Nature-based solutions (NbS), including blue carbon ecosystems, are crucial to meeting Net-Zero targets. The UK’s Net-Zero 2050 strategy, alongside terrestrial measures, prioritises large-scale offshore wind development, creating opportunities to integrate marine NbS into Net-Zero plans. Consequently, aligning…

We evaluate episodes of biosphere change throughout Earth history and compare them with contemporary and near-future anthropogenic changes, developing the concept of biosphere disruptors – agents that force global-scale macroevolutionary change. Transient disruptors are geologically short-lived agents (mean 8.0×10^5^…

Climate warming and forest fragmentation threaten tropical biodiversity by altering microclimates and narrowing the range of temperatures within which species can maintain optimal physiological performance. We investigated the thermoregulatory capacities of five forest-dependent bird species from the Taita Hills…

A central goal of biogeography is to partition the world’s biota into meaningful biogeographical regions. While naturalists have long delineated biogeographic regions using hierarchical hard clustering approaches, they have often acknowledged the existence of transition zones. However, such transition zones have not…

The present-day martian surface is generally considered inhospitable to life because of low atmospheric pressure, intense surface radiation, global desiccation, and oxidizing chemistry which has been increasing since the late Noachian. However, shallow martian subsurface regions where mineralogy has shown groundwater…

Phytoplankton are primarily confined to the sunlit epipelagic zone, yet intact algal cells persist in the ocean’s mesopelagic twilight zone where light is minimal. However, their survival strategies in the deeper ocean remain unknown. Here, we isolate Chaetoceros sp. DS1 from 1000 m depth and reveal its survival…

Climate change threatens livestock-dependent livelihoods across sub-Saharan Africa, yet National Adaptation Programmes of Action (NAPAs) and Nationally Determined Contributions (NDCs) rarely incorporate animal genetic resource management despite explicit mandates under the Convention on Biological Diversity’s Global…

Directional selection is often viewed as a transient force in macroevolution, with its signal eroded over time by stabilizing and fluctuating selection. Yet, transitions into new adaptive zones are predicted to impose strong and sustained selective pressures that may leave a detectable signature even across deep…

The biological carbon pump (BCP) transports carbon fixed by phytoplankton into the deep ocean via multiple pathways and leads to net carbon dioxide sequestration. The BCP is very active in highly productive eastern boundary upwelling systems (EBUSs), however, the extent to which climate change will impact this key…

Microbial diversity across ecosystems may be impacted by dispersal pathways and selection due to physiochemical conditions, and so it is hard to predict the extent of strain sharing across heterogeneous environmental compartments. Evaluation of patterns of strain-level overlap requires genome-level comparisons using…
