ABSTRACT. Five Gobio species viz. G. battalgilae, G. gymnostethus, G. hettitorum, G. insuyanus and G. microlepidotus inhabit the Konya endorheic basin. Some studies have suggested the synonymy of G. battalgilae and G. microlepidotus based on molecular characters. Therefore, this study aimed to test the hypothesis of synonymy of G. battalgilae and G. microlepidotus. Based on our results, the morphometric and meristic characters of G. battalgilae largely overlap with those of G. microlepidotus, and we find no evidence to support the distinctiveness of the two species. Therefore, G. battalgilae Naseka, Erk'akan & Küçük, 2006 is treated as a junior synonym of G. microlepidotus Battalgil, 1942.
摘要。五种Gobio物种,即G.battalgilae、G.gymnostethus、G.hettitorum、G.insuyanus和G.microspidotus,栖息在Konya endorheic流域。一些研究根据分子特征,提出了营藻和微脊藻的同义词。因此,本研究旨在检验巴塔吉藻和微脊藻的同义假说。根据我们的研究结果,巴塔吉藻的形态计量学和分生组织特征与微棘藻有很大重叠,我们没有发现任何证据支持这两个物种的独特性。因此,G.battalgilae Naseka,Erk’akan&KüçüK,2006被视为G.microlpidotus Battalgil,1942的初级同义词。

ABSTRACT. Based on the examination of type and recently collected specimens, Moenkhausia lepidura madeirae Fowler is resurrected from the synonymy of M. intermedia and redescribed as a valid species. Moenkhausia madeirae can be diagnosed from all congeners by the following combination of characters: presence of two symmetrical dark blotches on caudal fin (one on each lobe), a conspicuous humeral blotch, 18-22 branched anal-fin rays, and mature males with two (rarely three) well-developed hooks on the last simple and first branched anal-fin rays, respectively. The species occurs in the middle and upper rio Madeira basin in Brazil and Bolivia. Comparisons are made with the other species of Moenkhausia presenting symmetrical dark blotches on the caudal-fin lobes, i.e., M. barbouri, M. bonita, M. dichroura, and M. intermedia.

ABSTRACT. Remote sensing is an invaluable tool to objectively illustrate the rapid decline in habitat extents worldwide. The many operational Earth Observation platforms provide options for the generation of land cover maps, each with unique characteristics and considerable semantic differences in the definition of classes. As a result, differences in baseline estimates are inevitable. Here we compare forest cover and surface water estimates over four time periods spanning three decades (1989–2018) for ∼1.3 million km2 encompassing the Xingu River Basin, Brazil, from published, freely accessible remotely sensed land cover classifications. While all showed a decrease in forest extent over time, the total deforested area reported by each ranged widely for all time periods. The greatest differences ranged from 9% to 17% (116,958 to 219,778 km2) deforestation of the total area for year 2000 and 2014–2018 time period, respectively. We also show the high sensitivity of forest fragmentation metrics (entropy and foreground area density) to data quality and spatial resolution, with cloud cover and sensor artefacts resulting in errors. Surface water classifications must be chosen carefully because sources differ greatly in location and mapped area of surface water. After operationalization of the Belo Monte dam complex, the large reservoirs are notably absent from several of the classifications illustrating land cover. Freshwater ecosystem health is influenced by the land cover surrounding water bodies (e.g., riparian zones). Understanding differences between the many remotely sensed baselines is fundamentally important to avoid information misuse, and to objectively choose the most appropriate classification for ecological studies, conservation, or policy making. The differences between the classifications examined here are not a failure of the technology, but due to different interpretations of ‘forest cover’ and characteristics of the input data (e.g., spatial resolution). Our findings demonstrate the importance of transparency in the generation of remotely sensed classifications and the need for users to familiarize themselves with the characteristics and limitations of each data set.
