“…Uma espécie foi considerada de dieta especializada quando um tipo de presa representou 75% ou mais do total de presas registradas (Martins et al 2001). O comprimento rostro-cloacal do menor macho maduro e da menor fêmea madura de cada espécie serviu para diferenciar indivíduos adultos de imaturos (Shine 1977, Marques 1996, Hartmann & Marques 2005.…”

Ecology and natural history of a snake assemblage at Núcleo Santa Virgínia, Parque Estadual da Serra do Mar, southeastern Brazil. Biota Neotrop., 9(3): http:// www.biotaneotropica.org.br/v9n3/en/abstract?article+bn03609032009. Abstract:The objective of this study was to describe the natural history and the ecology of a snake assemblage in the Atlantic rainforest, at Núcleo Santa Virgínia, Parque Estadual da Serra do Mar, located on the northeastem of the state of São Paulo, southeastern Brazil. We describe richness, relative abundance, daily and seasonal activity, and substrate use, besides additional aspects of the natural history of the snakes. A total of 148 individuals, of 27 species, 19 genera and four families, were found within the area of the Núcleo Santa Virgínia. Species that were sampled more frequently were Bothrops jararaca, Xenodon neuwiedii and Liophis atraventer. Among the abiotic factors analyzed, minimum temperature, followed by mean temperature and rainfall are apparently the most important in determining snake abundance and/or activity. Most species presented a diet concentrated on one prey category or restricted to a few major food items. Frogs seem to be the most important food resource for snake assemblages in the Atlantic rainforest on the top of Serra do Mar. Our results indicate that the structure of the Núcleo Santa Virgínia snake assemblage reflects mainly the ecological characteristics of each of the lineages that compose the assemblage.

“…(i) Brightly banded neotropical snakes are mimics of elapid coral species. In spite of a previous debate, coral snake mimicry is widely supported by studies of geographic concordance (Greene & McDiarmid 1981, Marques & Puorto 1991, Harper & Pfennig 2007, allopatric mimicry (Pfennig et al 2001, Pfennig & Mullen 2010, Akcali & Pfennig 2014, and genetics and evolution (Harper & Pfennig 2008, Pyron & Burbrink 2009, Kikuchi & Pfennig 2010, Pfennig et al 2015. (ii) A wide range of mimics of poisonous species are protected from predation.…”

Selective advantage conferred by resemblance of aposematic mimics to venomous model

Mimicry is an excellent example of how natural selection can act on color, morphology, and behavior of species. Herein we assess predation rates on coral snake mimics in Central Brazil, a region with many mimics but only a single model, to answer the following questions: (i) Do predators avoid attacking coral snake mimics? (ii) Does the degree to which mimics resemble their venomous model affect the frequency of predator attacks? (iii) Do predators attack different body regions in mimics with different color patterns? Our experiment was conducted in the Chapada dos Veadeiros National Park, in the municipality of Alto Paraíso de Goiás, state of Goiás, Brazil. To evaluate predation rates on the different mimic patterns, we made 2,400 clay snake replicas using pre-colored nontoxic plasticine and distributed them in open savanna landscapes within the park. A total of 164 (6.83%) replicas were attacked by predators of snakes. Among these attacks, 121 were attacks by birds, and 43 were attacks by carnivorous mammals. Logistic regression and Fisher’s exact test indicated that replicas with red, white, and black coloration are less likely to be attacked than were grey replicas, and coral snake replicas were attacked more often at the “head” end. Also, the greater the similarity to the pattern of venomous coral snakes, the rarer the attack on the replica. Our study underscores the strong selective force that protects coral snake mimics from predators. Our findings reinforce resemblance to the model as an extremely effective strategy in a complex natural system with only one model and numerous mimics.

“…In general, mimicry in snakes involves either morphology, behavior, or both of the latter (Green 1973, Green and McDiarmid 1981, Marques and Puorto 1991. Some species of Dipsadini demonstrate strong patterns of mimicry with sympatric pitvipers (Sazima 1992, Martins andOliveira 1998).…”
