/ Fish and macroinvertebrate assemblage composition, instream habitat features and surrounding land use were assessed in an agriculturally developed watershed to relate overall biotic condition to patterns of land use and channel structure. Six 100-m reaches were sampled on each of three first-order warm-water tributaries of the River Raisin in southeastern Michigan. Comparisons among sites and...

In this paper we discuss the innovative software solutions offered by e-Spatial technology for the deployment of webbased and mobile spatial information management systems. This technology has been developed within the Oracle 9i Database environment and allows users to build and deploy spatially enabled Internet applications on any Oracle supported hardware platform and on any device running a ...

Electronic archives are increasingly being used to store information that needs to be available for a long time such as land register information and medical records. In order for the data in such archives to remain useful, their integrity and authenticity must be protected over their entire life span. Also, in many cases it must be possible to prove that the data existed at a certain point in ...

Emerging safety-related applications like autonomous vehicles will require high levels of navigation performance in terms accuracy while still satisfying stringent requirements integrity, availability and continuity. Achieving sub-meter land-based scenarios with GNSS-based solutions can only be achieved carrier-phase based approaches combination additional sensors. So that these considered for ...

Under the premise that land administration is one of the necessary components of sustainable development and better land management, this article reviews how progressive titling could foster new land administration procedures and associated information systems. This review is based on the objectives of progressive titling as they are developed or currently implemented in various regions in the ...

Despite being inside a protected area, Lake Sumidouro has been impacted by the anthropogenic occupation of the surrounding area since the 1970's, compromising the ecological integrity of the lake and the sustainable use of natural resources. This study examined the current trophic classification of the lake and developed methods for improving it through an integrated analysis of morphometric an...

Competing interests in land for agriculture and commodity production in tropical human-dominated landscapes make forests and biodiversity conservation particularly challenging. Establishment of protected areas in this regard is not functioning as expected due to exclusive ecological focus and poor recognition of local people’s traditional forest use and dependence. In recent years, multifunctio...

The International Arid Lands Consortium (IALC) was established in 1990 to promote research, education, and training activities related to the development, management, and reclamation of arid and semiarid lands in the Southwestern United States, the Middle East, and elsewhere in the world. The Consortium supports the ecological sustainability and environmentally sound stewardship of these lands ...

To discover mechanisms that controlled the growth of the rooting system in the earliest land plants, we identified genes that control the development of rhizoids in the liverwort Marchantia polymorpha. 336,000 T-DNA transformed lines were screened for mutants with defects in rhizoid growth, and a de novo genome assembly was generated to identify the mutant genes. We report the identification of...