摘要。遥感是客观说明全球栖息地范围迅速下降的宝贵工具。许多运行中的地球观测平台为生成土地覆盖图提供了选择,每一个平台都具有独特的特征,在类别定义方面存在相当大的语义差异。因此,基线估计数的差异是不可避免的。在这里,我们比较了巴西新谷河流域约130万平方公里的四个时间段(1989年至2018年)的森林覆盖率和地表水估计值,这些数据来自已公布的、可自由获取的遥感土地覆盖分类。虽然所有国家的森林面积都随着时间的推移而减少,但每个国家报告的总森林砍伐面积在所有时间段内变化很大。2000年和2014-2018年期间,最大的差异分别为总面积的9%至17%(116958至219778平方公里)。我们还展示了森林破碎化指标(熵和前景区域密度)对数据质量和空间分辨率的高度敏感性,云层覆盖和传感器伪影会导致误差。必须仔细选择地表水分类,因为地表水的来源在位置和地图面积上差异很大。Belo Monte大坝综合体投入运行后,大型水库明显没有出现在几个说明土地覆盖的分类中。淡水生态系统健康受到水体周围土地覆盖的影响(例如河岸带)。了解许多遥感基线之间的差异对于避免信息滥用以及客观地为生态研究、保护或政策制定选择最合适的分类至关重要。这里检查的分类之间的差异并不是技术的失败,而是由于对“森林覆盖率”和输入数据特征(如空间分辨率)的不同解释。我们的研究结果表明,透明度在生成遥感分类中的重要性,以及用户熟悉每个数据集的特征和局限性的必要性。

ABSTRACT. A hypothesis of phylogenetic relationships is presented for species of the South American catfish subfamily Centromochlinae (Auchenipteridae) based on parsimony analysis of 133 morphological characters in 47 potential ingroup taxa and one outgroup taxon. Of the 48 species previously considered valid in the subfamily, only one, Centromochlus steindachneri, was not evaluated in the present study. The phylogenetic analysis generated two most parsimonious trees, each with 202 steps, that support the monophyly of Centromochlinae composed of five valid genera: Glanidium, Gephyromochlus, Gelanoglanis, Centromochlus and Tatia. Although those five genera form a clade sister to the monotypic Pseudotatia, we exclude Pseudotatia from Centromochlinae. The parsimony analysis placed Glanidium (six species) as the sister group to all other species of Centromochlinae. Gephyromochlus contained a single species, Gephyromochlus leopardus, that is sister to the clade Gelanoglanis (five species) + Centromochlus (eight species). Based on the new taxonomic arrangement herein, Balroglanis Grant 2015 and Sauronglanis Grant 2015 are placed in the synonymy of Centromochlus. Tatia is the most diverse genus within Centromochlinae, with twenty-six species in three monophyletic clades. The species composition of Tatia differs from that of Calegari et al. (2019). Duringlanis Grant 2015 and Ferrarissoaresia Grant 2015 are considered synonyms of Tatia. All generic taxa within Centromochlinae are diagnosed based on synapomorphic morphological characters. An identification key for Centromochlinae is provided.
