Ovarian Histology and Expression of Related Candidate Genes in High- and Low-Fecundity Populations of Penaeus vannamei

open access: yesProgress in Fishery Sciences
The Pacific white shrimp Penaeus vannamei is one of the most productive shrimp species in China and the world. Domestic demand for P. vannamei has increased annually because of its fast growth, easy breeding, strong resistance to stress and disease, and ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Comparative analysis of fecundity in close amphimictic Aporrectodea сaliginosa and apomictic A. trapezoides earthworms, and the problem of reproductive advantages of parthenogenetic animals.

open access: yesZoodiversity, 2020
The comparative analysis of fecundity and fertility was studied experimentally for the amphimictic Aporrectodea caliginosa diploid earthworms and the close parthenogenetic A. trapezoides triploid earthworms during two seasons. The individual fecundity of

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Advances in methods for determining fecundity: application of the new methods to some marine fishes [PDF]

open access: yes, 2009
Estimation of individual egg production (realized fecundity) is a key step either to understand the stock and recruit relationship or to carry out fisheries-independent assessment of spawning stock biomass using egg production methods.
