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.

國際爬蟲貿易是造成波蘭境內發現外來蜱類的原因

Abstract
The problem of the unnatural transfer of exotic ticks (Acari: Ixodida) on reptiles (Reptilia) imported to Poland is presented. In the period from 2003 to 2007, 382 specimens of reptiles belonging to the following genera were investigated: Testudo, Iguana, Varanus, Gongylophis, Python, Spalerosophis, Psammophis. The reptiles most infested with ticks are imported to Poland from Ghana in Africa, and are the commonly bred terrarium reptiles: Varanus exanthematicus and Python regius. As a result of the investigations, the transfer of exotic ticks on reptiles to Poland was confirmed. There were 2104 specimens of the genera Amblyomma and Hyalomma. The following species were found: Amblyomma exornatum Koch, 1844, Amblyomma flavomaculatum (Lucas, 1846), Amblyomma latum Koch, 1844, Amblyomma nuttalli Donitz, 1909, Amblyomma quadricavum (Schulze, 1941), Amblyomma transversale (Lucas, 1844), Amblyomma varanense (Supino, 1897), Amblyomma sp. Koch, 1844, Hyalomma aegyptium (Linnaeus, 1758). All the species of ticks of genus Amblyomma revealed have been discovered in Poland for the first time. During the research, 13 cases of anomalies of morphological structure were confirmed in the ticks A. flavomaculatum, A. latum and H. aegyptium. The expanding phenomenon of the import of exotic reptiles in Poland and Central Europe is important for parasitological and epidemiological considerations, and therefore requires monitoring and wide-ranging prophylactic activities to prevent the inflow of exotic parasites to Poland.

蛤? 食人魚的學名是"S. rhombeus"?

以下轉載自農委會的農政與農情
農委會為維護人畜安全及生態環境,於民國 89 年 2 月依法公告禁止飼養、輸入或輸出三類動物,包括美洲巨水鼠科(學名:Myocastoridae)、食人魚(學名:Serrasalmus rhombeus)及電鰻科(學名:Electrophoridae)。去年桃園縣發生美洲巨水鼠一批遭民眾野放事件,經桃園縣家畜疾病防治所捕獲,其中 13 隻人道處理, 6 隻絕育後由該縣海洋生物教育館代為留置,供生態教育宣導用。

所謂的"食人魚"意指一個單一物種? 還是一群物種? 當時給這個建議的學者真的知道整個Serrasalmidae裏面倒底有那個屬才是肉食性種類? PygocentrusSerrasalmus要怎麼分? 然後真的知道倒底那一個PygocentrusSerrasalmus物種在南美洲有"無故攻擊"事件嗎? 還是說, 隨便丟一個S. rhombeus這個物種的學名, 湊上一個"食人魚"的名字, 一切完全只是根據道聽塗說的刻板印象呢? 我很同意有很多的生物不應該成為寵物, 而且以台灣人對寵物的態度, 不管什麼樣的生物都可能被遺棄, 但是若大學教授不懂裝懂, 給主管單位指指點點, 長期造成業者與民眾的困擾, 而且造成許多NGO團體複製這些錯誤資訊以訛傳訛, 這樣對於外來種的防治真的是好事嗎? 隨便指稱一個市面上不太常見的物種會咬人, 與藉由公權力鼓勵放任外來大型食用魚的放流, 請問何者對台灣環境的衝擊較大?

水族館遭檢舉販賣食人魚
Practicafishkeeping對食人魚遭電影扭曲形象的看法
JH Mol在2006年對蘇利南的數則偶發性攻擊事件的看法, 他強調許多的所謂食人魚攻擊根本缺乏記載, 而且被攻擊的狀況通常都是因為水域狹小, 人類干擾(小孩跑進食人魚繁殖的池塘玩水)所造成的

如果大型犬隻攻擊鄰居路人的案例那麼多, 為何不禁養大型犬? 更何況狗也是外來種. 所以說科學家的意見與政策常常也不具邏輯性, 憑藉的都是自我感覺良好?

印尼摩鹿加群島產裂足虎Gehyra barea的系統分類地位與新幾內亞西岸Raja Ampat島新種之描述

文獻來源: Oliver P, Sistrom M, Tjaturadi B, Krey K, Richards S. 2010. On the status and relationships of the gecko species Gehyra barea Kopstein 1926, with description of new specimens and a range extension. Zootaxa 2354: 45-55.

Abstract
Gehyra barea is a poorly known gecko species from the southern Banda Islands, Maluku Province, Indonesia, that has received scant attention since it was described in 1926. A combination of morphological characters distinguish the types of this species from all other described Gehyra, and suggest that it is a distinct taxon. These same morphological characters occur in two recently collected specimens from the Raja Ampat Islands, just off the west coast of New Guinea, that we assign to this species, extending the known range of the taxon by over six hundred kilometres. We provide a revised and extended diagnosis and description of the species based on these new specimens. Morphological and genetic data from these specimens indicate G. barea is closely related to Gehyra baliola from further east in southern New Guinea, and that these species form a clade with Geyhra oceanica. Gehyra is a taxonomically challenging group, and the status of most species from the Melanesian region is in need of review.

