Zoo chimp shows people aren’t the only planners

By MALIN RISING, Associated Press Writer Malin Rising, Associated Press Writer – 1 hr 27 mins ago

STOCKHOLM – [Santino] A canny chimpanzee who calmly collected a stash of rocks and then hurled them at zoo visitors in fits of rage has confirmed that apes can plan ahead just like humans, a Swedish study said Monday.

Santino the chimpanzee’s anti-social behavior stunned both visitors and keepers at the Furuvik Zoo but fascinated researchers because it was so carefully prepared.

According to a report in the journal Current Biology, the 31-year-old alpha male started building his weapons cache in the morning before the zoo opened, collecting rocks and knocking out disks from concrete boulders inside his enclosure. He waited until around midday before he unleashed a “hailstorm” of rocks against visitors, the study said.

“More than 6 billion plastic bags are used in L.A. County each year. Disposable bags cost our fiscally strained cities up to 17 cents per bag for disposal (this does not even include the environmental costs). Plastic bags are made from fossil fuels. Americans use over 380 billion bags every year, throw-ing away this precious, non-renewable resource.”

The morning talk was great. Graham Burnett, a historian from Princeton University, took us through the history of cetacean research.

In 1963, major scientists from various fields of cetacean research met together for the first time at the 1st International symposium on cetacean research.

The three fields of cetacean research were stated as:
(1) Hip-Boot Scientists – scientists who worked from whaling stations(and wore hip-boots), like those in Antarctica (RSS Discovery), and collected data from harpooned whales. The discussion of these scientists was conflicted – it seems that the environment was troublesome for some, evidenced by water color and writings depicting the horrendous scene of dead leviathans, but natural for others who saw the whale hunts as very beneficial sources of data.
(2) Bioacousticians – scientists who wanted to understand the sounds produced by dolphins, includes Navy, Schevill, Watkins.
(3) Brain / Behavior / Language – scientists interested in dolphin cognition & social intelligence like Ken Norris, John C. Lilly (yes, in the same breath). The historian reports that the Brain / Behavior / Language scientists have been the most effective group for raising public awareness :)

This meeting was a volatile boiling pot, and resulted in a book edited by Ken Norris, called “Whales, Dolphins, and Porpoises” (1966/1980ish) that includes the discussion at the meeting “verbatium” (though edited…?…)

Burnett spent a good amount of time describing John Lilly’s work. Pre-1964, Lilly was a very respected scientist. He had a lifetime research grant from NSF, as well as major funding from NASA (Lilly:Dolphins ::. Sagan:Aliens). (more maybe later, until then, if you don’t know , the end story is that Lilly gets wiped off science, along with a bunch of future funding, by feeding LSD to dolphins).

The first panel was on whaling, how countries are bypassing whaling restrictions, and what the US can do to decrease whaling internationally.

DJ Schubert spoke about US policy on whaling. The Polly Amendment (citation 22 USC %1978) allows the US to (1) stop trade with countries violating IWC rules, (2) give certificates to countries abiding by IWC rules. In the last 6(+?) years, we have done only #2, which is disregarded by other countries.  Most of US policy on whaling has been maintained by Ted Stevens (the embezzling senator from Alaska) in light of bowhead whale quotas. Needless to say, not very good.

Jonathan Stern & Phil Clapham discussed Japan’s exploitation of article 8 of the IWC rules, which is the article allows nations to continue whaling for scientific purposes.

Jonathan Stern explained that Japan’s science is based on a theory of ecosystem based management. They argue that they are being out-competed by the whales for fish. Because Japan gets most of their protein from the sea, they see the whales as competitors for an essential resource. Stern claimed that the science is fundamentally flawed: removing the top predator in an ecosystem would cause an increase in fish, a decrease in crill, and an increase in plankton (skewing the whole system). Further, Stern reported that fish eat more fish than whales do. Whales aren’t a limiting species, the fish are prey limited, not predator limited, and that the amount of food that the fish have dictates population size.

Phil Clapham investigated the Japan’s claimed science. He said that if competition was the question, Japan’s scientific studies should focus on whale stock size and mortality rates. But, in 18 years, and 1600 dead whales, there has been no scientific advancement. Clapham accused Japanese scientists of “writing their conclusions before starting the study.” The substaintial science that is done was reported by Clapham to be tangental and weird (artificially inseminating whale ovum with cow sperm). Japan’s last IWC report said that the population could be growing, decreasing, or remaining the same, and include no mortality rates.

SPLASH

The second panel was about the program SPLASH, which documents the “Structure of Populations, Levels of Abundance, and Status of Humpbacks” in the North Pacific ocean.

In this project, (1) abundance is documented using photo ID, as well as mark & recapture; (2) Population stock structure using photo ID and genetic markers; and (3) Status, or anthropogenic effects, by analyzing skin cells for biological contaminants.

