Short-term precipitation forecasting is essential for planning of human activities in multiple scales, ranging from individuals’ planning, urban management to flood prevention. Yet the short-term atmospheric dynamics are highly nonlinear that it cannot be easily captured with classical time series models. On other hand, deep learning models good at interactions, but they not designed deal seaso...

Prenatal and perinatal exposures vary seasonally (e.g., sunlight, allergens) and many diseases are linked with variance in exposure. Epidemiologists often measure these changes using birth month as a proxy for seasonal variance. Likewise, Genome-Wide Association Studies have associated or implicated these same diseases with many genes. Both disparate data types (epidemiological and genetic) can...

Winter is a particularly difficult time to breed and survive. Animals monitor day length (photoperiod) to engage seasonally appropriate adaptations in anticipation of harsh winter conditions. I propose that photoperiodic information, mediated by melatonin, might also influence immune responses. Individuals could improve survival if seasonally recurring stressors were anticipated and countered. ...

Most temperate songbird species sing seasonally, and the brain areas involved in producing song (the song system) vary in size alongside the changes in behavior. Black-capped chickadees (Poecile atricapillus) also sing seasonally, and we find that there are changes in the stereotypy and the length of the fee-bee song from the nonbreeding to the breeding season. Yet despite these changes, we fai...

The present study aimed to identify the mosquito vectors distributed throughout AL-Ahsaa district situated in the eastern region of Saudi Arabia. Mosquito larvae were collected seasonally for one year (October 2009 to September 2010) from different breeding sites in seven rural areas utilizing long aquatic nets. Salinity and pH of these breeding sites were also measured seasonally. The survey r...

Food storing is seasonal in birds like chickadees, nuthatches and jays, occurring at high levels in fall and winter and low levels in spring and summer. Memory for cache sites is hippocampus dependent in chickadees and both the recruitment of new neurons into the hippocampus and the total size of the hippocampus change seasonally. Unlike seasonal change in the vocal control nuclei of songbirds,...

Anostracan zoogeography, biogeography, and habitat preferences have predominately been studied as related to the water quality parameters of their seasonally astatic wetland habitats. However, since water quality in seasonally astatic wetlands can fluctuate dramatically over a range of time scales, water quality data are generally of limited usefulness. Anostracan taxa occurrences in each of th...
