Simulation-based study design accuracy weights are not generalisable and can still lead to biased meta-analytic inference: Comments on Christie et al. 2019
Published: 2020-07-08
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Variable study quality is a challenge for all the empirical sciences, but perhaps particularly for disciplines such as ecology where experimentation is frequently hampered by system complexity, scale, and resourcing. The resulting heterogeneity, and the necessity of subsequently combining the results of different study designs, is a fundamental issue for evidence synthesis. We welcome the [...]
Conservation translocations of fauna in Aotearoa New Zealand: a review
Published: 2020-07-06
Subjects: Ecology and Evolutionary Biology, Life Sciences
There have been numerous declines and extinctions of native fauna in Aotearoa New Zealand since human settlement. Against this background of loss there have been remarkable advances in conservation management, including the use of conservation translocations to reduce extinction risk and restore depauperate ecosystems. Here, we review conservation translocations in Aotearoa New Zealand. Our [...]
Life in fluctuating environments
Published: 2020-07-04
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Variability in the environment defines the structure and dynamics of all living systems. Organisms have evolved traits and strategies that allow them to detect, exploit and predict the changing environment. Organisms maintain steady internal conditions required for physiological functioning through feedback mechanisms that allow internal conditions to remain at or near a set point despite a [...]
A review of contemporary Indigenous cultural fire management literature in southeast Australia
Published: 2020-07-04
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Indigenous cultural fire management is being recognised and revived across Australia, primarily in the centre and across the north. To explore the benefits of contemporary cultural fire management in southeast Australia and barriers to its revival, we undertook a systematic analysis of the literature. Seventy documented applications of cultural fire management projects were found with the [...]
Fossil Constraints on the Timescale of Parasitic Helminth Evolution
Published: 2020-06-30
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
The fossil record of parasitic helminths is often stated to be severely limited. Many studies have therefore used host constraints to constrain molecular divergence time estimates of helminths. Here we review direct fossil evidence for several of these parasitic lineages belong to various phyla (Acanthocephala, Annelida, Arthropoda, Nematoda, Nematomorpha, Pentastomida, Platyhelminthes). Our [...]
Timing and intensity of weather events shape nestling development strategies in three alpine breeding songbirds
Published: 2020-06-30
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Across taxa, offspring size traits are linked to survival, and life-time fitness. Inclement weather can be a major constraint on offspring growth and parental care. Despite the adaptive benefits of larger offspring, we have a limited understanding of the effects of severe environmental conditions across developmental stages and how coping strategies differ among species. We assessed the influence [...]
FIRED (Fire Events Delineation): An open, flexible algorithm & database of US fire events derived from the MODIS burned area product (2001-19)

Harnessing the fire data revolution, i.e., the abundance of information from satellites, government records, social media, and human health sources, now requires complex and challenging data integration approaches. Defining fire events is key to that effort. In order to understand the spatial and temporal characteristics of fire, or the classic fire regime concept, we need to critically define [...]
Ecosystem-based metrics provide better targets than explicit extinction targets for biodiversity frameworks
Published: 2020-06-26
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The post-2020 global biodiversity framework has the potential to shape the future of life on Earth, so great care must be taken in deciding its aims. The failure of all but one of the Aichi Targets requires a rethinking of prior agreements [1], and conservationists are now exploring new types of targets that are more likely to succeed. One commonly-suggested potential metric is extinction, with [...]
Variation in regrowth ability in relation to land use intensity and predictability in three common grassland herbs
Published: 2020-06-25
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Aims Plant populations in managed grasslands are subject to strong selection exerted by grazing, mowing and fertilization. Many previous studies showed that this can cause evolutionary changes in mean trait values, but little is known about the evolution of adaptive plant phenotypic plasticity in response to grassland management. Methods We conducted an outdoor common garden experiment to test [...]
Online conferences for better learning
Published: 2020-06-22
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Social and Behavioral Sciences
Conferences provide an invaluable set of opportunities for professional development. Online, virtual, and distributed conferences do not necessarily mean less opportunity for growth and innovation in science but varied and novel options for communicating the scientific process. Open science and many existing tools and structures are in place in the practice of contemporary ecology and evolution [...]
PRIORITY EFFECTS AND ECOLOGICAL RESTORATION
Published: 2020-06-18
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Priority effects refer to the order or timing of species arrival, including how species that arrive early to a site either positively or negatively affect establishment, growth, or reproduction of species that arrive later. Despite clear implications of priority effects on ecological restoration, to date there are no reviews of how and where priority effects have been studied and the extent to [...]
Husby, Reed & Visser - Demonstrating temperature induced phenological mismatch does not require negative effects on fitness or population growth: A comment on Samplonius et al.
Published: 2020-06-18
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
In a recent article Samplonius et al. (2020; preprint on EcoEvoRxiv, Version 1, Submitted 05, 2020 | Last edited: May 06, 2020) argue that there are “systematic weaknesses in the evidence for temperature mediated phenological mismatch”. While we appreciate their review of the literature on this topic and their call for a broadening of the taxonomic and geographic scope of mismatch research, their [...]
Potential effects of habitat fragmentation on wild animal welfare
Published: 2020-06-18
Subjects: Animal Sciences, Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences
The fragmentation of habitat has occurred throughout the history of life on Earth, but has been accelerated and magnified in scale over the past few centuries as a result of human industrial development. Habitat fragmentation affects the welfare of some wild animals directly, through the often violent processes that bring about fragmentation and by reducing the distance between them and the [...]
Do the ages of parents or helpers affect offspring fitness in a cooperatively breeding bird?
Published: 2020-06-16
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Age-related changes in either the phenotypes or genotypes of care-givers can impact juvenile performance. However, rarely in wild populations have germline and non-germline transgenerational effects of ageing been separately quantified. In cooperatively breeding animals, in addition to parental ages, the age of ‘helpers’ attending the nest may also impact juvenile performance. Using a wild [...]
Phylogeny can Inform Animal Model Development for Both Inherited and Induced Conditions: Duchenne’s Muscular Dystrophy (DMD) and Fetal Alcohol Spectrum Disorders (FASD)
Published: 2020-06-08
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
The use of animal models in research on human and veterinary diseases and disorders is retracting, though it is likely to remain critical for decades. In light of increasing regulation and expectations of judicious use of animal subjects, we examine the idea that the use of animal models can be guided by phylogenetic relationships and modern evolutionary and cladistic analyses. Given that [...]
