Distribution and Conservation of Ephedra rhytidosperma

open access: yesEcology and Evolution
With global warming and increasingly intensified human activities, numerous species are on the verge of extinction, ca. 28% of living species are threatened globally, although conservation of endangered species has received worldwide attention.

Enhancing Conservation Efforts in the Qinling Mountains Through Phenotypic Trait Diversity Optimization

open access: yesPlants
The establishment of conservation areas is considered one of the most effective approaches to address biodiversity loss with limited resources. Identifying hotspots of plant diversity and conservation gaps has played a crucial role in optimizing ...

Identifikasi Kinerja dan Kesenjangan Stakeholder dalam Pelestarian Elang Jawa [Spizaetus Bartelsi] [PDF]

open access: yes, 2010
This approach is quite different from existing conservation actions, which are site based and fragmented. Research was conducted since December 2009 until February 2010 in Gunung Gede Pangrango National Park (GGPNP), Telaga Warna Nature Reserve and its ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Use of canopy gap openings to restore coniferous stands in Mediterranean environment

open access: yesiForest - Biogeosciences and Forestry, 2017
In Mediterranean regions, climate change increasingly affect tree species distributions. Conifer forests under continuing disturbance show a more rapid shift to dominance by beech and other temperate broadleaves. Thus, there is an urgent need to conserve

Hotspots and conservation gaps: A case study of key higher plant species from Northwest Yunnan, China

open access: yesGlobal Ecology and Conservation, 2020
Northwest Yunnan is rich in flora and is home to many key higher plant species with endemic and endangered attributes. However, there are still some species and biodiversity hotspots that are not included in the established reserve system.

Soft Magnetorotons and Broken-Symmetry States in Bilayer Quantum Hall Ferromagnets [PDF]

open access: yes, 2003
The recent report on the observation of soft magnetorotons in the dispersion of charge-density excitations across the tunneling gap in coupled bilayers at total Landau level filling factor $\nu_T=1$ is reviewed. The inelastic light scattering experiments

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Dirac Fermions in Inhomogeneous Magnetic Field

open access: yes, 2010
We study a confined system of Dirac fermions in the presence of inhomogeneous magnetic field. Splitting the system into different regions, we determine their corresponding energy spectrum solutions.
