Spatial bias in the GBIF database and its effect on modeling species' geographic distributions

TLDR
A subsampling routine is used as an exemplar taxon to provide evidence that range model quality is decreasing due to the spatial clustering of distributional records in GBIF and shows that data with less spatial bias produce better predictive models even though they are based on less input data.

Invasive alien insects represent a clear but variable threat to biodiversity

David A. Clarke, +1 more
- 17 Jun 2022 - 
TL;DR: Invasive alien insects as a driver of biodiversity change are an important yet understudied component of the general threat of biological invasions, with evidence to suggest that an insect species global maximum impact is likely to increase in severity as it increases its non-native distribution as mentioned in this paper .

On the distribution of the rare solitary bee Coelioxys lanceolata Nylander, 1852 (Hymenoptera, Megachilidae) in Norway

TL;DR: The relative uncommonness of C. lanceolata compared to other bee species may be due to sampling biases, and a sampling scheme that would allow assessing if such bias is influencing knowledge of the status of Norwegian bees is suggested.

Ecological Niche models using MaxEnt in Google Earth engine: Evaluation, guidelines and recommendations

TL;DR: In this article , the authors present the first MaxEnt models in GEE, as well as its first statistical and spatial evaluation, and they also identify the limitations of the approach, providing guidelines and recommendations for its easier applicability in Google Earth Engine (GEE).

Potential Climate-Driven Impacts on the Distribution of Generalist Treefrogs in

TL;DR: In this article, the authors evaluated the potential spatial effects that climate change might exert on four wide-ranging generalist anurans from South America and found that these treefrog species are predicted to experience a contraction in their geographical ranges at magnitudes varying from 13.90% to 52.06% due to the loss of suitable areas.

Extensive protected area coverage and an updated global population estimate for the Endangered Madagascar Serpent-eagle Eutriorchis astur

TL;DR: In this paper , the authors used SDMs correlating occurrences with remote-sensing covariates to calculate a first estimate of AOH for the Endangered Madagascar Serpent-eagle Eutriorchis astur, and then updated additional IUCN range metrics and the current global population estimate.

Maximum entropy modeling of species geographic distributions

TL;DR: In this paper, the use of the maximum entropy method (Maxent) for modeling species geographic distributions with presence-only data was introduced, which is a general-purpose machine learning method with a simple and precise mathematical formulation.

Modeling of species distributions with Maxent: new extensions and a comprehensive evaluation

TL;DR: This paper presents a tuning method that uses presence-only data for parameter tuning, and introduces several concepts that improve the predictive accuracy and running time of Maxent and describes a new logistic output format that gives an estimate of probability of presence.

Species Distribution Models: Ecological Explanation and Prediction Across Space and Time

TL;DR: Species distribution models (SDMs) as mentioned in this paper are numerical tools that combine observations of species occurrence or abundance with environmental estimates, and are used to gain ecological and evolutionary insights and to predict distributions across landscapes, sometimes requiring extrapolation in space and time.

AUC: a misleading measure of the performance of predictive distribution models

TL;DR: The area under the receiver operating characteristic (ROC) curve, known as the AUC, is currently considered to be the standard method to assess the accuracy of predictive distribution models as discussed by the authors.
