MaxEnt versus MaxLike: empirical comparisons with ant species distributions
Ecosphere, 2013 MaxEnt is one of the most widely used tools in ecology, biogeography, and evolution for modeling and mapping species distributions using presence‐only occurrence records and associated environmental covariates.

Which Algorithms are Feasible? Maxent Approach
, 1998 It is well known that not all algorithms are feasible; whether an algorithm is feasible or not depends on how many computational steps this algorithm requires. The problem with the existing definitions of feasibility is that they are rather ad hoc. Our goal is to use the maximum entropy (MaxEnt) approach and get more motivated definitions.

Physiological Stresses Under Climate Change Drive Range Shifts in Small Ectotherms
Journal of Biogeography, EarlyView.ABSTRACT Aim Climate change is expected to impose severe physiological stress on ectotherms, potentially reshaping their geographic distributions. Many species are expected to be impacted by the detrimental effects of climate change on their homeostatic balance, with suitable habitat shifting to higher latitudes and elevations. However, little is known

A statistical explanation of MaxEnt for ecologists
, 2013 This presentation is loosely based on Elith et al.'s (2010) paper by the same name. It explains the rationale behind the MaxEnt approach to species distribution modeling with presence-only data in an intuitive way with some simple examples. It's worth noting that I initially wrote this presentation before the connections between MaxEnt and Poisson ...

Journal of Applied Entomology, EarlyView.ABSTRACT Spatial interpolation represents a fundamental approach in applied insect ecology, offering insight into species distributions and supporting biodiversity analysis, pest management and disease vector mapping. Insects—including important pollinators—face escalating threats due to habitat loss, climate change and anthropogenic pressures. As data‐

Information Across the Ecological Hierarchy
Entropy, 2019 The ecosystem is a theatre upon which is presented, in various degrees and at differing scales, a drama of constraint and information vs. disorganization and entropy. Concerning biology, most think immediately of genomic information.

Field validation of an invasive species Maxent model
Ecological Informatics, 2016 AbstractAccurate and reliable predictions of invasive species distributions are urgently needed by land managers for developing management plans and monitoring new potential areas of establishment. Presence-only species distribution models are commonly used in these evaluations, however they are rarely tested with independent data over time or compared

Molecular Ecology, EarlyView.ABSTRACT Population declines may have long‐term genetic consequences, including genetic erosion and inbreeding depression, which could affect species' evolutionary potential and increase their risk of extinction. Small populations are more vulnerable to genetic threats than common species, but even species with large populations can also be at risk of ...
