The Brown Leaf Lizard Stenocercus caducus (Cope, 1862) (Squamata: Tropiduridae) arguably is the most widely distributed of the more than 60 species of Stenocercus Duméril and Bibron, 1859 (Nogueira and Rodrigues 2006, TorresCarvajal 2007, Torres-Carvajal and MaflaEndara 2013). It is found in forested habitats in Paraguay, Brazil, Bolivia, and Argentina; although it is a common lizard, its habits are poorly known owing to its cryptic behavior (Scrocchi et al. 1985, Ávila et al. 2008, Cacciali and Rumbo 2008, Silva et al. 2010). Little is known about the nesting behavior in this species, but limited data available suggest that they are sexually dimorphic and reproduce in the rainy season, laying a clutch of two to four eggs (Ávila et al. 2008, Cacciali and Rumbo 2008).

棕叶蜥蜴Stenocercus caducus(Cope,1862)(角鲨目:热带蜥蜴科)可以说是Stenocerus Duméril和Bibron的60多种物种中分布最广泛的,1859年(Nogueira和Rodrigues 2006,TorresCarvajal 2007,Torres-Carvajal和MaflaEndara 2013)。它分布在巴拉圭、巴西、玻利维亚和阿根廷的森林栖息地;尽管它是一种常见的蜥蜴,但由于其神秘的行为,它的习性鲜为人知(Scrocchi等人,1985年,Ávila等人,2008年,Cacchali和Rumbo 2008年,Silva等人,2010)。人们对该物种的筑巢行为知之甚少,但现有的有限数据表明,它们是两性异形的,在雨季繁殖,产下两到四个卵(Ávila等人,2008年,Caccali和Rumbo,2008年)。这

Flesh-fy myiasis (Diptera: Sarcophagidae) in Dendropsophus schubarti (Anura: Hylidae) from Peru 秘鲁舒氏树蝇的肉蝇病(双翅目:麻蝇科)
IF 0.4 4区 生物学 Q4 ZOOLOGY Pub Date : 2019-12-17 DOI: 10.11606/issn.2316-9079.v18i2p277-281

Sarcophagidae is a fly family that feeds on decomposed organic material, and some species occasionally parasitize invertebrates and vertebrates (Guimarães and Papavero 1999) by depositing larvae on the host. The larvae then feed on the host’s tissues, which include either fresh or dead tissues, corporal fluids, or ingested food (Zumpt 1965). Two types of myiasis are recognized. In primary myiasis, the larvae penetrate through intact skin or natural holes, whereas in secondary or tertiary myiasis, they use trauma or wounds to infiltrate the tissue (Soler-Cruz 2000, Francesconi and Lupi 2012). Myiasis is well documented in humans, domestic animals, mammals, and wild birds (Acha and Zsyfres 2003). However, there are also dipterans that infest ectothermic vertebrates such as Anolisimyia blakeae Dodge, 1955 (Sarcophagidae) in reptiles (Dodge 1955).

麻蝇科是一种以腐烂的有机物为食的蝇科,有些种类偶尔会寄生在无脊椎动物和脊椎动物身上(guimar和Papavero 1999),将幼虫寄生在宿主身上。然后幼虫以宿主的组织为食,包括新鲜或死亡的组织、体液或摄入的食物(Zumpt 1965)。蝇蛆病有两种类型。在初级蝇蛆病中,幼虫穿透完整的皮肤或天然孔洞,而在二级或三级蝇蛆病中,它们利用创伤或伤口渗透组织(Soler-Cruz 2000, Francesconi和Lupi 2012)。蝇蛆病在人类、家畜、哺乳动物和野生鸟类中有充分的记录(Acha和Zsyfres 2003)。然而,也有双翅目昆虫寄生于变温脊椎动物,如Anolisimyia blakeae Dodge, 1955 (Sarcophagidae)和爬行动物(Dodge 1955)。在欧洲和北美的两栖动物中

