Aspectos da biologia reprodutiva de Bothrops jararaca em cativeiro (Serpentes, Viperidae) Iheringia, Sér. Zool.
Alves,Maria Lúcia Machado; Leitão-de-Araujo,Moema; Witt,André Alberto.
The reproduction of Bothrops jararaca (Wied, 1824) in captivity in ordened to determine the intercourse period, births, number of neonates, proportion of males and females per litter were performed between 1989 and 1999. Fifty eight females were observed, 16 intercourses in captivity, 45 females arrived already fertilized from nature and 53 litters, resulting on the birth of 426 live neonates, 67 infertile egg masses, 18 stillborn neonates and 4 abnormal neonates. The intercourse period was from february to december and the births happened between february and may. From the two gestacional periods observed, the shortest one was 152 days and the longest 239. The average amount of live neonates per litter was 8,04. Among 323 neonates, 47,68% were males and...

Aspergillosis: a limiting factor during recovery of captive magellanic penguins BJM
Xavier,Melissa O.; Soares,Mauro P.; Meinerz,Ana Raquel M.; Nobre,Márcia O.; Osório,Luiza G.; Silva Filho,Rodolfo P. da; Meireles,Mário Carlos A..
The article describes the epidemiology, macroscopic and histological lesions as well as the isolation of Aspergillus flavus and A. fumigatus from Magellanic penguins (Spheniscus magellanicus) during recovery in the Center for Recovery of Marine Animals (CRAM - 32ºS/52ºW), over a period of two years. From January 2004 to December 2005 the Center received 52 Magellanic penguins, and 23% (12/52) died. Necropsies were performed and tissue samples were collected for histological and microbiological examination. From 12 dead animals, aspergillosis was confirmed in five animals, corresponding to 42% of the mortality. Granulomatous nodules were observed mainly on air sacs and lungs. Histologically, septate and branching hyphae, measuring 3-5 µm and PAS positive...

Behaviour of cockatiels (Nymphicus hollandicus) at two temperatures in captivity Arq. Bras. Med. Vet. Zootec.
Carvalho,T.S.G.; Zangeronimo,M.G.; Saad,C.E.P.; Alvarenga,R.R.; Assis,V.D.L.; Pereira,V.M.; Scalon,J.D.; Silva,J.P..
Behavioural studies with cockatiels (Nymphicus hollandicus) in captivity are scarce. Due to the need for appropriate management of these animals, this study was performed to examine the behaviour of cockatiels kept in captivity at two temperatures. Sixteen cockatiels were individually housed in cages (62cm high x 43cm long x 27cm wide) and fed with a commercial ration and seed mixture for psittacids. Water was provided ad libitum. The eight-day experiment was divided into two stages of four days each. In the first stage, the birds were kept at room temperature (25°C) with 70% relative humidity during 24 hours. In the next stage, they were kept at 35°C from 06:00 to 18:00h and 25°C from 18:00 to 06:00h, also at 70% relative humidity. The behaviour of the...

Changes in the fecal concentrations of cortisol and androgen metabolites in captive male jaguars (Panthera onca) in response to stress BJMBR
Morato,R.G.; Bueno,M.G.; Malmheister,P.; Verreschi,I.T.N.; Barnabe,R.C..
In the present study we determined the efficacy of the measurement of fecal cortisol and androgen metabolite concentrations to monitor adrenal and testicular activity in the jaguar (Panthera onca). Three captive male jaguars were chemically restrained and electroejaculated once or twice within a period of two months. Fecal samples were collected daily for 5 days before and 5 days after the procedure and stored at -20ºC until extraction. Variations in the concentrations of cortisol and androgen metabolites before and after the procedure were determined by solid phase cortisol and testosterone radioimmunoassay and feces dry weight was determined by drying at 37ºC for 24 h under vacuum. On four occasions, fecal cortisol metabolite levels were elevated above...

