Rock Hand Specimens

22 September 2010

Rocks for Geology Lab. I've looked on the internet and the best and easiest way to find the properties of rocks is on www.wikipedia.org. Just type in the name of the rock in the search box of Wikipedia. You will not find a couple of the specific rocks, like different types of sandstone and limestone, but if you read the main article you will get some idea.

Can anyone guess what rock is this one on the left side?

चींटियों से डरते हैं हाथी

चींटियों से हाथी को ख़तरा महसूस होता है

I found this news on the BBC website.

विशालकाय हाथी चींटियों से डरते हैं, ये बात हम बचपन से सुनते आए हैं लेकिन शोध ने भी इस बात की पुष्टि की है. पूर्वी अफ़्रीका में जहाँ पेड़ों की संख्या घट रही है वहीं हाथियों की संख्या बढ़ रही है. वहाँ हाथी अपने भोजन के लिए पेड़ों को नुकसान पहुँचाते हैं.

r- and K- Strategies Table

Singh Sir had told us to to create a table about r- and K- strategies. Here is one I found from http://pespmc1.vub.ac.be/papers/r-KselectionQOL.pdf. It is taken from Pianka and Wilson.

Table 1 summarizes the typical differences between organisms that follow either type of strategies [cf. Pianka, 1970; Wilson, 1975].

r-organisms	K-organisms
short-lived	long-lived
small	large
weak, vulnerable	robust, well-protected
fast maturation	slow maturation
prone to take risks	risk averse
opportunistic exploiters	consistent exploiters
less intelligent, experienced...	more intelligent, experienced...
strong sex drive	weak sex drive
reproduce at an early age	reproduce at a late age
large number of offspring	small number of offspring
small relative size at birth	large relative size at birth
little care for offspring	much care for offspring
variable population size	stable population size

Table 1: typical differences between organisms that follow r-strategies (e.g. rabbits, sparrows), respectively K-strategies (e.g. elephants, parrots)

Are you having trouble following our Ecology class? This book was recommended by our seniors. They said it was very helpful.

It is available in our department library. Also available to buy in photocopy form in Lanka. It is not available at Student Friends bookstore nor University bookstore in Lanka.

This book has some good topics in it, for example:

Ecosystems Nutrient Cycling

Description of the book:

Ecology,Environment & Resource Conservation
Singh, J.S., Singh, S.P. & Gupta, S.R.

This is the first comprehensive textbook of its kind on ecology and environment published in India by three leading ecologists. Every post-graduate student of ecology must have a personal copy.

Over the year, the scope of our scientific understanding and technical skills in ecology and environmental science have widened significantly, with increasingly greater emphasis on societal issues.
