其實今天要說一下那隻雙星紫蘿蘭貓, 我看到那條魚的時候, 本來以為是下眼鱨科(Horabagridae)的Horabagrus brachysoma或H. nigricollaris(黃金貓, 金紅尾鯰, 一點貓, 中名是混用的), 查了一下才發現應該是鱨科(Bagridae)的 Mystus bimaculatus. 我不確定這條魚以往是否有中文俗名, 若有大大知道請不吝告知. Mystus這個屬中還有M. pulcher與M. rufescens兩個種具有兩個大斑點, 但與bimaculatus的體型相去甚遠, 應該不會有鑑識上的混淆才是.

那隻窈窕虎鯨(喔好威的名字)是那種白天睡覺晚上出來亂晃吃小魚或紅蟲的魚, 如果養過帝王虎鯨, 就知道這類的魚最好還是和夜行性的中小型底棲鯰魚一起養, 以免在白天遭受騷擾, 晚上又吃不到東西.

另一個議題是"茱莉豹鼠是什麼?" [待續]

野生地鼠陸龜因草酸引發腎衰竭致死案例

文獻來源: Jacobson ER, Berry KH, Stacy B, Huzella LM, Kalasinsky VF, Fleetwood ML, Mense MG. 2009. Oxalosis in wild desert tortoises, Gopherus agassizii. Journal of Wildlife Diseases 45(4): 982-988.

Abstract
We necropsied a moribund, wild adult male desert tortoise (Gopherus agassizii) with clinical signs of respiratory disease and elevated plasma biochemical analytes indicative of renal disease (blood urea nitrogen [415 mg/dl], uric acid [11.8 mg/dl], sodium [>180 mmol/l] and chloride [139 mmol/l]). Moderate numbers of birefringent oxalate crystals, based on infrared and electron microscopy, were present within renal tubules; small numbers were seen in colloid within thyroid follicles. A retrospective analysis of 66 additional cases of wild desert tortoises was conducted to determine whether similar crystals were present in thyroid and kidney. The tortoises, from the Mojave and Sonoran deserts, were necropsied between 1992 and 2003 and included juveniles and adults. Tortoises were classified as healthy (those that died due to trauma and where no disease was identified after necropsy and evaluation by standard laboratory tests used for other tortoises) or not healthy (having one or more diseases or lesions). For all 67 necropsied tortoises, small numbers of crystals of similar appearance were present in thyroid glands from 44 of 54 cases (81%) and in kidneys from three of 65 cases (5%). Presence of oxalates did not differ significantly between healthy and unhealthy tortoises, between age classes, or between desert region, and their presence was considered an incidental finding. Small numbers of oxalate crystals seen within the kidney of two additional tortoises also were considered an incidental finding. Although the source of the calcium oxalate could not be determined, desert tortoises are herbivores, and a plant origin seems most likely. Studies are needed to evaluate the oxalate content of plants consumed by desert tortoises, and particularly those in the area where the tortoise in renal failure was found.

Corydoras evelynae實在是很妙的魚. 它的模式產地在巴西, 但是哥倫比亞及秘魯都能出口, 所以倒底是這條魚(或這群魚)分布廣泛? 還是各地的煙圈鼠的各型都是當地鼠魚經由先然雜交產生的產物? 至於那些長得很像naoki的魚可參考先前2009-10-05的討論. 這次進口的"naoki"與2008年進口的那批魚是有一點點不太一樣. 這次進口的魚在胸部出現了類似acutus的細點, 而不是過去那批naoki的粗斑點. 但是已知的相似物種分布在秘魯境內的除了naoki還有所謂的"Corydoras sp. Mususu longnose"和"Corydoras sp. Sazan Kuros super"(コリドラス スーパーサザンクロス), 所以情況倒底是怎樣, 我不太清楚耶. naoki是一條與C91與斑鰭鼠共棲的魚, 但C91在近年已經被好事的日本人分成好幾個型, 這些型是否暗示著任何地理分化我還不清楚, 但如果這次進口的naoki真的是秘魯來的, 有沒有一個可能, 就是naoki (=C92)與C91在不同的河段的斑紋具有趨同的現象呢? 然後這樣的分化就形成了所謂naoki, Mususu longnose或Sazan Kuros呢? 這次進口的魚, 讓我東想西想後, 我會傾向於先把它當成Corydoras Mususu longnose, 因為它仍然缺乏一般naoki所具備的三個特徵: (1) 吻部與鰓蓋的黑斑; (2) 側線黑線到尾柄部加粗; (3) 胸部黑斑集中, 並非細點分散. 以下是幾個網頁所具有的"naoki"影象:
註一: naoki不是一個正式學名, 只是一個商用名
註二: 那個Sazan Kuros搞半天是"Southern Cross"的日文發音, 意指"南十字星", 但有人認為Mususu LN與Southern Cross是一樣的魚

隱孢子蟲症(Cryptosporidiosis)導致四趾陸龜與餅乾龜死亡的案例

文獻來源: Griffin C, Reavill DR, Stacy BA, Childress AL, Wellehan Jr JFX. 2010. Cryptosporidiosis Caused By Two Distinct Species In Russian Tortoises And A Pancake Tortoise, Veterinary Parasitology, In Press

