“…The importance of zoochorous species needs to be highlighted, which is mainly linked to the enrichment of the region flora, increasing the presence of seed-dispersing animals (Reznik et al 2012, Colmanetti et al 2016. In degraded or recovering land, the planting of zoochorous species is particularly important due to the seed spread of forest species by wild animals when the forest is in an advanced stage of ecological succession (Sangsupan et al 2018).…”

The Vale do Ribeira region has a large extension of Brazilian Atlantic Forest, and in most cities, low environmental impact activities predominate, such as sand mining. Sand mining has been trying to adapt their industrial activities to low environmental impact, aiming at the protection of permanent preservation areas (PPAs) of riparian forests. The objective of this work was to conduct a case study focused on monitoring and initial growth of forest species by 18 months. This study was performed in a riparian forest site on the Ribeira de Iguape River, Registro, state of São Paulo, Brazil, in a PPA with extraction of river bed sand. Forest species height, stem diameter and mortality index, and rainfall were evaluated in the period. Non-pioneer species accounted for 42.7 % of the forest, while pioneer species accounted for 53.1 %. These proportions are in accordance with local legislation, which establishes a lower limit of 40 % in planting for both groups. Drought periods and leaf-cutting ants at the beginning of growth stages contributed to a higher mortality index and irregular development of some species, however, even during such adversities, forest species indicated resistance to these conditions. Pioneer species had more important development, with emphasis on Senna multijuga, Alchornea triplinervia, Citharexylum myrianthum and Trema micranta, these species must be taken into consideration during the first stages of a project which aims at recovering degraded areas in riparian forests of Atlantic Forest.

“…Our findings corroborate records from other studies in semideciduous forests in the Central Plateau of Brazil (MILHOMEM; ARAÚJO; VALE, 2013). There are records that zoochory is also dominant in natural regeneration in places under ecological restoration processes (COLMANETTI et al, 2016). In general, the occurrence of zoochoric species is important in natural ecosystems, since it increases the environmental complexity, with more interactions between animal and plant species.…”

Estudos comparativos entre diferentes estratos de florestas em sucessão ecológica são importantes para entender a dinâmica florestal. O estudo avaliou aspectos florísticos, fitossociológicos e ecológicos entre os estratos adulto e regenerante de um fragmento urbano de floresta estacional semidecidual, em Jataí, Goiás. Nas últimas décadas, a vegetação que era tipicamente savânica tem se tornado uma floresta. As árvores adultas (diâmetro a altura do peito, DAP ≥ 5 cm) foram amostradas em 12 parcelas permanentes de 200m². Em cada uma delas, sub-parcelas de 25m² foram amostradas para o estrato regenerante, que compreendeu indivíduos com DAP 5cm e altura ≥ 1m. Regenerantes tiveram maior riqueza (31 espécies), com duas espécies a mais do que os adultos. Houve baixa similaridade florística e estrutural entre os estratos, indicando uma substituição de espécies ao longo do tempo. A diversidade de Shannon foi significativamente menor para o estrato arbóreo (teste t), visto que apresentou baixa equabilidade, com dominância ecológica de poucas espécies. Ambos os estratos tiveram elevada proporção de espécies pioneiras, quando comparado com outros estudos. Zoocoria e espécies de ambientes florestais foram expressivamente mais abundantes no estrato regenerante. O estudo revelou um fragmento em franco processo de sucessão secundária e vulnerabilidade diante de pressões antrópicas, sendo importante os cuidados quanto à sua conservação.

“…It grows up to 18 m in height, with a diameter at breast height of approximately 60 cm, and 10 to 15 m crown diameter bearing long branches. The fruits are indehiscent legumes with an approximate size of 5.6 cm in length and 2 cm in diameter, and when ripe they are brownish to yellowish and contain approximately 14 seeds of 1.5 cm diameter enveloped in a white, sweetish aril [46,[58][59][60]. The fruits and the seeds are mainly consumed by primate seed dispersers [53], but are also unequivocally a source of food for many different species of birds, e.g., five species of parrots (seed predators [61]) and several species of Passeriformes (seed dispersers [62]) and bats (seed dispersers [63]).…”

Seed removal is a key component of seed dispersal and may be influenced by both landscape-scale and local attributes, and it has been used as an indicator of the intensity of interactions between ecosystem components. We examined how the seed removal rates, which integrate the activity of seed dispersers and seed predators, vary with landscape-scale forest cover. We collected data under 34 trees belonging to two zoochoric species (Helicostylis tomentosa (Poepp. and Endl.) J. F. Macbr. and Inga vera Willd.) in 17 remnants in the Brazilian Atlantic forest, with different percentages of forest cover. The seed removal rate was estimated using a fast method based on the abundance of intact fruits and fruit scraps on the ground. The amount of forest cover affected the rate of seed removal in a humpbacked shape, with a maximum seed removal rate at intermediate forest cover. Seed removal rates must be related to the amount of food resources offered and diversity of dispersers and predators in the region. In landscapes with intermediate forest amount, there is a better balance between supply and demand for fruits, leading to a higher seed removal rate than more deforested or forested landscape. Our results also show that local factors, such as crop size and canopy surface, together with forest cover amount, are also important to the removal rate, depending on the species. In addition, our results showed that plant–animal interactions are occurring in all fragments, but the health status of these forests is similar to disturbed forests, even in sites immersed in forested landscapes.
