa glareola, Calidris minuta, Calidris alpina, Calidris temminckii, Philomachus pugnax) 41 kuş örneği incelenmiştir. Kuşlar ağlarla yakalandıktan sonra zarar verilmeden halkalanmış ve ektoparazitler yönünden incelenerek salıverilmişlerdir. Bitleri toplamak için her kuş örneği beyaz bir kağıt üzerinde sentetik piretroidli bir insektisitle dikkatli bir şekilde ilaçlanmıştır. Daha sonra kuşlar başları dışarda kalacak şekilde 5 dak. için karton bir kutu içerisinde tutulmuşlardır. Toplanan tüm bit örnekleri %70 alkol içerisine konulmuş, %10 KOH solusyonunda saydamlaştırıldıktan ve alkol serilerinden geçirildikten sonra Kanada balsamla yapıştırılarak ve mikroskopta teşhis edilmişlerdir. İncelenen 41 kuş örneğinden 36'sının (%88) en azından bir adet bitle enfeste olduğu gözlenmiştir. Muayene edilen 9 adet Gallinago gallinago'nun 4'ünde bit saptanırken Chlidonias leucopterus, Calidris minuta, C. alpina, C. temminckii ve Philomachus pugnax örneklerinin tamamı bitlerle enfeste bulunmuştur. Kuşlarda Austromenopon sp., Austromenopon lutescens (Burmeister, 1838), A. durisetosum (Blagoveshtchensky, 1948), A. alpinum Timmermann, 1954, A. atrofulvum (Piaget, 1880), Actornithophilus totani (Schrank, 1803),
A. pustulosus (Piaget, 1880), A. stictus (Kellogg ve Chapman, 1899), A. umbrinus (Burmeister, 1838), Carduiceps scalaris (Piaget, 1880), C. zo narius (Nitzsch, 1866), C. meinertzhagani Timmermann, 1954, Quadraceps obscurus (Burmeister, 1838), Q. anagrapsus (Nitzsch, 1866), Lunaceps actophilus (Kellogg ve Chapman, 1899), Lunaceps holophaeus (Burmeister, 1838), L. drosti Timmermann, 1954, L. incoensis (Kellogg ve Chapman, 1899), Rhynonirmus scolopacis (Denny, 1842) ve Saemundssonia lobaticeps (Giebel, 1874) olmak üzere toplam 20 bit türü tespit edilmiştir. Belirtilen türlerin tamamına Türkiye'de ilk kez rastlanmış ve bu araştırmayla Türkiye'deki kuşlarda bilinen bit türü sayısı yaklaşık olarak %40 oranında artmıştır. Tringa glareola'da bulunan Austromenopon sp. muhtemelen yeni bir türdür.
This study was carried out to determine chewing lice species of waders between September-October 2009 at Lake Kuyucuk Bird Ringing Station in Kars, eastern Turkey. Fourty-one birds belonging to two families (Scolopacidae and Sternidae), five genera and the following species were examined: Chlidonias leucopterus, Gallinago gallinago, Tringa glareola, Calidris minuta, Calidris alpina, Calidris temminckii, and Philomachus pugnax. Birds were caught in mistnets, ringed, examined for ectoparasites and released unharmed. To sample chewing lice, the feathers of each bird were carefully rubbed with a synthetic pyrethroid insecticide dust, over a white piece of paper. Thereafter, birds were placed in a breathable paper bag for 5 min. All lice were collected and placed in tubes with 70% alcohol. Lice specimens were cleared in 10% KOH, mounted in Canada balsam and identified under binoculer light microscope. Thirty-six out of 41 birds examined (88%) were infested with at least one chewing louse species. All individuals of Chlidonias leucopterus, Calidris minuta, C. alpina, C. temminckii and Philomachus pugnax were infested, whereas 4 out of 9 (44.4%) Gallinago gallinago had chewing lice. A total of 20 lice species were found on birds. These were: Austromenopon sp., Austromenopon lutescens (Burmeister, 1838), A. durisetosum (Blagoveshtchensky, 1948), A. alpinum Timmermann, 1954, A. atrofulvum (Piaget, 1880), Actornithophilus totani (Schrank, 1803), A. pustulosus (Piaget, 1880), A. stictus (Kellogg and Chapman, 1899), A. umbrinus (Burmeister, 1838), Carduiceps scalaris (Piaget, 1880), C. zonarius (Nitzsch, 1866), C. meinertzhagani Timmermann, 1954, Quadraceps obscurus (Burmeister, 1838), Q. anagrapsus (Nitzsch, 1866), Lunaceps actophilus (Kellogg and Chapman, 1899), Lunaceps holophaeus (Burmeister, 1838), L. drosti Timmermann, 1954, L. incoensis (Kellogg and Chapman, 1899), Rhynonirmus scolopacis (Denny, 1842), and Saemundssonia lobaticeps (Giebel, 1874). All louse species documented here are first records for Turkey, increasing the number of bird louse species known from Turkey by about 40%. Austromenopon sp. found on Tringa glareola belongs to a species probably new to science.
This landmark scientific reference for scientists, researchers, and students of marine biology tackles the monumental task of taking a complete biodiversity inventory of the Gulf of Mexico with full ...biotic and biogeographic information. Presenting a comprehensive summary of knowledge of Gulf biota through 2004, the book includes seventy-seven chapters, which list more than fifteen thousand species in thirty-eight phyla or divisions and were written by 138 authors from seventy-one institutions in fourteen countries. This first volume of Gulf of Mexico Origin, Waters, and Biota, a multivolumed set edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle, provides information on each species' habitat, biology, and geographic range, along with full references and a narrative introduction to the group, which opens each chapter.