摘要本文通过对南美鲶鱼centrromochlinae (Auchenipteridae) 47个群内分类群和1个群外分类群的133个形态特征的简约性分析,提出了一种系统发育关系假说。在以前认为有效的48种亚科中,只有一种没有在本研究中进行评估,即centromochus steindachneri。系统发育分析生成了两棵最简洁的树,每棵树都有202个台阶,它们支持由五个有效属组成的Centromochlinae单系:Glanidium, Gephyromochlus, Gelanoglanis, Centromochlus和Tatia。虽然这5个属与单型的pseudoatia形成了一个分支姐妹,但我们将pseudoatia排除在Centromochlinae之外。简约分析将Glanidium(6种)列为Centromochlinae所有其他物种的姊妹类群。gephyromochus包含一个单一种,gephyromochus leopardus,它是Gelanoglanis(5种)和centromochus(8种)的姐妹。根据本文的新分类安排,Balroglanis Grant 2015和Sauronglanis Grant 2015被置于Centromochlus的同义词中。Tatia是Centromochlinae中最多样化的属,在三个单系分支中有26种。Tatia的物种组成与Calegari et al.(2019)不同。Duringlanis Grant 2015和Ferrarissoaresia Grant 2015被认为是Tatia的同义词。所有属分类群都是基于突触形态特征进行诊断的。提供了一种鉴定棘球蚴的关键字。

ABSTRACT. Long-term sediment accretion and nutrient concentrations were investigated in tidal marsh sediments of the Murderkill River, Delaware. Radionuclides (210Pb and 137Cs), stable isotopes (13C and 15N), organic matter concentrations and nutrient concentrations were measured. Tidal marsh sediment accumulation rates ranged from 0.10 to 0.20 g cm-2 yr-1, and accretion rates ranged from 0.31 to 0.74 cm yr-1. The Carbon (C) to nitrogen (N) ratio (∼24) was higher in the downcore of upstream sites, and a similar C/N ratio was identified in surface sediment cores at the downstream sites. The sediment N concentration in the surface sediments was highest at the upstream sites (mostly ≥1% of N) and decreased downstream. Total nitrogen concentrations were highest from 1910 to 1920 (∼1.5% N), decreased to approximately 0.6% N by 1940, and then remained constant to present. The dominance of the C4 plant Spartina (cordgrass) over C3 plants after the 1940s may be due to an upward movement of saline water associated with hydrologic changes and a rise in relative sea level. Surface sediments in all of the cores have more total phosphorus (TP) than below ground. The downstream site closest to the estuary had an abrupt increase in surface TP (i.e., 0–10 cm). Sediment TP increased slightly from 2003 to present time (i.e., from 0.07 to 0.11% P). Sediment accumulation and accretion rates in the Murderkill River marshes are similar to the accretion rates determined by previous studies in the region.
摘要。对特拉华州Murderkill河潮汐沼泽沉积物中的长期沉积物堆积和营养物浓度进行了研究。测量了放射性核素(210Pb和137Cs)、稳定同位素(13C和15N)、有机物浓度和营养物浓度。潮沼沉积物堆积速率范围为0.10至0.20 g cm-2 yr-1,吸积速率范围为0.31至0.74 cm yr-1。上游站点的下孔中碳(C)与氮(N)之比(~24)较高,下游站点的表层沉积物岩芯中也发现了类似的C/N比。表层沉积物中的沉积物氮浓度在上游最高(大部分≥1%的氮),在下游下降。总氮浓度在1910年至1920年间最高(~1.5%氮),到1940年降至约0.6%氮,然后保持不变。1940年代后,C4植物Spartina(灯芯草)对C3植物的优势可能是由于与水文变化和相对海平面上升相关的盐水向上运动。所有岩芯中的表层沉积物的总磷含量均高于地下沉积物。最靠近河口的下游站点的表面TP突然增加(即0–10 cm)。从2003年到现在,沉积物TP略有增加(即从0.07%P增加到0.11%P)。Murderkill河沼泽地的沉积物堆积和堆积速率与该地区先前研究确定的堆积速率相似。

ABSTRACT. A capybara jaw (Rodentia, Caviidae, Hydrochoerinae) and an isolated lower tooth fragment were recovered from dredge spoils on Pelican Island in Galveston Bay, Gulf Coast of Texas. The attached matrix on the jaw and most of the dredged material is clay, indicative of the latest Pleistocene Beaumont Formation which underlies the Holocene deposits. In the latest Pleistocene (Rancholabrean) of the United States, capybaras are known from along the Gulf and Atlantic coasts in Texas, Florida, Georgia, South Carolina, and Virginia.These Rancholabrean capybaras have been assigned to three different taxa: Neochoerus pinckneyi Hay, 1923 for the largest size specimens, Hydrochoerus holmesi Simpson, 1928 for the somewhat smaller specimens, or Neochoerus aesopi Leidy, 1853, a name that had been considered invalid because it was not adequately diagnosed, if there is only one late Pleistocene species of North American capybara. The p4 in the new Texas mandible is much smaller than the genotype of N. pinckneyi from the Aransas River in South Texas and similar in size to H. holmesi from the Pleistocene of Florida and Recent H. hydrochaeris. However cheek tooth size and occlusal pattern in Recent capybaras varies significantly with age. Hydrochoerus holmesi cannot be distinguished from N. pinckneyi. None of the late Pleistocene capybaras of South Carolina, including the type and referred specimens of N. aesopi, have any characteristics to differentiate them from H. holmesi or N. pinckneyi. We therefore assign all the Texas and South Carolina specimens to N. aesopi.
