Reconstructing Ecological Niche Evolution When Niches Are Incompletely Characterized [PDF]

open access: yesSystematic Biology, 2017
Evolutionary dynamics of abiotic ecological niches across phylogenetic history can shed light on large-scale biogeographic patterns, macroevolutionary rate shifts, and the relative ability of lineages to respond to global change. An unresolved question is how best to represent and reconstruct evolution of these complex traits at coarse spatial scales ...

Evaluating Potential Distribution and Niche Divergence among Populations of the World’s Largest Living Damselfly, Megaloprepus caerulatus (Drury, 1782)

open access: yesDiversity, 2022
Megaloprepus caerulatus is a Neotropical species with a highly specialised niche, found from Mexico to Bolivia, primarily in mature tropical forests lower than 1500 masl. It is also the damselfly with the largest wingspan in the world.

Human behavioral ecology and niche construction [PDF]

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, 2021
AbstractWe examine the relationship between niche construction theory (NCT) and human behavioral ecology (HBE), two branches of evolutionary science that are important sources of theory in archeology. We distinguish between formal models of niche construction as an evolutionary process, and uses of niche construction to refer to a kind of human ...

The role of ecological niche evolution on diversification patterns of birds distinctly distributed between the Amazonia and Atlantic rainforests.

open access: yesPLoS ONE, 2020
The Amazonian and Atlantic Forest share several organisms that are currently isolated but were continuously distributed during the Quaternary period. As both biomes are under different climatic regimes, paleoclimatic events may have modulated species ...

Specific habitat requirements and niche conservatism for nine species of the Mexican genus Thelocactus (Cactaceae)

open access: yesRevista Mexicana de Biodiversidad, 2019
Although Mexican Cactaceae are a significative component of Mexican flora and have a relevant economic and ornamental value, the knowledge of the environmental factors characterizing their niche is still rather limited.

Niche occupation limits adaptive radiation in experimental microcosms. [PDF]

open access: yesPLoS ONE, 2007
Adaptive radiations have played a key role in the evolution of biological diversity. The breadth of adaptive radiation in an invading lineage is likely to be influenced by the availability of ecological niches, which will be determined to some extent by ...

The Ecological Niche [PDF]

open access: yesNature, 1946
A SUPERB example illustrating the ecological niche is afforded by the distribution of the plankton copepod Limnocalanus macrurus, a freshwater relict derived from the marine arctic species L. Grimaldii. The animal has an upper temperature limit of 14° C, and a lower limit of dissolved oxygen of 4 c.c./l. oxygen.

Genecological aspects of air pollution effects on northern forests.

open access: yesSilva Fennica, 1981
Natural forest tree populations are adapted to their natural environment. Forest tree species under northern conditions are at the edge of their range where the short growing season and the low winter temperatures are the two main factors limiting their ...