Abstract
Based on differences in coloration, morphometrics, and scalation, I recognize seven species of anoles related to Anolis pentaprion in Central America: Anolis beckeri (southeastern Mexico to northern Nicaragua), A. cristifer (Pacific lowlands of Chiapas to central Guatemala), A. fungosus (Caribbean premontane zone from central Costa Rica to western Panama), A. pentaprion (Caribbean lowlands of southern Nicaragua to northwestern Colombia, also on Pacific versant in central and eastern Panama), A. salvini (Pacific premontane and lower montane zones from central Costa Rica to western Panama), A. utilensis (restricted to Isla de Utila, Honduras), and a new species (from the Pacific lowlands of Costa Rica and western Panama) described herein. The new species differs from A. pentaprion by having a red male dewlap with few large, widely spaced gorgetal scales scattered across the dewlap (pink with purple pigment between rows of gorgetals, and with regular rows of numerous small, narrowly spaced gorgetal scales in A. pentaprion). Furthermore, I resurrect the name A. beckeri Boulenger for the pentaprion-like populations of anoles distributed from southeastern Mexico to northern Nicaragua. Anolis beckeri differs from A. pentaprion most obviously in the dorsal tail scalation (a serrated caudal crest present in A. pentaprion versus no such crest in A. beckeri) and dewlap scalation (gorgetal rows with 17–25 narrowly spaced scales in A. pentaprion versus gorgetal rows with 4–10 widely spaced scales in A. beckeri). Finally, SMF 83608 is proposed as the neotype for Anolis pentaprion. I provide standardized descriptions of A. beckeri, A. pentaprion, and the new species described herein.

Nesting in a thermally challenging environment: nest-site selection in a rock-dwelling gecko, Oedura lesueurii (Reptilia: Gekkonidae). Biological Journal of the Linnean Society 99(2): 250-259.


Abstract
In egg-laying species, maternal oviposition choice can influence egg survival and offspring phenotypes. According to the maternal-preference offspring-performance hypothesis, females should choose oviposition sites that are optimal for offspring fitness. However, in thermally challenging environments, maternal oviposition behaviour may be constrained by the limited availability of suitable oviposition sites. We investigated nest-site selection in a nocturnal lizard [velvet gecko Oedura lesueurii (Duméril and Bibron)] that inhabits a thermally challenging environment in south-eastern Australia. The viability of these gecko populations is critical for the persistence of an endangered snake species (Hoplocephalus bungaroides Wagler) that feeds heavily on velvet geckos. Female geckos chose nest sites nonrandomly, with 87% of nests (N = 30) being laid in deep crevices. By contrast, only 13% of clutches were laid under rocks, which were the most readily available potential nest sites. Nest success in crevices was high (100%), but no eggs hatched from nests under rocks. Temperatures in nest crevices remained relatively low and constant throughout the incubation period (mean = 22.7 °C, range 21.0–24.5 °C), whereas thermal regimes under rocks showed large diurnal fluctuations. Geckos selected crevices that were deeper, had less canopy cover, and were warmer than most available crevices; in 85% of cases, such crevices were used simultaneously by more than one female. The thermally distinctive attributes of nest sites, and their frequent communal use, suggest that nest sites are a scarce resource for female velvet geckos, and that the shading of rock outcrops through vegetation encroachment may influence nest success in this species.

Androdioecy in Kryptolebias killifish and the evolution of self-fertilizing hermaphroditism. Biological Journal of the Linnean Society 99(2): 344-349.

Abstract
Kryptolebias marmoratus is an important experimental fish, and is considered to represent the only vertebrate species comprising self-fertilizing hermaphroditic individuals. Subsequent to the discovery of this unusual mode of reproduction, approximately 50 years ago, K. marmoratus has been the focus of a series of studies. However, little is known about the evolution of this rare reproduction mode, and data on the biology of closely related species are still unavailable. The present study aimed to histologically analyse the gonads of three K. marmoratus congeners (i.e. Kryptolebias ocellatus, Kryptolebias caudomarginatus, and Kryptolebias brasiliensis) to check the distribution of features related to hermaphroditism that are useful for forming hypotheses about the origin and evolution of the self-fertilization mode of reproduction through the available phylogenies. The data obtained demonstrate that populations of K. caudomarginatus consist of males and hermaphrodites, which supports the hypothesis that hermaphroditism arose at the base of the clade containing K. caudomarginatus, K. marmoratus, and K. ocellatus as a first step towards a more advanced condition, uniquely shared by both K. marmoratus and K. ocellatus, in which males are rare or absent in natural populations, with the subsequent occurrence of self-fertilization.

Female mating preferences and male coloration covary with water transparency in a Lake Victoria cichlid fish. Biological Journal of the Linnean Society 99(2): 398-406.


