A comparative ZOO-FISH analysis in bats elucidates the phylogenetic relationships between Megachiroptera and five microchiropteran families
Comparison of neighboring segment combinations found in Chiroptera with those found in other mammalian taxa revealed six synapomorphic features for Chiropteran species, and monophyly of Chiropters is strongly supported.
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 the…
The Isophya species of Central and Western Europe (Orthoptera: Tettigonioidea: Phaneropteridae)
The identification of Isophya species was based mainly on subtle differences in the shape of cerci, pronotum, tegmina and ovipositor, which is not surprising, that even in Western and Central Europe nearly half of the currently recognised species have not been described before the beginning of the secondhalf of the last century.
Karyotype comparison and phylogenetic relationships of Pipistrellus-like bats (Vespertilionidae; Chiroptera; Mammalia)

According to the results, the species Pipistrellus (Neoromicia) capensis belongs to the Vespertilionini and not to the Pipistrelini, and it is proposed to elevate the subgenus NeoromicIA to generic rank.
New Species in the Old World: Europe as a Frontier in Biodiversity Exploration, a Test Bed for 21st Century Taxonomy
It is shown that contrary to general belief, developed and heavily-studied parts of the world are important reservoirs of unknown species, and the importance of developing a system that better supports and guides this formidable workforce as they seek to overcome the Taxonomic Impediment and speed up the process of describing the planetary biodiversity before it is too late.
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,…

A method is described for measuring the gain for sounds that propagate to the internal surface of the tympana in ears working as pressure difference receivers, and other methods, which in the past have been used for estimating the gain of sound pathways inside animal bodies are compared.
Acoustic signalling in palaeotropical bushcrickets (Orthoptera: Tettigonioidea: Pseudophyllidae): does predation pressure by eavesdropping enemies differ in the Palaeo‐ and Neotropics?

- 1 November 1995
None of the various types of bat avoidance behaviour observed in the neotropical Pseudophyllidae was found in the Malaysian species, and the possibility of different predation pressures in the Palaeo- and Neotropics is discussed.
