Systematic conservation planning research has focused on designing systems of conservation areas that efficiently protect a comprehensive and representative set of species and habitats. Recently, there has been an emphasis on improving the adequacy of conservation area design to promote the persistence and future generation of biodiversity. Few studies have explored incorporating ecological and...

This paper develops methodology for predicting faecal coliform values in waterways when some of the data are missing, and some of the data are left-censored. Such predictions are important in predicting when bathing is safe in specific areas of Sydney harbor. The approach taken in the paper makes use of spatial information to improve these predictions.

Unmanned surface vehicles (USVs) have great value with their ability to execute hazardous and time-consuming missions over water surfaces. Recently, USVs for inland waterways attracted increasing attention potential application in autonomous monitoring, transportation, cleaning. However, unlike sailing open water, the challenges posed by scenes of waterways, such as complex distribution obstacl...

Major rivers are unique linear structures because they serve different purposes simultaneously: A habitat and dispersal route for flora fauna as well a navigation route, the site recreational economic activities source drinking water irrigation. In recent years, it has become increasingly clear that waterways must be developed in an environmentally economically sustainable socially responsible ...

Water quality is impacted significantly by urbanization. The delivery of increased nutrient loads to waterways is a primary characteristic of this land use change. Despite the recognized effects of nutrient loading on aquatic systems, the influence of urbanization on the bacterial community composition of these systems is not understood. We used massively-parallel sequencing of bacterial 16S rR...

The likely extension of commercial inland navigation in the future could increase hazards directly impacting on the nurseries of freshwater fish, especially for smaller individuals with limited swimming abilities. One limitation of the evaluation of inland navigation on fish assemblages is the lack of suitable hydraulic models. This article presents a hydraulic model to assess the increase of n...

The western pond turtle Emys (formerly Clemmys) marmorata is declining throughout its range, primarily due to loss of habitat via urbanization and conversion to agriculture. Urban waterways present several important challenges to freshwater turtle populations, but they also present an opportunity to maintain declining species in a ubiquitous habitat that has high public visibility. The arboretu...

The Umala Ogena River is one of the most famous waterways in Baubau City. During Sultanate, this river was economic lifeblood Buton people. Rivers are used for various purposes, including transportation, bathing, and washing. If ecology disturbed, all living organisms that exist will be threatened with extinction. Water pollution entry things, chemicals, energy, or other components into water, ...

 Global plastic pollution in waterways is a serious environmental concern predicted to increase the coming years with many groups currently invested monitoring and removing plastics from aquatic ecosystems. Still, available data on sources pathways of larger floating freshwater environments scarce. To bridge this gap, we present computer vision model prototype identify trash primarily nat...
