Facilitating macrosystem biology with organismal‐scale airborne remote sensing: Challenges and opportunities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Emergent ecosystem properties, such as population and trait distributions, biodiversity and energy and water fluxes, occur because of the dynamic interactions of individuals in their environment.

High-Resolution Imaging Method of Deconvolution MIMO Sonar Based on Acoustic Homing Platform

水下无人系统学报
To address the demand for precise imaging of the desired guidance part of a target by an undersea vehicle, this paper attempted to apply multiple-input multiple-output(MIMO) sonar imaging to the acoustic homing platform of an underwater vehicle for the ...

STREETS AS STAGES: Traffic Enforcement and the Competition for Cultural Growth in China

International Journal of Urban and Regional Research, EarlyView.
ABSTRACT In keeping with China’s desire to build soft power to parallel its economic growth, the policing of city streets has moved to the forefront as a mechanism for moral regulation and improving urban prestige. Under pressure to civilize their citizenry, many Chinese cities have become entrepreneurial cities within a type of cultural growth ...

Identifying Purse Seine Vessel Operations Through Machine Learning Models for Better Spatial Fishing Effort Estimates

Fish and Fisheries, EarlyView.
ABSTRACT Spatial fisheries management requires precise, spatial explicit information on species distribution and fishing impacts. In the NW Mediterranean, the distribution of small pelagic fish (SPF) stocks is currently assessed through annual acoustic surveys.

Feature of Echo Envelope Fluctuation and Its Application in the Discrimination of Underwater Real Echo and Synthetic Echo

Applied Sciences, 2018
Discriminating a real underwater target echo from a synthetic echo is a key challenge to identifying an underwater target. The structure of an echo envelope contains information which closely relates to the physical parameters of the underwater target ...

Local Angler Knowledge Reveals Declines in Fishing Quality for Black Bass in Lakes of Eastern Ontario

Fisheries Management and Ecology, EarlyView.
ABSTRACT Local ecological knowledge can be useful to assess data‐limited fisheries such as the Ontario Black Bass (Micropterus spp.) recreational fishery. We surveyed local anglers using the Life History Calendar approach to determine if there were perceived changes in fishing quality for Black Bass in eastern Ontario across different time periods. For

Smartphone language and resting‐state EEG indicators of self‐focused attention prospectively predict major depressive disorder risk in adolescents

Journal of Child Psychology and Psychiatry, EarlyView.
Background Central to major depressive disorder (MDD) onset and maintenance is maladaptive self‐focused attention, which can be reliably indexed by greater: (a) usage of first‐person singular pronouns (e.g., I) in natural language and (b) alpha oscillations in resting‐state EEG.

Rapid increase in abundance and distribution of invasive pink salmon (Oncorhynchus gorbuscha) within a diverse, large Barents Sea catchment

Journal of Fish Biology, EarlyView.
Abstract Pink salmon originate from the North Pacific area but were introduced into northwest Russia from the late 1950s onwards. Since 2017, the alien species has increased dramatically in abundance and rapidly invaded adjacent areas of the North Atlantic region.
