We analyzed the impact of the invasive white ginger lily ( Hedychium coronarium Konig J, 1783.– Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ginger monotypic bank, forest partially invaded, native macrophyte monotypic bank and riparian forest. At each vegetal bank, we measured abiotic variables such as dissolved oxygen, pH, water temperature and depth. We analyzed the aquatic insects through abundance, richness and Simpson diversity. We used the non-Metric Multidimensional Scaling (nMDS) analysis to analyze the spatial distribution of each assemblage, and Analysis of similarities (ANOSIM) to verify differences amongst dissimilarity distances. Additionally, we analyzed the main taxa associated with invasive macrophytes through indicator species analyses using IndVal index. We observed that the invasive macrophyte banks presented higher abundance of associated specimens, as well as lower dissimilarity of aquatic insect assemblages. Additionally, invasive macrophytes shifted the water pH and littoral depth of reservoir banks. The IndVal index indicated eight aquatic insects as indicator species. Labrundinia unicolor Silva, 2013 , Ablabesmyia depaulai Neubern, 2013 and Diastatops Rambur, 1842 were indicator species on banks. We concluded that invasion of white ginger lily caused loss of shallow littoral habitat and altered the pH of the surrounding water probably by high decomposition rate and high production of plant biomass. We suggest the use of species of aquatic insects as indicator species to monitor white ginger lily impact in freshwater systems.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":"43 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2017-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87016671","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 total of 50 Myrmecophaga tridactyla and 178 of Tamandua tetradactyla skulls were analyzed in relation to 18 skull dimensions. The skulls were grouped into three level of suture closure: none suture closured (level 0), many sutures closured (level 1) and all the sutures closured (level 2). The results indicated that among the 18 variables measured, 17 showed significant differences (p ≤ 0.01) between immature and sub-adults skulls of T. tetradactyla ; as well as between immature and sub-adult, besides immature and adult skulls of M. tridactyla . Myrmecophaga tridactyla sub-adults and adults had no significant difference among any of the 18 dimensions. The foramen magnum height in both species showed no significant difference (p > 0.05) among any of sutures categories. In principle, suture closure level and cranial dimensions are important to estimate age group for both species of anteaters, and both T. tetradactyla and M. tridactyla immature individuals have the foramen magnum height similar to adult animals.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":"23 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2017-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88614427","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}

Considerando Lontra longicaudis (Olfers, 1818) informacoes publicadas nao foram encontradas. Entao, o presente estudo objetivou determinar se os deslizamentos de terra ocorridos em marco de 2011 em parte das montanhas da Serra da Prata (Parana, Brasil) afetaram de alguma forma a ocorrencia da Lontra Neotropical. Com esse proposito, a area estudada compreendeu um rio afetado (Rio Santa Cruz - RSC) da face leste dessa serra que foi comparado com outro nao afetado (Rio das Pombas - RP), localizado na mesma face e com caracteristicas semelhantes as originais do RSC. A area de estudo esta situada no parque nacional de Saint-Hilaire/Lange (PNSHL). Foram realizadas sete campanhas a partir do limite altitudinal do PNSHL (60 m s.n.m) para montante entre 2012 e 2013. As campanhas consistiram de busca ativa por vestigios (fezes, pegadas, arranhados) e tocas de lontras ao longo de 3 km de margens. Registros de outros mamiferos tambem foram observados. Cada evidencia foi anotada em caderneta de campo, fotografada e georreferenciada. As tocas foram monitoradas ao longo das campanhas. Considerando as lontras, foram registrados 113 vestigios (11 arranhados, 19 pegadas e 83 fezes) e 17 tocas no rio nao afetado (RP); e o rio afetado (RSC) apresentou apenas quatro vestigios (tres pegadas, uma amostra fecal) e uma toca. Registros de outros mamiferos denotaram a presenca de 9 taxons no RP e 14 taxons no RSC. As diferencas conspicuas entre a quantidade de vestigios da presenca das lontras mostram que o desastre natural afetou severamente a populacao de lontras do RSC e mesmo dois anos apos os desastres as lontras retornaram apenas discretamente ao rio afetado. Por outro lado, outras especies de mamiferos como Cuniculus paca (Linnaeus, 1758), reocuparam as margens abundantemente.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":"76 1","pages":"1-8"},"PeriodicalIF":0.4,"publicationDate":"2017-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80539833","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}
