In spite of the the Covid-19 pandemic, forest restoration is proceeding at REGUA observing all the necessary measures to safeguard the staff´s health. Already 18 hectares have been planted within the “Armenio” land in the vicinity of Matumbo village.
Thirty thousand seedlings of 113 Atlantic Forest different tree species were planted since February this year. Aside this, the maintenance of the 60 hectares planted in 2017-2019 has also been completed and we are now in the process of planting five hectares belonging to REGUA´s partners as part of the Petrobras socio-environmental Guapiaçu III project. Brazilian Forest Code obliges land owners to restore hillsides with slopes over 45º, hill tops, water springs and riparian vegetation alongside rivers and streams. REGUA is making this available for partners who share the same conservation vision within the Guapiaçu watershed.
The Environment Week (01/06 to 05/06 2020) began with the viewing of the “Grande Vida” trail from home. The narrated tour begins on the Yellow trail and reaches the wooden bridge in which the viewer is accompanied by the sounds of nature, specially of birds that often can be seen and heard at REGUA’s wetlands. It is possible to select icons such as photos and self-explanatory posters that are present along the trail showing the Atlantic Forest biodiversity, animal tracks, view of the wetlands, forest dynamics and some of the conservation work carried out at REGUA.
The idea is quite innovative, even though there are already some virtual visits in National Parks across the country. What makes it different is the fact that it was made in a Private Nature Reserve (RPPN). It is worth mentioning that home office has changed the routine of many professionals worldwide, however this is far from preventing people’s contact with nature. Thus, it is essential to share contents with technological tools, as well as to keep up with digital media trends. The Environment Week was also featured with several live sessions broadcasted on Instagram, covering topics related to other projects financed by Petrobras that are part of Guanabara Bay network. All of these initiatives are a means to bring a little inspiration to those in quarantine respecting social isolation.
The Yellow Rat Snake Spilotes pullatus, a semi-arboreal species, which feeds on small rodents, amphibians, lizards and even other snakes, is easily found in forests, in open areas such as pastures and trails and can even be seen around human constructions in search of food. Despite being a large snake, reaching up to 3 metres, it’s very agile and not venomous, with yellow and black colors.
Recently, an old skin left after shedding (the process being called ecdysis) was found at the research accomodation, Casa Pesquisa, which in adult individuals occurs on average once a year. This process occurs when the outer layer of the skin, formed by keratin, is replaced by a new one. This exchange takes place when snakes, in general, grow or when the outermost layer is damaged. Ecdysis lasts from 5 to 7 days and during this period the snake becomes more vulnerable to predators as vision is reduced due to fluid accumulation between new and old skin.
One of the researchers who is carrying on his fieldwork at REGUA, Rodrigo Fonseca, has been studying the perception and colonization of reproductive habitats (puddles, flooded fields, streams, etc.) by anuran amphibians and the elements of the landscape (trees and shrubs) favouring this dynamic.
His study includes night field work, where he samples temporary and stablished puddles also capturing and identifying amphibian individuals. He is a Master’s student from the Post Graduate Programme in Ecology at the Federal University in Rio (UFRJ).
During his activities, he quite often comes across with the Blacksmith Tree Frog Boana faber, a species known to form small nests called “pans” where males vocalize to attract females, which in return will evaluate the nest condition and decide whether to use it or not. If the female chooses it, the male performs the bridal hug, also called amplexus, where together they release gametes into the water forming around 3,000 eggs inside the nest.
