Dragon Praying Mantis – Projeto Mantis

The Mantis Project is made up of Brazilian biologists Leonardo Lanna, Savio Cavalcante, João Felipe Herculano and designer Lucas Fiat, who are very keen on insects.

They met at UNIRIO University in 2015 and soon discovered that there was no-one studying the impressive Mantis order, Mantodea.    There are over 430 genera and 2400 species divided in 15 families worldwide and they believed there could to be many in the Atlantic Rainforest.

Leonardo and his friends got together and started their first field trips in Valença a town in the South-West of Rio State and the following year caught an undescribed species, a first for science.   Their primary interest was not in just finding and identifying these amazing creatures but also raising Mantises, showing people that these insects are not dangerous or life threatening but beautiful, gentle creatures that indicate the quality of the habitat.

With their increased passion the Team started to work at Rio de Janeiro’s Botanical Garden.   They submitted a project to National Geographic in 2016 and received the funding to research the State of Rio and increase the list of the 12 genera already known there.

However, Rio de Janeiro state is very large and their study varied from sand dune habitat known as “Restinga”, Mangrove habitat to the lofty “Paramos” or sedge growing waterlogged habitat found at close to 2,600 metres above sea level in Itatiaia (two hours drive west of Rio city) where temperatures fall below zero at night in the winter.

The team also included REGUA in their research and arrived to stay at its field station in December 2017.

One mystical Praying Mantis is the Dragon Mantis, Stenophylla cornigera described by English entomologist John Westwood in 1843.   It resembles depictions  of miniature dragon and the young biologists had never seen one.    Imagine their delight when on the first night, an example arrived at the REGUA light and they could see it in full detail.

The team of biologists collected not only one.    A second was found a couple of days later from a forest fragment just seven kilometres away, showing that the species is present along the Guapiaçu valley.    A report and video was sent to National Geographic magazine which was hugely successful.

The overall research revealed another nine genera taking the total Mantodea list in Rio de Janeiro State to 21 genera, of which 15 have been found at REGUA.

Leonardo says that REGUA is at an elevated level of habitat protection.   Perhaps the significant area of remaining forest cover, full altitudinal gradient and low demographic pressure all influence but the fact is that as an indicator species, Praying mantises reveal that the REGUA conservation project is working in the right direction.

New damselfly species discovered at REGUA by Tom Kompier

We are delighted to announce that a new Damselfly species for science of the Forcepsioneura genus found at REGUA by Tom Kompier has been named Forcepsioneura regua sp. after the reserve. This is one of two new damselfly species described by Dr. Ângelo Pinto with Tom as co-author in their paper In honor of conservation of the Brazilian Atlantic Forest: description of two new damselflies of the genus Forcepsioneura discovered in private protected areas (Odonata: Coenagrionidae), published in the zoological journal Zoologia.

Tom’s contribution to our knowledge of dragonflies and damselflies has been magnificent and provides valuable evidence of the importance of this reserve. He started his research in 2012, making several visits during the varying Neotropical seasons, travelling from the Netherlands to REGUA throughout 2013 and identifying 204 species in this region. Tom was supported by Dr. Ângelo Pinto and Professor Alcimar Carvalho of the Natural History Museum/UFRJ. This resulted in the publication of A Guide to the Dragonflies and Damselflies of the Serra dos Orgaos, South-eastern Brazil (see details on our publications page).

The principle difference between dragonflies and damselflies is the position of the wings when resting. Dragonfly wings lie transversal and damselfly wings lie flat alongside their abdomen. 204 species have been recorded at the reserve and REGUA hosts annual visits to see the odonate and in an eight day visit it is possible to see at least 160 species!

Congratulations and thank you Tom for the magnificent contribution your work has given us and you have inspired us to continue to develop studies in ants, butterflies and spiders.

Second Tapir release begins!