John Calambokidis and his research study abundance and population stock structure using photo ID. The dorsal fin of whales are captured on film, then compared to other pictures taken down the coast of North America. Calambokidis et  al. report that in the summer, humpbacks are found in multiple sites scattered along the northern coast of North America, from California to the Aleutian Islands. These whales all meet up at the winter breeding grounds, but, save 1 or 2 whales, go back to their same individual group site for summer feeding.  They estimate a population size of 20,000 Humpbacks, a 7% increase since 1966 (after the international moratorium on whaling in 1973).

David Mattila spoke about health of, and human impacts on, humpback whales. He estimates that  >300,000 whales die in entanglements from fishing gear each year, and suggested that populations where no scars are observed may mean populations that die immediately when entangled, or come into contact with larger & lethal equipment (rather than assuming that since there is no visual evidence, it doesn’t happen). As alluded to, he and his team analyze entanglements by looking at the scarring patterns on humpback whale tails. If a whale has a scar across each fluke, is considered evidence that that whale had escaped from entanglement. In the Southeast Alaska population, Mattila estimates 50% of the whales show signs of entanglement. At least 30% of the humpbacks seen off the coast of Hawaii show signs of entanglement.  Many whales arrive to the annual breeding grounds in Hawaii having towed fishing equipment from fisheries in Alaska and Canada. Matilla asked the audience to consider how many whales were dying if 50% showed scarring.

There are two main types of gear that harm cetaceans: small, light, near shore gear such as ropes and lines; and large offshore gear, such as large crab cages. The larger the gear, the more lethal to the whale who comes into contact with it.

Scott Baker heads the genetic analysis studies conducted by SPLASH. His results mirrored those of Calambokidis very accurately. Baker et al. reported that there are 3 pure stocks of humpback whales: (1) those that migrate from Alaska/Canada to Hawaii (2) those that migrate from southern Baja California & Mexico, and (3) populations that migrate from China, Japan, and the Philippines.

Baker reports that for these three populations, there is “strong maternal fidelity that goes back to the ice age.” He made this discovery by analyzing samples of mitochondrial DNA (mtDNA), obtained from bits of skin and bone. mtDNA is passed down through females to their offspring (in all mammals). A geneticist can use mtDNA to create family trees, tracking populations through similarities in the mtDNA gene structure. Baker also pointed out that whaling can cause the demise of an entire population, eradicating the “cultural memory” of a location, or a migration path. This is likely the case, e.g., in the Mediterranean Sea where before there was a population of Sperm Whales, and after heavy whaling, the population no longer exists, and hasn’t returned since the 1973 moratorium.

Killer Whales (Orcinus orca) (& Monterey Bay population)

The last talk of the afternoon was given by Nancy Black, who has conducted a 20+ year study on the killer whale population in Monterey Bay. After a fascinating overview of killer whales (found all over the world, sexually diamorphic, 5-9 year inter-birth-interval, sexually mature at 12-17, populations include post-reproductive females, residents are nice, transients are mean), spoke about the different hunting behavior employed by killer whales.

Transient killer whales hunt a wide variety of other mammals, including seals, sea otters, dall’s porpoise, Risso’s dolphins, pacific white sided dolphins, humpback calves, grey whale calves, blue whale calves (etc.). They employ three different tactics, based on their type of prey.

Seals and sea otters are the easiest targets, since they don’t start to swim away from the killer whales until it’s too late. Orcas use their strong flukes to slap the pinniped out of the water, which sends them flying in the air and kills them. Black reports that mother orcas will sometimes spend a longer amount of time hunting these animals when there is a calf nearby.

Dolphins are harder to catch: the killer whale must first sneak up on the dolphin, then beat them at a chase that ends when the orca moves its body under the dolphin and bucks it until it dies.

Mysticete whale calves (humpbacks, grey, blue, etc.) are generally hunted when they “swim through the wrong part of town.” That is, when they go through the bay, instead of around it in the open sea. Mysticete calves are larger than orcas, creating a different challenge for the orca. The calves meet their end when orcas team up, sometimes adopting roles, to drown them. The tongue and blubber are eaten first.

I had hoped to ask Dr. Black about her provokativ use of words (learning, cultural transmission, etc.) but had only a chance to clarify the reproductive age (12-17), and how post-reproductive females were determined (lots of years of watching them). Perhaps I’ll find her tomorrow.

Re: Prop 8: For Your Consideration

September 16, 2008 · 9 Comments

A Facebook message sent to me yesterday said the following:
Prop 8: For Your Consideration
I just wanted to share this with you all so you would understand what voting no on Prop 8 would do…..

What are the six consequences if Proposition 8 Fails?

1. Children in public schools will be taught that both traditional
marriage and same-sex marriage are okay. The California Education Code
already requires that health education classes instruct children about
marriage. (§51890) Therefore, if the definition of marriage is
changed, children will be taught that marriage is a relation between
any two adults. There will be serious clashes between the secular
school system and the right of parents to teach their children their
own values and beliefs.

2. Churches will be sued if they refuse to allow same-sex marriage
ceremonies in their religious buildings that are open to the public.
Ask whether your pastor, priest, minister, bishop, or rabbi is ready
to perform such marriages in your chapels and sanctuaries.

