Acute bovine liver disease (ABLD) is a hepatotoxicity principally of cattle which occurs in southern regions of Australia. Severely affected animals undergo rapid clinical progression with mortalities often occurring prior to the recognition of clinical signs. Less severely affected animals develop photosensitization and a proportion can develop liver failure. The characteristic histopathologic...

Hedgehog dogtail (Cynosurus echinatus) is an annual grass, native to Europe, but also widely distributed in North and South America, South Africa, and Australia. Two hedgehog dogtail biotypes, one diclofop-methyl (DM)-resistant and one DM-susceptible were studied in detail for experimental dose-response resistance mechanisms. Herbicide rates that inhibited shoot growth by 50% (GR50) were determ...

Seed germination generally presents a peak in the next growing season after a fire. Among other factors associated with fire are the increase of soil nitrogen and changes in the pH of the soil. In this study, we addressed the question, whether or not the germination response of eight species is linked with the increase in pH and nitrogenous compounds in the germination media? We assessed the se...

(1) Ramets of Trifolium repens were sampled from sites in a field of permanent pasture dominated by a mosaic of Lolium perenne, Holcus lanatus, Cynosurus cristatus and Agrostis tenuis. After multiplication of the ramets in a glasshouse, they were transplanted back into the original swards in all combinations of clover 'type' and site of origin. The pre-existing vegetation on the sites was eithe...

The main purpose of the 92/43/EEC Habitats Directive is to contribute conservation biodiversity, understood as habitat types and species flora fauna European Union. To achieve this goal, natural semi-natural biodiversity a whole must be recognized included in its annexes. As for biotopes, named types, Italy unfortunately lacking it Annex I does not include important ecosystems that are typical ...

Biodiversity is currently undergoing a human-induced extinction crisis comparable to previous mass extinctions (Ceballos et al., 2015; Dirzo 2014; Pievani, 2014). Among the main drivers of loss, climate change has already impacted biodiversity from individual genotypes whole ecosystems (IPBES, 2019; Scheffers 2016). This resulted in species extinctions, local extirpations and changes distributi...
