In addition, seeds are vulnerable to rat and invertebrate predation. Seventy-two seeds were collected from one prolifically fruiting tree in Makaha this year and taken ...

long term study of competition between two co

Long-term data on co-existing A. astacus and P. leniusculus demonstrate that they cannot live in sympatry without competition in which P. leniusculus with its larger body and chela size, faster growth, more aggressive behaviour and greater fecundity would be the stronger. However, a similar weakenin ...

avoidance and tolerance to avian herbivores in aquatic plants

The presence of aquatic vegetation may greatly ameliorate water quality, but some species do so more than others (c.f. van den Berg et al., 1999). It i ...
