Males of Euphydryas editha (Lepidoptera: Nymphalidae) need their antennae to mate successfully, but females do not. Antennal structure was investigated in the hope of explaining this functional dimorphism, which is opposite to that in other butterfli

As the alien species that most dominates space along the South African coast, the Mediterranean mussel Mytilus galloprovincialis has radically altered community composition on invaded shores. We experimentally assessed interspecific interactions betw

The Mediterranean mussel Mytilus galloprovincialis is the most widespread marine alien species along the South African coast. Long-term monitoring of the mid-to-low intertidal zone in the Groen-Spoeg area on the west coast between 1988 and 1993 track

Populations of a protandric limpet, Cymbula oculus , were compared between two South African Marine Protected Areas (MPAs), Dwesa and Tsitsikamma, and four exploited sites, and between sites exposed to or sheltered from strong wave action. Harvesting

Spatial aggregations of organisms are common in nature. Aggregations have often been thought to play important roles in mate-finding, predator avoidance, reduction of water loss, or the acquisition of food and other resources, yet few empirical studi

Multifunnel traps baited with frontalin and turpentine have been used to investigate dispersal of southern pine beetles, Dendroctonus frontalis Zimmermann, and are routinely used in the southern United States to monitor population trends of this seri

An individual's success at locating resource items is largely determined by the manner in which it searches. Studies on the movement trajectories of individuals have therefore been useful in elucidating mechanisms by which animals find their resource

Three objective criteria for assessing sites being considered as marine nature reserves are developed and applied to a region of the west coast of South Africa, between the Groen and the Spoeg rivers, that has been mooted as a possible nature reserve

We describe a method of quantifying insect paths in the field for use in ecological and behavioral studies. First, we discuss how continuous and curvilinear paths traced by moving insects can be approximated with a series of connected straight lines.

Numerous studies have documented the influence of environmental factors such as host plant species and host quality on the oviposition behavior of female insects. This paper shows that an internal physiological factor, the number of mature eggs a fem
