“…Dung beetles are often common, especially in Neotropical forests, where a high number of sympatric species compete intensively for ephemeral resources (Hanski & Cambefort 1991, Herrera et al 2002, Larsen et al 2006. The majority of Neotropical dung beetles opportunistically forage in the understory for mammal dung, though mammal dung in Neotropical forests is limited because there are relatively few large vertebrates (Larsen per.…”

“…In response to intense competition for limited resources, many species of dung beetles have evolved specialized niches or behaviors for obtaining food (Larsen et al 2006), including positioning themselves at the source of vertebrate dung. Phoretic behavior of dung beetles on mammals has been described for various genera of dung beetles in different regions of the world.…”

Neotropical Entomology 37(6): 641-645 (2008) El Primero que Llegue, Primero se Sirve: Comportamiento "Sentarse y Esperar" en los Escarabajos del Estiércol en la Fuente de Excremento de Primate RESUMEN -Los Escarabajos del estiércol (Coleoptera: Scarabaeidae: Scarabaeinae) compiten intensamente por excrementos, un recurso escaso por el cual muchas especies forrajean en el sotobosque en bosques tropicales. En este artículo describimos el comportamiento particular de una especie de escarabajo del estiércol, Canthon aff. quadriguttatus (Olivier), asociado a dos especies de primates en Perú. Observamos esta especie de escarabajo en la región genital y anal de monos "tocones", Callicebus brunneus (Wagner), y subsecuentemente cayendo con excrementos que los monos defecaron. De manera similar, observamos individuos de esta especie de escarabajo asociados a monos "huapos", Pithecia irrorata irrorata (Gray). Mediante un comportamiento de "sentarse y esperar" a la fuente, C. aff. quadriguttatus llega primero a la fuente de excremento y aparentemente supera a otras especies de escarabajos en la competencia por el mismo recurso. Este artículo representa el primer registro de C. aff. quadriguttatus en asociación a dos especies de primate en la Amazonía del sureste de Perú. Discutimos este comportamiento en el contexto de competencia y distribución de recursos y especulamos sobre la razón por la cual este escarabajo está asociado a ambas especies de primates. PALABRAS-CLAVE: Competencia, distribución de recursos, foresia, especialización de nichoABSTRACT -Dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) compete intensively for dung resources, and most species forage in the understory. Here, we describe the unique behavior of one dung beetle species, Canthon aff. quadriguttatus (Olivier), associated with two species of monkeys from Peru. We observed this beetle species on the genital and anal regions of the brown titi monkey, Callicebus brunneus (Wagner), and subsequently falling with dung as the monkeys defecated. The same association was also observed with the bald-faced saki monkey, Pithecia irrorata irrorata (Gray).Using the "sit and wait" at the source behavior, C. quadriguttus may arrive fi rst at the dung resource, possibly out-competing other dung beetle species. This paper is the fi rst report of this behavior for C. aff. quadriguttatus on the brown titi monkey and bald-faced saki monkey from southeastern, Amazonian Peru. We discuss this behavior in the context of competition and resource partitioning, and also speculate as to why C. aff. quadriguttatus has been found on both monkey species.

“…Contudo, a maior riqueza observada em armadilhas de queda iscadas com fezes humanas se deve ao fato de que Scarabaeinae, devido a processos evolutivos, possui maior número de espécies coprófagas que utilizam excrementos de mamíferos como alimento de adultos e larvas (Halffter & Matthews 1966, Hanski & Cambefort 1991. Na região Neotropical, excremento humano é um dos mais importantes atrativos para a efetiva captura das espécies de Scarabaeinae, tanto em florestas quanto em pastagens (Halffter & Matthews 1966, Falqueto et al 2005, Larsen et al 2006, Filgueiras et al 2009). …”

This work presents a survey of Scarabaeinae species from a natural grassland area in Bagé, state of Rio Grande do Sul, Brazil. Samplings were carried out with flight intercept traps and pitfall traps baited with human feces, rotten banana and rotten meat, from December 2005 to November 2006. A total of 4,573 individuals, belonging to 14 genera and 30 species were collected. Onthophagus aff. hirculus Mannerheim, 1829, Canthon podagricus Harold, 1868, Ontherus sulcator (Fabricius, 1775) and Canthidium moestum Harold, 1867 were the most abundant species. Most of the captured assemblage is composed by species coprophagous and generalists preferably necrophagous. Few species were strictly necrophagous and none was classified as saprophagous. The rollers and tunnelers were represented by similar numbers of species.

“…For the lowlands (300-500 m), we use forest types that are widely recognized by plant and animal ecologists working in western Amazonia (Pitman et al 1999, Larsen et al 2006, Griscom et al 2007. One of these forest types, the floodplain, can be classified in two general categories: mature floodplain forest and early successional floodplain forest.…”

Abstract:We compile a list of all amphibians and reptiles known to occur within Manu National Park, Peru and its buffer zone, located in one of the world's biodiversity hotspots. Covering approximately 0.01% of the planet's terrestrial surface, this protected area preserves 155 species of amphibians and 132 species of reptiles, corresponding to 2.2% and 1.5% respectively of the known diversity for these groups. Moreover, Manu National Park preserves natural habitats and populations of one critically endangered (Atelopus erythropus), three endangered (Bryophryne cophites, Pristimantis cosnipatae and Psychrophrynella usurpator), three vulnerable amphibians (Atelopus tricolor, Gastrotheca excubitor, Rhinella manu) and two vulnerable reptiles (Chelonoidis denticulata, Podocnemis unifilis), according to the threat categories of the IUCN Red List.
