Product Information

EvidenceHayward (1994) states that seawater temperatures vary little between day and night, and seasonal variations tend to be slow and gradual, allowing animals to respond through behavioural changes. However, at low tide air temperature becomes critically important to intertidal animals, and on sandy beaches the habitat, from the surface to a depth of several centimetres, can experience large variations in temperature during a single tidal cycle (Hayward, 1994). For instance, Khayrallah & Jones (1978b) reported the temperature range of sand at a depth of 1 cm during neap tide periods, to be from -2°C in February 1973 to a maximum of 25°C in July 1977, but freezing of sediment was only encountered once in the three year period of study. The effect of an unusually cold winter on the interstitial fauna is a simple physical one, in which body fluids freeze, causing cell and tissue damage. However, whilst low temperature are likely to be physically damaging to interstitial animals, Crisp (1964) reported that other interstitial species of amphipod and isopods seemed to be unharmed by the severe winter of 1962-1963 and intolerance has been assessed to be low.

Evidence Bathyporeia pelagica is an infaunal species whose feeding is not reliant upon a supply of suspended material. A reduced concentration of suspended matter may be indicative of an alteration of shore topography, resulting in the reduced deposition of material and habitat loss for the species. However, for the period of one month effects are not likely to be significant, and intolerance has been assessed to be low. The species is likely to have an immediate capacity for recovery and re-population (see additional information, below).Watkin, E.E., 1939(a). The swimming and burrowing habits of some species of the amphipod genus Bathyporeia. Journal of the Marine Biological Association of the United Kingdom, 23, 457-465. For intertidal species or communities, the range of temperatures includes the air temperature regime for that species or community. Further details A short-term, acute change; e.g., a change of two categories from the MNCR salinity scale for one week ( view glossary) such as from full to reduced.

Editor's Note (September 2023): This product review was originally written and published in 2020. To make sure we are still recommending the best products for your needs, we recently reviewed this story to make sure it is still accurate and that we stand by what we wrote. Despite newer models and options being available, we still feel confident that this product is one of the best choices, and therefore have included it in The Best Toys for 3-Year-Olds, The Best Toy Cars, and The Best Snow Toys . Benchmark. Sensitivity can only be assessed relative to a known, named disease, likely to cause partial loss of a species population or community. Further details. The weight limit of The Big Dig Sandbox Digger is 110 pounds. This means that our kids will be able to use this toy for years before they get too heavy for the seat. We expect that they will outgrow it based on their height and how comfortable they can be on the seat before reaching the weight limit. Khayrallah, N.H., 1977.
