Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Effect of Resonant Mixer Granulation Parameters on Prill Properties

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Resonant mixing is a promising processing approach to manage mixing of materials with high solids content and has shown strong performance for mixing powders and pastes in energetic materials. This has led to the exploration of the approach for granulation of primary particles into millimeter‐sized agglomerates, including for generating ...

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Historical remote sensing highlights long‐term persistence of Emperor Penguin (Aptenodytes forsteri) colonies

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Remote sensing can reveal population dynamics of Antarctic penguin colonies. In this study, we analyze emperor penguin (Aptenodytes forsteri) guano stains in remote sensing imagery and discover colony presence predating known records for 18 colonies across Antarctica.

Citizen Science for Individual Identification of Pine Martens Martes martes From Camera Trap Footage

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera traps generate large volumes of wildlife footage, but identifying animals to the individual level remains challenging and time‐consuming. Using European pine martens in the Forest of Dean as a case study, we assessed whether citizen scientists could identify individuals from camera trap photos and videos.

Improving Demographics and Conservation of Fishes Through Multi‐Frame Individual Distinctions by Size (MIDS)

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
MIDS (Multi‐frame Individual Distinctions by Size) is a new software package for improving how fish populations are assessed using stereo‐video data. By using the length, error and statistical inference of measurements, MIDS distinguishes individuals across multiple video frames and autonomously removes repeat observations, regardless of when the ...
