Do Static Externalities Offset Dynamic Externalities? An Experimental Study of the Exploitation of Substitutable Common-...
Overexploitation of coastal aquifers may lead to seawater intrusion which irreversibly degrades groundwater. The seawater intrusion process may imply that its' consequences would not be perceptible before decades of accumulated overexploitation. In such a dynamic setting static externalities may enhance the users' awareness about the resource's com...
Light-mediated influence of three understorey species (Calluna vulgaris, Pteridium aquilinum, Molinia caerulea) on growt...
Pinus sylvestris is a pioneer species and as such is relatively light-demanding. Therefore, its natural regeneration may be inhibited by some forest understorey species that develop with light and can then reduce light as well as soil resources (i.e. nutrients and water) availability for the pine seedlings. To better quantify these effects, we desi...
Foundations of the cover crop technique and potential use in afforestation
In many circumstances in afforestation, the quick development of very competitive herbaceous and shrubby species can compromise tree establishment. At present, this vegetation is often controlled by chemical and mechanical operations, whereas they are criticized from environmental points of view; some alternatives are under study. The cover crop te...
Asymptotic properties of infinite Leslie matrices
The stable population theory is classically applicable to populations in which there is a maximum age after which individuals die. Demetrius [1972. On an infinite population matrix. Math. Biosci. 13, 133137] extended this theory to infinite Leslie matrices, in which the longevity of individuals is potentially infinite. However, Demetrius had to ass...
