title: From rhetoric to reality: which resilience, why resilience, and whose resilience in spatial planning?

authors: White, Iain

subjects: Science & Technology

abstract: This paper analyses contrasting academic understandings of ‘equilibrium resilience’ and ‘evolutionary resilience’ and investigates how these nuances are reflected within both policy and practice. We reveal that there is a lack of clarity in policy, where these differences are not acknowledged with resilience mainly discussed as a singular, vague, but optimistic aim. This opaque political treatment of the term and the lack of guidance has affected practice by privileging an equilibrist interpretation over more transformative, evolutionary measures. In short, resilience within spatial planning is characterised by a simple return to normality that is more analogous with planning norms, engineered responses, dominant interests, and technomanagerial trends. The paper argues that, although presented as a possible paradigm shift, resilience policy and practice underpin existing behaviour and normalise risk. It leaves unaddressed wider sociocultural concerns and instead emerges as a narrow, regressive, technorational frame centred on reactive measures at the building scale.

title: Adaptation to environmental temperature in divergent clades of the nematode Pristionchus pacificus

authors: Leaver, Mark

subjects: adaptation

abstract: Because of ongoing climate change, populations of organisms are being subjected to stressful temperatures more often. This is especially problematic for ectothermic organisms, which are likely to be more sensitive to changes in temperature. Therefore, we need to know if ectotherms have adapted to environmental temperature and, if so, what are the evolutionary mechanisms behind such adaptation. Here, we use the nematode Pristionchus pacificus as a case study to investigate thermal adaptation on the Indian Ocean island of La Réunion, which experiences a range of temperatures from coast to summit. We study the evolution of high-temperature tolerance by constructing a phylogenetic tree of strains collected from many different thermal niches. We show that populations of P. pacificus at low altitudes have higher fertility at warmer temperatures. Most likely, this phenotype has arisen recently and at least twice independently, consistent with parallel evolution. We also studied low-temperature tolerance and showed that populations from high altitudes have increased their fertility at cooler temperatures. Together, these data indicate that P. pacificus strains on La Réunion are subject to divergent selection, adapting to hot and cold niches at the coast and summit of the volcano. Precisely defining these thermal niches provides essential information for models that predict the impact of future climate change on these populations.

authors: Tuaupiki, Jackie Whetumarama

abstract: Mai anō ngā terenga waka a te Māori, ko ōna kōrero tuku iho i whakatauira tuatahingia e ngā atua tonu, taka mai ki te iwi tāngata o Te Moana-nui-a-Kiwa. Tā tēnei tuhinga, he wānanga i te mana o te kōrero tuku iho e haupū nei ngā pūrākau terenga waka onamata i takoto ai te tūāpapa mātauranga whakatere mō ngā waka tūpuna i heke iho i Hawaiki ki Aotearoa. Nō reira, ka riariakina ngā pūtoi whakatauiratanga waka a te Māori i ōna atua me ōna tūpuna me te ahunga mai o ana terenga mātāmua, ka aromātai hoki i te takiwā o ngā tau i tauria ai e ōna takere Te Ika-a-Māui e takoto nei.
