The spatial and temporal variability of phytoplankton blooms was investigated in two tropical coastal regions of northern Australia using the MEdium Resolution Imaging Spectrometer (MERIS) full mission (2002–2012) reduced resolution dataset. Satellite-derived proxies for phytoplankton (Chlorophyll-a (Chl), Fluorescence Line Height (FLH), Maximum Chlorophyll Index (MCI)) and suspended sediment (...

This paper identifies fundamental issues which prevent the effective uptake of climate information services in Nigeria. We propose solutions involve extension short-range (1 to 5 days) forecasts beyond that medium-range (7 15 timescales through operational use current forecast data as well improve collaboration and communication with users. Using newly available provide seamless from short-term...

Recently, in the Auerswald et al. (2015) comment on "Rainfall erosivity in Europe", 5 criticisms were addressed: i) the neglect of seasonal erosion indices, ii) the neglect of published studies and data, iii) the low temporal resolution of the data, especially of the maximum rain intensity, iv) the use of precipitation data instead of rain data and the subsequent deviation of the R-factor in Ge...

Reproductive success usually declines in the course of the season, which may be a direct effect of breeding time, an effect of quality (individuals with high phenotypic or environmental quality breeding early), or a combination of the two. Being able to distinguish between these possibilities is crucial when trying to understand individual variation in annual routines, for instance when to bree...

As we start a new school year I would like to take this opportunity to welcome back the many students, staff, research associates and faculty associated with the Center for the Integrative Study of Animal Behavior (CISAB). To those of you who are new to CISAB and the Indiana University community, I would like to extend a special welcome to you and I would also like to express my excitement abou...

The South China Sea is one of the most important fishing grounds in China and is also a traditional fishing ground. In order to determine the primary productivity products suitable for various traditional fishing areas, this paper is based on three models of VGPM, Eppley-VGPM and CbPM, we estimate the primary and the average monthly data of marine primary productivity in 8 days, a detailed anal...

[1] With the discovery by the Cassini spacecraft of an oxygen atmosphere over Saturn’s main rings, and a strong source of water products from the plumes of Saturn’s moon Enceladus, our picture of the physics of Saturn’s magnetosphere from the main rings to inside the orbit of Enceladus has changed dramatically. This region contains oxygen ions from the ring atmosphere and water-group ions from ...

due to the importance of the import management, this study applies generalized ardl approach to estimate midas regression for wheat import value and to compare the accuracy of forecasts with those competed by the regression with adjusted data model. mixed frequency sampling models aim to extract information with high frequency indicators so that independent variables with lower frequencies are ...

We study the attack rate, that is the total fraction of the population infected each year, for a disease with seasonally varying transmission rate. The attack rate is shown to be governed by both the reproductive number, reflecting the transmissibility of the disease, and the birth rate, which provides a source of new susceptibles. For the case of epidemics which have an annual period (like the...

Prior studies on the association between weather and psychological changes have produced mixed results. In part, this inconsistency may be because weather's psychological effects are moderated by two important factors: the season and time spent outside. In two correlational studies and an experiment manipulating participants' time outdoors (total N = 605), pleasant weather (higher temperature o...
