Herein, we used two species of ants ( Camponotus sp. and Gnamtogenys sp.) with distinct defensive mechanisms to test the predatory behavior of Phyllodytes luteolus . The experiment was conducted with frogs inhabiting a patch of 20 bromeliads ( Aechmea cf. blanchetiana ). Ants were offered randomly to the frogs until we obtained 10 observations of predation of each ant species. We observed and recorded the time that P. luteolus needed to keep each ant species inside its mouth before it could ingest it. Predatory behavior was highly distinct. While Camponotus were caught and swallowed within six seconds and without apparent discomfort, individuals of P. luteolus had more difficulty in swallowing Gnamtogenys individuals, the time of manipulation ranging from 57 to 177 seconds. The mean values of time of predation observed in each treatment was highly significant (p<0.001). We conclude that differences found in the time of manipulation are highly correlated with defense mechanisms of each species of ants.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2017-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77861713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationships between the degree of dietary overlap and food availability, and implications for food selectivity of fish species were evaluated at floodplain lakes on the upper Parana River floodplain. The hypothesis tested were: i) species become less selective in lakes with high availability of food resources; ii) species present higher food overlap in conditions of high availability of food resources; and iii) individuals of the species, become less specialized, in this case the food overlap will be high in conditions of more availability of food resources. In general, with the results was observed that species become less selective when the environment provided higher availability of food resources. Interspecific overlap did not show a pattern when evaluating availability of food resources in the lakes. However, intraspecific overlap tended to be more accentuated in conditions of high availability of resource food.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2017-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84526499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jenynsia multidentata Jenyns, 1842 (one-sided livebearers) are euryhaline viviparous fish of small size, used in the laboratory experiment, important as resource for biological control of mosquito’s larva and a key species to recover eutrophic lakes. Works have been published dealing with parasite biodiversity of this host, but little as been study about the parasite community ecology. From early 2009 to ends of 2010 specimens of J. multidentata were collected from two places, the Salado Relief Channel (S.R.C.) on Samborombon Bay and the Sauce Chico River near to the city of Bahia Blanca (B.B.). All fish were sexed, measured and grouped into sizes/age classes. The fishes from both sites harbored 16 parasitic species: nine digenean, one monogenean, one metacestode, one acanthocephalan, two nematode and two copepods . Lecithaster confusus Odhner, 1905, the metacercariae Hemiuridae gen. sp. indet., metacercariae Thylodelphys Diesing, 1850 (inside the eye), Glossocercus sp., Chandler, 1935 nematode L4 (intestine) and de Ergasilus sieboldii Nordmann, 1832 , are new records for the host. The high number of larval stages made of this fish a link between micro and macroecosystems. The size 2 had the higher biodiversity in both sites, which could be the most suitable age to store the maximal number of parasite of the environment and have a more equitability in their distribution on the host. In B.B. some parasites had higher prevalence and mean abundance due to the small size of the waterbody compared with the S.R.C. Despite that, in S.R.C. exist a higher specific richness and biodiversity due the daily flow of saline and freshwater and proximity of the sample site to the mouth of the channel in the bay. This is the first approximation to an analysis of the parasitic ecology on this host.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2017-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1590/1678-4766E2017024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72411313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A area de estudo esta localizada na regiao do Seringal Etelvi, porcao sudoeste da Reserva Extrativista Chico Mendes, municipio de Brasileia, estado do Acre. A coleta de dados ocorreu entre outubro de 2011 e setembro de 2012, num total de 48 dias de amostragem com os metodos de procura limitada por tempo e armadilhas de interceptacao e queda. Foram registrados 978 especimes de 31 especies de anfibios e 54 de repteis. Maior riqueza e abundância de anfibios ocorreram durante o periodo chuvoso, ambas correlacionadas positivamente com todas as variaveis selecionadas. Apenas a abundância de repteis foi maior durante o periodo chuvoso, nao havendo correlacao da riqueza e abundância com as variaveis climaticas selecionadas. Tres anfibios ( Rhinella marina (Linnaeus, 1758) , Adenomera hylaedactyla (Cope, 1868) e Allobates femoralis (Boulenger, 1884 “1883”)) e dois repteis ( Kentropyx penviceps Cope, 1868 e Norops fuscoauratus (D’Orbigny, 1837)) tiveram suas abundâncias mensais correlacionadas com variaveis climaticas. Foi possivel verificar o aumento da riqueza e abundância de anfibios e repteis durante periodos em que a disponibilidade de recursos e favoravel para muitas especies.

Biometry of neotropical invertebrates inhabiting floodplain rivers: unraveling bionomy . Currently, it is widely recognized that invertebrates play key roles in neotropical floodplains and in many other environments worldwide. However, little information has been published concerning their biometry, in spite that it represents an essential tool for many different studies. Here, we provided length-mass and length-length relationships by fitting the linearized model (log 10 Y = log 10 a + b log 10 X) and several mean biomass ratios ± SE for bivalves, gastropods, quironomids, ephemeropterans, oligochaetes and hirudineans. We measured, weighed, oven dried and incinerated to ashes specimens collected from 2005 to 2014 in the Parana River, Argentina. The lineal equations had fit levels higher than 75% in most of the significant regressions. Hence, when slopes were compared, differences raised from ontogeny and phylogeny of taxa. Additionally, slopes resulted different from constants of other regions, types of environments and climates. In addition, significant differences were obtained in relation to feeding types of invertebrates when organic matter ratios were assessed. The equations and ratios that we provided will facilitate future research on life history, productivity and energy transference in the food webs of invertebrates inhabiting floodplain wetlands and can be used as tools for planning management strategies and in restoration projects of aquatic environments.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2017-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86062289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