Rediscovering Cycloramphus bandeirensis (Anura: Cycloramphidae): natural history and breeding biology of a vulnerable species with a variant reproductive mode. We present here data on the breeding biology of Cycloramphus bandeirensis, including descriptions of the advertisement call and tadpole. Males call from beneath rocks in open grasslands above approximately 2,450 m a.s.l. at the Parque Nacional do Caparaó, southeastern Brazil. Breeding occurs from late October–December, when mist and clouds frequently cover the area. The advertisement call consists of a frst note, followed by two or three shorter ones. The spawn is hidden under rocks from which the males call, and the tadpoles are exotrophic and semiterrestrial. This report of a semiterrestrial tadpole that develops in seclusion in a terrestrial habitat is a variant of Reproductive Mode 19. We compared the ontogeny of the semiterrestrial tadpole of C. bandeirensis to that of generalized tadpoles, and a new function is ascribed to the skin fap that is present in larvae of Cycloramphus. It is suggested that C. bandeirensis be transferred to Vulnerable category (VU, d2) of IUCN; the species has a small geographic range (< 20 km2 ), specialized environmental requirements, is vulnerable, has phylogenetic affnities to species that consistently have undergone local population crashes in southeastern Brazil, and is subject to plausible potential threats in its range (e.g., fres and climate change).
重新发现环轮虫(无尾目:环轮虫科):一种具有变异繁殖模式的脆弱物种的自然史和繁殖生物学。本文介绍了小圆蝽的繁殖生物学,包括广告叫声和蝌蚪的描述。在巴西东南部的国家公园Caparaó,雄性狒狒在海拔2450米以上的开阔草原上的岩石下鸣叫。繁殖发生在10月下旬至12月,此时雾和云经常覆盖该地区。广告电话由第一个音符组成,然后是两三个较短的音符。卵隐藏在雄性蝌蚪发出叫声的岩石下,蝌蚪是外养和半陆栖的。本文报道了一种在陆地栖息地隐居发育的半陆栖蝌蚪,它是繁殖模式19的一种变体。我们比较了半陆栖小蝌蚪与泛陆栖小蝌蚪的个体发育,认为环头小蝌蚪幼虫的皮瓣具有一种新的功能。建议将其划入IUCN易危类(VU, d2);该物种地理分布范围小(小于20平方公里),环境要求特殊,易受伤害,在系统发育上与巴西东南部一直经历当地种群崩溃的物种有亲缘关系,并且在其分布范围内受到可能的潜在威胁(如森林和气候变化)。

Prevalence and pathology of Lernaea cyprinacea (Crustacea: Lernaeidae) parasitizing tadpoles of Pelophylax bedriagae (Anura: Ranidae) in Antalya, Turkey. This is a report of the first record of the occurrence of Lernaea cyprinacea on tadpoles of Pelophylax bedriagae, a frog species native from Karpuzçay Creek, Antalya, Turkey. A total of 20 tadpoles of P. bedriagae were examined and 14 (70%) specimens were infected. A maximum of two parasites per host was found, primarily around the cloaca. In general, slight to moderate hyperemia was noticed around the parasite. Typically, granuloma form in the tissues around the parasite. Histopathological examination revealed that hemorrhages and pathological lesions such as dermal erosions, and a chronic inflammatory reaction in skin and muscle were present at the site of parasite attachment.

Behavioral adaptations in Ameivula ocellifera (Squamata: Teiidae) in response to thermal environmental changes 对热环境变化的行为适应

Behavioral adaptations in Ameivula ocellifera (Squamata: Teiidae) in response to thermal environmental changes. Lizards rely on external sources to regulate body temperature, but in many species, it is not known whether lizards are able to change their thermoregulatory behaviors in response to variations in thermal environments. The seasonal thermal ecology of three populations of the Brazilian whiptail lizard, Ameivula ocellifera, in northeastern Brazil (two Caatinga sites and one in the Atlantic Forest) was investigated. The relationships between body temperature and microhabitat temperatures (substrate and air), and between body temperature and thermoregulatory behavior (i.e., time of exposure to sunlight classes and time spent basking) were explored. The average body temperatures of the lizards were 38–39°C; these neither varied seasonally nor among populations. Substrate and air temperatures are lower at the natural Caatinga site, and lizards in there spent less time in the shade and more time exposed to the sun. Microhabitat temperatures vary seasonally in natural Caatinga; they are lower in the rainy season, when lizards spent more time exposed to sun and less time in fltered sun. Lizard body temperatures exceeded microhabitat temperatures in the rainy season in all three populations; however, they did not exceed substrate temperature in the dry season. In each of the populations, lizards with low body temperatures during cloudy conditions spent more time basking. Thus, A. ocellifera adjusts its body temperature behaviorally to compensate for seasonal changes in environmental temperatures, as well as geographic thermal variation throughout its range.
锥虫对热环境变化的行为适应。蜥蜴依靠外部来源来调节体温,但在许多物种中,尚不清楚蜥蜴是否能够根据热环境的变化改变体温调节行为。对巴西东北部三个巴西鞭尾蜥蜴种群(两个Caatinga地点和一个大西洋森林)的季节性热生态进行了调查。研究了体温与微生境温度(基质和空气)之间的关系,以及体温与体温调节行为(即暴露在阳光下的时间和晒太阳的时间)之间的联系。蜥蜴的平均体温为38–39°C;这些变化既不随季节变化,也不随人口变化。Caatinga自然栖息地的基质和空气温度较低,那里的蜥蜴在阴凉处的时间较少,暴露在阳光下的时间较多。天然Caatinga的微栖息地温度随季节变化;在雨季,蜥蜴暴露在阳光下的时间更多,而在阳光下呆的时间更少,它们的温度更低。在雨季,所有三个种群的蜥蜴体温都超过了微栖息地的温度;然而,它们在旱季没有超过基质温度。在每个种群中,多云条件下体温较低的蜥蜴都会花更多时间晒太阳。因此,A.ocellifera通过行为调整体温,以补偿环境温度的季节变化,以及整个范围内的地理热变化。

