A Latitudinal Gradient of Reference Genomes

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Global inequality rooted in legacies of colonialism and uneven development can lead to systematic biases in scientific knowledge. In ecology and evolutionary biology, findings, funding and research effort are disproportionately concentrated at high latitudes, while biological diversity is concentrated at low latitudes.

Parallel algorithm for the matrix chain product problem [PDF]

open access: yes
This paper considers the problem of finding an optimal order of the multiplication chain of matrices. All parallel algorithms known use the dynamic programming approach and run in a polylogarithmic time using, in the best case, n6/log6n processors.

Talking About the Weather: The Feasibility of Using Very High‐Resolution Optical Satellite Imagery to Monitor Live and Stranded Cetaceans Around the UK and UK Overseas Territories

open access: yesMarine Mammal Science, EarlyView.
ABSTRACT Monitoring live and stranded cetaceans can be expensive and logistically challenging, resulting in knowledge gaps. Very high‐resolution (VHR) optical satellites are considered a potential solution to addressing some of these gaps. Despite success at detecting live and stranded cetaceans, satellites have only been trialed on restricted ...

Piles of Cubes, Monotone Path Polytopes and Hyperplane Arrangements

open access: yes, 1997
Monotone path polytopes arise as a special case of the construction of fiber polytopes, introduced by Billera and Sturmfels. A simple example is provided by the permutahedron, which is a monotone path polytope of the standard unit cube. The permutahedron

Ringed Seal (Pusa hispida) Abundance in Isfjorden, Svalbard, After 20‐Years of Climate Change and a Concomitant Survey Hiatus

open access: yesMarine Mammal Science, EarlyView.
ABSTRACT Ringed seals (Pusa hispida) in Svalbard, Norway, are suspected to be declining due to a significant reduction in land‐fast sea ice, which serves as an essential breeding habitat, but were last surveyed in 2002. We address this data gap by conducting Uncrewed Aerial Systems (UAS) aerial surveys throughout Isfjorden (including adjacent small ...

OrchardQuant‐3D: combining drone and LiDAR to perform scalable 3D phenotyping for characterising key canopy and floral traits in fruit orchards

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Orchard fruits such as pear and apple are important for ensuring global food security and agricultural economy as they not only provide essential nutrients, but also support biodiversity and ecosystem services. Breeders, growers and plant researchers constantly study desirable tree morphological features and floral characteristics to ensure ...
