For most of us, mushrooms are the most familiar type of fungi, but not all fungi produce mushrooms. Of the estimated 5 million species of fungi, about 14,000 produce mushrooms. New Zealand has a fascinating mix of native, endemic and introduced fungi. With a bit of practice, patience, and a sharp eye, these species are only a foray away.

The strange parasitic plant genus Rafflesia faces a number of conservation challenges, including habitat loss, degradation, and fragmentation. Learning more about these rare species is a crucial step in informing the conservation management of Rafflesia.

Happy Arachtober, the month of spiders! Dr Fiona Cross, or "Doctor Spider", introduces us to some cute jumping spiders commonly found in New Zealand.

One of my favourite groups of New Zealand plants are our native conifers. Most people don’t realise that we have 21 described species and two undescribed species. These are spread across ten genera in three of the six global conifer families. And on a land area basis we have far more native species than the UK or...

Invertebrate life in New Zealand’s rivers and streamsWe all know about the kiwi and the kākāpō, but what iconic species are lurking beneath the surface of our rivers and streams?Freshwater invertebrates (animals without a backbone) are amazingly diverse: from taonga species such as kākahi (freshwater mussels) and kōura (crayfish), to...

The Southern Ocean south of the Antarctic Polar Front is managed by an international agreement analogous to the Antarctic Treaty, the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR).  This area accounts for 10% of the world’s oceans and includes some of the most pristine marine habitats on Earth. CCAMLR allows fishing but aims to balance conservation with rational...

Currently, there is considerable interest around the impacts that agriculture is having on water quality. Nationwide the focus has been on highlighting the issues but little attention has been paid to what the solutions might be.The Canterbury Waterway Rehabilitation Experiment (CAREX)* is a stream restoration project that has focused on finding solutions. CAREX has been...

Seaweed form one of the most diverse and productive ecosystems on this planet, yet, with most of its beauty hidden below the surface; its importance often slips our attention.Destruction of terrestrial forests often causes global sensation and outcries. We know about their importance as they provide a home and food sources for animals and their indispensable role for our...

Emperor penguins depend on sea ice for their survival. Arek Aspinwall describes the impact of global warming on this sensitive Antarctic habitat.

Public science communication is fundamental to science today. I believe that as scientists we have a duty to communicate our research to the public. Mainly because the public must be able to understand the basics of science to make informed decisions – perhaps the most vivid example of the negative consequences of insufficient communication by scientists and/or...
