Evolutionary connectionism: algorithmic principles underlying the evolution of biological organisation in evo-devo, evo-eco and evolutionary transitions [PDF]

open access: yes, 2015
The mechanisms of variation, selection and inheritance, on which evolution by natural selection depends, are not fixed over evolutionary time. Current evolutionary biology is increasingly focussed on understanding how the evolution of developmental ...

Sinking Versus Suspended Particle Size Distributions in the North Pacific Subtropical Gyre

open access: yesGeophysical Research Letters, 2020
The particle size distribution (PSD) is a fundamental property that influences all aspects of phytoplankton ecology. In particular, the size (e.g., diameter d [μm]) and sinking speed w (m/day) of individual particles are inextricable, but much remains ...

A Lagrangian model of copepod dynamics: Clustering by escape jumps in turbulence [PDF]

open access: yes, 2016
Planktonic copepods are small crustaceans that have the ability to swim by quick powerful jumps. Such an aptness is used to escape from high shear regions, which may be caused either by flow per- turbations, produced by a large predator (i.e., fish ...

Density-and trait-mediated effects of a parasite and a predator in a tri-trophic food web [PDF]

open access: yes, 2014
1. Despite growing interest in ecological consequences of parasitism in food webs, relatively little is known about effects of parasites on long-term population dynamics of non-host species or about whether such effects are density- or trait- mediated ...

Evolutionary Fields Can Explain Patterns of High Dimensional Complexity in Ecology [PDF]

open access: yesPhys. Rev. E 95, 042401 (2017), 2016
One of the properties that make ecological systems so unique is the range of complex behavioural patterns that can be exhibited by even the simplest communities with only a few species. Much of this complexity is commonly attributed to stochastic factors which have very high-degrees of freedom.

Spatial patterns of competing random walkers [PDF]

open access: yes, 2014
We review recent results obtained from simple individual-based models of biological competition in which birth and death rates of an organism depend on the presence of other competing organisms close to it.

Single virus genomics: a new tool for virus discovery.

open access: yesPLoS ONE, 2011
Whole genome amplification and sequencing of single microbial cells has significantly influenced genomics and microbial ecology by facilitating direct recovery of reference genome data.

Isotopic constraints on the atmospheric sources and formation of nitrogenous species in clouds influenced by biomass burning [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Predicting tropospheric cloud formation and subsequent nutrient deposition relies on understanding the sources and processes affecting aerosol constituents of the atmosphere that are preserved in cloud water.

The challenges, uncertainties and opportunities of bioaerosol dispersion modelling from open composting facilities [PDF]

open access: yes, 2017
Bioaerosols are ubiquitous organic particles that comprise viruses, bacteria and coarser fractions of organic matter. Known to adversely affect human health, the impact of bioaerosols on a population often manifests as outbreaks of illnesses such as ...

A Hybrid Particle Swarm Optimisation-Genetic Algorithm for Multi-objective Reservoir Ecological Dispatching

open access: yesWater Resources Management, 2022
Abstract Reservoir ecological dispatching is a complex system problem with multi-objective, multiple-criteria and multiple-phase. This study establishes a multi-objective ecological dispatching model in Changchun city of Yinma River Basin based on the water demand of social economic development, river ecology, and the constraint of reservoir ...
