Community and ecosystem changes in tallgrass prairie restorations: the effects of population source and diversity
… quantify the effects of dominant grass propagule source (i.e., cultivar vs. non-cultivar) and seeded diversity of propagules on community structure and ecosystem function during prairie restoration. Two field experiments, and two chronosequences were used to investigate this main objective. The …

When do propagules matter? The role of ecological filters and regeneration dynamics during community assembly in tallgrass prairie restorations
… consisting of a split plot design with population source of dominant grasses (cultivar vs. local ecotype) and sown subordinate species (three unique pools of non-dominant species) as the subplot factor, respectively. Different sown species pools were included to assess whether any …

Leopard population dynamics, trophy hunting and conservation in the Soutpansberg Mountains, South Africa
… interviews in order to investigate leopard population density and dynamics, human-leopard conflict and the potential and effectiveness of trophy hunting as a conservation tool for leopards in the Soutpansberg Mountains, Limpopo Province, South Africa. Results from camera trapping data show …

Effect of Population Sources and Species Pools on Community Phylogenetic and Functional Diversity During Restoration
… the effect of intraspecific genetic variation (population sources) and species pools on evolutionary relatedness of coexisting species and ecosystem functioning (such as productivity). The first study examined the importance of incorporating phylogenetic approach into restoration ecology to …

Where is the love? Experimental translocation of the threatened striped legless lizard (Delma impar) and an investigation of the habitat suitability of the invasive African lovegrass (Eragrostis curvula)
… dispersal limited species occurring in isolated populations. Where populations of threatened species are certain to be lost due to habitat destruction, salvage and translocation of individuals to suitable unoccupied habitat may mitigate some of the loss if translocation is thoroughly planned and …

Combining ecological niche models and dispersal simulations to predict bryophytes dynamic response to climate changes
… de colonisation isotrope autour d’une population source avec un noyau (kernel) de dispersion constant dans l’espace. Ceci rendait problématique son utilisation dans le cas d’organismes dispersés par le vent car (i) les courants aériens sont directionnels et (ii) la vitesse du vent varie …