摘要在德克萨斯州墨西哥湾沿岸加尔维斯顿湾鹈鹕岛的疏浚残骸中,发现了一个水豚颚(啮齿目,洞穴科,水豚科)和一个孤立的下牙碎片。颚部附着的基质和大部分疏浚物为粘土,表明其为全新世沉积物下的最新更新世博蒙特组。在美国的最新更新世(Rancholabrean),水豚在德克萨斯州、佛罗里达州、佐治亚州、南卡罗来纳州和弗吉尼亚州的墨西哥湾和大西洋沿岸被人们所知。这些Rancholabrean水豚被划分为三个不同的分类群:最大的标本Neochoerus pinckneyi Hay, 1923年,稍微小一点的标本Hydrochoerus holmesi Simpson,或者Neochoerus aesopi Leidy, 1853年,如果只有一个晚更新世的北美水豚物种,这个名字被认为是不成立的,因为它没有得到充分的诊断。新发现的德克萨斯州下颌骨中的p4比来自南德克萨斯州Aransas河的N. pinckneyi的基因型小得多,与来自佛罗里达州更新世的H. holmesi和最近的H. hydrochaeris的大小相似。然而,现代水豚的颊齿大小和咬合模式随着年龄的变化而变化。holmeshydrochoerus不能与平克尼水蚤区分开。南卡罗莱纳的晚更新世水豚,包括N. aesopi的类型和参考标本,都没有任何特征可以将它们与H. holmesi或N. pinckneyi区分开来。因此,我们将所有的德克萨斯和南卡罗莱纳标本归为伊索伊蚤。

ABSTRACT. A new species of peacock bass, Cichla cataractae, is distinguished from all congeners by molecular evidence and unique patterns of adult and juvenile pigmentation. Juveniles (<150 mm SL) have sides of body dominated by a series of three conspicuous dark blotches with the one below soft dorsal fin largest, attenuated posteriorly (long teardrop shape) but distinctly separated from elliptical caudal blotch; same blotches eventually with pale border (ocellated) in largest juveniles. Adult pattern on sides dominated by two distinct dark blotches, each one ocellated; anterior blotch rounded, located below anterior base of spinous dorsal fin and not extending above anterior lateral line; posterior blotch highly irregular in shape, located below soft dorsal fin and often displaced dorsally; additional dark blotch below posterior base of spinous dorsal fin generally absent or small, ocellated or not, and level with anterior blotch; vertical bars on sides generally absent or faint; postorbital stripe always present, highly broken into irregular series of dark spots, each one usually ocellated. Cichla cataractae is endemic to the Essequibo Basin where it typically inhabits rocky shoals in river channels with swift current. The new species is sympatric with the more widely distributed C. ocellaris, a species that prefers lentic habitats. Molecular analysis supports C. cataractae as a distinct lineage in a clade of Cichla containing C. temensis, C. melaniae, C. mirianae, C. piquiti and C. pinima. The oldest extant specimens of the new species were collected by Carl H. Eigenmann in 1908 and documented in his seminal "The Freshwater Fishes of British Guiana" (Eigenmann, 1912).
