Species–area relationships in continuous vegetation : evidence from Palaearctic grasslands [PDF]

open access: yes, 2019
Aim: Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas power laws best represent SARs.

Hybrid Osprey‐Salp Swarm Optimization Algorithm for Single and Multiobjective Optimal Power Flow in Smart Grids With Renewable Energy Integration

open access: yesEnergy Science &Engineering, EarlyView.
The proposed hybrid osprey‐salp swarm optimization algorithm addresses optimal power flow (OPF) problems in smart grids incorporating solar, hydro, and thermal generators. The algorithm is validated on Institute of Electrical and Electronics Engineers 30‐, 57‐, and 118‐bus test systems across five single and multiobjective OPF scenarios.

Community dynamics of insular biotas in space and time [PDF]

open access: yes, 2004
The various features determining species distributions remain enigmatic in ecology. This thesis deals with the spatial and temporal dynamics of land birds on the islands of the Dahlak archipelago, the Red Sea, and of mammals, birds and reptiles among the

Niche shifts after long-distance dispersal events in bipolar sedges (Carex, Cyperaceae) [PDF]

open access: yes, 2017
PREMISE OF THE STUDY: Bipolar species represent the greatest biogeographical disjunction on Earth, raising many questions about the colonization and adaptive processes behind such striking distribution.

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Significance of vertical transmission of arboviruses in mosquito-borne disease epidemiology

open access: yesParasites & Vectors
Mosquito-borne diseases (MBDs) are increasingly prevalent as a result of global change, with significant health and economic impacts worldwide. Dengue virus (DENV), chikungunya virus (CHIKV), Zika virus (ZIKV), yellow fever virus (YFV), Japanese ...

How the landscape of publishing is changing biogeography

open access: yesFrontiers of Biogeography, 2017
Open access, shifting publishing mores, predatory journals, reviewer over-burden are just a few of the factors reshaping modern scientific publishing. How are changes in the publishing environment influencing biogeography?

Winegrowers' Perceptions and Adoption of Sustainable Soil Management Practices and Technologies: A Case Study in Piedmont, Italy

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil is crucial for human survival but is threatened by erosion and contamination. Farmers play a pivotal role in soil conservation, thus, understanding what influences their decisions is crucial. The IN‐GEST SOIL project aimed to mitigate soil erosion and improve soil and vine quality in Piedmont vineyards, NW Italy.

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

open access: yesNordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Deriving risk maps from epidemiological models of vector borne diseases: State-of-the-art and suggestions for best practice

open access: yesEpidemics, 2020
Epidemiological models (EMs) are widely used to predict the temporal outbreak risk of vector-borne diseases (VBDs). EMs typically use the basic reproduction number (R0), a threshold quantity, to indicate risk.
