Oceanic Institute Achieves Breakthroughs In Culture Technology For Yellow Tang.

Global Aquaculture Advocate (January February 2013): 82-84.

Summary:

The culture of yellow tang represents a considerable economic opportunity and critical conservation strategy in coral reef ecosystem protection. The Oceanic Institute is working to establish aquaculture techniques to reduce the capture of wild yellow tang. Despite bottlenecks, improvements in broodstock holding systems and dietary regimes are raising egg output and quality. Specialized larval-rearing tanks enable the generation of large numbers of larvae through the critical first-feeding period. Refined lighting and equipment are leading to more consistent feeding.

Extraordinary cranial specialization in a new genus of extinct duck (Aves: Anseriformes) from Kauai, Hawaiian Islands.

Zootaxa 2296: 47–67 (2009)

Abstract:

Talpanas lippa is described as a new genus and species of waterfowl from Kauai, Hawaiian Islands, that is unlike any other known member of the order. It is characterized by a short, stout tarsometatarsus and a braincase that is shallow and wide relative to its length with very small orbits. In comparison with extant species, the optic foramen of Talpanas is remarkably small whereas the maxillo-mandibular foramen, which is the exit point of the trigeminal nerve, is grossly enlarged. Relative to skull length and foramen magnum area, the maxillo-mandibular foramen is one order of magnitude larger in cross-sectional area than that of extant Anseriformes. We conclude that Talpanas had reduced visual abilities, as reflected externally by its small orbits and optic foramen, and a grossly hypertrophied trigeminal foramen. Taken together, this suggests that Talpanas may have been more heavily reliant upon somatosensory (tactile) cues for foraging than any living species of bird. Pectoral elements are unknown, but the evident lack of keen eyesight suggests that the species was flightless, as were many other insular waterfowl.

ERHARDT, A. (2008)

Aus Feuer geboren.

Ornis 6/08:12-16.

Einleitung:

Die einmalige Biodiversität von Hawaii ist enorm fragil – und hoch gefährdet. Trotzdem schwingen auch heute noch Vorstellungen vom Südseeparadies mit, wenn jemand von Hawaii spricht. Wer die Inseln besucht, kann tatsächlich noch immer einen Hauch paradiesischer Faszination erleben. Dafür muss man sich aber die Mühe nehmen, sich etwas abseits von ausgetretenen Pfaden zu bewegen und den weit verbreiteten Massentourismus-Attraktionen auszuweichen.