Following the arrival of three lowland Tapir (Tapirus terrestris) at REGUA last January, a further two males and a female named Jupiter, Valente and Flora arrived at REGUA in Guapiaçu as part of the continued Tapir reintroduction programme at REGUA on Sunday June 10th.    Sadly, we sustained the loss of the large adult male from pneumonia in March so these three new individuals were a most welcome addition to the remaining population, a mother and adolescent tapir who are very well.

This reintroduction project has been carried out in partnership with Professor Fernando Fernandez, Maron Galliez and Joanna of the Federal University of Rio de Janeiro (UFRJ) and approved by the Rio de Janeiro State Environmental Department (INEA) as well ICMBio.

The tapirs arrived after a tiring 24 hour trip of over 1,000 km from the Klabin conservation project in Northern Paraná State. They were transported in their travelling cases but had behaved admirably and arrived quite calm.

Following much local interest, the cases were promptly taken to be unloaded and released in their two and a half acre quarantine pen created especially for them within a secluded part of the wetlands. The quarantine area has a small pond in which to play and enjoy.

Lowland Tapir has been extinct in the state of Rio de Janeiro for over 100 years and the arrival of these animals at REGUA represents the very first reintroduction of its kind in Rio de Janeiro state.    REGUA starting reforesting lowlands in 2005 with the support of the World Land Trust and in 2005 created RPPN status which protects these restored forests for the future.

Lowland forest has virtually been eliminated in the State and REGUA’s protected area of 300 hectare Atlantic Rainforest adjacent to the enormous Três Picos State Park looked a very attractive area that could guarantee sufficient habitat for the species.

Being herbivores, tapirs consume all the fruit they can find on the forest floor. Feeding on fruit and walking large distances in the forests, they are regarded as the ‘gardeners of the forests’. The UFRJ team understood the need for reintroductions as a means to learn more about this species and their adaptability whilst REGUA wants the animals to spread tree species, increasing forest diversity and ensuring its resilience on the long term.   Likewise, captive breeding programmes are only too delighted to support such well conducted release programmes as it provides the justification for breeding these lovely animals in captivity.

Until their supported release, and like their predecessors Eva and Flokinho the three tapirs will enjoy a diet of fruit and vegetables, up to 8 kilogram per animal per day together with dried maize, to keep them well nourished.  Professors Maron and Joanna will keep their eye on them ensuring that the radio collars are not bothering them and they like their diet. After their release they will find fruit and maize nearby, but like most native animals they will probably prefer to roam and return to the solitary lives they enjoy.

Their release will provide valuable information as to their wanderings and habitat preferences, but there are already camera traps in the pen to check on their nocturnal behaviour and later more will be placed in the forest.

Exciting times ahead for our tapirs and for our biologists!!

IUCN Head of Research visits REGUA

Last weekend REGUA received Thomas Brooks, Head of Research at Geneva for IUCN.

In between seeing birds in the day and waiting for the owls to call in the evening, we discussed the importance of monitoring, something talked about at the recent World Land Trust conference in Thetford UK.

He also asked us about long term sustainability.    I told Tom that we believe REGUA will continue to grow and reach to tourism, education and research income streams and that we look at the protection core costs such as Ranger work being covered by Eco-service payments.

As there is increasing evidence that forests produce water, we believe that grants will be available in the near future that provide annual fee given to those proprietors who have forest cover.

 

Any Myrmecologists out there?

Ants belong to the Formicidae family, one of the most important in Nature,  pillars of the ecosystem.   Divided into Tribes, the Atta and Acromyrmex  are very common in our Neotropical forests and though we worry about their action in freshly planted forests, they are very important in the established forest harvesting and cultivating their fungus on which they feed in their underground homes.

Their vast system of perfectly ventilated tunnels and chambers permits precious nitrogen to reach the roots of trees.

We are trying to identify the most common species at REGUA but we expect to have between 400 and 450 different species.   Taking photographs is notoriously difficult, for aside being small, they move and are often camera shy.

