“…Thus, in addition to transporting seeds away from the mother plant, seed dispersers can be important to the successful germination of some species by removing compounds that inhibit germination (Robertson et al 2006;Silveira et al 2012;Lessa et al 2013). Birds and ants are important groups that mutually interact as seed dispersers and can remove inhibitors, thus promoting germination (Meyer & Witmer 1998;Christianini & Oliveira 2010;Guerta et al 2011;Lima et al 2013), however, this influence is not uniform among zoochorous species (Barnea et al 1991;Figueroa & Castro 2002).…”

In natural conditions biotic and abiotic factors interact, synergistically affecting seed germination. In this study, we experimentally simulated natural conditions that occur during seed dispersal that can affect the germination of Copaifera langsdorffii. Specifically we evaluated the effect of aril removal by different dispersal agents (birds and ants) and fire on germination. The seeds were submitted to the following treatments: Control (seeds placed to germinate with aril intact); Acid (simulation of passage through the digestive tract of a bird); Aril removal (simulation of aril removed by ants); Fire (seeds exposed to fire). Germination percentage and time varied among treatments (X²=89. 735, P<0.001; X²=16.225, P<0.001, respectively). None of the control seeds (intact aril) germinated. Treatments that simulated dispersal (Acid, Aril removal) did not differ in germination percentage, with about 50% of the seeds germinating, however, the acid treatment accelerated seed germination. Fire also had a positive effect on seed germination with about 80% of the seeds germinating. Our results demonstrate the importance of dispersal agents to the population dynamics of C. langsdorffii. Furthermore, the capacity of seeds of C. langsdorffii to tolerate high temperatures is an important attribute for the occurrence of this species in the Cerrado.

“…Castiglioni et al (1995), comparando a germinação de sementes de M. parvifolia recolhidas das fezes de aves da espécie Ramphocelus bresilius L. (Emberizidae) com sementes coletadas diretamente de plantas matrizes, não obtiveram sementes germinadas para ambas as situações. Guerta et al (2011) avaliaram a germinação de sementes de Myrsine umbellata Mart.e Myrsine lancifolia Mart. após a passagem pelo trato digestório de diferentes espécies de aves (24 espécies para M. umbellata e 12 espécies para M. lancifolia), comparando-as com sementes não ingeridas por aves, não encontrando diferença significativa entre os tratamentos.…”

RESUMO-Myrsine coriacea (Sw.) R. Br. ex Roem. & Schult. é uma espécie arbórea nucleadora e alvo de intensa frugivoria, contribuindo para deposição de sementes de outras espécies. Devido suas sementes permanecerem no banco de sementes do solo, favorece a regeneração florestal após distúrbios naturais ou antrópicos. Com o objetivo de testar diferentes métodos para superação da dormência das sementes, foram analisados os seguintes tratamentos: Controle (TC), Escarificação Química (TQ), Escarificação Mecânica (TM) e Escarificação Térmica (TT). Foram avaliados os parâmetros: Percentual de Germinação (PG %), Índice de Velocidade de Germinação (IVG) e Tempo Médio de Germinação (TMG/dias). Para todos os parâmetros, o TM foi o mais eficaz para promoção da germinação, pois elevou a porcentagem e a velocidade de germinação, observando-se maior número de sementes germinadas em menor espaço de tempo. O TQ adotado foi deletério, e por isso não é recomendado. Não houve diferença significativa entre TC e TT. Palavras chave: escarificação, restauração ecológica, sementes florestais ABSTRACT-Seed germination of Myrsine coriacea (Primulaceae) submitted to different dormancy breaking treatments. Myrsine coriacea (Sw.) R.Br. ex Roem. & Schult. is a tree species with nucleation characteristics and a target to frugivorous animals, which contributes to the seed deposition to other plants. M. coriacea seeds remain in the soil for long periods, regenerating the forest after natural and anthropogenic disturbances. Four different methods were analysed with the aim to verify different types of breaking seed dormancy: Control (TC); Chemical Scarification (TQ); Mechanical Scarification (TM); Thermal Scarification (TT). The following parameters were evaluated, percentage of germination (PG) (%), germination speed index (IVG), and mean time of germination (TMG) (days). For all the parameters, we found that TM was more efficient at promoting germination, because it increased the percentage and speed of germination, which was observed with more seeds germinating in a short period of time. Meanwhile no difference was noticed between TC and TT, and the TQ was deleterious and is not recommended to break seed dormancy.

“…Dentro do gênero Myrsine os trabalhos registram valores de riqueza variáveis, como as 11 espécies de aves registradas se alimentando de Myrsine lancifolia (Martius) (Francisco & Galetti, 2001). Para M. umbellata e M. lancifolia foram registradas 24 e 12 espécie respectivamente (Guerta et al, 2011). Especificamente para Myrsine coriacea os trabalhos de Pineschi (1990) e de Jesus & Monteiro-Filho (2007) registraram 11 e 22 espécies de aves respectivamente.…”

Frugivory by birds Myrsine coriacea ((Sw.) R.Br. ex Roem. & Schult.) (Primulaceae) and their potential use in restoration projects Frugivory and seed dispersal studies are fundamental to comprehend the reproductive biology of plants. The aim of this work was to identify the species of birds that interact with M. coriacea, identifying its potentials dispersal vectors and assessing the use of this plant on ecological restoration programs. The observations were conducted on forest edges at Serra do Itajaí National Park, in two different moments with complementary methodologies. In the first period between June 2001 and 2002 it was adopted the hour-plant (tree-focal) as observation unit, with 15 plants selected for quantitative records, distributed throughout the day and totalizing 21 hours of observation. In the second period, from January 2013 to August 2015, it was adopted the feeding-bouts method on existing tracks. Considering both methods, 31 bird species were registered. Among them stand out in the focal method the species Turdus rufiventris (Vieillot, 1818), T. amaurochalinus (Cabanis, 1850) e T. abicollis (Vieillot, 1818), which in short visits ingested entire fruits, just as Tangara desmaresti (Vieillot, 1819) and Chiroxiphia caudata(Shaw & Nodder, 1793), forest species that promote the flow of seeds from more advanced stages of succession to areas under restoration. These aspects, associated with an abundant fructification and a fast shadowing, authorize their employment on ecological restoration projects.
