Mylabris (Mylabris) snizeki sp. nov. from Jordan is described and an identification key to Jordanian species of the nominotypical subgenus provided.

Metapopulation models typically assume that suitable habitats occupied by local populations and unsuitable matrix separating them form a 'black-and-white' landscape mosaic, in which dispersal is primarily determined the spatial configuration of habitat patches. In reality, however, composition also likely to influence dispersal. Using intensive mark-recapture surveys we investigated inter-patch movements Maculinea (Phengaris) nausithous M. teleius occurring sympatrically six metapopulations....

A positive effect of (meta)population density on emigration has been predicted by many theoretical models and confirmed empirically in various organisms. However, butterflies, the most popular species for dispersal studies, evidence its existence so far equivocal, with negative relationships between being reported more frequently. We analysed sympatric metapopulations two Maculinea intensively surveyed mark-release-recapture methods 7 years. Dispersal parameters, derived using virtual...

Butterflies of the genus Phengaris have a highly specialised life cycle involving an obligatory relationship with Myrmica ants.A knowledge host ant specificity is essential for understanding between particular species and its hosts also important conservation these butterflies.Data on were collected in Poland, Czech Republic, Slovakia Ukraine.Five different used by P. teleius as (M.scabrinodis, M. rubra, ruginodis, rugulosa gallienii) at most localities it was not possible to distinguish...

Abstract In most metapopulation models dispersal is assumed to be a fixed species‐specific trait, but in reality abilities are highly sensitive various selective pressures. Strict isolation of metapopulation, which precludes any influx immigrants (and their genes) from outside and makes it impossible for emigrants reach other localities with suitable habitat, thus reducing fitness benefits long‐distance zero, may expected impose strong selection against dispersal. We tested the above...

Abstract In recent years, the keeping of ornamental freshwater animals and plants in garden ponds has been growing popularity. Water hyacinth ( Eichhornia crassipes ) is one preferred macrophytes seasonally imported mainly from South-eastern Asia throughout world. This constitutes a secondary introduction inasmuch as species native to South America. Although many assemblages aquatic invertebrates have described associated with this plant wild, there no research focused on their potential via...

Many European butterfly species are currently experiencing serious declines, and may be threatened with extinction. Nevertheless, due to limited knowledge on the biology ecology, detailed assessments of endangerment level not possible, instead identifying conservation concern has rely proxies. Earlier studies suggested several characteristics, including host plant specificity, overwintering stage, patch size requirements or mobility, as potentially useful indicators vulnerability, but...

The aardvark is popular in many zoological gardens the European Union. These creatures are nocturnal, and aardvarks wild known to walk distances of 4 km 7 per night. Despite what about their biology, most kept indoor enclosures with little space for movement. This lack leads a tendency toward obesity compromised welfare. With wide distribution Sub-Saharan Africa, perceived as thermophilic nonhuman animals. Nevertheless, some records suggest they may be able adapt colder climates can active...

Abstract Background Metapopulation persistence in fragmented landscapes is assured by dispersal of individuals between local populations. In this scenario the landscape topography, although usually neglected, may have an important role shaping throughout matrix separating habitat patches. Due to inter-sexual differences optimal reproductive strategies, i.e., males maximizing number mating opportunities and females offspring survival chances, topography-related constraints are expected exert...

The Odlezelské jezero National Nature Monument was established to protect Lake Odlezy, the youngest natural lake in Czech Republic, situated near Odlezly western Bohemia. This created 1872 by a landslide that blocked stream. aquatic molluscs of this unique site were studied 2013 and 2023. Altogether, 16 species (8 gastropods 8 bivalves) found at 13 sites. Molluscan communities streams, springs small wetlands surrounding are very poor, consisting 1–4 species. In contrast, lake. Particularly...

Interspecies mating is rarely observed even in the wild. Such a case Lycaenidae reported and photographically documented for species pairing Phengaris teleius (Bergsträsser, 1779) P. nausithous 1779), which was on 19 July 2016 northern Bohemia near village of Hynčice, Czech Republic. Possible causes this phenomenon are discussed.

A highly isolated and the last autochthonous Czech Republic population of endangered Euphydryas maturna (Lepidoptera: Nymphalidae) is monitored since 2001 by larval nests counts. The 20 years` time series displays remarkable abundance fluctuations with peak-to-peak period 11 years, peak numbers &amp;gt;150 bust &amp;lt;15 (arithmetic harmonic means: 92.6 36.3). Establishment more favourable management site probably heightened prolonged boom phase but did not alter overall pattern. We...

ABSTRACT Aim The distribution of within-species lineages has been affected by Quaternary climate changes, and population differentiation influenced species life histories. We investigated whether the individual mitochondrial genetic reflects constituent species’ traits. Using functionally diverse group butterflies, we examined which are present in Central Europe, an important suture zone. Location Czech Republic Western Palearctic. Taxon A total 140 butterfly species. Methods sequenced DNA...

Abstract In recent decades, changes in meadows maintenance have reduced the populations of endangered butterfly species Phengaris nausithous (Bergsträsser, 1779) and P. teleius 1779). Currently, are either abandoned or intensively used. Unfortunately, both these managements considered unfavourable for grassland species. this study, effect suitable meadow management on population sizes above mentioned was investigated. The experiment performed at locality Dolní Labe (Děčín, Czech Republic)....
