My first-year students & I are currently studying plants. This is actually something of a balancing act from my perspective as a reasonably large proportion of the class didn’t study the ‘diversity in plant structure & function’ standard back in year 12 (or don’t remember doing so), so I’ve got to bring them up to […]

A few posts back I wrote about the aerial roots of strangler figs: beginning as thin hair-like structures, they thicken into strong cables & eventually their interlaced networks engult the trunk of the hapless host tree. Then there are the pneumatophores of mangroves and bald […]

But we’d probably have walked straight past some wonderful plants & animals if it wasn’t for our guide, Ross. For example, the first time we encountered a Boyd’s forest dragon, all […]
