| spatial dynamics of understorey insectivorous birds and arthropods in a southeastern brazilian atlantic woodlot. | spatial distribution and spatial relationships in capture rates of understorey insectivorous birds and density of arthropods were investigated in a patch of upper montane rain forest in minas gerais state, southeastern brazil, from january to december 2004. the composition of the arthropod fauna collected was similar to that reported for other tropical forests, with predominance of araneae, coleoptera, hymenoptera and hemiptera non-heteroptera. a total of 26 bird species were captured, among whi ... | 2011 | 21437393 |
| two new species of the feather mite genus analloptes (trouessart, 1885) acariformes: astigmata: xolalgidae) from passerines (aves: passeriformes) in brazil. | two new feather mite species of the genus analloptes trouessart, 1885 (acariformes: xolalgidae) are described from suboscine passerines (passeriformes) in brazil: analloptes giganteus sp. n. from conopophaga lineata (wied) (conopophagidae) and a. cnemotricci sp. n. from cnemotriccus fuscatus (wied) (tyrannidae). these are the first analloptes species described from passerine hosts. within the genus analloptes, the two described species constitute a distinct species group characterized by the pre ... | 2014 | 25544285 |
| feeding resource partitioning between two understorey insectivorous birds in a fragment of neotropical cloud forest. | the food habits and niche overlap based on diet composition and prey size of two species of understorey insectivorous birds were investigated in an area of montane rain forest in the state of minas gerais, southeastern brazil. a total of 43 birds were captured: 33 individuals of conopophaga lineata (conopophagidae) with 13 recaptures, and 10 individuals of myiothlypis leucoblephara (parulidae) with 12 recaptures, from which were obtained respectively 33 and 10 fecal samples. fragments of 16 grou ... | 2015 | 26602358 |
| genetic variability of conopophaga lineata (conopophagidae) (wied-neuwied, 1831) in atlantic forest fragments. | forest fragmentation affects bird populations in many ways, modifying the composition of communities and favouring open country species. the atlantic forest is considered one of the most important biomes in the world, due to its great biodiversity, accelerated rates of deforestation, and high endemism. despite these characteristics, few studies have evaluated the effects of forest fragmentation in the genetic structure of atlantic forest bird populations. so, this study aims to verify the effect ... | 2007 | 18278352 |
| isospora borbai n. sp. (chromista: apicomplexa: eimeriidae) from gnateaters conopophaga spp. (passeriformes: tyranni: conopophagidae) in south america. | the gnateaters conopophaga spp. are insectivorous passerines commonly observed in high and humid forests, where they remain lodged in thin branches and, sometimes, they fly to the ground to catch insects. the insectivorous feeding habit is related to low prevalence and density of coccidians in passerines; however, several coccidian species are recorded for families of insectivorous passerines. | 2019 | 31187387 |
| the molecular cytogenetic characterization of conopophaga lineata indicates a common chromosome rearrangement in the parvorder furnariida (aves, passeriformes). | cytogenetic analyses of the suboscines species are still scarce, and so far, there is no karyotype description of any species belonging to the family conopophagidae. thus, the aim of this study is to describe and analyze the karyotype of conopophaga lineata by chromosome painting using gallus gallus (gga) probes and to identify the location of the 18/28s rdna cluster. metaphases were obtained from fibroblast culture from two individuals of c. lineata. we observed a diploid number of 2n=78. gga p ... | 2020 | 32542304 |
