The Theory of Island Biogeography is remarkable because it suggests that patterns of species co-existence are the consequence of chance, history and random dispersal. Before its publication, community ecologists generally assumed that species co-existence was due to deterministic niche-assembly, where the number and relative abundance of species were a result of ecological niches and the functional roles of each species.
Like the theory itself, MacArthur and Wilson have also reached cult-like status. Perhaps a most telling way of illustrating this fact is not by listing the prizes awarded to these two men (and there were many), but rather by listing the academic prizes named after them! The Ecological Society of America, for instance, awards the ‘Robert H. MacArthur Award‘ to eminent mid-career ecologists and the American Society of Naturalists grants the ‘Edward O. Wilson Naturalist Award‘ to mid-career researchers who make significant contributions to a particular ecosystem of group of organisms. Similarly, the International Biogeography Society has the ‘MacArthur & Wilson Award‘ for notable contributions to the field of biogeography. Needless to say, MacArthur and Wilson are very influential and well-respected by contemporary ecologists (well, in most cases…).
The funny thing is that their paradigm shifting idea was actually proposed two decades earlier, by the less well-known lepidopterist Eugene Munroe. Continue reading →
Although ecology doesn’t have many general laws, one most likely to qualify is the species-area relationship. If you walk through a field in a straight line and count all the different species you come across, you’ll notice that the total number of species increases as you progress along your straight path. After a while, however, you’ll start seeing the same species over and over again until you eventually find that you’re no longer spotting any new ones. This is the asymptotic species-area curve. While the exact mathematical form of the relationship is still hotly debated, it is safe to assume that it is an increasing function that reaches a plateau once all the species have been encountered.
As an aspiring ecologist, I am well aware that publishing a paper in Natureor Sciencewould give my career an incredible kick-start. But, like so many others, I didn’t know how to get my name printed on the glossy pages of the two oldest and most prestigious weekly scientific journals. So I did what any good scientist would do – no, this time I didn’t check Wikipedia – I knuckled down and poured over the pages in these celebrated periodicals. I spent countless nights without sleep, trying to crack the code.
Just as I was about to give up, I saw a glimmer of hope: a golden thread linking the fortunate submissions to these two behemoths of academic excellence. I managed to reverse-engineer the path to success and I will be so generous to share my astounding findings with you. But before I do that, a word of warning: my how-to guide only applies to ecological studies. Physicists, physiologists and… um… uh… anyone else (I ran out of alliterative scientific sub-fields) will have to find their own strategies. Continue reading →
There are many metaphors that use running a marathon or climbing a mountain to describe the process of ecological research. This post will not have any. No, this post will ignore linguistic devices and will shine the spotlight on behavioural psychology instead. Continue reading →
As a PhD student, I spend my days trying to do good ecological research; as are thousands of other aspiring ecologists around the world. Good work, however, is useless unless others know about it. Prospective employers, potential collaborators and other researchers must recognize my effort for it to be valuable, because unread research is obviously worthless. Continue reading →
A few of my friends and I started a debate on the impact of war on biodiversity conservation over lunch one afternoon. On the one hand, we argued, civil conflict can improve the state of biodiversity. One such example is the demilitarisation zone between North and South Korea, which is considered one of the most well-preserved involuntary conservation areas in the world. On the other hand, however, conflict can cripple conservation attempts: Saddam Hussein’s draining of the Mesopotamian Marshes in Iraq for strategic purposes during the Gulf War is a typical case in point. Since we are all aspiring scientists, we wondered whether we could aggregate all the known cases where biodiversity was influenced by any form of civil conflict to (a) recognize some general trends and (b) identify the complex socio-ecological dynamics of various forms of civil strife.