Geographic variation in the morphology of the sand-dwelling lizard Nothobachia ablephara (Squamata: Gymnophthalmidae). Nothobachia ablephara is a small microteiid lizard with an elongated body and reduced limbs; it occurs in isolated dune felds in the state of Bahia (Xique-Xique and Alagoado) and small sandy patches in northeastern Brazil. A previous molecular study found a marked mtDNA divergence between populations of N. ablephara from Alagoado and Xique-Xique dunes, suggesting that the two populations diverged from one another between 3 and 4 million years ago. Given this isolation, it is interesting to explore whether morphological traits of the lizards refect the reported genetic divergence of the populations. Scale counts of the sexes and the populations differ signifcantly, but there is considerable overlap of values. Univariate and multivariate analyses revealed signifcant morphometric variation between sexes and populations; however, this is mostly explained by size differences. Females are larger than males in all characters that are sexually dimorphic, and individuals from Xique-Xique are larger than those from Alagoado in all characters that vary geographically. The sample from Alagoado has more sexually dimorphic characters than the one from Xique-Xique. Although N. ablephara displays some geographical variation, the two populations could not be unequivocally distinguished by scale counts and morphometric data.
沙栖蜥蜴Nothobachia ablephara形态的地理变异。阿氏Nothobachia ablephara是一种小型微型蜥蜴,身体细长,四肢缩小;它出现在巴伊亚州(锡克锡克和阿拉戈多)的孤立沙丘长石和巴西东北部的小沙地中。之前的一项分子研究发现,阿拉戈多和西克-西克沙丘的阿氏猪笼草种群之间存在显著的mtDNA差异,这表明这两个种群在300万至400万年前就存在差异。鉴于这种孤立性,探索蜥蜴的形态特征是否反映了所报道的种群的遗传差异是很有趣的。性别和人口的量表计数差异很大,但数值有相当大的重叠。单变量和多变量分析显示,性别和人群之间存在显著的形态计量学差异;然而,这主要是由尺寸差异来解释的。在所有两性异形的角色中,雌性都比雄性大,在所有不同地理位置的角色中来自西克西克的个体都比来自阿拉戈多的个体大。阿拉戈阿多的样本比西克西克的样本具有更多的两性异形特征。虽然阿氏猪笼草显示出一些地理变异,但通过数量表和形态计量数据无法明确区分这两个种群。

Delayed escape responses of male Basiliscus plumifrons (Squamata: Corytophanidae) during peak activity 在活动高峰时,雄性扁蛇蜥的延迟逃逸反应
IF 0.4 4区 生物学 Q4 ZOOLOGY Pub Date : 2019-12-17 DOI: 10.11606/issn.2316-9079.v18i2p185-193

Delayed escape responses of male Basiliscus plumifrons (Squamata: Corytophanidae) during peak activity. Many animals must balance their time spent active in a habitat against their perceived risk of predation. Factors that may increase that perceived risk, such as a faster predator approach, are therefore expected to cause prey to initiate escape quickly to avoid capture. At the same time, because patterns of daily activity can fluctuate throughout the day, the relative costs and benefits of initiating escape may also differ over time. Here I evaluated the escape responses of adult male emerald basilisk (Basiliscus plumifrons) lizards in two different time periods: morning (when daily activity peaks) and early afternoon (when activity is suppressed). Further, I approached each lizard at either a practiced slow or fast pace. Escape responses were recorded as flight-initiation (distance between observer and lizard prior to escape) and flight (distance travelled during escape) distance. No factor affected flight distance, and approach speed also had no effect on flight initiation distance. In contrast, time period affected flight initiation distance, with males approached in the morning delaying their escape response compared to males approached during the early afternoon. Because morning and early afternoon periods coincide with peak and suppressed periods of activity for basilisks at this study site, respectively, ambushforaging species like B. plumifrons may delay escape when active to avoid prematurely alerting the predator of their presence.
雄性木槿(Squamata:Corytophanidae)在活动高峰期的延迟逃逸反应。许多动物必须平衡它们在栖息地活动的时间与被捕食的风险。因此,可能增加感知风险的因素,如捕食者更快的接近,预计会导致猎物迅速逃跑以避免被捕获。同时,由于日常活动的模式可能在一天中波动,启动逃跑的相对成本和收益也可能随着时间的推移而不同。在这里,我评估了成年雄性祖母绿罗勒蜥蜴在两个不同时间段的逃跑反应:早上(当日常活动达到峰值时)和下午早些时候(当活动受到抑制时)。此外,我以练习过的慢或快的速度接近每只蜥蜴。逃跑反应被记录为飞行开始(逃跑前观察者和蜥蜴之间的距离)和飞行(逃跑期间行进的距离)距离。没有任何因素影响飞行距离,进近速度对飞行起始距离也没有影响。相比之下,时间段影响了飞行起始距离,与下午早些时候接近的雄性相比,早上接近的雄性推迟了逃跑反应。由于上午和下午早些时候分别与该研究地点的巴西利斯活动高峰期和抑制期相吻合,像B.plymifrons这样的埋伏觅食物种在活动时可能会推迟逃跑,以避免过早地提醒捕食者它们的存在。
