Yawning is a widely recognized behavior in mammalian species. One would expect that elephants yawn, although to our knowledge, no one has reported observations of yawning in any species of elephant. After confirming a behavioral pattern matching the criteria of yawning in two Asian elephants (Elephas maximus) in a zoological setting, this study was pursued with nine captive African elephants (Loxodonta africana) at a private reserve in the Western Cape, South Africa, the Knysna Elephant Park. Observations were made in June-September and in December...

The level of convergence between a rodent, the South American lowland paca Cuniculus paca, and a ruminant, the African water chevrotain Hyemoschus aquaticus, is analysed using 231 characteristics belonging to different biological sectors. A convergence index is established based on the degree of rarity of each characteristic in each species compared to other members of its zoological group. Although the divergent characteristics are as numerous as the convergent ones, the two species are globally similar. Convergent characteristics occur in all biological categories, but their rate varies a great deal among them...

This study is focused on the Chinese fauna of the leaf beetle genus Chlamisus Rafinesque, 1815 (Coleoptera: Chrysomelidae) and three new species are described, namely C. corollinotatus sp. nov. from Guangxi, and C. lycocephalus sp. nov. and C. varipennatus sp. nov. from Yunnan. The number of the Chinese Chlamisus is thus increased to 66. Twenty-five species are redescribed with the emphasis mainly on the genital morphological characters that are observed and reported for the first time for most species of the genus from China...

Acantholycosa Dahl, 1908 is relatively large genus of wolf spiders with 28 named species and one subspecies (World Spider Catalog 2016) distributed in the Holarctic, though the majority of its species (24) is known from Russia. Although the genus is well studied due to several revisions (Marusik et al. 2004; Marusik & Omelko 2011; Omelko et al. 2016), its real species diversity remains unknown. A recent study of the collections of the Zoological Museum of Moscow State University revealed one undescribed species from Khabarovsk Province of Russia, belonging to the A...

During travel made in February and March 1882 in the former French Protectorate of Côte d'Or (southeastern Ivory Coast), Mr Chaper, who had previously sent numerous specimens to the Paris Natural History Museum (Muséum national d'Histoire naturelle, Reptiles & Amphibiens; MNHN-RA), collected about 19 reptiles (and one python egg) belonging to 12 species. All those specimens were deposited in the MNHN-RA collections. Among them some specimens were described as a new species, Euprepes chaperi, in two separate publications reporting on that collection published in the same year by Vaillant (1884a,b), head of the Zoology (Reptiles and Fishes) Laboratory at Paris Natural History Museum...

The Swedish marine nematologist Carl Allgén (1886-1960) published 185 scientific papers on parasitic, terrestrial, limnic and especially marine nematodes between 1921 and 1960. Among them are also some papers on species of suctorians found mostly on desmodorid nematodes. He described about 70 new genera and over 800 new species and subspecies of nematodes. Allgén left a large collection of nematodes to the Swedish Museum of Natural History in Stockholm and it is now deposited in the invertebrate collection of the Zoology department...

Dahanukar et al. (2016a) proposed the nomen Walkerana for a new genus of amphibians, but shortly after (2016b) they replaced it by the new nomen Sallywalkerana, believing that their nomen Walkerana was preoccupied by a generic nomen of orthopterans. This was unjustified because the orthopteran nomen 'Walkerella' Otte & Perez-Gelabert, 2009a and its new replacement nomen 'Walkerana' Otte & Perez-Gelabert, 2009b were both nomina nuda. These recent examples of nomenclatural errors in generic nomenclature are just a few among many in recent zootaxonomic publications...

In this study we describe two new species of cavicolous-straminicolous crickets for southern Brazil. Endecous chape n. sp. and E. naipi n. sp. are sympatric crickets that inhabit the Atlantic Semideciduous Forest of the Iguaçu National Park and adjacent areas. The descriptions were based on morphological characters, mainly from male genitalia and tegmina of adult males. Furthermore, we describe the chromosomes and the calling song of one of the new species, E. chape n. sp., presenting a discussion about the morphology of the phallic complex of Endecous and a distribution map for the species of the genus...

