AGM?KB 15 July 2023

Dear members & friends, Our talk in August is by Hans Hazebroek, our MNSKB member, who is a Geologist and Naturalist and wrote several books (National parks of Sarawak, Danum Valley, Mulu, Bako, Maliau Basin) as well as geology chapters in 5 books published by UNIMAS. Date: Wednesday 16 August 2023 Time: 7.30 - 9.00 pm Venue: Telang Usan Hotel, Lot 340-345, Ban Hock Road, 93100 Kuching Registration form :https://forms.gle/27FmWV1MZFuCuZ9r9 Only people who registered are welcome since seating is limited to 60 pax. Registration closed on Tuesday 15 Aug. Abstract: In the latter part of the 19th century naturalist and explorer Alfred Russel Wallace was traveling the islands of today’s Malaysia and Indonesia: the Malay Archipelago. This is an immense group of more than 18,000 islands extending over 5000 km from west to east between 95° and 141° E, and crossing the equator from 6° N to 11° S. His extensive fieldwork brought Wallace to the profound insight that the geographical distribution of the hornbills and other animals that he saw was the result of a long and complicated series of geological and organic changes which continuously modify the earth’s crust and the things that live on it. The focus of my talk is to illustrate, with animated geological maps, the gigantic collision of the Australian tectonic plate with the Eurasian plate. Today's Malay Archipelago is the result of this enormous slow-motion crash that took more than 20 million years and is ongoing. GPS measurements indicate that today’s relative motions between tectonic plates in Indonesia vary from 7.7 to as much as 11 centimeters per year. Subduction, when one tectonic plate slides beneath another, triggers earthquakes and causes volcanoes to erupt. Collision between tectonic plates can uplift landmasses such as the entire island of Timor, and build mountain ranges such as the huge mountainous backbone of the island of New Guinea. Following collision, the proximity between the two plates carrying the Australian and Asian floras and faunas respectively creates zones where these floras and faunas merge and interact. The bird and mammal distributions today, from Borneo to Sulawesi, to Maluku, and finally to New Guinea, provide plenty of fascination to further illustrate this in a follow-up talk. Regards, Cynthia Lobato MNSKB Secretariat

Between the Malay Peninsula and the islands of Sumatra, Borneo and Java is the shallow sea bed of the Sunda Shelf with water depths considerably less than 200 m. The Sunda Shelf together with much of the lowlands of Sumatra and Borneo is a region that is largely free of earthquakes and is known as Sundaland. Sundaland forms part of the continental core of the region. (Modified after Hall, 2009)

In Memory- Rebecca D’Cruz

Rebecca D’Cruz, born on 4 February 1964 passed away peacefully, surrounded by her family on 29 May 2023. She was fondly known as ‘Becky’ to her friends and many of us who knew her through here extensive involvement in the Malaysian Nature Society. 

Nature, wildlife, and animals were a lifelong a passion and leading to work with Wetlands International and the RAMSAR Secretariat, along with her consultancy work. She was passionate about the natural world; she was an active member of  SSPCA (Society for the Prevention of Cruelty to Animals) and MNSKB (Malaysian Nature Society – Kuching Branch). She was the Secretary of MNS-KB for about 5 years from 2002 and then the Chairperson from 2008 to 2010. 

The visibility and the variety of activities dramatically increased when Becky arrived on the scene. It was during these years that the branch organised a clean-up of Mount Santubong, started running a weekly article in the Borneo Post (a Kuching-based paper), curated exciting trips such as those to Talang Talang (Turtle Islands), dolphin and crocodile watching. Her enthusiasm was contagious, and she was never short of helping hands to turn ideas, hers, and others, into reality. 

She will be remembered around the world for her foresight and her profound love for the natural world. She will be remembered for thought-provoking discussions and enabling those around her to look beyond boundaries. 

It was with heavy hearts and sadness that we learnt of Becky’s passing but she lives on in the hearts of all who were in touched by her brief but powerful passage on Earth. 

We extend our deepest sympathy to her beloved and devoted husband, Anthony Sebastian, and her extended family and friends. We are so very sorry for your loss. 

 

In deepest sympathy

Rose Au, Batrisya Teepol, Cynthia Lobato, Jason Teo, Solomon Hii, Faith Au, Hilda Jelembai and all members of the Malaysian Nature Society Kuching Branch.
