Habitat quality and metapopulation effects are the main hypotheses that currently explain the disproportionate decline of insects in cultivated Holarctic landscapes. The former assumes a degradation in habitat quality for insects within surviving ecosystems, the latter that too few, small or isolated islands of ecosystem remain in landscapes for populations to persist. These hypotheses are often treated as alternatives, and this can lead to serious conflict in the interpretations of…

Connectivity compensates for low habitat quality and small patch size in the butterfly Cupido minimus

TLDR
Concerning long-term survival of (meta-) populations in fragmented landscapes, the results show that lower habitat quality may be compensated by higher connectivity between host plant patches, and internal and temporal validation demonstrate the stability and robustness of the developed habitat models.

Determinants of extinction-colonization dynamics in Mediterranean butterflies: the role of landscape, climate and local habitat features.

TLDR
Using multiseason occupancy models, which take into account species' detectability, robust estimates of local extinction and colonization probabilities for each species are obtained and the potential effects of site covariates such as the area of suitable habitat, topographic variability, landscape permeability around the site and climatic variability in aridity conditions are tested.

THE ECOLOGICAL FACTORS GOVERNING THE PERSISTENCE OF BUTTERFLIES IN URBAN AREAS

Previous studies have suggested that availability of high quality habitat rather than habitat connectivity or species mobility was the limiting factor in the distribution of grassland butterflies,

How do local habitat management and landscape structure at different spatial scales affect fritillary butterfly distribution on fragmented wetlands?

Habitat fragmentation, patch quality and landscape structure are important predictors for species richness. However, conservation strategies targeting single species mainly focus on habitat patches

How Do Landscape Structure, Management and Habitat Quality Drive the Colonization of Habitat Patches by the Dryad Butterfly (Lepidoptera: Satyrinae) in Fragmented Grassland?

TLDR
It is concluded that dryad colonization of the study area is very recent, since the most important factor limiting colonization was distance from the refugium, while the habitat quality of target patches had less relevance.

Patch occupancy in the endangered butterfly Lycaena helle in a fragmented landscape: effects of habitat quality, patch size and isolation

TLDR
Patch occupancy in the violet copper Lycaena helle, one of the rarest butterfly species in Central Europe, is investigated in the Westerwald area (Rhineland-Palatinate, Western Germany) and suggests that even for extremely sedentary species such as L. helle habitat networks are decisive and need to be an integral part of any conservation management for this species.

The role of habitat quality in fragmented landscapes: a conceptual overview and prospectus for future research

TLDR
It is shown how a weak conceptualization of “patch quality” and the inappropriate choice of target surrogate variables have mainly produced case-specific results, rather than general conclusions, and weaknesses in the inclusion of habitat quality measurements within fragmentation studies are identified.

Potential metapopulation structure and the effects of habitat quality on population size of the endangered False Ringlet butterfly

TLDR
The results suggest that the long-term preservation of the studied metapopulation needs the maintenance of high quality habitat patches by appropriate mowing regime and water regulation, and management also should facilitate dispersal to strengthen metAPopulation structure with creating stepping-stones or gradually increase habitat quality in present matrix.

The effects of spatial patterns in habitat quality on community dynamics within a site

TLDR
It is found that the ant species that acts as host to the butterfly caterpillars decreased with site ruggedness, and the impact on the butterfly was more substantial: it often failed to persist on very rugged sites.

The metapopulation capacity of a fragmented landscape

TLDR
The metapopulation capacity is introduced, a new measure for highly fragmented landscapes, which is rigorously derived from metAPopulation theory and can easily be applied to real networks of habitat fragments with known areas and connectivities.

Habitat fragmentation and large‐scale conservation: what do we know for sure?

We review the ecological effects of habitat fragmentation, comparing the theoretical approaches that have been taken to understanding it with the existing evidence from empirical studies. Theory has

Intraspecific variation in habitat availability among ectothermic animals near their climatic limits and their centres of range

TLDR
The model predicts that an increase of 2–3 °C can result in a large increase in the area of habitat available to these north temperate species, that the length of time that individual patches of successional habitat may be occupied increases and that the distance between habitat patches within the biotope decreases.

Correlated extinctions, colonizations and population fluctuations in a highly connected ringlet butterfly metapopulation

TLDR
Correlated temporal dynamics, variation in habitatquality and the interaction between habitat quality and temporal environmental stochasticity are important determinants of metapopulation persistence and should be incorporated in metapoulation models.

TLDR
It is concluded that the extinction rates of U.K. invertebrates have matched, and probably exceeded, those of vertebrates and vascular plants in the present century.

Butterfly Conservation Management

TLDR
Aspects of butterfly ecology are discussed in relation to sound management of species and faunas, and selected examples from Europe, North America, and elsewhere exemplify increasing global interest in butterfly conservation.

Inbreeding and extinction in a butterfly metapopulation

TLDR
The effect of inbreeding on local extinction in a large metapopulation of the Glanville fritillary butterfly is studied and it is found that extinction risk increased significantly with decreasing heterozygosity, an indication of inmarriage.

TLDR
Within its range, the Lulworth Skipper was almost ubiquitous in areas with tall Brachypodium, and appears both to have increased in numbers and to have spread locally.
