Drosera sessilifolia, a tiny carnivorous plant whose adult size is around 3 cm, sometimes inhabits the humid zone know as the "campo limpo umido" in the Brazilian Cerrado region D. sessilifolia rarely occurs in the swampy area along the stream in this region: however, its occurrence is expected to decline with agricultural development. In the present study, we examined the factors determining the habitat and growth of D. sessilifolia in the campo limpo umido as well as how these factors have been modified by agricultural developments. Our survey suggests that the growth of D. sessilifolia is greatly influenced by light in areas where sufficient soil mmoisture is available. The light environment at the edge o a track constructed for reasons of agricultural development is in fact more suitable for D. sessilifolia than found in the areas formerly inhabited by it. However, soon after construction, the artificial habitat may be occupied by tall-growing plants. In the former habitat of D. sessilifolia, the amount of accumulated litter and the size of the submerged spot also influenced its growth. In order to conserve short-growing plants, like D. sessilifolia in the plant community, the accompanhying tall-growing dominant grasses should be controlled by periodic human disturbance. |

Rising emissions of anthropogenic greenhouse gases such as carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) are a key driver of climate change, which is predicted to have myriad detrimental consequences in coming years if not kept in check. Given the potency of CH4 in terms of trapping heat in the atmosphere in the short term, as well as the fact that ruminant production currently contributes approximately 30% of anthropogenic emissions, there is an impetus to substantially decrease the generation of ruminant-derived CH4. While various strategies are being assessed in this context, a multi-faceted approach is likely required to achieve significant reductions. Feed supplementation is one strategy that has shown promise in this field by attenuating methanogenesis in rumen archaea; however, this can be costly and sometimes impractical. In this review, we examine and discuss the prospect of directly modulating forages and/or rumen archaea themselves in a manner that would reduce methanogenesis using CRISPR/Cas-mediated gene editing platforms. Such an approach could provide a valuable alternative to supplementation and has the potential to contribute to the sustainability of agriculture, as well as the mitigation of climate change, in the future. |
