Messy eaters: Swabbing prey DNA from the exterior of inconspicuous predators when foraging cannot be observed

open access: yesEcology and Evolution, 2019
Complex coevolutionary relationships among competitors, predators, and prey have shaped taxa diversity, life history strategies, and even the avian migratory patterns we see today.

Long‐Range Time‐Correlated Single‐Photon Counting Lidar 3D‐Reconstruction From a Moving Ground Vehicle

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Time‐correlated single‐photon counting (TCSPC) lidar enables high‐resolution 3D imaging at kilometer range. While previous works have covered long range TCSPC 3D imaging from either stationary or airborne platforms, this is, to the best of our knowledge, the first attempt that use a moving ground vehicle. Fusing measurements taken at different

[On the origin of the name Girifalco, an Italian town in a hotspot of the autumn migration of soaring raptors]

open access: yesNatural History Sciences
In this article, a hypothesis is suggested on the origin of the name Girifalco, a small town in the Calabrian Apennines (southern continental Italy), located along an important flyway of raptors migrating through the Central Mediterranean. In particular,

Spiral Approach for Non‐Software Product and Engineering System Development

open access: yesSystems Engineering, EarlyView.
ABSTRACT This article explored the spiral development process, sometimes called “evolutionary acquisition” in military sectors, and reviewed major non‐software applications in the engineering literature. The spiral development process was originally developed for the design of software while minimizing and managing risk, but the principles can be ...

Treatment of pressure gun fractures and release in the wild of a caracara (Caracara plancus)

open access: yesVeterinary Record Case Reports, EarlyView.
Abstract This report aims to describe the treatment progression of a free‐living southern crested caracara (Caracara plancus plancus) with gunshot‐related fractures. Radiographic examination revealed a comminuted fracture in the mid‐diaphysis of the humerus with displaced fragments, a comminuted fracture of the proximal third of the radius shaft, and ...

mTORC2 controls dendritic arbor development through Akt-mTORC1-p70S6K pathway

open access: yesFrontiers in Systems Neuroscience, 2014
Mammalian target of rapamycin (mTOR) is a serine/threonine protein kinase that was identified as one of the important regulators of dendritogenesis. mTOR forms two functionally separate complexes (mTORC) in mammalian cells.

Monitoring active osprey nests with drones is more time efficient and less disturbing than conventional methods

open access: yesWildlife Biology, EarlyView.
Drones are used to monitor bird nesting sites at less accessible locations, such as on cliffs, human infrastructure, or within the tree canopy. While there are a growing number of studies documenting avian behavioral responses to various drones, there is a continued need to monitor taxa‐specific responses to different drone models. We explored both the

A global review of the conservation status of true quails (Families Odontophoridae and Phasianidae)

open access: yesWildlife Biology, EarlyView.
Understanding the conservation status of species is imperative to stem global declines. To better inform conservation, we summarized the global conservation status of New World (Family Odontophoridae) and Old World (Family Phasianidae) true quail species.
