INTEGRATING PHYLOGENETICS AND ENVIRONMENTAL NICHE MODELS TO EXPLORE SPECIATION MECHANISMS IN DENDROBATID FROGS [PDF]
Evolution, 2004 We developed an approach that combines distribution data, environmental geographic information system layers, environmental niche models, and phylogenetic information to investigate speciation processes. We used Ecuadorian frogs of the family Dendrobatidae to illustrate our methodology.

Global Ecology and Biogeography, 2022 AbstractAimSpatial sampling biases in biodiversity data arise because of complex interactions between geography, species characteristics and human behaviour, including preferences for or against particular species or habitats; biases are therefore not necessarily independent of the environmental niches of species.

BMC Evolutionary Biology, 2018 Background Commercial whaling caused extensive demographic declines in many great whale species, including gray whales that were extirpated from the Atlantic Ocean and dramatically reduced in the Pacific Ocean.

Reduction of Genetic Variation When Far From the Niche Centroid: Prediction for Mangrove Species
Frontiers in Conservation Science, 2022 The niche-centroid hypothesis states that populations that are distributed near the centroid of the species' ecological niche will have higher fitness-related attributes, such as population abundance and genetic diversity than populations near the edges ...

To what degree are philosophy and the ecological niche concept necessary in the ecological theory and conservation? [PDF]
, 2017 Ecology as a field produces philosophical anxiety, largely because it differs in scientific structure from classical physics. The hypothetical deductive models of classical physics are simple and predictive; general ecological models are ...

Nature Communications, 2019 In the lead-up to the Cretaceous/Paleogene mass extinction, dinosaur diversity is argued to have been either in long-term decline, or thriving until their sudden demise. The latest Cretaceous (Campanian–Maastrichtian [83–66 Ma]) of North America provides

Anthropogenic impacts drive niche and conservation metrics of a cryptic rattlesnake on the Colorado Plateau of western North America [PDF]
Royal Society Open Science, 2016 Ecosystems transition quickly in the Anthropocene, whereas biodiversity adapts more slowly. Here we simulated a shifting woodland ecosystem on the Colorado Plateau of western North America by using as its proxy over space and time the fundamental niche ...

The ecological adaptation of the unparalleled plastome character evolution in slipper orchids
Frontiers in Plant Science, 2022 Plastomes may have undergone adaptive evolution in the process of plant adaptation to diverse environments, whereby species may differ in plastome characters.
