Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Mesh design for electrical resistivity imaging of agricultural dikes

Near Surface Geophysics, EarlyView.
Abstract Electrical resistivity imaging (ERI) shows promise for investigating earthen flood barriers. We are interested in the applicability of ERI for aiding maintenance and construction efforts on agricultural dikes in the upper Bay of Fundy, Canada.

Revolution-bump mapping with texture function adjustment according to the geometry of the revolved object

Journal of Graphic Engineering and Design
Nowadays, 3D computer graphics are firmly anchored in our daily lives, extending across a multitude of distinct fields. Although each field follows its specific objectives, two major objectives are taken into consideration: realism and rendering speed ...

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

River Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Accounting for animal movement during aerial imaging surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections

Structural Concrete, EarlyView.
Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

Artificial light at night and invasive signal crayfish alter aquatic‐terrestrial food webs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Resource flows across aquatic‐terrestrial boundaries are increasingly affected by multiple stressors, such as artificial light at night (ALAN) and aquatic invasive species, which can alter the availability of resources for consumers.

A Novel Multidisciplinary Approach for Reptile Movement and Behavior Analysis

Integrative Zoology, EarlyView.
We present a novel multidisciplinary approach capable of advancing research on reptiles’ behavior. Our approach uses integrated tools and methods for the digitization, reconstruction, and visualization of reptiles and their behavior. We (i) record movement through tri‐axial accelerometers, video cameras, and motion capture systems; (ii) ground‐truth ...
