Movement phases make a difference in habitat selection: Iberian lynx diversity of responses to human‐modified landscapes

open access: yesJournal of Animal Ecology, EarlyView.
By examining habitat selection across five movement phases in the reintroduced Iberian lynx, our study reveals high behavioural plasticity and key differences between and among resident and non‐resident phases. This research highlights the need to distinguish movement phases in habitat selection and landscape permeability studies to effectively guide ...

Exploratory study of transient upstart phenomena in a three-dimensional fixed-geometry scramjet engine [PDF]

open access: yes
The structural and thermal design of a hydrogen fueled regeneratively cooled three dimensional fixed geometry scramjet was examined. An exploratory study was conducted at Mach 5.3 in the 7-inch Mach 7 pilot tunnel to investigate the unstart phenomena and

From cities to refuges for pollinators: Urban practices for enhancing pollinator habitats in changing landscapes

open access: yesJournal of Applied Ecology, EarlyView.
A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,

Transonic flutter study of a 50.5 deg cropped-delta wing with two rearward-mounted nacelles [PDF]

open access: yes
Transonic flutter characteristics of three geometrically similar delta-wing models were experimentally determined in the Langley transonic dynamics tunnel at Mach numbers from about 0.6 to 1.2.

Entwined Liberations: North Korean Democratic Women's Union and Third World Internationalism, 1945–1949

open access: yesGender &History, EarlyView.
ABSTRACT This research focuses on how the North Korean Democratic Women's Union (NKDWU), the umbrella women's organisation in North Korea formed soon after Korea's liberation from Japanese colonial rule in 1945, forged international leftist women's solidarity during the North Korean state's liminal, revolutionary period (1945–1949).

Observation Bias in Metabarcoding

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT DNA metabarcoding is subject to observation bias associated with PCR and sequencing, which can result in observed read proportions differing from actual species proportions in the DNA extract. Here, we amplify and sequence a mock community of known composition containing marine fishes and cetaceans using four different primer sets and a ...