Circadian pattern of Bothrops moojeni in captivity (Serpentes: Viperidae) J. Venom. Anim. Toxins incl. Trop. Dis.
Stuginski,DR; Sant'Anna,SS; Fernandes,W; Abe,AS.
Members of the subfamily Crotalinae are considered to be essentially nocturnal and most of the data about these snakes have been collected from the field. Information on how nutritional status affects the movement rate and activity patterns is a key point to elucidating the ecophysiology of snakes. In this study, we distributed 28 lancehead Bothrops moojeni into three groups under distinct feeding regimens after a month of fasting. Groups were divided as follows: ingestion of meals weighing (A) 40%, (B) 20%, or (C) 10% of the snake body mass. Groups were monitored for five days before and after food intake and the activity periods and movement rates were recorded. Our results show that B. moojeni is prevalently nocturnal, and the activity peak occurs in...

Comportamento e preferência alimentar em Podocnemis expansa (Schweigger), P. unifilis (Troschel) e P. sextuberculata (Cornalia) em cativeiro (Testudines, Pelomedusidae) Zoologia
Malvasio,Adriana; Souza,Ana Maria de; Molina,Flavio de Barros; Sampaio,Francisco de Arruda.
The feeding behavior and the food preference was studied in P. expansa (Schweigger, 1812) P. unifilis (Troschel, 1848) and P. sextuberculata (Cornalia, 1849). The method used for feeding behavior and food preference was the sampling of all occurrences. The Students' t test was applied on the food items, to compare differences during the development of each species. The main conclusions are: feeding behavior for food, except alive animals, is divided in foraging, approach, olfactory recognition, capture, laceration and ingestion; the persecution behavior was observed for prey activity; cleptoparasitism occurs in the three species and neustophagia mechanism was detected in P. unifilis; P. sextuberculata shows to be almost only carnivorous and P. expansa and...

Description of behavioral patterns of Podocnemis erythrocephala (Spix, 1824) (Testudines: Podocnemididae) (Red-headed river turtle) in captivity, Manaus, Amazonas, Brazil Acta Amazonica
Schineider,Larissa; Ferrara,Camila; Vogt,Richard C.
The biology and ecology of South American turtles is still poorly known, particularly, for the Brazilian species. Laboratory studies are essential to understand the life cycles of aquatic turtles species and to help in formulating management plans for their conservation. As a contribution to the knowledge of Podocnemis erythrocephala species, we give a description of its species-typical behaviors, categorized as: maintenance, locomotion, feeding, agonistic and reproduction, based on captives observations of four pairs of turtles in an aquarium in Manaus, Brazil. Similarities and differences with the repertoires of other turtle species are discussed, concluding that turtles have much more complex adaptative strategies and social life than was believed.

Effects of crowding and sex on fecal cortisol levels of captive forest musk deer Biol. Res.
He,Lan; Wang,Wen-Xia; Li,Lin-Hai; Liu,Bao-Qing; Liu,Gang; Liu,Shu-Qiang; Qi,Lei; Hu,De-Fu.
BACKGROUND: Restricted space and close contact with conspecifics in captivity may be stressful for musk deer, as they are highly territorial and solitary in the wild. So we tested the effects of crowding on stress of forest musk deer (Moschus berezovskii) in heterosexual groups, using fecal cortisol analysis as a non-invasive method. 32 healthy adults during non-breeding seasons were chose as our experimental objects. Group 1 was defined as higher crowding condition, with 10-15 m²/deer (6 enclosures, 10♀ and 6♂); group 2 was defined as lower crowding condition, with 23-33 m²/deer (6 enclosures, 10♀ and 6♂). Every enclosure contained 1 male and 3 female. These patterns had been existed for years. RESULTS: The results...

Hematological values of some Bothrops species (Ophidia - Crotalidae) in captivity J. Venom. Anim. Toxins
TROIANO,J.C.; VIDAL,J.C.; GOULD,E.F.; HEKER,J.; GOULD,J.; VOGT,A. U.; SIMONCINI,C.; AMANTINI,E.; DE ROODT,A..
Blood samples of 50 healthy specimens from each of the following species: Bothrops alternatus, Bothrops jararacussu, Bothrops moojeni, and Bothrops neuwiedi diporus all kept in captivity were taken to determine the hematocrit (PCV) value, red blood cell count (RBC), total leukocyte (WBC) and differential leukocyte count, thrombocyte count, mean corpuscular volume (MCV), hemoglobin concentration (HbC), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). These hematological parameters were compared to those obtained from other Bothrops species. PCV values, RBC, hemoglobin, WBC count, and differential leukocyte count are within the range of values reported for other Bothrops species, while the thrombocyte count was...

