Fluctuation Domains in Adaptive Evolution

open access: yes, 2010
We derive an expression for the variation between parallel trajectories in phenotypic evolution, extending the well known result that predicts the mean evolutionary path in adaptive dynamics or quantitative genetics.

Randomly pinned landscape evolution

open access: yesPhysical Review E, 1997
A simple scheme for the evolution of a fluvial landscape in heterogeneous environments is critically examined to capture the essential mechanism responsible for the recurrent scale-free landforms in the river basin. It is shown that, regardless of boundary and initial conditions, geomorphological constraints in the form of quenched randomly pinned ...

How political parties adjust to fixed voter opinions

open access: yes, 2005
We propose a new version of the spatial model of voting. Platforms of five parties are evolving in a two-dimensional landscape of political issues so as to get maximal numbers of voters.

Tephra data from varved lakes of the Last Glacial–Interglacial Transition: towards a global inventory and better chronologies on the Varved Sediments Database (VARDA) [PDF]

open access: yesEarth System Science Data
The Varved Sediments Database (VARDA) was launched in 2020 and aimed to establish a community database for annually resolved chronological archives with their associated high-resolution proxy records.

The Multidisciplinary Approach in the Study of Landscape Evolution: The Fluvial Capture of the San Donato Creek (Gubbio, Central Italy), an Example of Hydrological Regime and Hydrogeological Risk Changes

open access: yesLand, 2023
Historical maps, especially those at a small scale and rich in detail (e.g., the old “Cadastres”), represent an exceptionally important tool for understanding the recent historical evolution of landscapes.

Effective Fitness Landscapes for Evolutionary Systems

open access: yes, 1999
In evolution theory the concept of a fitness landscape has played an important role, evolution itself being portrayed as a hill-climbing process on a rugged landscape.

ORDNA: Deep‐learning‐based ordination for raw environmental DNA samples

open access: yesMethods in Ecology and Evolution
Environmental DNA (eDNA) metabarcoding has revolutionized biodiversity monitoring, offering non‐invasive tools to assess ecosystem health. The complexity of eDNA metabarcoding data poses major challenges for conventional ordination methods in ...

Consideration of landscape in the framework documentation during the evolution of the Rural Environment Protection Scheme (REPS) in the Republic of Ireland. [PDF]

open access: yes, 2010
working paperThis paper looks at the changing concept of landscape during the evolution of REPS. It reviews and groups definitions of landscape and identifies their agri-environmental relevance.

Dynamics of Competitive Evolution on a Smooth Landscape

open access: yes, 2003
We study competitive DNA sequence evolution directed by {\it in vitro} protein binding. The steady-state dynamics of this process is well described by a shape-preserving pulse which decelerates and eventually reaches equilibrium.
