Here, we first review the current shortcomings in assessing demographic feedbacks in population and community dynamics. Despite the importance of such demographic feedbacks, forecasts that account for them are limited as individual-based data on interacting species are perceived to be essential for such mechanistic forecasting-but are rarely available. Such effects can then be exacerbated when species interactions generate reciprocal feedbacks between the demographic rates of the different species. In resume, I recommand the HP PSC 1315 as a good quality printer/scanner for cramped spaces an occasional use.In structured populations, persistence under environmental change may be particularly threatened when abiotic factors simultaneously negatively affect survival and reproduction of several life cycle stages, as opposed to a single stage.

On a 2 GHz system, this don't make a difference, but on a 500 MHz system, it slows down the system by about 20%.Īs for the physical presentation, the PSC 1315 is a very compact device abd fairly robust. The other negative point is that HP All-in-one products tend to use much memory and CPU speed, constantly. But at least, the print heads are included in the ink cartridges.

Negative point: As for other HP products, the price of ink cartridges is expensive. I didn't use the direct photo transfer fu nction as such. Preview is fairly fast and color depth is more than sufficient.Īs a copier, the PSC 1315 offers a fast way of duplicating any documents, even color ones in the blink of an eye. I could go without printing for 3 months at a time and never had problems with dried ink.Īs for the scanner, quality is good on Windows 2000, but is better on Windows XP (they probably changed somethink in the drivers). Like all the HP products I used in the past, the ink rarely dries out in the cartrige. The inkjet printer is quiet, fast and possess many printing options such as 5 quality settings (draft to maximum) and multiple pages on one page / one page on multiple pages. The HP PSC 13xx line of inkjet All-in-one is a good choice for small offices and home use.
