Tuesdays With Turtles – Hometown Edition

Byoliveridley

I grew up in Chennai and worked with the Students’ Sea Turtle Conservation Network in the mid ’90s. It’s nice to see an article on them in the city’s biggest newspaper.

The Hindu : Tamil Nadu / Chennai News : Olive Ridley hatchlings go home

CHENNAI: Scores of newborn Olive Ridley turtles entered their natural habitat — the sea — under the watchful eyes of conservationists at Elliots Beach, Besant Nagar, here early on Sunday. Conservationists said nearly 75 eggs hatched on Sunday alone and most of the young ones were safely released into the waters. But about 25 eggs reportedly did not hatch and some were stillborn. Volunteers of the Students Sea Turtle Conservation Network (SSTCN) annually collect Olive Ridley turtle eggs from the Besant Nagar coastline upto Neelankarai, a fishing village beyond Tiruvanmiyur. The eggs are then taken to a hatchery at Oorurkuppam, a fishing village located behind the Theosophical Society premises. It takes 45 days for the young ones to hatch.

In Chennai, and most of South India, the adult sea turtles are not poached, only the eggs. Also, it is not possible to just secure the nest with “do not poach” notice! So the eggs need to be relocated to a hatchery where they’re re-buried. For more on sea turtle “management” in India, I would suggest visiting Kartik Shanker’s excellent website.

    Great Turtle Race

    Follow eleven turtles as they sprint from Costa Rica to near the Galapagos. Each of them has a corporate sponsor, and at 20 miles an hour, they will get there in a couple of weeks! I think Billie’s going to win, but the leatherback turtle is in bad shape, endangered due to poaching, adult mortality and habitat loss. They may be gone very soon.

    Here’s the flickr page for the race, some beautiful pictures already.

  • Now we know where Juvenile sea turtles Hide

    Byoliveridley

    You see the hatchlings as they dig out of the nests all small and helpless and make a beeline towards the sea. You see the adult female as she comes back to lay her eggs. You see adult males when you go snorkeling , but the juveniles had kept a low profile, until now…

    Sea turtles’ mystery hideout revealed – LiveScience – MSNBC.com

    Once sea-turtle hatchlings hit the surf, they vanish for up to five years. Where the half-dollar-size tots spend these ‘lost years’ while ballooning to the size of dinner plates has been a mystery, until now.

    New research, published in the online edition of the journal Biology Letters, indicates the green sea turtles (Chelonia mydas) hide out in the open ocean, where they feast on jellyfish and other marine creatures.

    Turns out that they’ve been “hiding out” in the open ocean eating meat to augment their vegetarian adult diet. I have not seen the paper (reference below), but the study was based on an analysis of their shell content. Carbon and Nitrogen isotope analysis was used as a marker for diet and location.

    Brotherless Night – Go Read

    Byoliveridley
    Brotherless Night is the book I wanted to read, so I wrote it. VV Ganeshananthan
    Book cover of the book Brotherless night by VV Ganesananthan

    I grew up in Chennai in the 80s and got to witness the Sri Lankan civil war from just across the border. I read about it mostly from the Indian English news media (The Hindu, Indian Express) and remember many parts of the conflict: The initial profusion of Tamil groups, the LTTE takeover, the quick suppression of peaceful/non-violent voices by the LTTE, the Indian “peace” mission, and then much of the mayhem that followed, including the killing of Rajiv Gandhi. My opinions were filtered through my pro-Sanskrit anti-Tamil Brahmin upbringing and I don’t remember being especially sympathetic to the cause back then.

    This book really took me back and filled in the blanks. I learn history best when told through the experiences of those affected the most, the women, children, “civilians”. It’s a beautiful, extremely challenging history lesson on the Sri Lankan war told from the viewpoint of a young woman growing up in Jaffna. VV’s writing makes you read through the horror of war, the clear and repeated threads of who suffers and how no one involved in violence is “noble” or “heroic”. Read it if you are able, trigger warnings all the way with violence, sexual violence, family violence 🙁 It is however a story primarily of resistance, survival and how important it is to catalogue the horrors of war as they are happening, and not let that story get buried in traditional war jingoism.

