Since the 1980s, populations of Acropora cervicornis and A. palmata have experienced severe declines due to disease anthropogenic stressors; resulting in their listing as threatened, need for restoration. In this study, larval survival competency data were collected used calibrate a very high-resolution hydrodynamic model (up 100m) determine dispersal patterns species along Florida’s Coral Reef...

Ecological environmental security in karst areas is an issue of global concern. Identifying the ecological landscape pattern (ELSP) key to promoting protection and alleviating land development utilization impacts. sources (ESs) corridors (ECs) are important bases for constructing ELSP. We used five influencing factors (land use type, digital elevation model (DEM), rocky desertification degree, ...

Across the US Coastal Plain, native grasses and legumes may provide viable alternatives to monoculture pastures of introduced sod‐forming grasses, which require recurring costly inputs. Some available cultivars mostly from neighboring regions, have potential combine forage production for grazing livestock with enhanced habitat, especially grassland birds. A few legume species enhance ecosystem ...

In theoretical chemistry, -modified Wiener index is a graph invariant topological index to analyze the chemical properties of molecular structure. In this note, we determine the minimum -modified Wiener index of graph with fixed connectivity or edge-connectivity. Our results also present the sufficient and necessary condition for reaching the lower bound.

the stability of a communication network composed of processing nodes and communication links is of prime importance to network designers. as the network begins losing links or nodes, eventually there is a loss in its effectiveness. thus, communication networks must be constructed to be as stable as possible, not only with respect to the initial disruption, but also with respect to the possible...

Abstract Quantitative identification of the covariation between sediment connectivity and soil erosion can contribute to provide key information for watershed management. However, this its spatiotemporal response mechanisms are still unclear, especially whether be used as a basis identifying critical source areas in large‐scale ecological restored watersheds. In study, an integrated methodology...

the first extended zeroth-order connectivity index of a graph   g is defined as 0 1/2 1 ( ) ( ) ,   v   v v g      g d      where   v   (g) is the vertex set of g, and v d is the sum of degrees of neighbors of vertex v in g. we give a sharp lower bound for the first extended zeroth-order connectivity index of trees with given numbers of vertices and pendant vertices,...

conclusions the most common cause of restoration replacement in patients referred to the babol university of dentistry during years 2013 and 2014 was secondary caries that were found in class ii restorations. patients and methods age, sex, type of occlusion, dmf, existing parafunction, type of tooth, class and reason of composite restoration replacement was recorded for patients who had referre...