Abstract
Cryptosporidiosis in squamates is well documented, but there is very limited information available on cryptosporidiosis in testudines. We describe three cases of cryptosporidiosis in tortoises with associated pathology. Two Russian tortoises (Agrionemys [Testudo] horsfieldii) and a pancake tortoise (Malacochersus tornieri), all from separate collections, were found dead. At necropsy, two had histological evidence of intestinal cryptosporidiosis and one had gastric cryptosporidiosis. Consensus Cryptosporidium sp. PCR and sequencing was used to identify the Cryptosporidium sp. present in these three tortoises. In the juvenile Russian tortoise with gastric cryptosporidiosis, the organism had 98% homology with a previously reported sequence from an Indian star tortoise isolate. A second chelonian Cryptosporidium sp. was identified in the pancake tortoise and the second Russian tortoise. This sequence was 100% identical to a shorter gene sequence previously reported in a marginated tortoise. This is the first report coordinating pathology with Cryptosporidium characterization in chelonians. The two Cryptosporidium sp. found in tortoises segregate according to site of infection, and there may be further differences in pathology, host range, and transmission. These Cryptosporidium sp. appear to be able to infect diverse tortoise host species. This may be an under-recognized problem in tortoises.

Abstract

We discuss the morphology of the respiratory system regarding the phylogenetic relation among selected Testudines (Tetrapoda: Amniota). Lung structure and the associated coelomic organization are compared in Platysternon megacephalum and in representatives of the most-likely closely related taxa Chelydridae and Testudinoidea (Emydidae + Testudinidae). P. megacephalum shows horizontal intrapulmonary septation in the medial chambers, dividing them into dorsal and ventral lobes. This structure is found only in Platysternon and in the Emydidae, and is interpreted as a possible synapomorphy for these two taxa. In addition to further suggested synapomorphies for Platysternon and the Testudinoidea, we found - in contrast to previous reports - a small post-pulmonary septum (PPS) and incomplete coelomic compartmentalization in the Chelydridae. Thus, all major taxa of Testudines possess a PPS. Since this structure is also present in mammals, archosaurs and some lepidosaurs, the plesiomorphy of a coelomic compartmentalization by the PPS in amniotes in general should be considered. These preliminary results indicate that further comparative study of the respiratory apparatus might help resolve the phylogenetic relationships among the Testudines, as well as to shed light on its evolution among the Amniota.

僅使用mtDNA序列資訊將誤導澤龜科親緣關係的重建以及數個瀕危物種之保育地位

[superlink: Wiley Intersceicne]

文獻來源: Wiens JJ, Kuczynski CA, Stephens PR. 2010. Discordant mitochondrial and nuclear gene phylogenies in emydid turtles: implications for speciation and conservation. Biological Journal of the Linnean Society 99(2): 445-461.

Abstract
Do phylogenies and branch lengths based on mitochondrial DNA (mtDNA) provide a reasonable approximation to those based on multiple nuclear loci? In the present study, we show widespread discordance between phylogenies based on mtDNA (two genes) and nuclear DNA (nucDNA; six loci) in a phylogenetic analysis of the turtle family Emydidae. We also find an unusual type of discordance involving the unexpected homogeneity of mtDNA sequences across species within genera. Of the 36 clades in the combined nucDNA phylogeny, 24 are contradicted by the mtDNA phylogeny, and six are strongly contested by each data set. Two genera (Graptemys, Pseudemys) show remarkably low mtDNA divergence among species, whereas the combined nuclear data show deep divergences and (for Pseudemys) strongly supported clades. These latter results suggest that the mitochondrial data alone are highly misleading about the rate of speciation in these genera and also about the species status of endangered Graptemys and Pseudemys species. In addition, despite a strongly supported phylogeny from the combined nuclear genes, we find extensive discordance between this tree and individual nuclear gene trees. Overall, the results obtained illustrate the potential dangers of making inferences about phylogeny, speciation, divergence times, and conservation from mtDNA data alone (or even from single nuclear genes), and suggest the benefits of using large numbers of unlinked nuclear loci.

於香港機場查獲的六種走私龜中所檢出十種內寄生蠕蟲

文獻來源: Murray RA. 2004. Endohelminths from six rare species of turtles (Bataguridae) from southeast Asia confiscated by international authorities in Hongkong, China. Master's thesis, Taxas A & M University.

Abstract

Specimens of 6 species of threatened, vulnerable, and endangered turtles (Cuora amboinensis, Cyclemys dentata, Heosemys grandis, Orlitia borneensis, Pyxidea mouhotii, and Siebenrockiella crassicollis) belonging to family Bataguridae, were confiscated in Hong Kong, China on 11 December 2001 by international authorities. Endohelminth studies on these turtle species are scarce, and this study provided a rare opportunity to examine a limited number of specimens for endohelminths. Ten different parasite species were collected and there were 16 new host records. This is the first record of a parasite from P. mouhotii. The parasite prevalences found in this study provide a basis for a better understanding of the phylogenetic relationships of the family Bataguridae to other families, especially Testudinidae. Based on known life cycles, parasites found provided an indication of food preferences of these 6 turtle species that support previous studies of the turtles’ feeding habits. However, the results of the parasite survey from O. borneensis provided additional feeding habit information. The list of endohelminths herein is intended to provide a foundation for future parasite studies of the 6 species of Asian turtles.
