1. Simulation models are valuable tools for estimating ecosystem structure and function under various climatic and environmental conditions and disturbance regimes, and are particularly relevant for investigating the potential impacts of climate change on ecosystems. However, because computational requirements can restrict the number of feasible simulations, they are often run at coarse scales or [...]

BetaBayes - A Bayesian approach for comparing ecological communities

Filipe S. Dias, Michael Betancourt, Patricia María Rodríguez-González, et al.

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 [...]

Latin America and the Caribbean (LAC) contain more tropical high-biodiversity forest than the remaining areas of the planet combined, yet experienced more than a third of global deforestation during the first decade of the 21st century. While drivers of forest change occur at multiple scales, we examined forest change at the municipal and national scales integrated with global processes such as [...]

Oropendola nest predation and rodent consumption by the black-capped capuchin (Sapajus apella) in the Manu Biosphere Reserve, Peru

Subjects: Environmental Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics

The Neotropical primate Sapajus apella (Linnaeus, 1758), the black-capped capuchin monkey, is widely distributed across the Amazon basin (Boubli et al., 2020). Capuchins are generalist platyrrhines, occurring in most tropical forest types, where they forage opportunistically (Sabbatini et al., 2008; Lynch Alfaro et al., 2012; Boubli et al., 2020). They exploit a diverse variety of food sources, [...]

Global maps of soil temperature

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids thus fail to reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions are controlled and most terrestrial species reside. Here we provide global maps of soil [...]

Human social organization during the Late Pleistocene: Beyond the nomadic-egalitarian model

Many researchers assume that until 10-12,000 years ago, humans lived in small, mobile, relatively egalitarian bands composed mostly of kin. This “nomadic-egalitarian model” informs evolutionary explanations of behavior and our understanding of how contemporary societies differ from those of our evolutionary past. Here, we synthesize research challenging this model and propose an alternative, the [...]

Phyloreferences: Tree-Native, Reproducible, and Machine-Interpretable Taxon Concepts

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. [...]

The Terrestrial Ecosystem Research Network (TERN), Australia’s national land ecosystem monitoring program, measures critical environmental attributes from local to continental scale and generates quality data for research and land management. Since 2011, TERN has performed standardised field surveys and sampling across a national plot network. At each plot, TERN records vegetation structure, [...]

Phylogenetic multilevel meta-analysis: A simulation study on the importance of modeling the phylogeny

1. Meta-analyses in ecology and evolution require special attention due to certain study characteristics in these fields. First, the primary articles in these fields usually report results that are observed from studies conducted with different species, and the phylogeny among the species violates the independence assumption. Second, articles frequently allow the computation of multiple effect [...]

Synergistic impacts of anthropogenic fires and aridity on plant diversity in the Western Ghats: Implications for management of ancient social-ecological systems

Charuta Kulkarni, Walter Finsinger, Pallavi Anand, et al.

Published: 2020-10-01
Subjects: Biodiversity, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics, Sustainability

Identifying the impacts of anthropogenic fires on biodiversity is imperative for human-influenced tropical rainforests because: i) these ecosystems have been transformed by human-induced fires for millennia; and ii) their effective management is essential for protecting the world’s terrestrial biodiversity in the face of global environmental change. While several short-term studies elucidate the [...]

The eradication of invasive species from islands is an important part of managing these ecologically unique and at-risk regions. Island eradications are complex projects and mathematical models play an important role in supporting efficient and transparent decision-making. In this review we cover the past applications of modelling to island eradications, which range from large-scale [...]

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 [...]
