Radial basis function based meshless methods for fluid flow problems

open access: yes, 2006
This thesis is concerned with the development of meshless methods using radial basis functions for solving fluid flow problems. The advantage of meshless methods over traditional mesh-based methods is that they make use of a scattered set of collocation ...

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Acclimatisation duration, not just release type, drives post‐release settlement in a large‐scale carnivore reintroduction programme

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...

Forest cover drives bird occupancy across guilds and habitats in a Colombian coffee‐farming landscape

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Increasing landscape forest cover would improve occupancy for nearly all bird guilds using coffee and forest habitats in the Eastern Colombian Andes. Conserving forest and enhancing shade coffee are complementary–not interchangeable–strategies: landscape forest cover shapes the conditions under which farm‐scale habitat management can sustain diverse ...

Representativeness of the Natura 2000 network for preserving plant biodiversity in the European Union

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract The Natura 2000 (N2K) network of protected areas is one of the main tools for area‐based conservation in the European Union (EU), yet its role in preserving plant biodiversity requires better understanding. We examined data kept in the European Vegetation Archive from over 1.2 million vegetation plots and obtained over 14.2 million plant ...