摘要通过分子证据和独特的成鱼和幼鱼色素沉着模式,将孔雀鲈鱼(Cichla cataractae)与所有同系种区分开来。幼鱼(< 150mm SL)身体两侧有三个明显的黑色斑点,其中软背鳍下方的斑点最大,后部减弱(长泪滴状),但明显与椭圆形尾端斑点分开;在最大的幼鱼中相同的斑点最终具苍白的边缘(细胞化)。两侧的成虫模式由两个明显的深色斑点占主导地位,每一个细胞;圆形的前斑点,位于棘状背鳍的前基部以下和不延伸于前侧线以上;在形状上高度不规则的后斑点,位于软背鳍下面并且经常背向移位;在棘状背鳍的后基部下面的另外的深色斑点通常无或小,细胞状与否,和与前斑点水平;在侧面的竖杆通常没有或微弱;眶后条纹总是存在,高度破碎成不规则系列的黑点,每一个通常是细胞状的。卡塔卡奇拉是埃塞奎博盆地特有的,它通常栖息在水流湍急的河道中的岩石浅滩上。这个新物种与分布更广泛的C. ocellaris是同域的,C. ocellaris是一种更喜欢在野外栖息的物种。分子分析支持C. cataractae作为一种独特的谱系,存在于包含C. temensis、C. melaniae、C. mirianae、C. piquiti和C. pinima的蛭科中。现存最古老的新物种标本由Carl H. Eigenmann于1908年收集,并记录在他的开创性著作《英属圭亚那淡水鱼》(Eigenmann, 1912)中。

ABSTRACT. We discuss new applications of baited remote underwater video (BRUV) systems based on recordings of Amazonian freshwater fauna during a long-term fish monitoring program in the Xingu River, Brazil. BRUVs facilitated estimates of relative abundance and frequency of occurrence for species of river turtles (Podocnemis unifilis, P. expansa, Rhinoclemmys punctularia), river dolphin (Inia geoffrensis) and spectacled caiman (Caiman crocodilus) in a variety of habitats including rocky rapids, submerged sandy beaches, an artificial reservoir and the Xingu Ria.
摘要。在巴西新古河的一个长期鱼类监测项目中,我们讨论了基于亚马逊淡水动物记录的带诱饵远程水下视频(BRUV)系统的新应用。BRUV有助于估计河龟(Podocnemis unifilis、P.expansa、Rhinoclemmys puncularia)、河豚(Inia geoffrensis)和眼镜凯门鳄(凯门鳄)在各种栖息地的相对丰度和出现频率,包括岩石急流、淹没的沙滩、人工水库和Xingu Ria。

ABSTRACT. Our understanding of pathological conditions is usually centered on human and domesticated species. Thus, a vast array of pathologies within vertebrates are unknown, especially those that occur in exotics and those that lack external characters, such as conditions that affect the skeleton. Exotics represent a majority of the vertebrates housed in zoos and other wildlife centers, and in the larger picture of conservation, represent the best way to determine potential health threats and cures for endangered and threatened species in the wild. Here we describe a case of acromegaly, a rare condition of excess growth hormone, in a hog badger (Arctonyx collaris) based on Computed Tomography (CT). This is the first documented occurrence of this condition in non-human or non-domesticated mammals, and the first occurrence within Mustelidae. The recognition of this rare condition within a badger suggests that acromegaly may be more widespread within mammals than previously thought, and has implications for diagnosis of other exotics within zoos.
摘要。我们对病理状况的理解通常集中在人类和驯化物种上。因此,脊椎动物体内的大量病理学是未知的,尤其是发生在外来物种中的病理学和缺乏外部特征的病理学,例如影响骨骼的疾病。外来物种代表了动物园和其他野生动物中心的大多数脊椎动物,从更大的保护角度来看,它们代表了确定潜在健康威胁和治疗野生濒危和受威胁物种的最佳方法。在这里,我们描述了一例肢端肥大症,这是一种罕见的生长激素过多的情况,在计算机断层扫描(CT)的基础上,发生在一只猪獾(锁骨Arctonyx)身上。这是首次记录到这种情况在非人类或非驯养哺乳动物中发生,也是首次在鼬科中发生。獾体内对这种罕见疾病的认识表明,肢端肥大症在哺乳动物体内可能比以前认为的更为普遍,并对动物园内其他外来物种的诊断有意义。
