This article shows, using R software, how to seasonally adjust a time series using the X-13-ARIMA-SEATS program and the seasonal package developed by Christoph Sax. In addition to presenting step-by-step seasonal adjustment, ...

We examine the effects of seasonal adjustment filters on the size and power of ADF and PP residual-based cointegration tests via a Monte Carlo and an empirical application. Our results indicate that the use of filters ...

The influences of several management practices, as pruning, girdling, chemical and manual thinning on apple fruit size and yield efficiency, are known. Basically, yield improvement is achieved by a successful management ...

As ectotherms, amphibians may exhibit changes in their thermal biology associated with spatial and temporal environmental contingencies. However, our knowledge on how amphibian´s thermal biology responds to seasonal changes ...

This study was designed to determine the manner in which metabolism is suppressed during dormancy in black and white tegu lizards (Tupinambis merianae). To this end, heart rate (f (H)), respiration rate (f (R)), and deep ...

Environmental adjustment is the most invoked explanation for intra-seasonal variation in bird nest morphology. However, time constraints may also be important, coming as a trade-off between the costs of nest building and ...

Morpho-functional adjustments in the heart of juvenile tegu lizards (Tupinambis merianae) were analyzed at distinct seasonal periods to investigate how the demands of growth and of energy saving are reconciled during the ...

Although seasonal metabolic variation in ectothermic tetrapods has been investigated primarily in the context of species showing some level of metabolic depression during winter, but several species of anurans maintain ...
