RÖDEL, M.-O. & MERSBERG, D.

Vorläufige Liste der Schlangen des Tai-Nationalparks / Elfenbeinküste und angrenzender Gebiete.

SALAMANDRA 36(1): 25-38

Zusammenfassung:

Wir stellen die Schlangenfauna des Tai-Nationalparks (TNP) mit Angabe weiterer biologischer Daten vor. Insgesamt sind nun 39 Schlangenarten aus dem TNP bekannt. Im Primär-Regenwald wurden 22 und in offeneren Habitaten beziehungsweise am Waldrand 17 Schlangenarten gefunden. 15 Arten waren arborikol, 19 lebten am Boden und fünf unterirdisch. Wir gehen davon aus, daß die bisherigen Nachweise etwa zwei Drittel der für diesen letzten großen Regenwald Westafrikas zu erwartenden Arten ausmachen.

MESCHKE, T. (2020)

Klippschliefer- vielfältige Einheitlichkeit oder einheitliche Vielfältigkeit.

ELIOMYS 2/2020: 4-29.

Aus der Zusammenfassung:

Viele Fragen ergeben sich im Hinblick auf das Verbreitungsgebiet des Klippschliefers. Ungeklärt ist die Situation im Südsudan, wo die Unterarten ruficeps, marrensis, butleri, slatini, kerstingi und sharica möglicherweise aufeinander treffen. Klärungsbedarf besteht auch hinsichtlich der Formen habessinica und alpini und ihrer angrenzenden Unterarten wie minor, pallida, butleri und meneliki in Bezug auf die tatsächliche Färbung ihres Rückenflecks und ihre jeweiligen Verbreitungsgrenzen. Außerdem stellt sich die Frage, ob in Süd-Somlia überhaupt Klippschliefer vorkommen. Viele Unterarten und Formen (vor allem aus dem Sudan und Westafrika) sind nur von ganz wenigen Exemplaren bekannt, sodass neues Material aus diesen Regionen einige Fragen beantworten könnte. Die Verbreitungskarten einiger Autoren weisen außerdem keine Verbreitungslücke zwischen Nord-Tansania und Süd-Malawi auf, was ebenfalls weiterer Nachforschungen bedarf. Allerdings ist das Verbreitungsgebiet  wahrscheinlich viel lückenhafter und nicht so kontinuierlich, wie es oft dargestellt wird.

Anhand der btrachteten Felle und von Literaturbeschriebungen stellt der Autor einen eigenen Ansatz zur Systematik der Klippschliefer dar.

The type locality of Pan troglodytes vellerosus (Gray, 1862), and implications for the nomenclature of West African chimpanzees.

Primates. DOI 10.1007/s10329-008-0116-z

Abstract

We  show  that,  in  1862,  Richard  Burton  collected the type specimen of Pan troglodytes vellerosus not on Mount Cameroon, as has been generally assumed, but in Gabon. Therefore, P. t. vellerosus is not the correct name for  the  chimpanzee  population  of  western  Cameroon  and southern  Nigeria,  if  that  population  is  taxonomically  distinct. As First Reviser, we choose the name Pan troglodytes ellioti for   this   population   of   chimpanzees,   based   on Anthropopithecus  ellioti named  by  Matschie  [Matschie , P. (1914)   Neue   Affen   aus   Mittelafrika.  Sitzungsber.  Ges. Naturforsch.  Freunde  Berlin  1914: 323–342]  from  a  specimen in the Humboldt Museum, Berlin, collected in Bascho (=Basho), Cameroon, and given to the museum in 1905.

DIAMOND, J. M. (1987)

Did Komodo dragons evolve to eat pygmy elephants?

Nature 326: 832.

All the large mammal species on which Komodo Dragons now prey were introduced to Flores by humans after BC 3000. What did they eat before then? During the Pleistocene, Flores supported two species of now-extinct elephants, the small Stegodon trigonocephalus florensis and the pygmy S. sompoensis (also called S. timoriensis). Hence Auffenberg's suggestion' that the Dragons evolved as a specialized predator on pygmy elephants, formerly the sole large prey available on Flores.

LAVILLA, E. O. & BRUSQUETTI, F. (2018)

On the identity of Bufo diptychus Cope, 1862 (Anura: Bufonidae).