    In this world we’re in right now, dominated by war coverage and the daily unchallenged assertions by those committing war that they are “right”, “honourable”, “just”, etc., reading accounts of war from the perspective of those most affected are a reminder. They are a reminder that when you commit to continuous violence, even if it starts as self defense or resistance, there’s no nobility there, no heroism: you’re killing human beings, you’re destroying lives, homes, gardens, libraries, schools, music, love and everything that makes us human. I really wish all war coverage focused on what is lost, not on who gained a bridge or how the great leader sitting in his well-protected mansion is waging the war.

    Sea Turtle News o' the day – Global warming edition

    Byoliveridley

    ScienceDaily: Scientists Warn Of Climate Change Risk To Marine Turtles

    North American marine turtles are at risk if global warming occurs at predicted levels, according to scientists from the University of Exeter. An increase in temperatures of just one degree Celsius could completely eliminate the birth of male turtles from some beaches. A rise of three degrees Celsius would lead to extreme levels of infant mortality and declines in nesting beaches across the USA.

    Here’s the paper.

    Like a lot of other reptiles, the sex of the hatchling is dependent on nest temperature. Warmer temperatures make female turtles (my mnemonic was hot females!), and even warmer temperatures just kill the eggs. But, I wonder if the turtles would adapt by nesting a little earlier. I don’t think it is yet clear when turtles decide to nest. If it is based on sea temperature, then they would eventually figure it out. This paper from 2004 appears to conclude that loggerheads in Florida do nest earlier than before, so there is hope.

    John F. Weishampel, Dean A. Bagley, Llewellyn M. Ehrhart (2004) Earlier nesting by loggerhead sea turtles following sea surface warming Global Change Biology 10 (8), 1424–1427

    The onset of spring, noted by the timing of wildlife migratory and breeding behaviors, has been occurring earlier over the past few decades. Here, we examine 15 years of loggerhead sea turtle, Caretta caretta, nesting patterns along a 40.5 km beach on Florida’s Atlantic coast. This small section of beach is considered to be the most important nesting area for this threatened species in the western hemisphere. From 1989 to 2003, the annual number of nests fluctuated between 13 000 and 25 000 without a conspicuous trend; however, based on a regression analysis, the median nesting date became earlier by roughly 10 days. The Julian day of median nesting was significantly correlated with near-shore, May sea surface temperatures that warmed an average of 0.8°C over this period. This marine example from warm temperate/subtropical waters represents another response of nature to recent climate trends.

    So the truth lies somewhere between easy adaptation and giant swarms of frustrated female turtles!

    When I first read that Benazir Bhutto’s 19 year old son would become chairperson of the Pakistan Peoples’ Party, and “also continue his studies”, I though I was reading the Onion, but it is true, and Tariq Ali lays into the feudal cabal that is the Bhutto family.

    On 30 December 2007, a conclave of feudal potentates gathered in the home of the slain Benazir Bhutto to hear her last will and testament being read out and its contents subsequently announced to the world media. Where Mary was tentative, her modern-day equivalent left no room for doubt. She could certainly answer for her son.A triumvirate consisting of her husband, Asif Zardari (one of the most venal and discredited politicians in the country and still facing corruption charges in three European courts) and two ciphers will run the party till Benazir’s 19-year-old son, Bilawal, comes of age. He will then become chairperson-for-life and, no doubt, pass it on to his children. The fact that this is now official does not make it any less grotesque. The Pakistan People’s Party is being treated as a family heirloom, a property to be disposed of at the will of its leader.Nothing more, nothing less. Poor Pakistan. Poor People’s Party supporters. Both deserve better than this disgusting, medieval charade.