If you want a challenge and wish to visit us spending your time helping us to get some images to help with developing a field guide, drop us a line and we would really love your company.

 

Dutch herpetologist at REGUA

Masters student Hidde de Graff enrolled at University of Amsterdam has come to stay for three months at REGUA studying amphibians.    Professor Wouter Halfwerk organised Hidde’s stay here with Brazilian Dr. Mauricio Almeida and he has been conscientiously at work in the field.

Hidde is been analysing sound tracks from deliberately located microphones recording night sounds in forest fragments as a way to detect and identify the amphibian species present.    Every quarter of an hour those frogs calling will be recorded and later as he studies the sonograms, he will be able to identify the species present.

Dr Mauricio carried out a similar survey a few years ago and Hidde will be able to compare the results and see if there has been any species change and evaluate how accurate his findings are in terms of species identification.

Rildo litter sampling

The Atlantic Rainforest has been subject to enormous change over the years and many species are suffering as a result of the forest vegetation cover change and, of course, hunting.

REGUA received UNESP (São Paulo State University) researcher Carla Martins Lopes with a team of three researchers.   They are sampling leaf litter at the higher elevations of the Reserve to seek residues of DNA that can offer identification of the species that lived and frequented the same area in the past.

The World Land Trust Keeper of Wild Ranger Rildo da Rosa Oliveira guided the group to the top of the green trail, gathering leaves and bringing them down to our research laboratory.

We are very interested in the results, as this is a very new area of research sampling, and may offer some exciting surprises.   Perhaps we can build up images of the animals that occupied these forests in the past, such as the Jaguars, Tapirs and White-lipped Peccary!

 

Come and see the amphibians at REGUA

The Atlantic Rainforest at REGUA is well protected and expanding, and one of the prime habitat quality indicator species are amphibians.  Are the populations stable or declining?

Researchers are always interested as their population numbers reflect air quality and air humidity levels, which in turn are affected by forest cover.   There are over seventy amphibian species at REGUA and with programmes in forest protection and expansion, all species appear to be in good shape.

One genus that attracts attention is the Atlantic rainforest endemic Horned frog which we found on the green trail recently.    Both Proceratophrys appendiculata (also known as Guenther’s Horned Frog) and Proceratophrys boiei were seen.   They live in the leaf litter in forests up to an altitude of around 1200m, and spawn in forest streams.

Both species are relatively common at REGUA and all visitors like to pick them up and get a closer look at them. They sit immobile and looking rather glum, patiently waiting to be returned to the ground when they hop off into the leaf litter and are quickly almost impossible to refind.

Danish Travel Fund land is forested

Ready to plant 2017 (© Nicholas Locke)

The amazing thing about planting trees is that they will grow with a little effort, dedication and perseverance.

The area of the Matumbo Gap acquired by the Danish Travel Fund is an example of such an area.   Planted in early 2017, the area a year later has already closed and the grass has virtually gone, crowded out by the strong saplings as they drink up the generous Brazilian rainfall throughout the summer, and grow towards our sunlight .

REGUA planted over 25,000 trees in this area some of which were also funded by the World Land Trust’s  “Forests of the Future” initiative.

The mix of over 150 native species are growing very well and REGUA has engaged the Rio Rural University in monitoring plant plots to measure growth.

Water Monitoring

A windy and cloudy Saturday full of activities as the Education Officers of the Guapiaçu Grande Vida team held a student training course.

They are being taught to use the water-monitoring kit which they will use in the Macacu and Guapiaçu rivers.    Arriving in the morning for breakfast they left after lunch with a certificate acknowledging they had completed this twenty hour course in three sessions.

Water testing

The syllabus included topics such as river basin management, mapping, environmental education and it’s relevance as a tool for conservation,  use of trails and open public areas with an educational approach, water cycle and water sampling for physical and chemical analysis.

Another successful day with enthusiastic students and tutors.
