Dispersal in a metapopulation of the critically endangered Danube Clouded Yellow butterfly Colias myrmidone: implications for conservation

Colias myrmidone has suffered a dramatic decline in Europe, and now its occurrence is restricted to just a few countries. We investigated one of the last viable metapopulations (Knyszyn Forest, NE Poland), where the butterfly is almost completely dependent on forestry, inhabiting some clearings and young tree plantations rich in larval food plants (Chamaecytisus ruthenicus) and...

Comparison of three trap types in sampling saproxylic beetles living in hollow urban trees

Hollow trees are an important habitat for a large number of saproxylic invertebrates, many of which are rare or threatened. Large old trees occur frequently in cities, but the saproxylic fauna inhabiting these trees has been poorly studied. Sampling in urban areas includes the risk of trap failure due to human interference, which needs to be considered when designing sampling...

Microhabitat selection by ovipositing females and pre-diapause larvae of a Welsh population of Euphydryas aurinia (Lepidoptera: Nymphalidae)

Habitat requirements of the marsh fritillary Euphydryas aurinia have been studied intensively in recent years in order to inform conservation action on this rapidly declining species. Autecological studies have been undertaken on various spatial scales to account for differences in mobility between life stages. It has become clear that resource utilisation by the species varies...

Demographics and spatial ecology in a population of cryptic wood white butterfly Leptidea juvernica in Northern Ireland

The cryptic wood white Leptidea juvernica is one of a newly-discovered species complex comprising three morphologically similar species in Europe. In the British Isles, L. juvernica is absent from Great Britain, but is widespread in Ireland, where it has experienced recent declines; it is classed as a priority species in Northern Ireland. Using a mark–recapture approach, this...

Determining the long-term habitat preferences of the Duke of Burgundy butterfly, Hamearis lucina, on a chalk grassland reserve in the UK

The Duke of Burgundy butterfly has undergone considerable range contractions across Europe and since the 1970s has lost around 84% of its former distribution in the UK. Despite its endangered status, the butterfly is understudied, with few papers directly investigating its habitat requirements. This limited research effort focusses on the larval life stage, with relatively little...

Fly family diversity shows evidence of livestock grazing pressure in Mongolia (Insecta: Diptera)

Members of the insect order Diptera respond differentially to environmental changes and may play an important role in understanding the effects that livestock grazing disturbances have on biodiversity. Here we examine how increasing grazing pressures on the Mongolian steppe affect Diptera diversity and abundance. Using 2334 yellow pan traps, we sampled a total of 132 sites over...

Occupancy modeling of Parnassius clodius butterfly populations in Grand Teton National Park, Wyoming

Estimating occupancy patterns and identifying vegetation characteristics that influence the presence of butterfly species are essential approaches needed for determining how habitat changes may affect butterfly populations in the future. The montane butterfly species, Parnassius clodius, was investigated to identify patterns of occupancy relating to habitat variables in Grand...

Potential range of impact of an ecological trap network: the case of timber stacks and the Rosalia longicorn

Although the negative impact of timber stacks on populations of saproxylic beetles is a well-known phenomenon, there is relatively little data concerning the scale of this impact and its spatial aspect. Beech timber stored in the vicinity of the forest can act as an ecological trap for the Rosalia longicorn (Rosalia alpina), so in this study we have attempted to determine the...

Use of a genetically informed population viability analysis to evaluate management options for Polish populations of endangered beetle Cerambyx cerdo L. (1758) (Coleoptera, Cerambycidae)

A paucity of genetic information and the drastic decline in population size of the beetle Cerambyx cerdo has made this species a high priority for research and conservation management. The state-listed beetle, a saproxylic insect associated with oaks, has a discontinuous range, with larger and more connected populations in southern Europe and small and isolated populations in the...

Oviposition site selection of a threatened moth Eriogaster catax (Lepidoptera: Lasiocampidae) in agricultural landscape—implications for its conservation

Shrubby field margins and hedgerows play an important role for many species of flora and fauna in agro-ecosystems, including those which are rare or endangered. A characteristic species of these semi-natural habitats in agricultural landscape is the Eastern eggar, Eriogaster catax (Linnaeus, 1758): a moth species threatened in many European countries. In this study we...

Environmental noise reduces predation rate in an aquatic invertebrate

Noise is one of a wide range of disturbances associated with human activities that have been shown to have detrimental impacts on a wide range of species, from montane regions to the deep marine environment. Noise may also have community-level impacts via predator–prey interactions, thus jeopardising the stability of trophic networks. However, the impact of noise on freshwater...

How to preserve a butterfly species within an urbanising settlement and its surroundings: a study of the scarce copper (Lycaena virgaureae L.) in southern Sweden

Urbanisation is a rapidly ongoing process worldwide with profound consequences for wildlife in urban and peri-urban areas. Species are affected by habitat loss, habitat alternation and degradation, fragmentation and increased human population and activity. Habitat loss can occur due to construction of housing and infrastructure in peri-urban areas and within urban areas due to...

Sampling bees in tropical forests and agroecosystems: a review

Bees are the predominant pollinating taxa, providing a critical ecosystem service upon which many angiosperms rely for successful reproduction. Available data suggests that bee populations worldwide are declining, but scarce data in tropical regions precludes assessing their status and distribution, impact on ecological services, and response to management actions. Herein, we...

Adult demography of an isolated population of the threatened butterfly Scarce Heath Coenonympha hero and its conservation implications

Scarce Heath Coenonympha hero is considered to be one of the most seriously threatened European butterflies, especially declining in western and central Europe. It usually occurs in small, discrete colonies forming metapopulation systems, but the exchange of individuals between habitat patches is considered limited. Therefore the persistence of the species in fragmented systems...

Simplified and still meaningful: assessing butterfly habitat quality in grasslands with data collected by pupils

Public participation in scientific research, now commonly referred to as citizen science, is increasingly promoted as a possibility to overcome the large-scale data limitations related to biodiversity and conservation research. Furthermore, public data-collection projects can stimulate public engagement and provide transformative learning situations. However, biodiversity...

Butterfly diversity and seasonality of Ta Phin mountain area (N. Vietnam, Lao Cai province)

Human pressures on the environment are changing spatially and temporally, with profound implications for the planet’s biodiversity. Butterflies are important indicators for environmental change and are a suitable group to detect areas of high conservation concern and prioritize conservation efforts. To obtain data to support urgently-needed conservation measures, we surveyed the...

Long-term monitoring of Phengaris (Lepidoptera: Lycaenidae) butterflies in the Přelouč surroundings (Czech Republic): is the waterway construction a serious threat?

The monitoring of sympatrically occurring Phengaris teleius and P. nausithous metapopulations in the surroundings of Přelouč, Czech Republic, was launched over a decade ago in connection with the planned waterway construction on the Elbe river. The mark-recapture surveys were initially restricted to 10 habitat patches on the right river bank, but in 2010 three new patches were...

Could the vulnerable great Capricorn beetle benefit from the introduction of the non-native red oak?

Introduced plants are often identified as the major conservation concern worldwide, however, they also may offer conservation benefits, among others, provide habitat and/or food resources to protected animals. Here we aimed to assess the ability of the great Capricorn beetle Cerambyx cerdo, a highly specialised species associated with mature oaks, to use non-native red oak...
