Predicting life history parameters for all fishes worldwide.

open access: yesEcological Applications, 2017
Scientists and resource managers need to know life history parameters (e.g., average mortality rate, individual growth rate, maximum length or mass, and timing of maturity) to understand and respond to risks to natural populations and ecosystems.

Convergent evolution in toothed whale cochleae

open access: yesBMC Evolutionary Biology, 2019
Background Odontocetes (toothed whales) are the most species-rich marine mammal lineage. The catalyst for their evolutionary success is echolocation - a form of biological sonar that uses high-frequency sound, produced in the forehead and ultimately ...

Life History Adaptations to Seasonality.

open access: yesIntegrative and Comparative Biology, 2017
Seasonality creates a template for many natural processes and evolutionary adaptations. Organisms are often faced with an annual cycle consisting of a productive (favorable) and unproductive period.

The Deep History of Life [PDF]

open access: yesThe Biomedical & Life Sciences Collection, 2012
The conventional fossil record is built of hard parts—bones, shells, and decay-resistant organic tissues buried in the sediments that accumulate on floodplains, in lakes, and on the seafloor. In the 1950s, geologists first began the routine application of radioactive decay to problems of geologic age.

Life History Theory and Evolutionary Psychology

open access: yes, 2015
In this chapter we present an overview of life history theory and review its main psychological applications. We first discuss basic trade-offs in life history allocations and introduce the concept of life history strategies.

Metabarcoding unsorted kick‐samples facilitates macroinvertebrate‐based biomonitoring with increased taxonomic resolution, while outperforming environmental DNA

open access: yesEnvironmental DNA, 2021
While previous studies have highlighted the potential of DNA‐based methods for the biomonitoring of freshwater macroinvertebrates, a limited number have investigated homogenization of bulk samples that include debris, in order to reduce sample‐processing
