wet 4-week intervals. For butterfly species that exist in high enough densities, we recommend using point transect distance sampling in habitats where traditional methods are impossible to implement. J ...
butterfly diversity surveys and population monitoring in complex tropical landscapes. Due to methodological flexibility and simplicity, this method may be particularly useful to study the impacts of climate ...
. Such discoveries have been possible because of standardised methods , such as line transects , of counting butterflies and other insects. However, line transects are not feasible in many tropical and mountainous ...
Abstract Many methods are used to survey butterfly populations, with line transect and area surveys being prominent. Observers are typically limited to search within 5 or 10 m from the line, while ...
biology in school. The method used in this study is the roami ng method . Determination of sampling locations is done by purposive sampling method . Sampling was carried out by following a 500m transect line ...
of the currently used methods and suggest potential refinements, based on methodological advances achieved in other organisms. While assessing butterfly distribution, it is vital to account for imperfect species ...
approach, we studied butterfly diversity and community structure in the dryland savannah biome of south-eastern Kenya with two different methods , transect counts and bait trapping. We repeatedly collected ...
methods are still currently used in butterfly research, with trapping, netting, and mark-recapture used in 85% of studies . Over the last century, the amount of butterfly research has steadily increased, so ...
underrepresented in the data set, leading to less information about the butterfly populations there. In the present study , we in - vestigate the possibility of applying a spatial design used by the Swedish Bird ...
The butterfly assemblages of pairs of forest habitats, differing in disturbance level, within the Victoria Mayaro reserve of South-East Trinidad, are described using walk-and-count transects ...
