Impacts of biodiversity and biodiversity loss on zoonotic diseases [PDF]
Proceedings of the National Academy of Sciences, 2021 Zoonotic diseases are infectious diseases of humans caused by pathogens that are shared between humans and other vertebrate animals. Previously, pristine natural areas with high biodiversity were seen as likely sources of new zoonotic pathogens, suggesting that biodiversity could have negative impacts on human health. At the same time, biodiversity has

Geological Society, London, Special Publications, 2022 Abstract Non-living and living nature are inherently connected. Geodiversity, which consists of the variation in geology, soils, topography, geomorphology and hydrology, is seen as the foundation and stage for biodiversity. Underlying theory suggests that the increasing variation in the abiotic foundation creates and maintains available niche

Biodiversity Quality: a paradigm for biodiversity
Nature Precedings, 2009 AbstractThe internationally accepted definition of biodiversity creates difficulty in measuring difference and change. The authors suggest that well-sampled data can be used to generate a range of numerical indices reflecting species group characteristics/functionality (Species Richness, Simposons Index, Population Density, Biomass and Species ...

Butterflies in bags: permanent storage of Lepidoptera in glassine envelopes [PDF]
Nota Lepidopterologica, 2019 In terms of amateurs and professionals studying and collecting insects, Lepidoptera represent one of the most popular groups. It is this popularity, in combination with wings being routinely spread during mounting, which results in Lepidoptera often ...

Sharing taxonomic expertise between natural history collections using image recognition [PDF]
Research Ideas and Outcomes, 2022 Natural history collections play a vital role in biodiversity research and conservation by providing a window to the past. The usefulness of the vast amount of historical data depends on their quality, with correct taxonomic identifications being the ...

Palaeontology, 2012 Abstract: Palaeontologists have always had something to say about the origins of biodiversity. However, until recently, most of what they had to say was somewhat speculative. Following the inspirational suggestions by Simpson in the 1940s, the American ‘paleobiological revolution’ of the 1970s encouraged palaeontologists to think numerically and in ...

Parasite, 2008 As many others parasites, speciation of flukes depends on the genetic characteristics and on ploidia. Ploidia of flukes can be different in a same species. In Asia, diploid, triploid and hybrid (2n/3n) populations are encountered. The comparison of morphological parameters between diploid and triploid flukes showed that they were morphologically ...

Biodiversity loss underlies the dilution effect of biodiversity [PDF]
Ecology Letters, 2020 AbstractThe dilution effect predicts increasing biodiversity to reduce the risk of infection, but the generality of this effect remains unresolved. Because biodiversity loss generates predictable changes in host community competence, we hypothesized that biodiversity loss might drive the dilution effect.
