Revisiting Safe Biological Limits in Fisheries [PDF]
Fish and Fisheries, 2014 The appropriateness of three official fisheries management reference points used in the north-east Atlantic was investigated: (i) the smallest stock size that is still within safe biological limits (SSBpa), (ii) the maximum sustainable rate of ...

Limits on the evolutionary rates of biological traits
Scientific ReportsThis paper focuses on the maximum speed at which biological evolution can occur. I derive inequalities that limit the rate of evolutionary processes driven by natural selection, mutations, or genetic drift.

Exploring the Limits of Biological Complexity Amenable to Studies by Incoherent Neutron Spectroscopy
Life, 2022 The wavelengths of neutrons available at neutron scattering facilities are comparable with intra- and inter-molecular distances, while their energies are comparable with molecular vibrational energies, making such neutrons highly suitable for studies of ...

Biological Carbon Sequestration and Carbon Trading Re-Visited [PDF]
, 2009 Biological activities that sequester carbon create CO2 offset credits that could obviate the need for reductions in fossil fuel use. Credits are earned by storing carbon in terrestrial ecosystems and wood products, although CO2 emissions are also ...

Optical Biosensors and Their Applications for the Detection of Water Pollutants
Biosensors, 2023 The correct detection and quantification of pollutants in water is key to regulating their presence in the environment. Biosensors offer several advantages, such as minimal sample preparation, short measurement times, high specificity and sensibility and

Informational limits of biological organisms [PDF]
The EMBO Journal, 2018 Genomic analyses have revealed that free‐living biological organisms carry between 10 7 and 10 11 bits of information in their genomes. In large organisms with relatively small population sizes, such as humans, only in the order of 1% of the genomic information is shaped by the environment via natural selection.

Planar Airy beam light-sheet for two-photon microscopy [PDF]
, 2020 We demonstrate the first planar Airy light-sheet microscope. Fluorescence light-sheet microscopy has become the method of choice to study large biological samples with cellular or sub-cellular resolution. The propagation-invariant Airy beam enables a ten-

On the Limitations of Biological Knowledge [PDF]
Current Genomics, 2012 Scientific knowledge is grounded in a particular epistemology and, owing to the requirements of that epistemology, possesses limitations. Some limitations are intrinsic, in the sense that they depend inherently on the nature of scientific knowledge; others are contingent, depending on the present state of knowledge, including technology.

Grazing limits natural biological controls of woody encroachment in Inner Mongolia Steppe
Biology Open, 2017 Woody encroachment in grasslands has become increasingly problematic globally. Grazing by domestic animals can facilitate woody encroachment by reducing competition from herbaceous plants and fire frequency.
