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 [...]
The ‘Holy Grail’ in Phylogenetic Reconstruction: Seeing the Forest for the Trees?
Published: 2019-06-18
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology
Systematic/macroevolutionary biology has dedicated much of the past 50 years of its energy and resources in an effort to resolve definitively the one true ‘tree of life’ and to explain materially its cause. But, no matter the quantity/quality of data, experimentation, and analysis, the effort is hampered by persistent and ever-accumulating contradictory observations. This may be an indication [...]
Accurate forest projections require long-term wood decay experiments because trait effects change.
Published: 2019-06-15
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Deadwood is a large aboveground carbon (C) pool that regulates how forests respond to global change. Due to slow decomposition, CWD delays C emissions following major forest disturbances so predicting how carbon balance will respond to changing disturbance regimes requires identifying factors that influence the full temporal trajectory of wood decay from senescence to complete mineralization. [...]
On the importance of the megabiota to the functioning of the biosphere
Published: 2019-06-15
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Natural Resources and Conservation, Other Ecology and Evolutionary Biology, Physical Sciences and Mathematics
A prominent signal of the Anthropocene is the extinction and population reduction of the megabiota – the largest animals and plants on the planet. However, we lack a predictive framework for the sensitivity of megabiota during times of rapid global change and how they impact the functioning of ecosystems and the biosphere. Here, we extend metabolic scaling theory and use global simulation models [...]
Into the wild: microbiome transplant studies need broader ecological reality
Published: 2019-05-08
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Gut microbial communities (microbiomes) profoundly shape the ecology and evolution of multicellular life. Interactions between host and microbiome appear to be reciprocal, and ecological theory is now being applied to better understand how hosts and their microbiome influence each other. However, some ecological processes that underlie reciprocal host-microbiome interactions may be obscured by [...]
Open Access Principles and Practices Benefit Conservation
Published: 2019-05-02
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Open access is often contentious in the scientific community, but its implications for conservation are under-discussed or omitted entirely from scientific discourse. Access to literature is a key factor impeding implementation of conservation research, and many open access models and concepts that are little-known by most conservation researchers may facilitate implementation. Conservation [...]
Forest management effects on survival of a long-lived bird
Published: 2019-04-29
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
1. A high number of reproductive events is a critical fitness correlate for long-lived species. Thus, individuals of these species should be sensitive to factors that increase their mortality. Living in habitats with high exposure to predators can decrease lifespan, but the ecological drivers of longevity within populations remain poorly studied. Forest management in boreal forests can increase [...]
Lack of definition of mathematical terms in ecology: The case of the sigmoid class of functions in macro-ecology
Published: 2019-04-12
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Defining mathematical terms and objects is a constant issue in ecology; often definitions are absent, erroneous, or imprecise. Through a bibliographic prospection, we show that this problem appears in macro-ecology (biogeography and community ecology) where the lack of definition for the sigmoid class of functions results in difficulties of interpretation and communication. In order to solve this [...]
Improving scientific impact: how to practice science that influences environmental policy and management
Published: 2019-03-29
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Scientists devote substantial time and resources to research intended to help solve environmental problems. Environmental managers and policymakers must decide how to use the best available research evidence to prioritize actions leading to desired environmental outcomes. Yet decision-makers can face barriers to using scientific evidence to inform action. They may be unaware of the evidence, lack [...]
Mapping and understanding the digital biodiversity knowledge about vertebrates in the Atlantic Rainforest
Published: 2019-03-18
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Biodiversity data are fundamental for macroecological studies. Recent efforts on gathering global data have not been sufficient to surpass biases and gaps. This incompleteness has serious consequences on conservation and ecological understanding, therefore it is of major importance to map, quantify and describe these flaws. In this paper we aimed to assess inventory incompleteness for the [...]
Climate, human disturbance and geometric constraints drive the elevational richness pattern of birds in a biodiversity hotspot in south-western China
Published: 2019-02-22
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
We explored the elevational richness patterns of birds in a biodiversity hotspot in south-western China, the Gaoligong Mountains and assessed the role of different spatial factors, climatic factors and landscape composition in shaping the richness patterns. The east slope of the southern part of Gaoligong Mountains (24.79°N-26.49°N, 98.65°E-98.93°E) is the western-most part of the Hengduan [...]
Dominance determines fish community biomass in a temperate seagrass ecosystem
Published: 2019-01-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Biodiversity and ecosystem function are often correlated, but there are multiple hypotheses about the mechanisms underlying this relationship. Ecosystem functions such as primary or secondary production may be maximized by species richness, evenness in species abundances, or the presence or dominance of species with certain traits. Here, we combined surveys of natural fish communities (conducted [...]
Early-life telomere length predicts survival to adulthood and lifespan in a wild mammal
Published: 2018-11-22
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Telomeres, protective caps at the end of chromosomes, maintain genomic stability and function as a biomarker of senescence in many vertebrate species. Telomere length at different ages has been related to (subsequent) lifespan, but to date only one laboratory-based study has shown a direct link between early-life telomere length and lifespan. Whether this relationship holds in wild populations, [...]
