In Southern California, the red willow (Salix laevigata Bebb) hosts a variety of gall-inducing parasitic insects. However, little is known about the ecology of these parasites, particularly the characterization of their microclimate preferences. This study explores the relationship between microclimate and gall frequencies in S. laevigata in the Ballona Wetlands and Temescal Canyon, and gall count correlated with biotic... Read more.

Hagenia-shaped habitat is an important element in conservation of world’s only population of mountain gorillas surviving in the wild. In fact, in the Parc National des Volcans (henceforth PNV), gorillas spend most of their life time in the nutritious herbaceous habitats near or within the Hagenia-Hypericum zone. Unfortunately, populations of Hagenia abyssinica in this park have been reported to be ageing. Using... Read more.

Vepris heterophylla (Engl.) Letouzey (Rutaceae) is a useful and threatened plant of Sudano-Sahelian zone of Cameroon. However, its description is not clear. This study aims to evaluate morphological variations among ten populations to delimitating the V. heterophylla morphotypes in the zone. Two hundred and fifty (250) individuals belonging to 10 populations were assessed by morphological descriptors including eight... Read more.

Macroinvertebrates formed an important constituent of an aquatic ecosystem and had functional importance in assessing the trophic status as the abundance of benthic fauna mainly depends on physical and chemical properties of the substratum and thus the benthic communities respond to changes in the quality of water and available habitat. This review discussed the occurrence, compo-sition and distribution of... Read more.

Arbuscular mycorrhizal fungi (AMF) play a key role in land reclamation, sustaining soil fertility and cycling of nutrients, which in turn increases plant vigour and productivity. AMF differ in both structural characteristics and global distribution, which is strongly correlated with the respective functional role. This study investigated the molecular diversity of arbuscular mycorrhizal fungi (AMF) in selected... Read more.