3. Religious adoption agencies will be challenged by government
agencies to give up their long-held right to place children only in
homes with both a mother and a father. Catholic Charities in Boston
has put an end to its adoption work, deciding to abandon its founding
mission, rather than comply with state law requiring that gays be
allowed to adopt children. (Boston.com)

4. Religions that sponsor private schools and which provide housing
for married students will be required to provide housing for same-sex
couples, even if it runs counter to church doctrine or lose tax
exemptions and benefits.

5. Ministers who preach against same-sex marriages will be sued for
hate speech and could be fined by the government. It has already
happened in Canada, one of six countries that have legalized gay
marriage.

6. It will cost you money. A change in the definition of marriage will
bring a cascade of lawsuits. Even if courts eventually find in favor
of a defender of traditional marriage (highly improbable given today’s
activist judges), think of the money – your money, your church
contributions – that will have to be spent on legal fees. And think of
all the unintended consequences that we cannot even foresee at this
time. Where will it end? It’s your children, your grandchildren, your
money, and your liberties. Lets work together to protect them.

My Reply:

Hi Humans,

Nina – I want to thank you for bringing my attention to Proposition 8. I had heard it was to appear on the ballot, but hadn’t yet done much reading on the matter.

I’m a little unsure how to best reply. My first response to reading this article was to google the referenced information, sensing that it may be a sort of propaganda.  It’s been about an hour now, and my best guess is that the information came from a flyer created by the California Family Council (CFC). This comes from a August 28, 2008 article written by the Associated Press (http://www.usatoday.com/news/politics/election2008/2008-08-24-gay-marriage_N.htm), then from googling “Ron Prentice” to find that the “coalition of religious and social conservative groups” mentioned in the article is the CFC.  The CFC, as you may read, is the group that created proposition 8, thus may not be the most objective source for information.

Good luck finding an “objective source.” The strongest arguments will be made on either extreme end, and this conversation would go nowhere except to end in a heightened stance of name-calling (e.g. “liberal extremist”, and “conservative extremist”). I’d rather not do that. I think that the best thing to do, if we’re looking for objectivity on the issue, is to look at the facts the best way we can. Here’s a shot at #1. (I’m not a pro on this issue, I’m just going to try my best here):

(1). Is it so bad to teach children that it’s okay to accept their fellow human beings as the beautiful people that they are? I think that’s what society has been striving for when it teaches us to look past artificial barriers such as race, creed, religion, and gender. Perhaps it’s even part of what Jesus taught when He said to “love thy neighbor.”

Secondly, it seems from various blog posts that we should really take a look into the CA Education code before making assumptions. For example, the only part of section 51890 that refers to family is section D which states,

51890.  (a) For the purposes of this chapter, "comprehensive health
education programs" are defined as all educational programs offered
in kindergarten and grades 1 to 12, inclusive, in the public school
system, including in-class and out-of-class activities designed to
ensure that:
   (1) Pupils will receive instruction to aid them in making
decisions in matters of personal, family, and community health, to
include the following subjects:
(D) Family health and child development, including the legal and
financial aspects and responsibilities of marriage and parenthood.

(http://www.leginfo.ca.gov/cgi-bin/displaycode?section=edc&group=51001-52000&file=51890-51891).

The point I want to make here, is that as Americans, we are given the right to vote. We are given the right to free speech, the right to question the information we are given, and the right to access more sources. We are also given a responsibility, to our fellow Americans, and our fellow people, to cast an informed vote. This is a moral question of voting with a crowd, or having the independence to consider an issue with the resources we all have as free citizens of the United States of America. This argument works for both extremes.

It is simple to google “six consequences if proposition 8 fails” and find a variety of opinions on the matter. It is a bit more time consuming to do the fact checking and to find legitimate/objective sources. But, it is very easy to identify that this is a piece of propoganda – the concerns voiced in the “6 consequences” are written in an alarmist fashion, and constitute illogical, unfounded, and ungrounded sentiments.

One person, Joyce A. Rogers, took on the list point-by-point, did her homework, and cited her facts. It’s a great read.  You can read the full article here (though the original article appears here). You’ll notice that the two sources are from liberal news sources. The article is undoubtedly biased, but if you can bear to read through a bit of bitter sarcasm, you’ll find it to be factual, and its allegations easily sourced (i.e. if you don’t believe her, you can click on her sources to see if you might believe them). Though I’ll admit that battling one extremist view with the opposite extremist view is not the best way to come to a common ground, I would argue in this case that the article I’ve linked is more credible than the original “6 consequences” as it points to the exact places where it’s information came from, and the information from the “6 consequences article” cannot be easily tracked or validated (suggesting that it might be made up).

Obviously, I have expressed an opinion here. However, I have written this with the hope that the two sides of this issue can communicate, and as I said in the original facebook comment “in hopes that together we can share information and form a collective objectivity to this issue.”

Peace and love to all,

Whitney
