Abstract This study details the floristic diversity of Mentheae (Lamiaceae - Nepetoideae) from Itatiaia National Park, first Protected Area in Brazil. Among 30 species Lamiaceae cited for we recorded 15 belonging to arranged seven genera: Cunila (2 spp.), Hedeoma (1 sp.), Hesperozygis Lepechinia Prunella Rhabdocaulon and Salvia (8 spp.). The region presents significant diversity, considering 62...

Due to its advantages, the use of clean energy in general and especially solar PV systems offer a great solution problems that people face their everyday life. Generation using system technology is cheaper compared one fossil fuels. Aside from this still has some drawbacks affect performance where ones caused by shadows are considered as big problems. This research work showed laboratory experi...

Phytochrome is thought to control the induction of leaf senescence directly, however, the signalling and molecular mechanisms remain unclear. In the present study, an ecophysiological approach was used to establish a functional connection between phytochrome signalling and the physiological processes underlying the induction of leaf senescence in response to shade. With shade it is important to...

The biometric factors of the host, soil properties, microclimate, and biologic components are influencing growth climber Piper species. However, ecological data is rarely available in scientific journals. This research aims to determine relationship between host plant P. decumanum University Papua Manokwari education forest. were acquired using systematic line method, with hypothetical plot sam...

Water availability is the most important limiting factor in arid lands. Any additional source of water, such as dew and fog, may have a positive impact upon the ecosystem. Dew and fog precipitation are largely dictated by weather conditions and habitat. Dew and fog measurements were carried out for 29 days in the fall of 1987–1989 at three distinctive habitats within a single drainage basin in ...

Dramatic shifts in community composition occur between vertical and horizontal rocky surfaces in subtidal environments worldwide, yet the forces mediating this transition are poorly understood. Vertical rock walls are often covered by lush, diverse communities of sessile suspension-feeding invertebrates, while adjacent horizontal substrates are dominated by algae, or corals in the tropics. Mult...
