Integrating metabolic scaling and coexistence theories. [PDF]

Ecology
Abstract Metabolic scaling theory has been pivotal in formalizing the expected energy expenditures across populations as a function of body size. Coexistence theory has provided a mathematization of the environmental conditions compatible with multispecies coexistence.

NetworkExtinction: An R package to simulate extinction propagation and rewiring potential in ecological networks

Methods in Ecology and Evolution, Volume 14, Issue 8, Page 1952-1966, August 2023., 2023
Abstract Earth's biosphere is undergoing drastic reorganization due to the sixth mass extinction brought on by the Anthropocene. Impacts of local and regional extirpation of species have been demonstrated to propagate through the complex interaction networks they are part of, leading to secondary extinctions and exacerbating biodiversity loss ...

The importance of cryptic diversity in the conservation of wide‐ranging species: The red‐footed tortoise Chelonoidis carbonarius in Colombia

Molecular Ecology, Volume 32, Issue 16, Page 4531-4545, August 2023., 2023
Abstract Wide‐ranging species are seldom considered conservation priorities, yet they have the potential to harbour genetically deeply differentiated units across environments or ecological barriers, including some that warrant taxonomic recognition. Documenting such cryptic genetic diversity is especially important for wide‐ranging species that are in

Global‐Krigger: A Global Kriging Interpolation Toolbox With Paleoclimatology Examples

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 6, June 2023., 2023
Abstract Many applications in Earth sciences require spatial prediction, that is, obtaining a continuous scalar field from a set of discrete scalar data points on the Earth's surface. Such applications include model‐data comparisons and derivation of continuous scalar fields as input for Earth system models. The advantage of kriging as an interpolation

Occupancy–detection models with museum specimen data: Promise and pitfalls

Methods in Ecology and Evolution, Volume 14, Issue 2, Page 402-414, February 2023., 2023
Abstract Historical museum records provide potentially useful data for identifying drivers of change in species occupancy. However, because museum records are typically obtained via many collection methods, methodological developments are needed to enable robust inferences.

Persistence and size of seasonal populations on a consumer–resource relationship depends on the allocation strategy toward life-history functions

Scientific Reports, 2020
The long-term ecological dynamics of a population inhabiting a seasonal environment is analyzed using a semi-discrete or impulsive system to represent the consumer–resource interaction.
