Cameras do not always take a full picture: wolf activity patterns revealed by accelerometers versus road‐positioned camera traps

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera traps have become an increasingly popular non‐invasive alternative to animal‐attached devices for studying wildlife behaviour. This study compared wolf (Canis lupus) activity patterns derived from collar accelerometers and road‐positioned camera traps and revealed strong overall agreement but also important seasonal and diel mismatches between ...

From snapshots to continuous estimates: Augmenting citizen science with computer vision for fish monitoring

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study presents an end‐to‐end computer‐vision pipeline for monitoring fish migration using underwater video. We integrate field camera deployment, annotation, model training and automated in‐season counting to generate continuous, high‐resolution data on river herring spawning migration.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Dispersive Calculation of the Massless Multi-loop Sunrise Diagram [PDF]

open access: yes, 2018
The massless sunrise diagram with an arbitrary number of loops is calculated in a simple but formal manner. The result is then verified by rigorous mathematical treatment. Pitfalls in the calculation with distributions are highlighted and explained.

Characteristics of unique cap, Tsurushi and Hata clouds around Mount Fuji

open access: yesWeather, EarlyView.
Distinct clouds, such as cap clouds, Tsurushi (a type of lenticular cloud) and Hata (banner cloud‐like clouds), frequently form around Mount Fuji, an isolated peak with a slightly elliptical conical shape. Here, we examine their characteristics and occurrence patterns.

Diurnal variation of overdense meteor echo duration and ozone [PDF]

open access: yes
The diurnal variation of the median duration of overdense sporadic radar meteor echoes is examined. The meteors recorded in August, December, and January by the Ondrejov meteor radar during the period 1958-1990 were used for the analysis.

Unraveling the impact of dog‐friendly spaces on urban–wildland pumas and other wildlife

open access: yesWildlife Biology, EarlyView.
As the most widespread large carnivore on the planet, domestic dogs Canis lupus familiaris can pose a major threat to wildlife, even within protected areas (PAs). Growing human presence in PAs, coupled with increasing pet dog ownership underscores the urgency to understand the influence of dogs on wildlife activity and health.
