Abstract In this study, we develop an extended multi-objective mixed integer programming (EMOMIP) approach for water resources management under uncertainty, in which the parameters are fuzzy random variables while the decision variables are interval variables. Furthermore, some alternatives are considered to retrieve the difference between the quantities of promised water-allocation targets and the actual allocated water. Then, the proposed EMOMIP for the problem is solved by a new method using ...

Abstract Animal communication impacts many kinds of behavior including mating and courtship, escaping from predators and foraging activity. In this article, our investigation focuses primarily on how alarm communication impacts foraging activity, using individual based computer simulations. We used this approach to help resolve a debate in the literature between the risk-allocation hypothesis, which predicts that over time, animals become habituated to alarm communication versus the hypothesis t...

Abstract Technological innovations have expanded our ability to understand ecological systems and conserve biodiversity at a time when many species are at risk from climate change and habitat loss. One technology that is predicted to greatly benefit the field of avian ecology is the microcomputer. Raspberry Pi microcomputers are low-cost alternatives to personal computers and are able to house a variety of environmental sensors. Raspberry Pis have recently been used to monitor the behavior of bi...

Abstract Assessing biodiversity in arctic-alpine ecosystems is a costly task. We test in the current study whether we can map the spatial patterns of spider alpha and beta diversity using remotely-sensed surface reflectance and topography in a heterogeneous alpine environment in Central Norway. This proof-of-concept study may provide a tool for an assessment of arthropod communities in remote study areas. Data on arthropod species distribution and richness were collected through pitfall trapping...

Abstract Terrain attributes (e.g., slope, rugosity) derived in Geographic Information Systems (GIS) from digital terrain models (DTMs) are widely used in both terrestrial and marine ecological studies due to their potential to act as surrogates of species distribution. However, the spatial resolution of DTMs is often altered to match the scale at which species observations were collected. Here, we highlight the significance of adequately reporting the methods used to derive terrain attributes fr...

Abstract Climatic niche modeling is widely used in modern macroecology and evolutionary biology to model species' distributions and ecological niches. Frequently, Global Biodiversity Information Facility (GBIF) distribution data are used as raw data for such models. Unfortunately, the accuracy of resulting niche estimates is difficult to assess, and GBIF users continue to call for a better understanding of GBIF data precision and uncertainty. Our research evaluates how GBIF data perform in compa...

Abstract Inspired by that bird sound has various frequency distributions and continuous time-varying properties, a novel method is proposed for the classification of bird sound based on continuous frame sequence and spectrogram-frame linear networks (SFLN). In order to form a continuous frame sequence as the standard input for SFLN, a sliding window algorithm of short frame length is suitable for differentiate the Mel-spectrogram of bird sound. The vertical 3D filter in the linear layer moves li...

Abstract There is consensus surrounding the need to include a third dimension when estimating Species Distribution Models (SDMs), which is of special interest for marine species. Application of the third dimension is, however, rarely available, thus users are obliged to manually combine 2D SDM outputs (i.e., suitability or presence/absence maps) for 3D distribution generation. Herein, the Niche of Occurrence 3D (NOO3D) is presented, which is a new, simple modelling procedure that provides 3D dis...

Abstract Extreme-flow events have been a central point of interest in hydrology and recent developments suggest that their role could be critical in the overall functioning of watershed systems. The development of modelling techniques that can effectively reproduce the hydrological dynamics of watersheds during extreme events is one of the challenges of the contemporary modelling practice. In this study, we present a season-specific, multi-site calibration framework that accommodates the variabi...

Abstract Malaria is a vector-borne disease that is considered a major public health problem in tropical and semi-tropical areas. The transmission of malaria is associated with the interactions among environment, Anopheles mosquitoes (vectors), and humans (hosts). Plasmodium vivax is one of the four species of malaria parasites that commonly infect humans in Asia, Latin America, and in some parts of Africa. The major difference between this and other parasites is the recurrence of malaria. The ma...
