“…Predatory interactions play a crucial role in shaping the evolutionary trajectories and population dynamics of both predator and prey species (Menegucci et al, 2020). The interaction documented in this study is an example of the selective pressures that predators can exert on prey species during critical life events, such as reproduction.…”

Vocalization, visual and chemical signals are courtship behaviours of anurans that may expose them to the risk of predation. Here, we described a predation event in which a population of the torrent frog Hylodes cardosoi was in intense courtship behaviour and one individual was caught by a specimen of the pitviper Bothrops jararaca. The predation event was recorded in a region of Atlantic Forest, Paraná, Brazil. We hypothesized that the pitviper was ambush hunting and captured a female frog that was attracted by the vocalization of a nearby male. Predatory interactions are important ecological factors driving the evolution and population size of both prey and predator. This report increases the prey richness described for B. jararaca and also extends the known geographic distribution of H. cardosoi. Our observation contributes to knowledge of the natural history of the species involved.

“…The hypothesis of active predation must also be considered, as this behavior has already been observed for harvestmen when capturing invertebrates, such as coleopteran larvae in agricultural areas (Drummond et al 1990) and even vertebrates, as recorded by Menegucci et al (2020), in which the harvestman Heteromitobates discolor (Soerensen, 1884) (Opiliones: Gonyleptidae) preyed on an anuran of the species Hylodes phyllodes Heyer & Cocroft, 1986 (Anura: Hylodidae) in the Atlantic Forest. Finally, these arachnids can also be opportunistic, feeding on prey found dead, as observed by Halaj & Cady (2000) in agricultural cultivation.…”

Harvestmen are nocturnal arachnids, commonly found in humid forests, with omnivorous feeding behavior. There are records of different taxa in the diet of these arthropods, but data is still scarce for many species, especially in Cerrado areas. Thus, the objective of the present work is to report Lepidoptera and Hemiptera in the diet of the harvestman Acutisoma longipes Roewer, 1913, in Mata de Galeria in the Cerrado of Minas Gerais, Brazil. The records occurred randomly in the municipality of Luminárias, Minas Gerais, on October 10th and December 4th, 2023. In the first record, the species A. longipes was feeding on a moth (Lepidoptera: Erebidae). In the second record, the same species fed on a leafhopper, Mahanarva sp. (Hemiptera, Cercopidae). It was not possible to say whether these insects were preyed upon, usurped by other predators or found dead, but any of these hypotheses can be considered. This record contributes to increasing knowledge about the diet of harvestmen, especially in the Cerrado biome, where there is a need for more related studies.

“…Although less frequent, there are reports of anuran eggs and tadpoles as food items for some freshwater shrimp and crab species (Warkentin 1999, Warren et al 2021. Other arthropods can prey on juvenile forms of anurans, such as spiders (Nyffeler & Altig 2020), harvestmen (Menegucci et al 2020), and water bugs (González-Maya et al 2019). The predation risk for tropical anurans is higher during their activity peak, which for most tropical species occurs in the wet and warm season.…”

STOMACH MORPHOLOGY AND FIRST RECORD OF THE FRESHWATER SHRIMP Macrobrachium potiuna PREYING ON JUVENILE TREEFROG IN THE ATLANTIC FOREST

We present the first report of Macrobrachium potiuna (Arthropoda: Decapoda) preying on an juvenile anuran, alongside with a description of the stomach morphology of the shrimp individual. The freshwater shrimp was observed feeding on a juvenile hylid in the Atlantic Forest. We interpret the shrimp's behavior as opportunistic predation instead of necrophagy due to the small size of the treefrog and the absence of decomposition. We also briefly discuss some ecological theories that might be used to explain this trophic relationship. Shrimp dissection revealed no gastric mill or other maceration structures, but the stomach contents included dendrites and tissues of the prey, as well as two insect eggs from the order Diptera. Our findings contribute to the limited knowledge on the diet, anatomy, and trophic relationships of freshwater shrimps.