BACKGROUND: Avian malaria parasites (Plasmodium spp.) and related haemosporidians (Haemosporida) are responsible for diseases which can be severe and even lethal in avian hosts. These parasites cause not only blood pathology, but also damage various organs due to extensive exo-erythrocytic development all over the body, which is not the case during Plasmodium infections in mammals. However, exo-erythrocytic development (tissue merogony or schizogony) remains the most poorly investigated part of life cycle in all groups of wildlife haemosporidian parasites...

Polypharmacy is a term that describes the inappropriate, concurrent use of multiple drugs in an individual patient. Zoological medicine practitioners must take approved agents (veterinary or human) and extrapolate their use to non-approved species often with little species-specific pharmacological evidence to support their decisions. When considering polypharmacy, even less information exists concerning multi-drug pharmacokinetics, pharmacodynamics, or potential drug-drug interactions in non-domestic species...

We report epidemic occurrences of fatal salmonellosis caused by Salmonella Enteritidis in captive maras (Dolichotis patagonum) in a zoological garden in Japan. The deaths were sudden or followed a peracute course within a few hours of the first observations of clinical abnormalities. Gross lesions included haemorrhages in the subcutis and skeletal muscles, liver, spleen, lung, heart and gastrointestinal tract. Microscopically, there were haemorrhagic and necrotizing lesions with gram-negative bacilli in the liver, spleen, small intestine and Peyer's patches...

150 years ago, in 1866, Ernst Haeckel published a book in two volumes called "Generelle Morphologie der Organismen" (General Morphology of Organisms) in which he formulated his biogenetic law, famously stating that ontogeny recapitulates phylogeny. Here we describe Haeckel's original idea and follow its development in the thinking of two scientists inspired by Haeckel, Alexei Sewertzoff and Adolf Naef. Sewertzoff and Naef initially approached the problem of reformulating Haeckel's law in similar ways, and formulated comparable hypotheses at a purely descriptive level...

Visitors to zoological collections can have substantial effects on captive animals that vary according to species, enclosure design, visitor proximity, and husbandry methods. One particularly intense form of visitor interaction occurs in immersive exhibits such as walk-through enclosures. Such enclosures are increasingly common but effects on animal behavior are currently understudied. Here, the behavior of captive European red squirrels (Sciurus vulgaris) is studied in relation to visitor numbers in a walk-through enclosure...

Toxoplasmosis, caused by the protozoan Toxoplasma gondii, is one of the most widespread zoonoses in the world. It can affect most warm-blooded animals but only felids are its definitive hosts. We determined seroprevalence and associated risk factors in birds and mammals kept in two zoological parks in northern Portugal. Sera from 77 birds and 42 mammals were assayed for the presence of T. gondii antibodies by the modified agglutination test (MAT, cut-off titre 20); 34.5% (41/119) were seropositive. All seropositive animals were apparently healthy except one seropostive mandarin (Aix galericulata) which had chorioretinitis...

In September 2012, five Bolivian squirrel monkeys housed in a zoological park died within sequential several days without obvious clinical signs. In a necrospy, one monkey presented swelling of the kidney with multifocal white nodules in the parenchyma, and other two had pulmonary congestion. Histopathologically, multifocal bacterial colonies of gram-negative coccobacillus were found in the sinusoid of the liver in all monkeys examined (Nos.1-4). Additionally, purulent pyelonephritis, pneumonia and disseminated small bacterial colonies in blood vessels were observed...

From 1814 to 1831, the Prussian naturalist Friedrich Sellow collected 263 mammals in Brazil and Uruguay. Upon receiving the specimens, the curator of the Berlin Zoological Museum, Martin Lichtenstein, removed the original labels and replaced with ones containing more generalized locations. As a consequence, several type specimens have now dubious type localities. We examined these types as well as geographically restricted mammals collected by Sellow. In some cases, there are inconsistencies between the specimen label and the collection catalog regarding the collecting locality...
