Season does not have a deleterious effect on proportions of stallion seminal plasma proteins
The Journal of Reproduction and Development, 2020 The mechanism by which the content of the major groups of seminal plasma proteins in stallion semen changes between the breeding and non-breeding seasons remains unknown.

Analysing seasonal changes in New Zealand's largest inbound market [PDF]
, 2008 The purpose of the paper is to analyse seasonal changes in tourism demand by New Zealand's major tourist source market, Australia, for the period 1979-2005. A time series regression model is used to test the significance of monthly seasonality.

PRODUCTIVITY OF OKRA VARIETIES AS INFLUENCED BY SEASONAL CHANGES IN NORTHERN NIGERIA
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2007 In northern Nigeria, two distinct season are noticeable and these are the wet (April to October) and the dry (November to March) seasons. Due to little or no documented work conducted to investigate the influence of climatic changes on the performance of

Seasonal changes in mycophagous insect communities
European Journal of Entomology, 2022 The phenology of fungal fruiting has changed in the UK over the last 70 years, but whether the associated mycophagous insects are able to exploit 'out of season' fruit bodies is unknown.

Seasonality, density dependence and spatial population synchrony [PDF]
, 2022 Spatial population synchrony has been the focus of theoretical and empirical studies for decades, in the hopes of understanding mechanisms and interactions driving ecological dynamics. In many systems, it is well-known that seasonality plays a critical role in the density dependence structure of the populations, yet this has hardly received any ...

Changing seasonality of the Baltic Sea [PDF]
Biogeosciences, 2015 Abstract. Changes in the phenology of physical and ecological variables associated with climate change are likely to have significant effect on many aspects of the Baltic ecosystems. We apply a set of phenological indicators to multiple environmental variables measured by satellite sensors for 17–35 years to detect possible changes in the seasonality ...

Dynamic plasticity in phototransduction regulates seasonal changes in color perception
Nature Communications, 2017 To cope with seasonal changes in the environment, organisms adapt their physiology and behavior. Although color perception varies among seasons, the underlying molecular basis and its physiological significance remain unclear.

The effect of seasonal strength and abruptness on predator-prey dynamics [PDF]
, 2020 Coupled dynamical systems in ecology are known to respond to the seasonal forcing of their parameters with multiple dynamical behaviours, ranging from seasonal cycles to chaos. Seasonal forcing is predominantly modelled as a sine wave but the transition between seasons is often more sudden.

Average seasonal changes in chlorophyll a in Icelandic waters [PDF]
, 2009 The standard algorithms used to derive sea surface chlorophyll a concentration from remotely sensed ocean colour data are based almost entirely on the measurements of surface water samples collected in open sea (case 1) waters which cover ~60% of the ...
