Oriental arborvitae (Platycladus orientalis) is an important afforestation and ornamental tree species, which is native in eastern Asian. Therefore, a global suitable habitat map for oriental arborvitae is urgently needed for global promotion and cultivation. Here, the potential habitat and climatic requirements of oriental arborvitae at global scale were simulated using herbariums data and 13 ...

Despite a long history of the study of tropical forests, uncertainty about the importance of different ecological processes in shaping tropical tree species distributions persists. Traitand phylogenetic-based tests of community assembly provide a powerful way to detect community assembly processes but have seldom been applied to the same community. Both methods are well suited to testing how th...

Taxa co-occurring in communities often represent a nonrandom sample, in phenotypic or phylogenetic terms, of the regional species pool. While heuristic arguments have identified processes that create community phylogenetic patterns, further progress hinges on a more comprehensive understanding of the interactions between underlying ecological and evolutionary processes. We created a simulation ...

1 2 Understanding the habitat requirements of a species for breeding is essential for its 3 conservation, particularly if the availability of suitable habitat is a limiting factor for 4 population growth. This is postulated to be the case for grey seals, one of the more 5 abundant marine apex predators in northern European waters. In common with similar 6 studies that have investigated the habi...

Metapopulations are a central concept in ecology and conservation biology; however, estimating key parameters such as colonization rates presents a substantial obstacle to modelling metapopulations in many species. We develop spatial and non-spatial simulation models that combine incidence- and demographic-based approaches to build a relationship between observed patch occupancy, habitat turnov...

this research was conducted to study the length-weight and length-length relationships and condition factor of six cyprinid fish species viz. alburnus atropatena , barbus lacerta , capoeta capoeta , carrasius gibelio , romanogobio macropterus and pseudorasbora parva from zarrineh river (urmia lake basin, iran). a total of 188 specimens ranging from 2.9 to 21.4cm in total length and 0.22 to 176g...

This paper is devoted to the study of a reaction-diffusion Lyme disease model with seasonality. In the case of a bounded habitat, we obtain a threshold result on the global stability of either disease-free or endemic periodic solution. In the case of an unbounded habitat, we establish the existence of the disease spreading speed and its coincidence with the minimal wave speed for time-periodic ...

This paper discusses a proposed processing technique for combining video imagery with auxiliary sensor information. The latter greatly simplifies image processing by reducing complexity of the transformation model. The mosaics produced by this technique are adequate for many applications, in particular habitat mapping. The algorithm is demonstrated through simulations and hardware configuration...

Understanding the time evolution of fragmented animal populations and their habitats, connected by migration, is a problem of both theoretical and practical interest. This paper presents a method for calculating the time evolution of the habitats’ population size distribution from a general stochastic dynamic within each habitat, using a deterministic approximation which becomes exact for an in...
