The Isophya species of Central and Western Europe (Orthoptera: Tettigonioidea: Phaneropteridae)
rope (Heller et al. 1998). In this region, it is second with regard to species richness after the closely related genus Poecilimon, but first with regard to the difficulties to identify the species.Expand
A comparative ZOO-FISH analysis in bats elucidates the phylogenetic relationships between Megachiroptera and five microchiropteran families
Fluorescence in-situ hybridization with human whole chromosome painting probes (WCPs) was applied to compare the karyotypes of members of five bat families. Twenty-five evolutionarily conserved unitsExpand
Karyotype comparison and phylogenetic relationships of Pipistrellus-like bats (Vespertilionidae; Chiroptera; Mammalia)
Detailed karyotype descriptions of 20 Pipistrellus-like bat species belonging to the family Vespertilionidae are presented. For the first time, chromosomal complements of four species, i.e.Expand
Resource partitioning of sonar frequency bands in rhinolophoid bats
SummaryIn the Constant Frequency portions of the orientation calls of various Rhinolophus and Hipposideros species, the frequency with the strongest amplitude was studied comparatively. (1) In theExpand
A new biophysical method to determine the gain of the acoustic trachea in bushcrickets
A method is described for measuring the gain (i.e., the change of amplitude and phase angle) for sounds that propagate to the internal surface of the tympana in ears working as pressure differenceExpand
Cryptic mammalian species: a new species of whiskered bat (Myotis alcathoe n. sp.) in Europe
Abstract. The analysis of morphological, behavioural and genetic characters of whiskered bats revealed a new European bat species within the family Vespertilionidae. We describe the morphology,Expand
The chemical composition of the spermatophore in some species of phaneropterid bushcrickets (Orthoptera: Tettigonioidea).
Male bushcrickets transfer large spermatophores of up to 40% of male body mass to the females during mating. These large nuptial gifts are later consumed by the female and have been shown to affectExpand
Acoustic signalling in palaeotropical bushcrickets (Orthoptera: Tettigonioidea: Pseudophyllidae): does predation pressure by eavesdropping enemies differ in the Palaeo‐ and Neotropics?
When producing its calling song, a male bushcricket exposes itself to predators which use this sound for localization. Male signalling therefore has to be a compromise between attracting females andExpand
New Species in the Old World: Europe as a Frontier in Biodiversity Exploration, a Test Bed for 21st Century Taxonomy
The number of described species on the planet is about 1.9 million, with ca. 17,000 new species described annually, mostly from the tropics. However, taxonomy is usually described as a science inExpand
The evolution of sex differences in mate searching when females benefit: new theory and a comparative test
Sexual selection is thought to have led to searching as a profitable, but risky way of males obtaining mates. While there is great variation in which sex searches, previous theory has not consideredExpand
