Harnessing macrogenomics to study changing marine ecosystems under global climate change

Abstract Climate change is reshaping marine ecosystems at an accelerating pace. Predicting its impacts on biodiversity and ecosystem functions is therefore crucial to developing effective conservation strategies. Integration of genomic tools, habitat modelling and simulations off...

Biotic and abiotic drivers of ecosystem functioning differ between a temperate and a tropical region

Any single ecosystem will provide many ecosystem functions. Yet, we lack large‐scale, systematic studies of how abiotic factors can directly or indirectly – via effects on biodiversity – drive ecosystem functioning. In this study, we assessed the impact of climate, landscape and...

Fluid and metal provenance of the Kiskamavaara Cu-Co deposit, northern Norrbotten, Sweden

Abstract Kiskamavaara is a shear zone-hosted cobaltian pyrite and chalcopyrite deposit in Northern Norrbotten, Sweden. Although previously classified as an Iron Oxide Copper-Gold (IOCG) deposit, the dominance of pyrite is atypical, suggesting either an unusual IOCG variant or a d...

Architectural traits constrain the evolution of unisexual flowers and sexual segregation within inflorescences: an interspecific approach

ABSTRACT Male and female unisexual flowers have repeatedly evolved from the ancestral bisexual flowers in different lineages of flowering plants. This sex specialization in different flowers often occurs within inflorescences. We hypothesize that inflorescence architecture may im...

Global proliferation of opportunistic pleuromeian lycopsids following the disappearance of the end-Triassic forests

Abstract Environmental crises and mass extinction events on land are typically followed by ecological upheaval, during which opportunistic plants rapidly colonize devastated landscapes, forming transient ‘pioneer’ communities that precede the establishment of complex forest ecosy...

Quaternary Arctic planktonic foraminifera: morphological differentiation and taxonomic reassessment of subpolar spinose taxa

Abstract. Planktonic foraminifera in the modern Arctic Ocean are dominated by the non-spinose polar species Neogloboquadrina pachyderma. Acmes of two spinose, presumed subpolar taxa in Quaternary central Arctic sediment cores are therefore anomalous, implying significantly differ...
