“…These eggs were found in faeces of coscoroba swan among some intact shells and uncountable fragments of snails (Hydrobiidae and Planorbidae). Temnocephalida species are ectosymbionts of snails and other aquatic organisms (Amato and Amato, 2005;Seixas et al, 2010), and the presence of these eggs in the samples may be due to accidental ingestion, when birds were feeding on snails. We did not find previous references of Temnocephalida eggs dispersed by endozoochory, thus the viability of these…”

Invertebrate dispersal by waterbird species in neotropical wetlands

et al. 2024

Endozoochory by waterbirds is particularly relevant to the dispersal of non-flying aquatic invertebrates. This ecological function exercised by birds has been demonstrated in different biogeographical regions, but there are no studies for the neotropical region. In this work, we identified propagules of invertebrates in faeces of 14 syntopic South American waterbird species representing six families, and hatched additional invertebrates from cultured faeces. We tested whether propagule abundance, species richness and composition varied among bird species, and between the cold and warm seasons. We found 164 invertebrate propagules in faecal samples from seven different waterbirds species, including eggs of the Temnocephalida and Notonectidae, statoblasts of bryozoans (Plumatella sp.) and ephippia of Cladocera. Ciliates (including Paramecium sp. and Litostomatea), nematodes and rotifers (Adineta sp. and Nottomatidae) hatched from cultured samples. Potential for endozoochory was confirmed for 12 of 14 waterbird species. Our statistical models suggest that richness and abundance of propagules are associated with bird species and not affected by seasonality. Dispersal by endozoochory is potentially important to a broad variety of invertebrates, being promoted by waterbirds with different ecological and morphological traits, which are likely to drive the dispersal of invertebrates in neotropical wetlands.

Los aeglídeos son crustáceos dulceacuícolas, siendo importantes en la cadena trófica para diversos organismos invertebrados y vertebrados. Un espécimen de Aegla spinosa Blond-Buckup & Buckup, 1994, proveniente del interior del município de Bocaina do Sul, estado de Santa Catarina, fue llevado al Laboratorio de Parasitología y Zoología de la Universidad del Planalto Catarinense (UNIPLAC). El crustáceo examinado presentó tres especímenes de Temnocephala. Dado que se trata de animales vulnerables a las alteraciones ambientales y los cambios en el paisaje natural debido a la presión antrópica, conocer la presencia de temnocefálidos puede contribuir al conocimiento de las asociaciones entre estos organismos y sus hospederos, especialmente en el estado de Santa Catarina, donde existe una falta de descripciones para la fauna de invertebrados.

Microturbellarians (Platyhelminthes and Acoelomorpha) in Brazil: invisible organisms?

2016

Microturbellarians typically belong to the benthos and may occur in a wide variety of environments. They are abundant in freshwater and marine ecosystems and may occur in moist terrestrial habitats. However, turbellarians are seldom taken into account in studies of biodiversity. Most studies on Brazilian microturbellarians had taxonomical purposes and were done in the years 1940-1950. Thus, information on their occurrence and ecological aspects are dispersed throughout several papers. We intend here to summarize the biogeographical distribution and ecological aspects of microturbellarians recorded for Brazil, indicating the main gaps in their knowledge and possible actions to enhance studies on this group. There are 239 species of microturbellarians registered for Brazil, with records distributed in 12 states. However, just three states located in southern Brazil have records of 94% of microturbellarian species. Thus, knowledge on the systematics and geographical distribution of Brazilian microturbellarians clearly reflect the scientific activity over many years or decades in two states of southeastern and southern Brazil. Considering the scant information on this group in Brazil, which is also the situation of the Neotropical microturbellarians in general, some actions should be proposed. First, it would be necessary to sample in the diverse biomes, as well as in the various river and sea basins, based on standardized sampling protocols. Second, it would be necessary to encourage diverse research groups to include microturbellarians and/or turbellarians in general into biodiversity inventories and studies on community structure of invertebrates. Third, it is necessary to increase the number of research groups on microturbellarians, in order to augment the studies on their morphology, systematics, and ecology. Considering their abundance, species richness and ecological importance in aquatic environments, despite some peculiarities regarding their sampling, sorting and identification procedures, the challenge to study microturbellarians and enhance knowledge about them in Brazilian ecosystems should be faced.Keywords: Platyhelminthes, species diversity, Neotropical region, systematics, ecology.
