Abstract.  1. Wet heathlands and closely associated habitats (e.g. bogs and poor fens) have been highly fragmented over the last two centuries. These habitats nowadays benefit from large‐scale restoration projects, for which the success should be evaluated. 
Effect of habitat spatiotemporal structure on collembolan diversity
Combined effects of area, connectivity, history and structural heterogeneity of woodlands on the species richness of hoverflies (Diptera: Syrphidae)
These findings emphasise the importance of maintaining connectedness between woodlands, which facilitates the dispersion in a changing landscape, and highlight the benefits of using a change-oriented approach to explain the current distribution patterns of species.
The Ecological Processes that Underpin Ecological Restoration
In this article, the importance of these major ecological theories and how relevant they are in restorations today are evaluated.
Imperfect detection biases extinction‐debt assessments
Freshwater ecosystems have been substantially altered, threatening the survival and recovery of aquatic species at risk. Estimating the likelihood and magnitude of future extinctions (extinction
Temporal effects of organic farming on biodiversity and ecosystem services
Agricultural intensification has caused a dramatic decline of global biodiversity and associated ecosystem services. Organic farming has been shown to partially counteract agricultural
Ecological time lags and the journey towards conservation success
The proposal for setting and evaluating conservation targets is to use milestones, or interim targets linked to specific ecological mechanisms at key points in time, to assess whether conservation actions are likely to be working and to accounting for ecological time lags in biodiversity targets and indicators.

Plant species richness and composition of heathland relics in north‐western Belgium: evidence for a rescue‐effect?
The effects of the degree of fragmentation of heathland patches on their species richness and species composition are studied, and the ecological mechanisms behind the observed patterns are inferred.
Colonization Credit in Restored Wet Heathlands
The concept of "colonization credit" (i.e., the number of species yet to colonize a patch, following landscaping changes) is used as a framework to evaluate the success of colonization, in terms of species richness, in new/ restored habitats, taking into account the spatial structure of landscapes.

Habitat quality is the missing third parameter in metapopulation dynamics, contributing more to species persistence, than site area or isolation, and a reorientation in conservation priorities is recommended.
Local population dynamics are important to the conservation of metapopulations in highly fragmented landscapes
1. Population viability analyses (PVA) are extremely useful tools for the management of endangered species at the landscape scale. Two main families of spatially explicit models are available to
Data indicate that spatial configuration is important to mitigate extinction risks when habitat availability in a landscape is low, whereas no effect will be observed when overall area of habitat is high.
Effects of vegetation structure and floristic diversity on detritivore, herbivore and predatory invertebrates within calcareous grasslands
Investigation of the impact of military vehicle activity, floral species richness and vegetation structure on assemblages of detritivore, herbivore and predatory invertebrates finds the need for variety in the timing and type of management applied to promote heterogeneity in sward structure is emphasised.

It is suggested that the surrounding matrix can significantly influence the “effective isolation” of habitat patches, rendering them more or less isolated than simple distance or classic models would indicate.
