Urbanization negatively impacts frog diversity at continental, regional, and local scales
Published: 2021-05-25
Subjects: Biodiversity, Life Sciences
Urban environments are novel ecosystems, with increased chemical, sound, and light pollution differentially impacting many animals. Understanding the impacts of urban environments on biodiversity is the first step to understanding how to best mitigate biodiversity losses in an increasingly urbanizing world. Analyses with broad geographic and taxonomic coverage can offer critical context for [...]
Understanding plant microbiomes requires a G x E framework

Subjects: Biodiversity, Botany, Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Microbiology, Plant Breeding and Genetics Life Sciences, Plant Sciences, Terrestrial and Aquatic Ecology
Plant microbiomes have become one of the hottest topics in plant biology. Driven by the increased availability of metagenome sequencing methods, analyses of plant-associated microbiomes have been skyrocketing during the last decade. They have generally taken one of two main perspectives: (1) a focus on the microbiome itself, where researchers describe microbiome diversity and attempt to [...]
Species’ traits drive amphibian tolerance to anthropogenic habitat modification
Published: 2021-05-05
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Anthropogenic habitat modification is accelerating, threatening the world’s biodiversity. Understanding species’ responses to anthropogenic modification is vital for halting species’ declines. However, this information is lacking for globally threatened amphibians, informed primarily by small community-level studies. We integrated >126,000 verified citizen science observations of frogs, with a [...]
Quantifying the checks and balances of decentralised governance systems for adaptive carnivore management
Published: 2021-05-05
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Population Biology
1. Recovering or threatened carnivore populations are often harvested to minimise their impact on human activities, such as livestock farming or game hunting. Increasingly, harvest quota decisions involve a set of scientific, administrative and political institutions operating at national and sub-national levels whose interactions and collective decision-making aim to increase the legitimacy of [...]
The economic value of fisheries, blue carbon, and nutrient cycling in global marine forests
Published: 2021-04-29
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Underwater kelp forests have provided valuable ecosystem services for millennia. However, the global economic value of those services is largely unresolved. Kelp forests are also diminishing globally and efforts to manage these valuable resources are hindered without accurate estimates of the services kelp forests provide to society. We present the first global economic estimation of services - [...]
Spillback in the Anthropocene: the risk of human-to-wildlife pathogen transmission for conservation and public health

The SARS-CoV-2 pandemic has led to increased concern over transmission of pathogens from humans to animals (“spillback”) and its potential to threaten conservation and public health. To assess this threat, we reviewed published evidence of spillback events, including instances where spillback could threaten conservation and human health. We identified 97 verified examples of spillback, involving [...]
BetaBayes - A Bayesian approach for comparing ecological communities
Published: 2021-04-08
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Physical Sciences and Mathematics, Statistics and Probability
Ecological communities change due to both natural and human factors. Distinguishing between the two is critical to ecology and conservation science. One of the most common approaches for modelling species composition changes is calculating Beta diversity indices and then relating index changes to covariates changes. The main difficulty with these analyses is that Beta diversity indices are paired [...]
Astatotilapia species (Teleostei, Cichlidae) from Malawi, Mozambique and Tanzania, excluding the basin of Lake Victoria.
Published: 2021-04-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The haplochromine cichlid fauna of the rivers and smaller lakes of Tanzania and SE Africa are of key importance in understanding the origins and inter-relationships of the great lake cichlid radiations of Malawi, Tanganyika and Victoria. Prior to formal taxonomic investigations, here we present the results of investigations of the type specimens, identification of type localities and superficial [...]
Forest Conservation in Madagascar: Past, Present, Future
Published: 2021-03-31
Subjects: Biodiversity, Life Sciences
To be published in the upcoming book The New Natural History of Madagascar, edited by S. M. Goodman, published by Princeton University Press. A French translation of the chapter "Conservation des forêts à Madagascar : Passé, Présent, et Futur" is included at the end of the preprint. At this critical time for the future of Madagascar’s biodiversity, we first review the past: touching upon [...]
Applying conservation reserve design strategies to define ecosystem monitoring priorities
Published: 2021-03-24
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
In an era of unprecedented ecological upheaval, accurately monitoring ecosystem change at large spatial scales and over long-time frames is an essential to effective environmental management and conservation. However, economic limitations often preclude revisiting entire monitoring networks at a high enough frequency to accurately detect ecological changes. Thus, a prioritisation strategy is [...]
Report of programming bugs in the DAISIE R package: consequences and correction
Published: 2021-03-24
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences
DAISIE (Dynamic Assembly of Islands through Speciation, Immigration and Extinction) is a framework for a dynamic stochastic model of island biogeography that can be used to estimate the rates of colonisation, speciation and extinction (CES rates) from phylogenetic trees of insular communities by maximum likelihood, and to simulate such data sets given a set of rates. The framework is available in [...]
Temporal Change Detection Analysis of Monroe County, NY tree cover from 2009 to 2017

Forests provide many ecosystem services which are enjoyed by nearby residing communities. This includes pollution and flood mitigation, carbon sequestration, oxygen production, food, fuel, education, recreation, and aesthetics. These ecosystem services also come from urban and suburban forests. Urban ecosystems, specifically urban green spaces services have been noted to improve human health [...]
Capitalizing on opportunistic citizen science data to monitor urban biodiversity: a multi-taxa framework
Published: 2021-03-09
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Monitoring urban biodiversity is increasingly important, given the increasing anthropogenic pressures on biodiversity in urban areas. While the cost of broad-scale monitoring by professionals may be prohibitive, citizen science (also referred to as community science) will likely play an important role in understanding biodiversity responses to urbanization into the future. Here, we present a [...]

The COVID-19 pandemic has brought biosecurity to the forefront of national security policy. Land use change is a fundamental driver of zoonotic disease outbreaks, yet substantial study is yet required to unravel the mechanisms by which land use-induced spillover operates. Ecological degradation may be the 21st Century’s most overlooked security threat. Within the biosecurity context, we introduce [...]

Evolutionary and organismal biology have become inundated with data. At the same rate, we are experiencing a surge in broader evolutionary and ecological syntheses for which tree-thinking is the staple for a variety of post-tree analyses. To fully take advantage of this wealth of data to discover and understand large-scale evolutionary and ecological patterns, computational data integration, i.e. [...]
