Subjects: Anthropology, Archaeological Anthropology, Arts and Humanities, Biological and Physical Anthropology, History of Art, Architecture, and Archaeology, Other Arts and Humanities, Other Languages, Societies, and Cultures, Pacific Islands Languages and Societies, Social and Behavioral Sciences
Remodelling is a fundamental biological process involved in the maintenance of bone physiology and function. We know that a range of health and lifestyle factors can impact this process in living and past societies, but there is a notable gap in bone remodelling data for populations from the Pacific Islands. We conducted the first examination of femoral cortical histology in 69 individuals from [...]
Dirty Transmission Hypothesis: Increased Mutations During Horizontal Transmission Can Select for Increased Levels of Mutualism in Endosymbionts
Published: 2022-02-27
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
A mutualistic symbiosis occurs when organisms of different species cooperate closely for a net benefit over time. Mutualistic relationships are important for human health, food production, and ecosystem maintenance. However, they can evolve to parasitism or breakdown all together and the conditions that maintain and influence them are not completely understood. Vertical and horizontal [...]
Mountain Gorillas benefit from social distancing too: Close proximity from tourists affects gorillas sociality
Published: 2022-02-25
Subjects: Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Gorilla tourism supports the protection of the gorilla ecosystem, benefiting humans and wildlife populations living therein. Assessing to what degree the presence and proximity of tourists affect wildlife aids long-term benefits. Because wild animals might see human activities as stressors, we hypothesised that the increased presence and proximity of tourists leads to an immediate increase in [...]
How has bird biodiversity changed over time? A review across spatio-temporal scales
Published: 2022-02-25
Subjects: Biodiversity, Life Sciences
Empirical quantification of biodiversity changes remains a challenge even in well surveyed groups such as birds. This may be because the change depends on spatio-temporal scales, specifically on spatial grain (i.e. area of a sampling unit), geographic extent (i.e. size of the area of interest), temporal grain (i.e. duration of a sampling event), and temporal extent (i.e. length of the time [...]
Survival of the luckiest
Published: 2022-02-25
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Psychology, Social and Behavioral Sciences
Opposite dynamics are behind natural selection and sexual selection. While the fittest survives in natural selection, the survivor will most likely be the luckiest when both dynamics are combined.
Achieving global biodiversity goals by 2050 requires urgent and integrated actions
Published: 2022-02-25
Subjects: Agriculture, Animal Sciences, Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Genetics and Genomics, Life Sciences, Marine Biology, Plant Sciences
Human impacts on the Earth’s biosphere are driving the global biodiversity crisis. Governments are preparing to agree on a set of actions intended to halt the loss of biodiversity and put it on a path to recovery by 2050. We provide evidence that the proposed actions can bend the curve for biodiversity, but only if these actions are implemented urgently and in an integrated manner.
Acute blood parasite infections induce moderate physiological costs in juvenile raptor hosts
Published: 2022-02-24
Subjects: Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences, Other Ecology and Evolutionary Biology, Parasitology
Parasites trigger reactions in hosts, leading to suppressive resistance and/or tolerance, aiming to limit the parasitic costs. Both colonization by parasites and defense activation can induce varying amount of costs for the host. Understanding parasite-induced effects on host fitness crucially depends on assessing parasitic costs in specific wild host-parasite systems. To evaluate potential [...]
Soil biota impacts on plant access to different water pools in soil
Published: 2022-02-22
Subjects: Life Sciences, Other Life Sciences, Plant Sciences
Aims: Soil water availability depends on the capacity of soil pores to hold it via physical forces creating gradient of availability from tightly bound water to highly mobile water. Abiotic factors directly affect the size of these pools and plant access to them. Biotic factors influence plant-soil-water relations and possibly affect soil properties and plant access to different water pools. [...]
Portrayal of the nitrogen debate in Dutch newspapers
Published: 2022-02-21
Subjects: Communication, Environmental Studies, Social and Behavioral Sciences
How sustainability challenges are relayed to the public is paramount to tackling such issues timely. However, there is still a lot to learn about the communication system between sustainability experts and the public. We looked at how Dutch newspapers portrayed the Dutch nitrogen debate that has been going on since 2019. 160 articles from four Dutch national daily newspapers were analyzed for [...]
Evolution of social organization: phylogenetic analyses of ecology and sexual selection in weavers
Published: 2022-02-20
Subjects: Animal Studies, Social and Behavioral Sciences
Crook published a landmark study on the social organization of weavers (or weaverbirds, family Ploceidae) that contributed to the emergence of sociobiology, behavioral ecology, and phylogenetic comparative methods. By comparing ecology, spatial distribution, and mating systems, Crook suggested that the spatial distribution of food resources and breeding habitats influence weaver aggregation, both [...]
Systemic racism alters wildlife genetic diversity
Published: 2022-02-18
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Humans are the defining feature of urban ecosystems. In the United States, systemic racism has had lasting effects on the structure of cities, specifically due to government-mandated “redlining” policies that produced racially segregated neighborhoods that persist today. However, it is not known whether varying habitat structure and natural resource availability associated with racial segregation [...]
Drivers of community assembly change during succession in wood-decomposing insect communities
Published: 2022-02-18
Subjects: Biodiversity, Biology, Entomology, Life Sciences
1. The patterns of successional change of decomposer communities is unique in that resource availability predictably decreases as decomposition proceeds. Saproxylic (i.e., deadwood-dependent) beetles are a highly diverse and functionally important decomposer group, and their community composition is affected by both deadwood characteristics and other environmental factors. Understanding how [...]
Improving species conservation plans under IUCN’s One Plan Approach using quantitative genetic methods
Published: 2022-02-18
Subjects: Ecology and Evolutionary Biology, Genetics, Genetics and Genomics, Life Sciences
Human activities are resulting in altered environmental conditions that are impacting the demography and evolution of species globally. If we wish to prevent anthropogenic extinction and extirpation, we need to improve our ability to restore wild populations. Ex situ populations can be an important tool for species conservation. However, it is difficult to prevent deviations from an optimal [...]
Graph embedding and transfer learning can help predict potential species interaction networks despite data limitations
Published: 2022-02-18
Subjects: Biodiversity, Life Sciences
Metawebs (networks of potential interactions within a species pool) are a powerful abstraction to understand how large-scale species interaction networks are structured. Because metawebs are typically expressed at large spatial and taxonomic scales, assembling them is a tedious and costly process; predictive methods can help circumvent the limitations in data deficiencies, by providing a first [...]
