    Social Wasp-Flower Visiting Guild Interactions in Less Structurally Complex Habitats are More Susceptible to Local Extinction by Mateus Aparecido Clemente, Denise Lange, Wesley Dáttilo, Kleber Del-Claro, Fábio Prezoto

    Published 2013-11-01
    “…The simulations of cumulative removal of species showed that the network in the Riparian Forest is more robust against the removal of both plants and wasps than that network in Rocky Grassland, since their extinction curves declined more slowly. …”

    Study and Prediction of Land Use/Cover Change in Small and Medium-Sized River Basins in Typical Urbanization Areas by LI Liujie, LIU Bingjun, WEI Qiuying

    Published 2022-01-01
    “…In order to explore the spatio-temporal evolution pattern of land use in small and medium-sized river basins under the background of rapid urbanization,this paper studied the Baiyun Lake basin and analyzed the structure change in land use in the Baiyun Lake basin from 1980 to 2020 by using land use dynamic degree and land use intensity.In addition,the paper employed a standard deviation ellipse model to analyze the spatial pattern change in the basin,discussed the influence on the land use in the basin before and after the completion of Baiyun Lake,and utilized a CA-Markov model to simulate the land use in the basin in the 2030 and explore the pattern evolution trend of land use in the basin in the future.The results show that:① The land in the Baiyun Lake basin from 1980 to 2020 was mostly used for construction,with an average annual proportion of 51.77%,and in 2020,the proportion reached 70.13%.② In the past 40 years,the land use in the basin has changed from cultivated land,dry land,forest,and grassland to construction land.The land use intensity has continued to rise,and the land structure has gradually tended to be single.③ Baiyun Lake occupies part of the urban land,so the land use in the basin will focus on the adjustment of forest and construction land in 2030.The land use intensity will change slowly,and the urban construction space will be controlled to a certain extent.…”

    Predicting vector distribution in Europe: at what sample size are species distribution models reliable? by Lianne Mitchel, Lianne Mitchel, Guy Hendrickx, Ewan T. MacLeod, Cedric Marsboom, Cedric Marsboom

    Published 2025-05-01
    “…Comparatively, unbalanced samples with a 20:80 ratio of presence and absence data did not produce reliable models with any of the sample sizes considered.ConclusionTo our knowledge, this is the first study to use a simulated vector to identify the optimum sample size for Random Forest models at this resolution (≤1 km2) and extent (≥10,000 km2). …”

    Fire Protection of Utility Pine Wood Poles by José Saporiti Machado, Elisabete Cordeiro, Sofia Knapic, Telmo Morgado, Alfredo M. P. G. Dias

    Published 2024-12-01
    “…In the present study, different fire protection measures were applied to utility wood poles aiming to protect them from wildfires, ensuring their reuse in safe conditions while preventing them from contributing to the propagation of forest fires, particularly surface fires. Two of the solutions tested were based on intumescent paints, while the other one involved a system that completely covers the poles’ exteriors (a fabric-protection layer mechanically applied to the surface of the pole). …”

    Correlated‐replicate occupancy models for wild turkey gobbling call‐count surveys by Christopher D. Pollentier, Michael A. Hardy, R. Scott Lutz, Scott D. Hull

    Published 2019-09-01
    “…Turkeys occurred throughout a variety of habitat conditions, but occupancy was greatest (ψˆ = 0.990 ± 0.03) along survey routes with 40–60% forest cover. We fit simulated data to standard occupancy models and correlated replicate models and found occupancy and detection estimates were underestimated by as much as 10% with standard occupancy models, but bias was negligible under the correlated replicate modeling approach. …”
