چکیده

A simple model of animal movement on random and patterned landscapes was used to explore the problems of extrapolating information across a range of spatial scales. Simulation results indicate that simple relationships between pattern and process will produce a variety of scale-dependent effects. These theoretical studies can be used to design experiments for determining the nature of scale-dependent processes and to estimate parameters for extrapolating information across scales.

'You shall not pass!': quantifying barrier permeability and proximity avoidance by animals.

Impediments to animal movement are ubiquitous and vary widely in both scale and permeability. It is essential to understand how impediments alter ecological dynamics via their influence on animal behavioural strategies governing space use and, for anthropogenic features such as roads and fences, how to mitigate these effects to effectively manage species and landscapes. Here, we focused primari...

Quantifying drivers of wild pig movement across multiple spatial and temporal scales

BACKGROUND The movement behavior of an animal is determined by extrinsic and intrinsic factors that operate at multiple spatio-temporal scales, yet much of our knowledge of animal movement comes from studies that examine only one or two scales concurrently. Understanding the drivers of animal movement across multiple scales is crucial for understanding the fundamentals of movement ecology, pred...

Tortuosity Entropy: a measure of spatial complexity of behavioral changes in animal movement data

The goal of animal movement analysis is to understand how organisms explore and exploit complex and varying environments. Animals usually exhibit varied and complicated movements, from apparently deterministic behaviours to highly random behaviours. It has been a common method to assess movement efficiency and foraging strategies by means of quantifying and analyzing movement trajectories. Here...

Concentration dependent effect of morphine, aspirin, capsaicin and chili pepper hydro alcoholic extract on thermal and chemical pain model in fruit fly (Drosophila melanogaster)

Introduction: Pain research using animal models is related to ethical concerns, so invertebrates and insects have been recommended by researchers. In the present study, the nociceptive and antinociceptive effects of capsaicin, aspirin, morphine and chili extract were examined using fruit fly (Drosophila melanogaster) as an alternative for rodent pain model. Methods: Stage 3 of larvae and ad...

Quantifying hydrological effects of crop diversification in Northern Iran paddy fields

There are human and animal health concerns related to drainage systems because nutrients, especially nitrogen and phosphorus, can contaminate water supplies. A field study was conducted on consolidated paddy fields of Sari Agricultural Sciences and Natural Resources University, Northern Iran (36.3°N, 53.04°E), to determine the effect of subsurface drain depth and spacing on nitrogen (N) and pho...
