Immunologic Profiling of the Atlantic Salmon Gill by Single Nuclei Transcriptomics

open access: yesFrontiers in Immunology, 2021
Anadromous salmonids begin life adapted to the freshwater environments of their natal streams before a developmental transition, known as smoltification, transforms them into marine-adapted fish.

Variation in responses to photoperiods and temperatures in Japanese medaka from different latitudes

open access: yesZoological Letters, 2023
Seasonal changes are more robust and dynamic at higher latitudes than at lower latitudes, and animals sense seasonal changes in the environment and alter their physiology and behavior to better adapt to harsh winter conditions. However, the genetic basis

The seasonality of conception [PDF]

open access: yesDemography, 2007
AbstractIndividual data on menstrual cycles of noncontracepting women living in Western countries were used in order to verify whether the biological seasonality of conception persists after sexual behavior is controlled for. Episodes of intercourse were recorded daily, and the time of ovulation was detected by a marker. We find that the seasonality of

A method for using monthly average temperatures in phenology models for grapevine (Vitis vinifera L.)

open access: yesOENO One, 2022
In recent years, there have been increasing efforts to link phenology models with seasonal climate predictions in so-called Decision Support Systems (DSS) to tailor crop management strategies. However, temporal discrepancies between phenology models with

On the Role of Seasonal Intercepts in Seasonal Cointegration [PDF]

open access: yesOxford Bulletin of Economics and Statistics, 1999
In the paper we consider the role of seasonal intercepts in seasonal cointegration analysis. For the nonseasonal unit root, such intercepts can generate a stochastic trend with a drift common to all observations. For the seasonal unit roots, however, we show that unrestricted seasonal intercepts generate trends that are different across the seasons ...

Sampling, Filtering, and Analysis Protocols to Detect Black Carbon, Organic Carbon, and Total Carbon in Seasonal Surface Snow in an Urban Background and Arctic Finland (>60° N)

open access: yesAtmosphere, 2020
Black carbon (BC), organic carbon (OC), and total carbon (TC) in snow are important for their climatic and cryospheric effects. They are also part of the global carbon cycle.
