Impacts of Species Misidentification on Species Distribution Modeling with Presence-Only Data
Spatial records of species are commonly misidentified, which can change the predicted distribution of a species obtained from a species distribution model (SDM). Experiments were undertaken to predict the distribution of real and simulated species using MaxEnt and presence-only data contaminated with varying rates of misidentification error. Additionally, the difference between the niche of t...
متن کاملLogistic methods for resource selection functions and presence-only species distribution models
In order to better protect and conserve biodiversity, ecologists are making increasing use of machine learning and statistical modeling to understand how species respond to their environment and to predict how they will respond to future climate change, habitat loss and other threats. A fundamental modeling task is to estimate the conditional probability that a given species is present in (or u...

متن کاملPresence-absence versus abundance data for monitoring threatened species.
Effective detection of population trend is crucial for managing threatened species. Little theory exists, however, to assist managers in choosing the most cost-effective monitoring techniques for diagnosing trend. We present a framework for determining the optimal monitoring strategy by simulating a manager collecting data on a declining species, the Chestnut-rumped Hylacola (Hylacola pyrrhopyg...
متن کاملSample selection bias and presence-only distribution models: implications for background and pseudo-absence data.
Most methods for modeling species distributions from occurrence records require additional data representing the range of environmental conditions in the modeled region. These data, called background or pseudo-absence data, are usually drawn at random from the entire region, whereas occurrence collection is often spatially biased toward easily accessed areas. Since the spatial bias generally re...
