“…Seed dispersal is an important mechanism for many plant species because it allows for the transport of offspring to areas distant from the parent plant, contributing to a decreased competition for resources, reduced density-dependent seedling mortality, and increased ability to finding suitable microhabitats for the establishment and colonization of new areas (Howe & Smallwood 1982, Hämäläinen et al 2017, Souza et al 2021. Zoochory (dispersal by animals) is the main form of seed dispersal in tropical forests, and birds and mammals are the main dispersing agents (Bascompte & Jordano 2013).…”

Zoochory is a fundamental process that can be the main mechanism for seed and plant dispersal for many species. Mammals of the Carnivora order are among the most important dispersing agents; however, little is known regarding the role of canids as seed dispersers. Although the maned wolf (Chrysocyon brachyurus) has a potentially important role in seed dispersal, given its relatively high consumption of fruits, few studies have investigated the germination rate of ingested seeds. Here, we used seeds removed from the feces of two captive specimens (maned wolf treatment) and those directly collected from unconsumed fruits (control) in germination essays to evaluate the germination rate and emergence velocity index (IVE). We used mature fruits from five species of trees in the Cerrado and Atlantic Forest in a 5 (species) × 2 (method of seed collection) factorial arrangement. The passage of seeds through the digestive tract of the maned wolf favored the germination of Genipa americana and Psidium guajava, delayed germination of Psidium cattleianum, and maintained the germination of Plinia cauliflora and Ficus obtusifolia. Our results revealed that germination occurred for all tested plant species consumed by the maned wolf; therefore, this canid species has high dispersal potential and can be an important ally in the restoration of the Cerrado and Atlantic Forest-Cerrado contact zone ecosystems.

“…It has a generalist and opportunistic diet, feeding on fruits, insects, crustaceans, and small vertebrates (Gatti et al 2006;Rocha et al 2008;Beisiegel et al 2013). Studies reveal the importance of this species in maintaining essential ecological functions, such as frugivory and seed dispersal (Goebel et al 2023;Souza et al 2021). However, much of the information available on the feeding ecology of C. thous is known from fecal analysis (Rocha et al 2004;Raíces & Bergallo 2010;Rocha-Mendes et al 2010), limiting information on behavior in events of predation.…”

The crab-eating fox (Cerdocyon thous) is a Neotropical canid with a generalist and opportunistic diet that includes a wide variety of food items. On this note, we report the first record of predation on Rhinella marina by Cerdocyon thous in the state of Rondonia, Brazil, based on camera trap footage. For the state of Rondonia, there is no study reporting the prey of C. thous. Therefore, this report approaches important ecological knowledge of the crab-eating fox, portraying behaviors and diet of the species.
