Records of rat control campaigns in a food market with the largest seafood trading volume worldwide

Yasushi Kiyokawa, ryoko koizumi, Ryoko Yamada, et al.

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 [...]

Alternative seafood networks during COVID-19: Implications for resilience and sustainability

Joshua S. Stoll, Hannah L. Harrison, Emily De Sousa, et al.

Published: 2020-09-14
Subjects: Social and Behavioral Sciences

Export-oriented seafood trade faltered during the early months of the COVID-19 pandemic. In contrast, alternative seafood networks (ASNs) that distribute seafood through local and direct marketing challenges were identified as a “bright spot”. In this paper, we draw on multiple lines of quantitative and qualitative evidence to show that ASNs experienced a temporary pandemic “bump” in both the [...]

Meta-analysis reveals an extreme “decline effect” in the impacts of ocean acidification on fish behaviour

Jeff Clements, Josefin Sundin, Timothy D Clark, et al.

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 [...]

BERTERO’S GHOST REVISITED: NEW TYPIFICATIONS OF TALINUM LINARIA COLLA AND CALANDRINIA GAUDICHAUDII BARNÉOUD (= CALANDRINIA PILOSIUSCULA DC; MONTIACEAE)

Mark Alan Hershkovitz

Published: 2020-09-08
Subjects: Biodiversity, Life Sciences

In a revision of the systematics of Calandrinia pilosiuscula DC (including Calandrinia compressa Schrad. ex DC; Montiaceae), Hershkovitz recognized a total of ten validly named synonyms, including Calandrinia gaudichaudii Barnéoud and Talinum linaria Colla. He concluded that these two names were homotypic, both protologs citing a Bertero collection from Valparaiso, which Hershkovitz inferred to [...]

Recent advances of quantitative modeling to support invasive species eradication on islands

Christopher Baker, Michael Bode

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

Kenta Uchida, Rachel V. Blakey, Joseph Robert Burger, et al.

Published: 2020-09-07
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

Noah Fierer, Stephen A Wood, Clifton P. Bueno de Mesquita

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

Chelsea J. Little, Matteo Rizzuto, Thomas M. Luhring, et al.

Published: 2020-08-31
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

Jeffrey James Thompson, Ronaldo Morato, Bernardo Brandão Niebuhr, et al.

Published: 2020-08-31
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 [...]

Beekeeping in, of, or for the city? A socioecological perspective on urban apiculture

Douglas B Sponsler, Eve Z. Bratman

Published: 2020-08-31
Subjects: Agriculture, Entomology, Environmental Studies, Life Sciences, Social and Behavioral Sciences, Urban Studies and Planning

The term “urban beekeeping” has come to connote a host meanings --- sociopolitical, commercial, ecological, personal --- beyond the mere description of where bees and beekeepers happen to coincide. Yet these meanings are seldom articulated explicitly and seldom brought into critical engagement with the relevant fields of urban ecology and political ecology. Beginning with a brief account of the [...]

Removing the bad apples: a simple bioinformatic method to improve loci-recovery in de novo RADseq data for non-model organisms

José Cerca, Marius F. Maurstad, Nicolas Rochette, et al.

Published: 2020-08-30
Subjects: Bioinformatics, Computational Biology, Genetics and Genomics, Genomics, Life Sciences

The restriction site-associated DNA (RADseq) family of protocols involves digesting DNA and sequencing the region flanking the cut site, thus providing a cost and time efficient way for obtaining thousands of genomic markers. However, when working with non-model taxa with few genomic resources, optimization of RADseq wet-lab and bioinformatic tools may be challenging, often resulting in allele [...]

VIRUS-HOST RELATIONSHIPS: AN OVERVIEW

Mustafa Adhab

Published: 2020-08-30
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 [...]

Cultural inheritance is driving a major transition in human evolution

Timothy Waring, Zachary Wood

Published: 2020-08-23
Subjects: Social and Behavioral Sciences

An evolutionary transition in individuality (ETI) is the emergence of a new level of biological complexity, such as multicellular life or eusocial insects. There is disagreement on the degree to which the human species is undergoing such a transition. Here, we advance a theory of long-term human evolution in which a transition in individuality is driven by an underlying transition in inheritance [...]

Unifying individual differences in personality, predictability, and plasticity: a practical guide

Rose E O'Dea, Daniel W.A. Noble, Shinichi Nakagawa

Published: 2020-08-22
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])

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 [...]