Zootaxa 4442 (1): 161
ISSN 1175-5326 (Print Edition) & ISSN 1175-5334 (Online Edition)

Abstract:

The enigmatic toad Bufo diptychus was described by Cope (1862) based on a single individual (USNM 5841, now lost) of about 25 mm of SVL, collected during the expedition to La Plata River and tributaries, conducted by Captain Page between 1853 and 1856. As no dwarf species of toad was ever recorded in the surveyed area, and based on some tips that arise from Page’s narrative, we postulate that the description was based on a toadlet. With this hypothesis in mind, we compared Cope’s characterization of B. diptychus with juveniles of all species of Rhinella present in the region, finding an exact match in almost all characters shown by the juveniles of the common “cururú” or “rococo” toad, Rhinella schneideri (Werner 1894). Henceforth, we postulate that R. schneideri is a junior synonym of B. diptychus, under the combination Rhinella diptycha (Cope 1862).

MILLER, C. (2020)

Der Aal - ein geheimnisvoller Wanderer.

FAUNA FOCUS Nr. 61. 12 Seiten.
Hrsg.: WILDTIER SCHWEIZ

Verlagstext:

Der europäische Aal ist ein Fisch der Rekorde: Er ist die am weitesten verbreitete Fischart Europas, gleichzeitig zählt er heute zu den am meisten gefährdeten Fischen. Er legt die weitesten Wanderungen zu seinen Laichgewässern zurück. Und schliesslich zählt er zu den geheimnisvollsten Fischarten.
Der aussergewöhnliche Lebenswandel der Aale macht es überaus schwierig sie zu erforschen: Wanderfische, die ihren Laich im Salzwasser ablegen und ihre Fress- und Wachstumsphase im Süsswasser verbringen, gibt es nur wenige. Die meisten wandernden Fische, wie Lachse und Meerforellen, leben im Salzwasser und laichen im Süsswasser.

Weltweit gibt es rund 20 Aalarten, von welchen die meisten weite Wanderungen zurücklegen. Bis heute ist es jedoch nicht gelungen die genauen Wanderrouten auch nur einer Aalart genau nachzuvollziehen. Sobald sie die Küstengewässer hinter sich lassen und in tiefere Meeresschichten abtauchen verliert sich ihre Spur.

Verlagstext:

At the biological crossroads of the Americas, Costa Rica hosts an astonishing array of plants and animals—over half a million species! Ecotourists, birders, and biologists come from around the world to immerse themselves in the country's unspoiled rain forests, mountains, and beaches, drawn by the likelihood of seeing more than three or four hundred species of birds and other animals during even a short stay. To help all of these visitors and local residents identify and enjoy the wildlife of Costa Rica, this field guide presents nearly three hundred species of birds, mammals, reptiles, amphibians, butterflies, moths, and other invertebrates.

Carrol Henderson, an experienced wildlife biologist, traveler, and tour leader in Costa Rica, has chosen the species that ecotourists are most likely to see, along with a selection of rarer, sought-after animals. He gives a general introduction to each group of animals, followed by individual species accounts that highlight identification features and interesting ecological adaptations for survival. His stunning close-up photographs and distribution maps complete each entry.

In addition, Henderson includes a wealth of data about Costa Rica's natural environment, as well as a trip preparation checklist and lists of conservation organizations, wildlife tourism sites, and wildlife vocalization tapes and CDs. With so much information so readily and readably accessible, this field guide will be essential for planning and enjoying your time in Costa Rica.

DULČIĆ, J. & TUTMAN, P. (2012)

Northernmost record of the shamefaced crab Calappa granulata (Linnaeus, 1767) (Brachyura, Calappidae) in the Mediterranean area.

Crustaceana 85 (4/5):601-606. DOI: 10.2307/23212683.

Introduction:

The box crabs or shamefaced crabs (family Calappidae) are a distinctive group of marine crabs found in tropical and subtropical regions of the world. The family is best known for the shallow water genus Calappa with its unusual, shovel-shaped chelae. The shamefaced crab Calappa granulata is a sublittoral species known from the Mediterranean Sea and adjacent Atlantic Ocean from Portugal to Mauritania, including the Azores, Madeira, the Canary Islands, and the Cape Verde Islands. Spanò et al. (2004) reported that shamefaced crabs are distributed in all oceans, but particularly abundant in tropical waters and inhabiting a wide variety of bottoms (sandy, shell grit, hard rocks, and coral). In the Mediterranean, C. granulata occurs between 10 and 400 m (though not very common), while some authors noted it lives on sandy mud and muddy detritus at depths between 13 and 400-700 m. Typically, it burrows in inshore soft bottoms. The species can reach 10 cm CL (carapace length) and 9.2 cm CW (carapace width). In recent years, it has been found in the Mediterranean Sea at several locations: in the Gulf of Taranto (Ionian Sea) , in the Strait of Sicily , in the coastal waters of the Sea of Marmara, and in Edremit Bay (Aegean Sea). In the Adriatic Sea, it is very rare and has only been found in areas of the Southern and Middle Adriatic. The last records of this species were from the Southern Adriatic, during trawling operations in the framework of the E.U. Project MEDITS.
