Threatened fishes of the world: <Emphasis Type="Italic">Chirostoma aculeatum</Emphasis> Barbour, 1973 (Atherinopsidae)

Chirostoma aculeatum is a rare silverside found only in central Mexico. Its conservation status is considered in addition to providing information regarding its ecology, life history, and distribution.     

A new name in <Emphasis Type="Italic">Pavetta</Emphasis> L. (<Emphasis Type="Italic">Rubiaceae</Emphasis>)

Summary  The name Pavetta modesta (Hiern) S. E. Dawson is a later homonym of P. modesta Bremek. Pavetta crystalensis is proposed as a new name.     

Threatened fishes of the world: <Emphasis Type="Italic">Notropis boucardi</Emphasis> (Günther 1868) (Cyprinidae)

Synopsis We present a short communication on an endangered freshwater fish species from central Mexico, Notropis boucardi, to be published in the threatened fishes of the world series.     

Typification of <Emphasis Type="Italic">Metrosideros regelii</Emphasis> (<Emphasis Type="Italic">Myrtaceae</Emphasis>) and consideration of its generic position

Summary  The type specimen of Metrosideros regelii is discussed. It contains a mixture of two species, representing different genera, and a lectotype is chosen. The generic position of the species is considered in the light of morphology and recent molecular evidence and the new combination, Mearnsia regelii, made.     

Threatened fishes of the world: <Emphasis Type="Italic">Chondrostoma meandrense</Emphasis> Elvira, 1987 (Cyprinidae)

Chondrostoma meandrense is an endangered freshwater fish species in Anatolia (Turkey). Its population has declined and should be strictly protected.     

The Invasive <Emphasis Type="Italic">Buddleja davidii</Emphasis> (Butterfly Bush)

Buddleja davidii Franchet (Synonym. Buddleia davidii; common name butterfly bush) is a perennial, semi-deciduous, multi-stemmed shrub that is resident in gardens and disturbed areas. Since its introduction to the United Kingdom from China in the late 1800s, B. davidii has become an important component in horticulture and human culture. Despite its popularity as a landscape plant, B. davidii is considered problematic because of its ability to naturalize outside of gardens and rapidly invade and dominate disturbed natural areas across a wide range of physical conditions. The primary goal of this paper is to synthesize what is known about B. davidii in order to understand the impacts caused by the continued presence of B. davidii in gardens and natural landscapes. We also address management of B. davidii and discuss the repercussions of management strategies and policies currently implemented to protect or remove B. davidii from natural ecosystems.

Zusammenfassung   Buddleja davidii Franchet (Synonym Buddleia davidii, umgangsprachlich “Schmetterlingsflieder”) ist ein ausdauernder, halb-immergruener, mehrstaemmiger Busch welcher in Gaerten und auf Umbruchflaechen gedeiht. Seit seiner Einfuehrung in die UK aus China im spaeten 19. Jahrhundert hat B. davidii in Pflanzenzucht und Kultivierung stark an Bedeutung gewonnen. Unabhaengig von seiner Beliebtheit in der Landschaftsgestaltung stellt B. davidii wegen seiner Faehigkeit, sich ueber Gartengrenzen hinaus unter einer Vielzahl von Wachstumsbedingungen in gestoerten Naturgebieten schnell auszubreiten und dort die einheimische Flora zu dominieren, ein grosses Problem dar. Das Ziel der vorliegenden Rezension ist es eine Synopsis zu erstellen, welche die Auswirkungen und Gefahren der konstanten Praesenz von B. davidii in Gaerten und der Naturlandschaft verdeutlicht. Management Optionen und -Fehlschlaege sowie aktuelle Regulationen zu dem Zwecke B. davidii aus natuerlichen Ecosystemen zu entfernen oder sein vordringen zu verhindern, werden ebenfalls diskutiert.
