Aquatic Conservation: Marine and Freshwater Ecosystems > 34 > 1 > n/a - n/a

The use of traditional in situ methods for underwater surveys to map freshwater mussel habitats is limited by challenges such as water transparency, depth and high labour demands. In this study, adaptive resolution imaging sonar (ARIS) was applied to monitor mussel distribution and abundance. In contrast to conventional quadrat surveys, this acoustic survey is non‐invasive and enables direct observation...

Journal of Ecological Engineering > 2023 > Vol. 24, nr 2 > 31--38

Toxic pollutants of industrial origin can be dangerous for professionals who come into contact with them at work, and also for the people who live near the sources of environmental hazards. There is a known relationship between the soil pollution with heavy metals and the morbidity of the population. This paper reports a study of the soil pollution with ions of heavy metals in the Turkestan region,...

Concurrency and Computation: Practice and Experience > 34 > 11 > n/a - n/a

Understanding the statistical relations among the remote sensing data and observed water quality parameters is the necessary task to develop an estimator model. In order to estimate the exact water quality parameter distribution map of the study area from remote sensing data, this present study proposed an empirical mathematical relational and signature (EMRS) model. Through this EMRS model, an environmental...

Spatiotemporal modelling of abundance from multiple data sources in an integrated spatial distribution model

Nicolas Strebel, Marc Kéry, Jérôme Guélat, Thomas Sattler

Journal of Biogeography > 49 > 3 > 563 - 575

Aim In biodiversity monitoring, observational data are often collected in multiple, disparate schemes with greatly varying degrees of standardization and possibly at different spatial and temporal scales. Technical advances also change the type of data over time. The resulting heterogeneous datasets are often deemed to be incompatible. Consequently, many available datasets may be ignored in practical...

EUNIS Habitat Classification: Expert system, characteristic species combinations and distribution maps of European habitats

Milan Chytrý, Lubomír Tichý, Stephan M. Hennekens, Ilona Knollová, more

Applied Vegetation Science > 23 > 4 > 648 - 675

Aim The EUNIS Habitat Classification is a widely used reference framework for European habitat types (habitats), but it lacks formal definitions of individual habitats that would enable their unequivocal identification. Our goal was to develop a tool for assigning vegetation‐plot records to the habitats of the EUNIS system, use it to classify a European vegetation‐plot database, and compile statistically‐derived...

Distribution, status, and recent population dynamics of Alpine ibex Capra ibex in Europe

Alice Brambilla, Achaz Von Hardenberg, Luca Nelli, Bruno Bassano

Mammal Review > 50 > 3 > 267 - 277

Despite its recent successful and well‐documented reintroduction history, a comprehensive and current update of the distribution and status of the Alpine ibex Capra ibex is lacking. As some concerns persist about its conservation, a status update appears essential for future conservation and management strategies on a large scale. We provide an exhaustive update of the geographic range of the...

Campylopus introflexus is the only invasive moss listed among the 100 most prominent alien invaders in Europe. The present study shows dot distribution maps (at 10-years intervals from its introduction in 1986 to the present) and discusses the dynamics of its invasion, altitudinal distribution and ecological preferences. During the 30 years of its invasion, C. introflexus has spread widely throughout...

A rapid and nondestructive method to evaluate and visualize quality of vacuum packaged dry-cured sausages was developed using hyperspectral imaging (HSI) spectroscopy. Changes in physicochemical, microbiological and sensory attributes of the packaged dry-cured sausages were monitored during storage at 20°C. Discriminant factor analysis (DFA) could classify samples into different groups as a function...

Edible bird’s nest (EBN) is a precious functional food in Southeast Asia. A rapid and nondestructive method for determining the distribution map of protein content (PC), carbohydrate content (CC) and sialic acid content (SAC) on EBN sample was proposed. Firstly, 60 EBNs were used for hyperspectral image acquisition, and components content (PC, CC and SAC) were determined by chemical analytical methods...

Biological Invasions > 2016 > 18 > 11 > 3109-3116

Early detection of invasive alien species and the ability to track their spread are critical for undertaking appropriate management decisions. Citizen science surveys are potentially valuable tools for quickly obtaining information on biodiversity and species distributions. The Asian brown marmorated stink bug, Halyomorpha halys, is an invasive pest of agricultural crops and a dwelling nuisance. Halyomorpha halys...

Test node-based WCL algorithm for wireless sensor networks

Kwang-Yul Kim, Yoan Shin

2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN) > 418 - 423

2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)

From a system perspective, cost effectiveness and high-precision location information are important in wireless sensor networks (WSNs). Since a weighted centroid localization (WCL) algorithm can reduce hardware installation cost and guarantee localization accuracy, this algorithm is considered as one of the promising localization algorithms for WSNs. In this paper, we propose a test node-based WCL...

Katrin Zink, Pirmin Kaufmann, Blaise Petitpierre, Olivier Broennimann, more

International Journal of Biometeorology > 2017 > 61 > 1 > 23-33

One of the key input parameters for numerical pollen forecasts is the distribution of pollen sources. Generally, three different methodologies exist to assemble such distribution maps: (1) plant inventories, (2) land use data in combination with annual pollen counts, and (3) ecological modeling. We have used six exemplary maps for all of these methodologies to study their applicability and usefulness...
