Ammophila

 

a genus of plants of the family Gramineae. The perennial grasses range in height from 0.5 to 1 m and have creeping rhizomes. The plants form a thick turf. The leaf blades are stenolinear. The inflorescence is a long and dense cylindrical panicle, and the spikelets are single-flowered and strongly laterally compressed. The glumes are stenolanceolate and keeled. The lemmas, which are leathery and have three to five ribs, are shorter than or the same length as the glumes.

There are two species of Ammophila, distributed in Europe, North Africa, and eastern North America. They grow on sandy coastal soils and dunes. In the USSR, the European beach grass (A. arenaria) grows on the coasts and islands of the Baltic Sea. The plant is sometimes used to stabilize sandy coastal soils and dunes.

Bergson, quoting Fabre, has made play with the supposed extraordinary accuracy of the solitary wasp Ammophila, which lays its eggs in a caterpillar.
According to Fabre's observations, which Bergson accepts, the Ammophila stings its prey EXACTLY and UNERRINGLY in EACH of the nervous centres.
It can concluded that the high protein, moderate fiber contents and high in vitro digestibility found in Ammophila arenaria, Trigonella maritime and Vicia monantha, Vicia sativa, Ononis vaginalis, Atriplex nummularia and Lycium shawii make them good quality wild forage plant species that can be used in ruminants' nutrition under Egyptian rangelands conditions.
On coastal dunes, Ammophila breviligulata is often planted as a management technique to slow dune advance.
Because restoration of degraded dune systems is occurring and likely to continue, we examined the occurrence of amphibians in drainages associated with a coastal dune ecosystem degraded by invasive plants (European Beachgrass, Ammophila arenaria, and Iceplant, Carpobrotus edulis).

In fact Emery and Rudgers (2012) reported that Ammophila breviligulata, a native dominant dune-building grass of the Great Lakes inhibited growth of Centaurea in a greenhouse environment while its own growth was unaffected by the invader.

Also, Rau (1938) observed sleeping aggregations of the wasp Prionyx atratus (as Priononyx atratum) (Sphecidae) on weeds at the edge of a harvested wheat field and the wasp Ammophila nigricans (Sphecidae) roosting on low plants between a garden and 'the woods', in Missouri, USA.
Like Ammophila arenaria caryopses grown in the laboratory [2], the caryopses of these species have an optimal germination in the temperature range 15-25[degrees]C.
