Sapajus Apella

The Neotropical primate Sapajus apella (Linnaeus, 1758), the black-capped capuchin monkey, is widely distributed across the Amazon basin (Boubli et al., 2020). Capuchins are generalist platyrrhines, occurring in most tropical forest types, where they forage opportunistically (Sabbatini et al., 2008; Lynch Alfaro et al., 2012; Boubli et al., 2020). They exploit a diverse variety of food sources, such as fruit, seeds, arthropods and vertebrate prey including small mammals (Rose, 1997; Resende et al., 2003; Albuquerque et al., 2014). Their foraging strategy is highly resourceful and adaptive, and are often considered as important predators of nests (Canale and Bernardo, 2016), including those of caiman (Torralvo et al., 2017), coatis (Rose, 1997) and especially of birds (Watts, 2020). In this work, we report observations of a foraging event by Sapajus apella that includes the first record of egg predation of the russet-backed oropendola, Psarocolius angustifrons (von Spix, 1824), as well as the predation of arboreal rodents, Oecomys sp. (Thomas, 1906).

Immature stages of many Brazilian Smicridea species remains unknown, and efforts to describe all life stages are required. In this paper, the larva and pupa of Smicridea (Rhyacophylax) gladiator Flint 1978, associated with adults through the metamorphotype method, are described and illustrated. In addition, the known distribution of this species is extended in the Brazilian Amazon Basin with new records from Amazonas state and the first record in Pará state. Information about its bionomics is also provided.

The orchid-bee faunas of ‘Parque Nacional do Monte Pascoal’, ‘Parque Nacional do Descobrimento’ and three other Atlantic Forest remnants ranging from 1 to 300 ha in southern Bahia, eastern Brazil, were surveyed. Baits with seventeen different scents were used to attract orchid-bee males. Four thousand seven hundred and sixty-four males belonging to 36 species were actively collected with insect nets during 300 hours from November, 2008 to November, 2009. Richness and diversity of orchid bees found in this study are the highest ever recorded in the Atlantic Forest domain. Eufriesea dentilabris (Mocsáry, 1897) and Eufriesea violacea (Blanchard, 1840) were collected at the ‘Parque Nacional do Monte Pascoal’, the first record of these species for the state of Bahia and the northernmost record for both species. Females Exaerete dentata (Linnaeus, 1758) were also collected at ‘Parque Nacional do Monte Pascoal’ and old records of Eufriesea aeneiventris (Mocsáry, 1896) in this area makes this site the richest and most diverse concerning its orchid-bee fauna in the entire Atlantic Forest and similar to areas in the Amazon Basin.

Behavioral Aspect

Abstract Like for many species, the timing of evening emergence of bats is an important behavioral aspect that affects their fitness and has been studied in various bat species. However, little is known about emergence timing of solitary bats that frequently switch day roosts, because they are difficult to observe. In this study, I examined the emergence timing of Hilgendorf’s tube-nosed bats (Murina hilgendorfi), which are solitary and frequently switch roosts, in relation to roost type and season over six years in Hayakawa, central Japan. The results show that the bats emerged after dusk when the light was weak. Later emergence may be related to the habits of this species, such as their solitary lifestyle, slow flight speed, and gleaning foraging strategy, which may enhance predation risk. Individuals roosting in dead foliage and on the outer wall of a building situated in closed forests emerged significantly earlier than those roosting in an old mine and tunnel located in open environments, suggesting that vegetation cover and/or lower predictability of roost location provide security for bats. Bats emerged progressively earlier from late spring (preparturition) to early autumn (late lactation or post-lactation), suggesting that the reproductive status of females or the growth stage of pups may influence emergence timing. To my knowledge, this study provides the first record of the emergence timing of Hilgendorf’s tube-nosed bat, and suggests that predation risk may impact the bats’ emergence behavior.

As part of a review in progress on the genus Clusia Linnaeus in Venezuela, Clusia ucamira J.E. Nascim. & Bittrich is reported for the first time for that country. Clusia ucamira is quickly distinguished from similar species of Clusia sect. Oedematopus (Planchon & Triana) Pipoly by its hemiepiphitic habit, strongly coriaceous and conspicuously revolute leaves, with a very prominent midvein in the abaxial surface. With this range extension, Clusia ucamira is known, besides from the Amazon basin, from terra firme forest in the Amazonas state of Venezuela, where it grows in oligotrophic soils derived from materials from the Guayana Shield. In Venezuela, this species is to be considered Least Concerned (LC), according to the IUCN Red List categories.

In artificial-nest studies, Japanese Quail (Coturnix japonica) eggs have been used as surrogates for passerine eggs, although small mammals that prey on passerine eggs may be unable to consume Japanese Quail eggs. To determine the influence of egg size on nest predation in different landscapes on insular Newfoundland, we placed either a Japanese Quail egg or a smaller Chinese Painted Quail (Xexcalfactoris chinensis) egg in artificial ground nests along lakeshore forest edges and along riparian buffer strips. Clay eggs were used to identify nest predators. Levels of predation on nests with Japanese Quail and Chinese Painted Quail eggs were similar. Based on clay eggs, predation was attributed to red squirrels (Tamiasciurus hudsonicus), and we found no evidence that smaller mammals preyed on artificial nests. We conclude that the Japanese Quail egg is acceptable for use in artificial-nest studies in Newfoundland, and we discuss the implications of egg size and small mammals in nest-predation experiments.

Chrysopelea taprobanica Smith, 1943 was previously considered to be endemic to the dry and intermediate zones of Sri Lanka. However, an adult specimen of C. taprobanica was collected from Seshachalam Biosphere Reserve of Andhra Pradesh, India, being the first record of this snake species from India, significantly extending the known range of distribution of the species. The dry zones of peninsular India were connected with Sri Lanka as recently as ca. 17,000 years ago, which probably allowed movement of species between these two regions.

Predation Rates

Predation rates of nests at human-induced habitat edges may be greater than in forest interior due to differences in predator assemblages and predator activity. I compared the predation rates on 192 artificial nests containing plasticine eggs placed in forest edge and interior sites at Bunyip State Park, Victoria. The nest-predation rates at the forest edge sites were significantly greater (mean = 52–58%) than that at the forest interior sites (mean = 30–39%). The relative rates of predation by birds compared with mammals were significantly greater at forest edge sites (mean = 78–94%) than at forest interior sites (mean = 36–67%). Higher rates of nest predation at forest edges appeared to be due to greater densities of avian predators such as the grey shrike-thrush (Colluricincla harmonica), and/or lower abundances of small mammals. However, biases towards certain predator types may mask real, or create false, patterns in predation rates of artificial nests. A better understanding of how predators respond to artificial nests compared with natural nests is required. Until then, results of predation studies that use artificial nests should be interpreted with caution.
