Accounting for year effects and sampling error in temporal analyses of population and biodiversity change - Response to Seibold et al. 2019 “Arthropod decline in grasslands and forests is associated with landscape-level drivers”
Published: 2020-10-11
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Population Biology
An accumulating number of studies are reporting severe biomass, abundance and/or species richness declines of insects (Hallmann et al., 2017; Lister & Garcia, 2018; Seibold et al., 2019; Sánchez-Bayo & Wyckhuys, 2019). Collectively these studies aim to quantify the net change in invertebrate populations and/or community composition over time and to establish whether such changes can be [...]
Impacts of human disturbance in marine mammals: Do behavioral changes translate to disease consequences? Full methods and Analysis
Published: 2020-10-01
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Population Biology
Humans have been altering wildlife habitats and wildlife behavior worldwide at an accelerated pace in recent decades. While it is well-understood how human-induced behavioral changes affect infectious disease risk in terrestrial wildlife, less is known in marine life. Here we examine this link in marine mammal populations by (1) conducting a systematic literature review to determine how human [...]
A call to action: Understanding land use-induced zoonotic spillover to protect environmental, animal, and human health

The rapid, global spread and human health impacts of SARS-CoV-2, the agent of COVID-19 disease, demonstrates humanity’s vulnerability to zoonotic disease pandemics. Although anthropogenic land use change is known to be the major driver of zoonotic pathogen spillover from wildlife to human populations, the scientific underpinnings of land use-induced zoonotic spillover have rarely been [...]
Sexual dichromatism, size dimorphism and microscale anatomy of white wing stripe in blue tit (Cyanistes caeruleus)
Published: 2020-09-25
Subjects: Biology, Life Sciences
Achromatic patches are a common element of plumage patterns in many bird species and there is growing body of evidence that in many avian taxa they can play a signaling role in mate choice. Although the blue tit is a well-established model species in the studies on colouration, its white wing patch has never been examined in the context of sex-specific trait expression. In this exploratory study, [...]
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 [...]
Testing character-evolution models in phylogenetic paleobiology: a case study with Cambrian echinoderms
Published: 2020-08-06
Subjects: Biodiversity, Biology, Life Sciences, Other Life Sciences
Macroevolutionary inference has historically been treated as a two-step process, involving the inference of a phylogenetic tree, and then inference of a macroevolutionary model using that tree. Newer models, such as the fossilized birth-death model, blend the two steps. These methods make more complete use of fossils than the previous generation of Bayesian phylogenetic models. They also involve [...]
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

Subjects: Biology, Life Sciences, Other Life 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 [...]
SYSTEMATICS OF CALANDRINIA PILOSIUSCULA DC A.K.A. CALANDRINIA COMPRESSA SCHRAD. EX DC (MONTIACEAE–MONTIOIDEAE)

Calandrinia compressa Schrad. ex DC (Prodr. 3: 359. 1828) is the name currently widely applied to a polymorphic annual species of Calandrinia sect. Calandrinia endemic to the Chilean Floristic Region. A total of ten validly published heterotypic names plus six horticultural designations (and orthographic variants thereof) have been considered at some point as taxonomically the same as C. [...]
Rapidly mapping fire effects on biodiversity at a large-scale using citizen science

The unprecedented scale of the 2019-2020 eastern Australian bushfires exemplifies the challenges that scientists and conservation biologists face monitoring the effects of biodiversity in the aftermath of large-scale environmental disturbances. After a large-scale disturbance there are conservation policy and management actions that need to be both timely and informed by data. By working with the [...]
Physiological condition of amphibians exposed to historical industrial pollution in a Brazilian biodiversity hotspot
Published: 2020-03-06
Subjects: Animal Sciences, Biodiversity, Biology, Life Sciences, Physiology
Industrial pollution is a significant global threat to biodiversity, but its consequences on rainforest ecosystems remains poorly understood. Amphibians are especially susceptible to pollutants released on natural environments due to their aquatic-terrestrial life cycle. Here, we explored the effects of severe historical air, water and soil industrial pollution of Cubatão Industrial Complex (São [...]
Sex- and context-specific associations between personality and a measure of fitness but no link with life history traits
Published: 2019-11-22
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences
The pace of life syndrome hypothesis posits that personality traits (i.e., consistent individual differences in behaviour) are linked to life history and fitness. Specifically, fast-paced individuals are predicted to be proactive (i.e., active and aggressive) with an earlier age at first reproduction, a shorter lifespan, and a higher fecundity than slow-paced individuals. Environmental conditions [...]
Non-avian reptile learning 40 years on: advances and promising new directions
Published: 2019-09-07
Subjects: Animal Sciences, Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences, Zoology
Recently, there has been a surge in cognition research using non-avian reptile systems. As a diverse group of animals, non-avian reptiles (turtles, the tuatara, crocodilians, and squamates - lizards, snakes and amphisbaenids) are good model systems for answering questions related to cognitive ecology; from the role of the environment in impacting brain, behaviour and learning, to how social and [...]
Experimentally altered rainfall regimes and host root traits affect grassland arbuscular mycorrhizal fungal communities
Published: 2019-07-30
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Microbiology, Plant Sciences, Terrestrial and Aquatic Ecology
Future climate scenarios predict changes in rainfall regimes. These changes are expected to affect plants via effects on the expression of root traits associated with water and nutrient uptake. Associated microorganisms may also respond to these new precipitation regimes, either directly in response to changes in the soil environment or indirectly in response to altered root trait expression. We [...]
Pet or pest? Stable isotope methods for the early detection of invasive alien species
Published: 2019-06-29
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
The illegal pet trade facilitates the global dispersal of invasive alien species (IAS), providing opportunities for new pests to establish in novel recipient environments. Despite the increasing threat of IAS to the environment and economy, biosecurity efforts often lack suitable, scientifically-based methods to make effective management decisions; such as identifying an established IAS [...]