Observações sobre o comportamento de Liolaemus occipitalis em cativeiro (Sauria, Tropiduridae) Zoologia
Bujes,Clóvis Souza; Verrastro,Laura.
Liolaemus occipitalis (Boulenger, 1885) is an abundant lizard lbundalong lhe coastal dunes of Rio Grande do Sul, Brazil. Fourteen individuais were manually captured in the dunes of Quintão beach (Palmares do Sul, Rio Grande do Sul) and studied in captivity from 23/VII/92 to 30/VII/93. They were kept in a terrarium with sand substrate and vegetation collected in their habitat. Snout-vent length (SVL) and wcighted were measured weekly. They received Tenebrio molitor (Linnaeus, 1758) worms as food; water was abundant. Combats between males for food and territory, and other behavioral displays were observed, like copulation and nesting behaviors. Growth curves for each lizard were analyzed.

Ocorrência de híbridos não naturais entre Bothrops jararaca e B. neuwiedi (Serpentes, Viperidae) Iheringia, Sér. Zool.
Balestrin,Rafael Lucchesi; Leitão-de-Araujo,Moema; Alves,Maria Lúcia Machado.
In May 1987, a female of Bothrops jararaca (Wied, 1824), from Carazinho, Rio Grande do Sul (RS), Brazil, was placed in the same vivarium with a male of Bothrops neuwiedi Wagler, 1824 coming from Guaíba, RS. There, they stayed for aproximately ten months. In March 1988, it was observed a delivery of five live and two still born, among them six presented morphologic characteristics of B. neuwiedi and one of B. jararaca. After the female died, in April 1988, through necropsy, two fetusus were found, one near the cloaca and, both identified as B. neuwiedi. The morphologic analysis and the origin of the progenitors suggest the hypothesis that the litter was resulted of cross-breeding.

Parental care in the buffy-tufted-ear marmoset (Callithrix aurita) in wild and captive groups BJB
SANTOS,C. V.; MARTINS,M. M..
Studies on cooperative care of offspring in callitrichid primates are biased in favor of observations in captivity. In the wild, however, individuals have to deal with environmental pressures, which may influence their social behavior. We compared the individual effort attributed to parental care offered by members of a wild group (couple, plus a subadult helper) and two captive groups (A: couple, plus an subadult helper, B: couple, plus four adult helpers) of the buffy-tufted-ear marmoset, Callithrix aurita, from weeks 1-12 after the infants' birth. The carrier (breeding male and female or helper) and the infant's feeding (food sharing and foraging for food) were recorded. Up to week four, while the wild breeding pair shared infant carrying at similar...

Seasonal variation in the behavior of captive alpine musk deer, Moschus sifanicus, in Xinglongshan Musk Deer Farm, of China Rev. Bras. Zool.
Xiaofeng,Luan; Changjie,Zhao; Cenyi,Hui; Xiuxiang,Meng.
Musk deer farming has the potential to be an effective conservation tool for the protection of musk deer as well as the production of valuable musk. To be successful, this requires a thorough understanding of the behavior of captive musk deer in order to improve their reproductive success and management. Between August 2005 to January 2006, the behavior sampling of 19 male and 13 female captive alpine musk deer, Moschus sifanicus Büchner, 1891, was used to examine the durations of twelve behavioral characteristics during the pre-rut (August to October) and rut seasons (November to January). Both males and females exhibited some seasonal variation in behavior. Males rested and fed more during the pre-rut than the rut and spent more time walking, fighting,...

Single large or several small? The influence of prey size on feeding performance of Philodryas nattereri (Squamata: Serpentes) Biological Sciences
Pereira, Sara Catunda; Rodrigues, João Fabrício Mota; Borges-Nojosa, Diva Maria.
This study aimed at evaluating the energetic return and feeding time on Philodryas nattereri kept in captivity. Snakes were fed biweekly for 60 days (four feeding trials), in two different feeding treatments (single and multiple prey items). The energetic return revealed no significant difference between the feeding treatments; however, we found a negative relationship between snake size and prey handling time during a feed using multiple prey items. In P. nattereri, when large preys are as easy to find as small ones, there seems to be no difference in energetic return.

