We assessed the impact of vegetation structure and type of landscape on microclimatic conditions for flight activity, using the heliothermic butterfly Pararge aegeria as a model. Dummies (i.e., dead specimens with spread wings, on a hypodermic needle with a thermocouple) that initially were warmed up to similar thorax temperatures were able to cover larger distances, and they heated up faster, wit...<br/><br/>T Merckx, S Van Dongen, E Matthysen, H Van Dyck (2008) <i>BASIC AND APPLIED ECOLOGY</i> 9: 4 433-442<br/>

1. Substantial declines have been documented in many of the so called ‘common’ macro-moth species in the UK. One cause of this decline is the intensification of agriculture and, in response to this, Environmental Stewardship schemes are now offering the opportunity to restore agricultural habitats to provide landscapes for macro-moths and other wildlife. 2. In this study the habitat use of 11...<br/><br/>R L Dulieu, T Merckx, N Paling, G Holloway (2007) <br/>

The ability of an organism to find new habitat is likely to contribute to dispersal success in different landscapes. We compared the ability of male speckled wood butterflies from two types of landscape to orientate towards forested habitat as a behavioural assay of the ability to perceive forested habitat at a distance (25-200 m). This field release-experiment showed that butterflies of fragmente...<br/><br/>T Merckx, H Van Dyck (2007) <i>ANIMAL BEHAVIOUR</i> 74: 4 1029-1037<br/>

1. The intensification of agriculture throughout Europe, and the rest of the world indeed, has been identified as an important threat to wildlife. In order to halt the decline of biodiversity in European farmland, agri-environment (AE) schemes have been introduced. These governmental schemes financially compensate farmers to manage their land in an environmentally-friendly manner. There is some co...<br/><br/>P G J Ward (2007) <br/>

1. Active time budgets of flying ectotherms depend on body temperature. Knowledge of flight ability and performance is currently heavily biased towards the range of temperatures favourable for voluntary flight activity. Flight under suboptimal temperature conditions may also be important, however, in terms of fitness. 2. Here we study the ability of organisms to fly at body temperatures colder ...<br/><br/>T Merckx, B Karlsson, H Van Dyck (2006) <i>FUNCTIONAL ECOLOGY</i> 20: 34 436-441<br/>

In evolutionary time, varying environments may lead to different morphs as a result of genetic adaptation and divergence or phenotypic plasticity. Landscapes that differ in the extent of habitat fragmentation may provide different selection regimes for dispersal, but also for other ecological functions. Several studies on flying insects have shown differences in flight morphology between landscape...<br/><br/>T Merckx, H Van Dyck (2006) <i>OIKOS</i> 113: 52 226-232<br/>

Populations of British butterflies and moths, including Brown hairstreak (Thecla betulae) and Blue bordered carpet (Plemyria rubiginata), have declined dramatically in the United Kingdom over the past 50 years. These and other butterflies rely on hedgerows as habitats, but unfortunately, over 50% of hedgerows have been removed since 1945. Hedgerow management is therefore crucial for the conservati...<br/><br/>F Van Kesteren (2006) <br/>

This thesis has an evolutionary ecological focus, investigating how organisms cope with changing environments. More specifically, this work addresses the intriguing and timely issue of differing life history traits (including functional morphology and behaviour) in landscapes where an organism’s habitat gets fragmented. Habitat fragmentation is widely recognised as a key problem for biodiversity...<br/><br/>T Merckx (2005) <br/>

Visually cued mate location behaviour in insects such as butterflies is typically classified by 'wait or seek' dichotomies. Perching males adopt a sit-and-wait strategy at a particular spot rising to intercept passing females (which is often done in an aggressive territorial way), whereas patrolling males are permanently on the wing searching for females. The potential influence of changes in land...<br/><br/>T Merckx, H Van Dyck (2005) <i>ANIMAL BEHAVIOUR</i> 70: 38 411-416<br/>

Butterfly diversity has declined from 64 to 45 species in Flanders (north-Belgium) during the 20th century. Biotope loss, fragmentation and eutrophication are the main causes of these extinctions. Despite the fact that the total woodland area remained stable in Flanders during the last century, many typical woodland butterflies went extinct. The loss of habitat quality due to more intensive woodla...<br/><br/>D Gorissen, T Merckx, B Vercoutere, D Maes (2004) <i>LANDSCHAP - JOURNAL FOR LANDSCAPE ECOLOGY AND ENVIRONMENTAL SCIENCE IN FLANDERS AND THE NETHERLANDS</i> 21: 2 85-95<br/>

As landscapes change, mobility patterns of species may alter. Different mechanistic scenarios may, however, lead to particular patterns. Here, we tested conflicting predictions from two hypotheses on butterfly movements in relation to habitat fragmentation. According to the resource distribution hypothesis, butterflies in more fragmented landscapes would have higher levels of mobility as resources...<br/><br/>T Merckx, H Van Dyck, B Karlsson, O Leimar (2003) <i>PROCEEDINGS OF THE ROYAL SOCIETY OF LONDON SERIES B-BIOLOGICAL SCIENCES</i> 270: 36 1815-1821<br/>

Mobility, activity patterns, habitat use, and some morphological traits of two often cooccurring satyrine butterflies of grasslands-the meadow brown (Maniola jurtina) and the hedge brown (Pyronia tithonus)-were studied by a mark-release-recapture method at two sites. Additionally, someflight-related morphological traits of a series of collected females of P. tithonus were compared between recently...<br/><br/>T Merckx, H Van Dyck (2002) <i>JOURNAL OF INSECT BEHAVIOR</i> 15: 32 541-561<br/>
