Eleanor E Woolway, Anne E Goodenough
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...

Eight species of squat lobsters of the genus Uroptychus are reported from the western Atlantic based on the collections of the Museum of Comparative Zoology at Harvard, the Smithsonian Institution and Texas A&M University. Uroptychus nitidus (A. Milne-Edwards, 1880) is reviewed and redescribed, with a syntype taken at Blake Station 200 off Martinique designated as the lectotype. Uroptychus alphonsei n. sp. is named for U. nitidus variety C Chace, 1942, U. fenneri n. sp. for U. nitidus variety A Chace, 1942, and U...

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...

An opinion piece was recently published in this journal which, remarkably, is less than one page in length, but has 493 authors (signatories) and has gained over 15 thousand reads on ResearchGate in a very short time. Ceríaco et al. (2016) argue for a blanket ban to be imposed on the uncommon practice of basing new species descriptions in zoology on photographic evidence only of the animal. I herein aim to show that their argument is a non sequitur, i.e. their stated reasons do not support their desired conclusion...

The type specimens of the bee genus Hylaeus Fabricius, 1793 described by Ferdinand Morawitz from Asia and deposited in the Zoological Museum of the Moscow State University and in the Zoological Institute, Russian Academy of Sciences St. Petersburg, are critically reviewed. Precise information with illustrations of types for 39 taxa is provided. New synonymy is established for Hylaeus incongruus Förster, 1871 (= H. biareolatus Morawitz, 1876, syn. nov.); H. breviceps Morawitz, 1876 (= H. bivittatus Morawitz, 1876, syn...

Following the publication of Kirwan et al. (2016), it has been brought to our attention that the treatment of any possible alternative genus-group name for Parus pipra Linnaeus, 1758, when treated as monotypic, was not as self-evident to others as it was to the authors. As there is no "case law" in Zoological Nomenclature, and whatever conclusions we reached were naturally subject to our interpretation of the Code (ICZN 1999), and may not necessarily accord with the views of others, we have revisited "Pythis Viell...

Lillian E Ciardelli, Alexander Weiss, David M Powell, Diana Reiss
Although the field of animal personality research is growing, information on sea lion personality is lacking. This is surprising as sea lions are charismatic, cognitively advanced, and relatively accessible for research. In addition, their presence in captivity and frequent interactions with humans allow for them to be closely observed in various contexts. These interactions provide a valuable and unique opportunity to assess dimensions of their personality. This study created a personality survey for captive California sea lions (Zalophus californianus) using a 3-step approach that balances comprehensiveness and comparability to other species...

BACKGROUND: Monogeneans are flatworms (Platyhelminthes) that are primarily found on gills and skin of fishes. Monogenean parasites have attachment appendages at their haptoral regions that help them to move about the body surface and feed on skin and gill debris. Haptoral attachment organs consist of sclerotized hard parts such as hooks, anchors and marginal hooks. Monogenean species are differentiated based on their haptoral bars, anchors, marginal hooks, reproductive parts' (male and female copulatory organs) morphological characters and soft anatomical parts...

Geoffrey B Read, Harry A Ten Hove, Yanan Sun, Elena K Kupriyanova
As a service to taxonomists and ecologists using names in the well-known and species-rich ship-fouling serpulid genus Hydroides we present an update of all 107 non-synonymised scientific names, with additional information on Hydroides nomenclature, original names, etymologies, and type localities derived from original literature, and in accord with the World Register of Marine Species (WoRMS) database. An update is needed because the gender of genus Hydroides has from 1 January 2000 reverted to the original feminine, due to a change in the wording of International Code of Zoological Nomenclature which was overlooked at that time, and is contrary to the usage in practice of Hydroides as masculine which had started about 1992, although Code-required from the 1960s...

The monotypic colubrid snake genus Wallophis is revalidated and rediagnosed. Partial sequence for nuclear gene Oocyte maturation factor Mos (c-mos), mitochondrial Nicotinamide adenine dinucleotide dehydrogenase subunit 4 (ND4) and cytochrome b (cyt b) were used to assess phylogenetic relationship. Wallophis brachyura type species for the genus was found to be a member of the Western Palearctic clade of Colubrinae and is recovered as a sister taxa to Wallaceophis gujaratensis. Wallophis differs from Wallaceophis in an uncorrected pairwise p-distance of 17% for mitochondrial ND4 gene...

The California sea lion (Zalophus californianus), is an agile and powerful swimmer. Unlike many successful swimmers (dolphins, tuna), they generate most of their thrust with their large foreflippers. This protocol describes a robotic platform designed to study the hydrodynamic performance of the swimming California sea lion (Zalophus californianus). The robot is a model of the animal's foreflipper that is actuated by motors to replicate the motion of its propulsive stroke (the 'clap'). The kinematics of the sea lion's propulsive stroke are extracted from video data of unmarked, non-research sea lions at the Smithsonian Zoological Park (SNZ)...

BACKGROUND: Indigenous cultures are the result of their adaptation to the natural surroundings, in such a way that, amongst their main features is a set of knowledge, technologies and strategies for the appropriation of nature. In Cuetzalan del Progreso, Puebla, Mexico snakes represent 71.1% of the total local herpetofauna; and in addition to this, different groups of Nahuas have shown to have information of their use of various snake species in many ways. This study was conducted to investigate the traditional uses of snakes in this cultural group...

BACKGROUND: Spermatozoa are stored in the oviductal functional sperm reservoir in animals with internal fertilization, including zoologically distant classes such as pigs or poultry. They are held fertile in the reservoir for times ranging from a couple of days (in pigs), to several weeks (in chickens), before they are gradually released to fertilize the newly ovulated eggs. It is currently unknown whether females from these species share conserved mechanisms to tolerate such a lengthy presence of immunologically-foreign spermatozoa...

This study was performed to provide information on Tricholipeurus balanicus (Werneck 1938) detected on slender-horned gazelles (Gazella leptoceros) (Cuvier 1842). Four slender-horned gazelles kept in the El Hamma Zoological Garden in Algeria were examined for lice in April 2015. Three of the four gazelles were infested with lice; of 37 lice collected from the infested animals, 14 were females, 16 were males, and 7 were nymphs. Lice were mainly found on the back and hind legs of the gazelles. The lice were collected by a forceps, preserved in 70% alcohol, and cleared in 10% KOH for 24 h...

The sulcata or African spurred tortoise (Centrochelys sulcata) is a large tortoise species that is commonly kept in zoologic collections and as a pet. The objectives of this study were to establish reference intervals for selected biochemical analytes in clinically healthy captive sulcata tortoises and to evaluate the impact of blood sampling site and sex. Blood samples were collected from 60 tortoises from either the dorsal coccygeal (tail) vein or the subcarapacial venous plexus based on their body size. The packed cell volume and refractometric total solids (TS) were determined...
