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 [...]
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 [...]
Variation in regrowth ability in relation to land use intensity and predictability in three common grassland herbs
Published: 2020-06-26
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: 2020-06-23
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 [...]
Phylogeny can Inform Animal Model Development for Both Inherited and Induced Conditions: Duchenne’s Muscular Dystrophy (DMD) and Fetal Alcohol Spectrum Disorders (FASD)
Published: 2020-06-09
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 [...]
A guide to using the Internet to monitor and quantify the wildlife trade
Published: 2020-05-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Other Life Sciences
The unrivalled growth in e-commerce of animals and plants presents an unprecedented opportunity to monitor wildlife trade to inform conservation, biosecurity, and law enforcement. Using the Internet to quantify the scale of the wildlife trade (volume, frequency) is a relatively recent and rapidly developing approach, which currently lacks an accessible framework for locating relevant websites and [...]
Crowdsourcing global perspectives in ecology using social media
Published: 2020-05-13
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Transparent, open, and reproducible research is still far from routine, and the full potential of open science has not yet been realized. Crowdsourcing––defined as the usage of a flexible open call to a heterogeneous group of individuals to recruit volunteers for a task ––is an emerging scientific model that encourages larger and more outwardly transparent collaborations. While crowdsourcing, [...]
Assessing Raspberry Shake and Boom sensors for recording African elephant acoustic vocalizations

Subjects: Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Other Animal Sciences, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences
In this work we assess the performance of the Raspberry Shake and Boom (RS&B) sensor package for detecting and monitoring African elephants (Loxodonta africana). This is the first documented test of this particular unit for recording animal behaviour; the unit was originally designed for detecting tectonic earthquakes and low frequency (<50 Hz) atmospheric acoustics. During a four day [...]
Predicting tropical tree mortality with leaf spectroscopy

Subjects: Ecology and Evolutionary Biology, Forest Biology, Forest Sciences, Life Sciences, Other Ecology and Evolutionary Biology, Other Plant Sciences, Plant Sciences
Do tropical trees close to death have a distinct leaf spectral signature? Tree mortality rates have been increasing in tropical forests globally which is reducing the global carbon sink. Upcoming hyperspectral satellites could be used to predict regions close to experiencing extensive tree mortality during periods of stress like drought. Here we show how imminent tropical tree mortality in [...]
Rapidly mapping fire effects on biodiversity at a large-scale using citizen science

Pre-maturation social experience affects female reproductive strategies and offspring fitness in a highly polyandrous insect
Published: 2020-03-17
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology
The pre-maturation social environment experienced by females may affect their post-maturation reproductive strategies, including mating preferences and investment in offspring. Whether the pre-maturation social environment also affects other aspects of females’ reproductive strategies, such as the degree of polyandry and post-copulatory decisions, is still an open question. To address this [...]
