Ten years of the resource-based habitat paradigm: the biotope-habitat issue and implications for conserving butterfly diversity

Abstract: Abstract:The widely used term 'habitat' underlies all aspects of a species' (and community's) population size, consequently population changes, distribution and range size and changes; ultimately, habitat parameters determine the status of species, whether thriving or threatened with extinction. Habitat parameters also lie at the root of species' evolution (speciation) involving cycles of resource specialism/generalism. A basic problem is that habitat has long been treated as synonymous with biotope. But, the … Show more

“…These traits are all indicative of a strong ecological interaction between the butterfly and host plant, with individual butterflies completing their entire life cycle in a restricted area, hence the strength of the statistical relationship linking plant and butterfly abundance. By contrast, individual butterflies in species with the opposite set of traits (polyphagy and mobility) experience only weak interactions with the plant population on which they fed as larvae (Dennis, Dapporto & Dover ). Polyphagy allows adult butterflies to select oviposition sites from a range of host plant species; mobility allows butterflies to travel between habitat patches in order to reproduce.…”

“…These studies reveal that some species show open population structure, with individuals roaming widely across diverse habitats, seeking mates, nectar sources and oviposition sites as they fly. For these butterflies the term ''habitat patch'' may not be meaningful (Dennis et al 2003(Dennis et al , 2014. However, most butterflies, including those studied here, occur in discrete populations occupying habitat patches comprising areas of distinct vegetational and physical structure covering hundreds to thousands of square metres.…”

“…Behavioural trait data are only currently being aggregated (e.g. Dennis et al, 2014) with Dennis (2010), giving the most comprehensive set of behavioural information. Highly congruent data types-wingspan, voltinism and overwintering stage-are either traits that have been well documented from the early 20 th century (e.g.…”

“…Other traits can be more problematic. “Habitat” is also a commonly used trait in many analyses; despite often lacking a precise definition in many studies (cf., Dennis, Dapporto, & Dover, ; Dennis, Shreeve, & Van Dyck, ); there is a tendency to associate “habitat” with loosely defined biotopes. If defined as a vegetation association, “habitat” is not consistent with resource requirements, which are frequently more precise (e.g.…”
