title: Did primitive microorganisms use nonhem iron proteins in place of NAD/P?

authors: Daniel, Roy M.

subjects: archaebacteria

abstract: Nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) are of universal occurrence in living organisms and play a central role in coupling oxidative with reductive reactions. However, the evidence that the origin and early evolution of life occurred at high temperatures (>95°C) is now strong, and at these temperatures some modern metabolites, including both the reduced and oxidized forms of these coenzymes, are unstable. We believe there is good evidence that indicates that in the most primitive organisms nonhem iron proteins carried out many or all of the functions of NAD/P(H). This has important implications for the way in which investigations of archaebacterial metabolism are conducted.

title: Mitigating flood risks: analysis of different types and quantity of green infrastructure

authors: Reu Junqueira, Juliana

abstract: Climate change is likely to intensify the effects of extreme weather events and increase their impacts on urban areas. A major emerging challenge for urban areas is how to address these uncertainties without neglecting the need to manage development and population growth.

title: Gendered geographies of resistance, resilience and reworking in Aotearoa feminist geography scholarship

authors: Adams-Hutcheson, Gail

abstract: Aotearoa New Zealand feminist geographies involve alliances of connected and vibrant researchers who pay close attention to the politics of knowledge production, power, intersectionality and decolonisation. Safe spaces to speak and write together have been nurtured over time ‘down under’ due to a collective politics of care and mentoring. This special issue demonstrates the strength of collective thinking on resistance, resilience and reworking contemporary geographical practice in Aotearoa. The four empirically based and theoretically informed articles develop new thinking about resistance to colonialism, patriarchy, racism, metricisation and oppression. These critical articles contribute to feminist geographical knowledges both locally and globally.
