Cushion plants act as facilitators for soil microarthropods in high alpine Sweden
Published: 2020-09-25
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Population Biology, Terrestrial and Aquatic Ecology
1. Cushion plants can have positive impacts on plant richness in severe environments and possibly across trophic levels on arthropods, an under-studied topic. 2. This study examined whether soil communities under cushions of Silene acaulis and Diapensia lapponica have higher richness and abundance of soil microarthropods (Acari, Collembola) than adjacent non-cushion vegetation; and whether [...]
Püllomen: an ethnoecological perspective of the Mapuche protector spirit insect
Published: 2020-09-17
Subjects: Anthropology, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Anthropology, Social and Behavioral Sciences
Biodiversity plays an important role in cultural worldviews, influencing myths, stories, and spiritual beliefs of indigenous peoples. This short review explores an ecological phenomenon that may have influenced and contributed to the development of the Mapuche good spirit insect (Püllomen), which represents the spirit of someone who passed away and comes back to the world of the living providing [...]
Changes in plant composition and diversity in an Alpine heath and meadow after 18 years of experimental warming
Published: 2020-09-17
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Background and aim Global warming is expected to have large impacts on high alpine and Arctic ecosystems in future. Here we report the effects of 18 years of experimental warming on two contrasting high alpine plant communities in subarctic Sweden. Methods Using open-top chambers (OTCs), we analysed the effects of long-term passive experimental warming on two high alpine plant communities, a [...]
Records of rat control campaigns in a food market with the largest seafood trading volume worldwide
Published: 2020-09-14
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
Brown rats (Rattus norvegicus) and roof rats (Rattus rattus) are among the most common mammals worldwide. Little is known about the effects of season on rat population size, which is important for understanding rat ecology and/or performing effective rat control campaigns. Tsukiji Market was a metropolitan central wholesale market in Tokyo and was located within 1 km from one of the biggest [...]
Meta-analysis reveals an extreme “decline effect” in the impacts of ocean acidification on fish behaviour
Published: 2020-09-14
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Ocean acidification – decreasing oceanic pH resulting from the uptake of excess atmospheric CO2 – has the potential to affect marine life in the future. Among the possible consequences, a series of studies on coral reef fishes suggested that the direct effects of acidification on fish behaviour may be extreme and have broad ecological ramifications. Recent studies documenting a lack of effect of [...]
Recent advances of quantitative modeling to support invasive species eradication on islands
Published: 2020-09-08
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics
The eradication of invasive species from islands is an important part of managing these ecologically unique and at-risk regions. Island eradications are complex projects and mathematical models play an important role in supporting efficient and transparent decision-making. In this review we cover the past applications of modelling to island eradications, which range from large-scale [...]
Urban biodiversity and the importance of scale
Published: 2020-09-08
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Many ecological and evolutionary processes are affected by urbanization, but cities vary by orders of magnitude in their human population size and areal extent. To quantify and manage urban biodiversity we must understand both how biodiversity scales with city size, and how ecological, evolutionary, and socioeconomic drivers of biodiversity scale with city size. We show how environmental abiotic [...]
How microbes can, and cannot, be used to assess soil health
Published: 2020-09-07
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Microbiology, Terrestrial and Aquatic Ecology
Healthy soils are critical to the health of ecosystems, economies, and human populations. Thus, it is widely acknowledged that soil health is important to quantify, both for assessment and as a tool to help guide management strategies. What is less clear is how soil health should actually be measured, especially considering that soil health is not exclusively a product of soil physical and [...]
Filling the Information Gap in Meta-Ecosystem Ecology
Published: 2020-09-01
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Fluxes of matter, energy, and information over space and time contribute to ecosystems’ functioning. The meta-ecosystem framework addresses the dynamics of ecosystems linked by these fluxes, however, to date, meta-ecosystem research focused solely on fluxes of energy and matter, neglecting information. This is problematic due to organisms’ varied responses to information, which influence local [...]
Range-wide factors shaping space use and movements by the Neotropic’s flagship predator: the jaguar
Published: 2020-09-01
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
The range-wide management of the jaguar (Panthera onca) depends upon maintaining core populations connected through multi-national, transboundary cooperation, which is dependent upon understanding the movement ecology and space use of jaguars throughout their range. Using 117 telemetry trajectories from 12 ecoregions, we examined the landscape-level environmental and anthropogenic factors related [...]
VIRUS-HOST RELATIONSHIPS: AN OVERVIEW
Published: 2020-08-31
Subjects: Agriculture, Ecology and Evolutionary Biology, Life Sciences, Microbiology, Other Ecology and Evolutionary Biology, Virology
In order to survive in nature, different pathogens follow different procedures to manipulate their host plants for the pathogen favor. Plant viruses are not an exception of this rule. They are often found to alter the host plant traits in the way that affects the community of organisms in the host plant as well as the vectoring insects. It has been indicated that virus-infected plants are more [...]
Unifying individual differences in personality, predictability, and plasticity: a practical guide
Published: 2020-08-23
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences
1. Many animal species show individual differences in behaviour that are partially consistent across repeated measurements. Commonly referred to as personality traits, differences in average behaviours are often correlated across individuals, forming ‘behavioural syndromes’ (e.g. individuals who are more aggressive are also bolder). 2. Generally, differences in the average behaviour of [...]
Investigating sex differences in genetic relatedness in great-tailed grackles in Tempe, Arizona to infer potential sex biases in dispersal (version 5 of this preprint has been peer-reviewed and recommended by Peer Community In Ecology [https://doi.org/10.24072/pci.ecology.100074])
Published: 2020-08-23
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
In most bird species, females disperse prior to their first breeding attempt, while males remain closer to the place they hatched for their entire lives. Explanations for such female bias in natal dispersal have focused on the resource-defense based monogamous mating system that is prevalent in most birds. In this system, males are argued to benefit from philopatry because knowing the local [...]
A systematic review of ecological responses to variation in seasonal snow cover
Published: 2020-08-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Seasonal snow is among the most important factors governing the ecology of many terrestrial ecosystems, but rising global temperatures are changing snow regimes and driving widespread declines in the depth and duration of snow cover. Loss of the insulating snow layer will fundamentally change the environment. Understanding how individuals, populations, and communities respond to different snow [...]
Differential effects of steroid hormones on levels of genetic variance in a wild bird: possible mechanism of maternal-effects x genetic variance interaction?
Published: 2020-08-20
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Genetic variation is one of the key concepts in evolutionary biology and an important prerequisite of evolutionary change. Still, we know very little about processes that modulate its levels in wild populations. In particular – we still are to understand why genetic variances often depend on environmental conditions. One of possible environment-sensitive modulators of observed levels of genetic [...]
