LABORATORY OBSERVATIONS ON LOCUST RESPONSES TO WIND‐BORNE GRASS ODOUR

Physiological and Antioxidative Responses of a Halophytic Grass Leptochloa fusca L. Kunth (Kallar grass) to Salinity

The effects of salt stress on growth and some physiological parameters of halophytic plant, Leptochloa fusca L. Kunth, were investigated. The seedlings were irrigated with half-strength Hoagland solution and then treated with different concentrations of NaCl (0, 100, 300, 500 and 700 mM) for 15 days. The fresh and dry weights of both root and shoot were unchanged at 100 mM NaCl and decreased at...

Responses of foraging hedgehogs to badger odour

Enclosure and field trials were used to investigate the responses of hedgehogs, Erinaceus europaeus, to predator (badger,Meles meles) and non-predator odours. Two hypotheses were tested: (1) hedgehogs are capable of responding to badger odour; and (2) hedgehogs prefer not to forage in areas tainted with badger odour. In enclosure trials, hedgehogs almost exclusively avoided feeding at sites tai...

Radar observations of locust swarms.

The locust jump: an integrated laboratory investigation.

The locust is well known for its ability to jump large distances to avoid predation. This class sets out a series of investigations into the mechanisms underlying the jump enabling students to bring together information from biomechanics, muscle physiology, and anatomy. The nature of the investigation allows it to be undertaken at a number of levels of complexity from relatively simple comparat...
