--Partnerships between research scientists and land man agers can facilitate the application of research findings. Successful partnerships developed between Rocky Mountain Station scien tists and the Southwestern Region staff have been involved in addressing riparian-stream interactions. These successful partner ships involve several interpersonal and organizational consider ations. Example...
On the importance of including vegetation dynamics in Budyko’s hydrological model R. J. Donohue, M. L. Roderick, and T. R. McVicar Ecosystem Dynamics Group, Research School of Biological Sciences, Australian National University, Canberra, ACT 0200, Australia CSIRO Land and Water, Black Mountain, ACT 2601, Australia Received: 20 January 2006 – Accepted: 29 May 2006 – Published: 12 July 2006 Corr...
Remote sensing and GIS have been widely employed to study temporal and spatial urban land use changes in southern and southeastern China. However, few studies have been conducted in northeastern regions. This study analyzed land use change and spatial patterns of urban expansion in the metropolitan area of Jilin City, located on the extension of Changbai Mountain, based on aerial photos from 19...
The distribution of millipedes along an altitudinal gradient in the south of Lake Teletskoye, Altai, Russia based on new samples from the Kyga Profile sites, as well as on partly published and freshly revised material (Mikhaljova et al. 2007, 2008, 2014, Nefedieva and Nefediev 2008, Nefediev and Nefedieva 2013, Nefedieva et al. 2014), is established. The millipede diversity is estimated to be a...
Outdoor augmented reality applications are an emerging class of software systems that demand the fast identification of natural objects, such as plant species or mountain peaks, in low power mobile devices. Convolutional Neural Networks (CNN) have exhibited superior performance in a variety of computer vision tasks, but their training is a labor intensive task and their execution requires non n...
BACKGROUND AND AIMS Tribe Arabideae are the most species-rich monophyletic lineage in Brassicaceae. More than 500 species are distributed in the majority of mountain and alpine regions worldwide. This study provides the first comprehensive phylogenetic analysis for the species assemblage and tests for association of trait and characters, providing the first explanations for the enormous species...
Widespread farmland abandonment has led to significant landscape transformations of many European mountain areas. These semi-natural multi-habitat landscapes are important reservoirs of biodiversity and their abandonment has important conservation implications. In multi-habitat landscapes the adaptation of communities depends on the differential affinity of the species to the available habitats...
Kabale is a mountainous district In this paper, a review is made of land degradation within the district Land degradation is due to population pressure on the land and poor traditional land use practices. Introduction Mountain environments are very fragile and delicate ecosystems. Intensification of land use caused by an increase in population can have profound effects on the system by disturbi...
zafar as a new rapeseed cultivar is the cross which was made between 19h and sarigol line/cultivar in 2003. the pedigree selection was applied to mange the segregating generations. the results of evaluation made during 2008-09 and 2009-10 showed that zafar with an average seed yield of 3810 kg ha-1 was among superior genotypes identified. further evaluation on these genotypes as a mid-maturity/...
In this study, using the common classification systems of IGBP-17, IGBP-9, IPCC-5 and TC (vegetation, wetlands and others only), we studied spatial and areal inconsistencies in the three most recent multi-resource land cover products in a complex mountain-oasis-desert system and quantitatively discussed the uncertainties in classification system conversion. This is the first study to compare th...
