Heavy metal remediation: Defusing the ticking chemical bomb

“Conflict” Picture made by San Jose Think about these questions: 1. Do you understand what is meant by heavy metal pollution?2. Do you know which heavy metals cause pollution? 3. Do you know which methods can control and reduce heavy metal pollution? 4. Have you ever had a heavy metal…

Native plants bring all the (wana)bees to the yard

Pollination is a vital service that many insect species do us the honour of performing. Pollinators allow us to enjoy the many different flowers, fruits and vegetables that grow as a result. In New Zealand the exotic honey bee (Apis mellifera), along with the bumblebee, is the most abundant pollinator….

An ode to Mt Kaputar National Park: A little piece of New Zealand in a wide, brown land

Tim Curran is a Senior Lecturer in the Department of Pest-management and Conservation at Lincoln University. Here he shares his passion for a little bit of New Zealand in Australia. Mt Kaputar National Park, in northern New South Wales, is my favourite national park, for several reasons. First, there is…

Tree guards and weed mats: is protection worth the cost?

Back when I started as a fresh-faced lecturer at Lincoln University in the mid 90s I contributed to a third year class called Wildlife Management.  Graham Hickling was the main lecturer and provided the heft of wildlife management. He had lots of hands-on experience in working with possums, stoats, rabbits…

Can a micro-organism help replace fossil fuels with biofuels?

The world we are living in is so dynamic and vibrant. Let’s imagine for a while. What if the world suddenly runs out of coal, gas and oil. It is not hard to predict that the vehicle tanks would become dry, airplanes would be grounded, many industrial processes would be halted,…

A range of different ferns

The fern is emblematic of New Zealand, appearing on most of our national sports teams and as a default for our nonofficial flag. The fern seems like a good choice to represent the people and places on our shaky islands. Ferns are unassuming, green and not flashy, getting their ecosystems…

Kicking up a stink for the beneficial re-use of biosolids

Just 5.5% of New Zealand soils have enough natural fertility for food production. Yet here in NZ, with our trademark ‘no.8 wire can-do’ attitude, you’ll find we manage to produce a very large amount of food. When you think about it though, that’s a hefty amount of no. 8 wire…

What’s up with NZ sand dune habitats? Do a PhD and find out

Opportunity for PhD study: Quantifying ecosystem function in New Zealand sand dune habitats Understanding causes of variation in ecosystem function is critical for conserving and restoring ecosystems in the face of global change processes, such as climate change, land use change and species invasions. Key functions of sand dune ecosystems…

What’s up with alpine tussock grasslands? Do a PhD and find out!

A great deal of our ecological understanding of community patterns and processes is based on ‘snap-shot’ and short-term datasets. Research using long-term and time series data shows that community datasets collected over longer periods of time can be critical for predicting change. We are looking to recruit one or more…

Pack up you troubles: saving entire ecosystems from climate change by moving them

As the climate continues to change, entire ecosystems are becoming increasingly threatened by shifting abiotic conditions. Many communities of plants and animals that are part of these threatened ecosystems have a limited ability to disperse to more amenable habitats.  While climate change may make some sites uninhabitable for a given community, it…