Abstract
Rapid speciation in Lake Victoria cichlid fish of the genus Pundamilia may be facilitated by sexual selection: female mate choice exerts sexual selection on male nuptial coloration within species and maintains reproductive isolation between species. However, declining water transparency coincides with increasingly dull coloration and increasing hybridization. In the present study, we investigated the mechanism underlying this pattern in Pundamilia nyererei, a species that interbreeds with a sister species in turbid but not in clear water. We compared measures of intraspecific sexual selection between two populations from locations that differ in water transparency. First, in laboratory mate-choice experiments, conducted in clear water and under broad-spectrum illumination, we found that females originating from turbid water have significantly weaker preferences for male coloration than females originating from clear water. Second, both the hue and body coverage of male coloration differ between populations, which is consistent with adaptation to different photic habitats. These findings suggest that the observed relationship between male coloration and water transparency is not mediated by environmental variation alone. Rather, female mating preferences are indicated to have changed in response to this variation, constituting the first evidence for intraspecific preference-trait co-evolution in cichlid fish.

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.

"Brochis" britskii (???) 巨無霸鼠 (據說頭上點點很多但背鰭軟條數較少的) x 4
Corydoras sp. cf. blochi Manaus 灰甲鼠 x 6

雖然大多數的鼠魚愛好者仍然將Brochis當成一個分類單元, 然而Britto等人根據形態特徵所重建的親緣關係假說指出Brochis其實只是Corydoras的一個衍生群, 這也就是說, Brochis其實並不是一個有效的屬. 這樣的觀點其實已經被我們的研究與英國另一個團隊的研究結果所支持. 這也就是說, 所謂的巨無霸鼠青銅鼠的體型變大, 或是背鰭的軟條變多, 只是這幾個物種所代表的演化支系的獨有衍徵, 但並不構成Brochis被是為有別於Corydoras的理由. 所謂的青銅鼠其實是一個有趣的東西, 目前被鑑定為青銅鼠的物種分布很廣, 但是各地區的青銅鼠是否都同屬於一個物種仍有相當的疑問. 我不是非常確定吻型與頭部是否具有斑點所代表的意涵, 這部份可能要等我們有夠多的樣本才能釐清. 鼠魚研究進展之所以非常緩慢的原因主要是因為大多數在寵物市場上流通的個體的確實採集來源是不知道的, 因為這些來源並不清楚, 即使我們把非常多的"同種"個體拿去抽抽DNA, 定了序, 我們仍然無法得知遺傳上的差異倒底是"族群內"或"族群間"的差異.

那隻"頭上很多點點的巨無霸鼠"的背鰭軟條只有8-11條, 與britskii高達15-18個軟條的差異有點大, 所以那是什麼東東呢? 身上的點點讓我想起CW034, 可是這隻背鰭條只有8條的東東應該不會是CW034. 好妙啊~~~

Abstract
Molecular variation in six nuclear genes provides substantive phylogenetic evidence for the recognition of a new cypriniform family, the Ellopostomatidae, to include the enigmatic Southern Asia loach genus Ellopostoma. The current six loach families form a monophyletic group, with the Nemacheilidae as the sister group to Ellopostomatidae; Vaillantellidae forms the sister group to all families exclusive of Botiidae. While the superfamily Cobitoidea includes eight families, the monophyly of this large clade within the Cypriniformes remains a vexing problem despite extensive molecular analyses and is in need of further investigation.

(2) 隆背大暴牙對枯葉虎沒興趣? (3) 對這個種來說, 只要有餵飽, 鱗片就變得不是首要的食物來源? (4) 這個種的成魚真的對鱗片沒興趣?

Abstract
A new species of endemic, insular Cnemaspis is described from Hon Khoai Island, Ca Mau Province, Ngoc Hien District, 18 km off the southern tip of the Ca Mu Peninsula in southern Vietnam. Cnemaspis psychedelica sp. nov. is the most uniquely colored of all southeast Asian Cnemaspis in that both sexes and all age classes have bright orange forelimbs, forelegs, hands and feet; a bright orange tail; a dense, yellow reticulum on the neck overlying thick, black, longitudinal lines; and a blue-gray to light purple trunk bearing yellow transverse bars on bright-orange flanks. It also differs from all other species of Cnemaspis in aspects of size and squamation. Cnemaspis psychedelica is the third insular endemic species of Cnemaspis from Vietnam and brings the total number of species in Vietnam to six. Its occurrence on one of the 92 islands in Rach Gia Bay underscores the necessity for continued surveys of these poorly known islands that are beginning to show a surprising degree of endemism and diversity.

Abstract
We describe a new species, Hyphessobrycon sebastiani, from the San Juan River drainage of the Pacific versant of Colombia. This new species of Hyphessobrycon is distinguished from all congeners that share two humeral spots and no caudal blotch by having: five unbranched and 25 to 28 branched anal–fin rays; 12–13 branched pectoral–fin rays; 35–37 scales in the longitudinal series; eight scales between the lateral line and the dorsal–fin origin; 12–13 predorsal scales; 13–18 pored lateral–line scales and three pairs of large bony hooks on anal fin of mature males.