Survivability of discarded Norway lobster in the bottom trawl fishery of the Bay of Biscay ArchiMer
Merillet, Laurene; Mehault, Sonia; Rimaud, Thomas; Piton, Corentine; Morandeau, Fabien; Morfin, Marie; Kopp, Dorothee.
In the context of the landing obligation set by the new Common Fisheries Policy (CFP), Norway lobster Nephrops norvegicus was identified as a species likely to have high survival rate when discarded in the bottom trawl fishery of the Bay of Biscay. Previous studies in this area reported a survival rate between 30% and 51%, but the experiments were done on a limited monitoring period and the seasonal variations were not investigated. This study was designed to obtain a reliable value for survival rate after a 14-day monitoring period in onshore tanks allowing considering delayed mortality. The study also tested the effect on the survival rate of using a discarding chute system, a sorting device that was made mandatory on the 1st of January 2017 for Nephrops...

Survival of discarded Nephrops norvegicus after trawling in the Bay of Biscay ArchiMer
Mehault, Sonia; Morandeau, Fabien; Kopp, Dorothee.
The new Common Fisheries Policy may exempt some species from the landing obligation if a high survival rate can be demonstrated among discards. This study focuses on the survival capacity of Nephrops norvegicus discarded from trawlers of the Bay of Biscay (France). Three sea trials were conducted on board 3 commercial trawlers and 15 fishing operations were sampled. The vitality of Nephrops was classed into three categories (healthy, moribund or dead) before release at sea and samples of healthy and moribund individuals were kept in captivity on Nephrops grounds for three days. A Generalised Linear Model was used to examine the variability in the proportion of healthy Nephrops discarded, which was significantly influenced by tow duration, duration of air...

The stimulatory effect of male agouti (Dasyprocta prymnolopha) on the onset of female puberty Acta Amazonica
Guimarães,Diva Anelie de Araújo; Ramos,Rosemar Silva Luz; Garcia,Gary Wayne; Ohashi,Otávio Mitio.
The objective of this research was to analyze female agouti puberty. We did not observe the onset of puberty when the females were raised without males. When an adult male was put together with other adults and no cycling females, the onset of estrous cycle was observed after 10 to 60 days. When the young females were raised with a male, the onset of puberty was reached at 9 months. We concluded that the male agouti influences the onset of puberty in females, and that the dominant female, apparently, inhibits or delays the puberty of the other agouti females of the group. We suggest further studies be made concerning the social control of the reproduction of these animal.

Tooth wear in captive rhinoceroses (Diceros, Rhinoceros, Ceratotherium: Perissodactyla) differs from that of free-ranging conspecifics Naturalis
Taylor, L.A.; Müller, D.W.H.; Schwitzer, C.; Kaiser, T.M.; Codron, D.; Schulz, E.; Clauss, M..
Tooth wear can affect body condition, reproductive success and life expectancy. Poor dental health is frequently reported in the zoo literature, and abrasion-dominated tooth wear, which is typical for grazers, has been reported in captive browsing ruminants. The aim of this study was to test if a similar effect is evident in captive rhinoceros species. Dental casts of maxillary cheek teeth of museum specimens of captive black (Diceros bicornis; browser), greater one-horned (Rhinoceros unicornis; intermediate feeder) and white rhinoceroses (Ceratotherium simum; grazer) were analysed using the recently developed extended mesowear method for rhinoceroses. Captive D. bicornis exhibited significantly more abrasion-dominated tooth wear than their free-ranging...

Variação de peso e sobrevida de Micrurus corallinus sob diferentes condições de alimentação em biotério (Serpentes, Elapidae) Iheringia, Sér. Zool.
Serapicos,Eliana de Oliveira; Merusse,José Luiz Bernardino.
The weight variation in Micrurus corallinus (Merrem, 1820) during the first 60 days in laboratory animal rooms was very remarkable. This fact demonstrates the difficulty in adaptation of these animals to the captive environment. The weight loss was observed in animals under voluntary feeding as well as forced feeding. The survival rate was significantly higher in voluntarily fed animals. Sex differences were also observed with higher survival rates for males. Low survival rates were observed in both sexes under forced feeding.
