Fitness of evolving bacterial populations is contingent on deep and shallow history but only shallow history creates predictable patterns

Timothy Cooper, Francisco Moore, Chelsea Smith & Adam Smith
Long term evolution experiments have tested the importance of genetic and environmental factors in influencing evolutionary outcomes. Differences in phylogenetic history, recent adaptation to distinct environments, and chance events all influence the fitness of a population. However, the interplay of these factors on a population's evolutionary potential remains relatively unexplored. We tracked the outcome of 2,000 generations of evolution of four natural isolates of Escherichia coli bacteria that were engineered to also create differences in...

Climate change and alpine-adapted insects: modelling environmental envelopes of a grasshopper radiation

Emily Koot, Mary Morgan-Richards & Steven Trewick
Mountains create steep environmental gradients that are sensitive barometers of climate change. We modelled the environmental envelopes of twelve predominantly alpine, flightless grasshopper species in Aotearoa New Zealand, using current conditions and two future global climate change scenarios: representative concentration pathway (RCP) 2.6 (1.0 °C raise) and RCP8.5 (3.7 °C raise). Two thirds of our models suggested a reduced potential range across species by 2070, but surprisingly, for six species we predict an increase in...

Present and future distribution of bat hosts of sarbecoviruses: implications for conservation and public health

Renata Lara Muylaert, Tigga Kingston, Jinhong Luo, Maurício Humberto Vancine, Nikolas Galli, Colin Carlson, Reju Sam John, Maria Cristina Rulli & David Hayman
Global changes in response to human encroachment into natural habitats and carbon emissions are driving the biodiversity extinction crisis and increasing disease emergence risk. Host distributions are one critical component to identify areas at risk of viral spillover, and bats act as reservoirs of diverse viruses. We developed a reproducible ecological niche modelling pipeline for bat hosts of SARS-like viruses (subgenus Sarbecovirus), given that several closely-related viruses have been discovered and sarbecovirus-host interactions have gained...

Predicting harvest impact and establishment success when translocating highly mobile and endangered species

Johannes Fischer, Heiko Wittmer, Caio Kenup, Kevin Parker, Rosalind Cole, Igor Debski, Graeme Taylor, John Ewen & Doug Armstrong
Harvesting individuals for translocations can negatively impact source populations, a critical challenge for species reduced to small populations. Consequently, translocation cohorts often remain small, reducing the establishment probability at the destination. Balancing the potential benefits and risks of such translocations is further complicated by philopatry and natural metapopulation dynamics if the target species is highly mobile. These challenges highlight the importance of translocation feasibility assessments, but such assessments often remain qualitative to date. The critically...

Efeito do leite proveniente de vacas A2A2, biofortificado ou não, na dieta de crianças com o Transtorno do Espectro do Autismo

Marta Vasconcelos
O leite contendo a variante A1 da β-caseína está associado a liberação do peptídeo bioativo β-Casomorfina-7 (BCM-7), em quantidades suficientes para desencadear potenciais efeitos adversos no sistema gastrointestinal, sobre a modulação de respostas pró-inflamatórias que podem resultar em sintomas de desconfortos. Sendo assim, vários estudos mencionam a possibilidade desses potenciais efeitos adversos serem restritos a uma pequena parcela da população, incluindo crianças com o Transtorno do Espectro do Autismo (TEA), mas esse tema ainda é...

High functional diversity in deep-sea fish communities and increasing intra-specific trait variation with increasing latitude

Elisabeth Myers, Marti Anderson, Libby Liggins, Euan Harvey, Clive Roberts & David Eme
Variation in both inter- and intra-specific traits affect community dynamics, yet we know little regarding the relative importance of external environmental filters vs internal biotic interactions that shape the functional space of communities along broad-scale environmental gradients, such as latitude, elevation or depth. We examined changes in several key aspects of functional alpha-diversity for marine fishes along depth and latitude gradients by quantifying intra- and inter-specific richness, dispersion and regularity in functional trait space. We...

Global flyway evolution in red knots Calidris canutus and genetic evidence for a Nearctic refugium

Jesse Conklin, Yvonne Verkuil, Phil Battley, Chris Hassell, Job Ten Horn, James Johnson, Pavel Tomkovich, Allan Baker, Theunis Piersma & Michaël Fontaine
Present-day ecology and population structure are the legacies of past climate and habitat perturbations, and this is particularly true for species that are widely distributed at high latitudes. The red knot, Calidris canutus, is an arctic-breeding, long-distance migratory shorebird with six recognized subspecies defined by differences in morphology, migration behavior, and annual-cycle phenology, in a global distribution thought to have arisen just since the Last Glacial Maximum (LGM). We used nextRAD sequencing of 10,881 single-nucleotide...

Ash leachate characteristics of the 27 April 2016 and 13 September 2016 eruptions of Whakaari/White Island volcano

Carol Stewart, Geoff N. Kilgour & Michael D. Rosenberg
Volcanic ash samples from the 27 April 2016 and 13 September 2016 eruptions of Whakaari / White Island volcano were collected on-island within 24 hours of each eruption. Water-extractable concentrations of a range of elements were determined in these samples, following the International Volcanic Health Hazard Network (IVHHN) protocol. These results are reported here to add to the broader geochemical data series for Whakaari / White Island and because of interest in the 2016 ash...
