Planning for urban biodiversity on shifting social–ecological grounds: Insights from Narrm‐Melbourne, Australia

open access: yesEcological Solutions and Evidence
Narrm‐Melbourne, Australia, has been at the forefront of urban biodiversity research, planning and management for 50 years in urban landscapes that have many endemic and threatened species and remnant ecosystems.

Influence of landscape structure and human modifications on insect biomass and bat foraging activity in an urban landscape.

open access: yesPLoS ONE, 2012
Urban landscapes are often located in biologically diverse, productive regions. As such, urbanization may have dramatic consequences for this diversity, largely due to changes in the structure and function of urban communities.

Multidimensional Epistasis and the Advantage of Sex

open access: yes, 2005
Kondrashov and Kondrashov (2001) suggest that there is usually a disadvantage for sex in systems with multidimensional epistasis. They define systems of 'unidimensional epistasis' to be those where the fitness of a genotype is a function of the number of

Efficiency of quantum versus classical annealing in non-convex learning problems

open access: yes, 2017
Quantum annealers aim at solving non-convex optimization problems by exploiting cooperative tunneling effects to escape local minima. The underlying idea consists in designing a classical energy function whose ground states are the sought optimal ...

Environmental Drivers of NDVI-Based Vegetation Phenology in Central Asia

open access: yesRemote Sensing, 2011
Through the application and use of geospatial data, this study aimed to detect and characterize some of the key environmental drivers contributing to landscape-scale vegetation response patterns in Central Asia.

The evolutionary landscape of functional model proteins [PDF]

open access: yesProtein Engineering, Design and Selection, 1999
To study the distinct influences of structure and function on evolution, we propose a minimalist model for proteins with binding pockets, called functional model proteins, based on a shifted-HP model on a two-dimensional square lattice. These model proteins are not maximally compact and contain an empty lattice site surrounded by at least three nearest

Robustness and epistasis in mutation-selection models

open access: yes, 2009
We investigate the fitness advantage associated with the robustness of a phenotype against deleterious mutations using deterministic mutation-selection models of quasispecies type equipped with a mesa shaped fitness landscape.

Large-effect flowering time mutations reveal conditionally adaptive paths through fitness landscapes in Arabidopsis thaliana. [PDF]

open access: yes, 2019
Contrary to previous assumptions that most mutations are deleterious, there is increasing evidence for persistence of large-effect mutations in natural populations.

Landscape patterns of primary production reveal agricultural benefits from forest conservation

open access: yesPerspectives in Ecology and Conservation, 2019
Primary production (PP) is a fundamental ecosystem function that influences several ecosystem services. However, little is known about how changes in landscape structure resulting from agricultural expansion affects forest and cropland production.
