İklim değişimi ve buna bağlı faktörlerden en çok etkilenen ormanlardır. değişikliği, konukçu ağaçların bunlarla ilişkili olan zararlıların dağılımlarında değişikliğe neden olmaktadır. Ekoloji koruma alanındaki planlamacılara yol gösterecek uygulamalar için türlerin coğrafi dağılımlarını belirleyen tahmine dayalı modeller önemlidir. Orman ekosistemlerinde ciddi olumsuzluklara kabuk böceklerinin her yıl artarak devam eden zararlarının önemli sonuçlar meydana getireceği beklenmektedir. Bu nedenle orman bulunan böceği türlerinin potansiyel dağılımlarının belirlenmesi sürdürülebilir yönetimi açısından oldukça salgınlarını iklim, topoğrafik meşcere parametreleri ölçüde etkilemektedir. çalışmada, Maksimum Entropi (MaxEnt) yaklaşımı kullanılarak 19 farklı biyoiklimsel değişken ile kapalılık, yükselti eğim değişkenlerini dikkate alarak Ips sexdentatus’un zararına ilişkin duyarlılık haritası oluşturulmuştur. Modelin doğruluğu alıcı çalışma karakteristiği (ROC) analizi değerlendirilmiş eğitim verilerinde eğri altında kalan alan (Area Under Curve, (AUC)) 0,846; test ise 0,855 olarak hesaplanmıştır. haritasında model sonucunu etkileyen parametrenin kapalılık olduğu modelin %68.5’ini oluşturduğu belirlenmiştir. Bunun yanında nemli ayın yağış miktarı değişkenlerinin toplu %88.4’ünü görülmüştür. Ayrıca, alanının % 51.6’sı sexdentatus istilası riskli kategoride yer almaktadır. çalışmanın sonuçları izlenmesi mücadele stratejilerinin belirlenmesine katkı sağlayacaktır. Aynı zamanda diğer salgın yapma potansiyeline sahip bir öngörü oluşturacaktır.

Introduction Forest assisted migration has been proposed as a means to align tree populations with shifting climate habitats under change. Here we report on the growth and survival of oak species seed sources at five trials in southern Ontario – an important transition zone between boreal temperate ecosystems. Methods Each trial featured one or more including red ( Quercus rubra ), white Q. alba burr macrocarpa swamp bicolor ) from Ontario, Pennsylvania, and/or Tennessee. The were measured for height 7 13 years after planting. Results For several species, performed nearly well local sources. However, significantly worse than 2 eastern Ontario. These outcomes may have influenced by reduced quality source planting stock these trials. Discussion Our findings generally support previous work that suggests northward movements hundred kilometers be safe efforts involving broadleaf species. Notably, sites located northern range limits two this study suggesting potential modest expansions boreal-temperate zone. help forest managers better understand

Abstract Agricultural intensification has led to landscape homogenisation across major parts of Europe and reduced diversity in flora fauna. In Central Europe, the species composition insect groups is increasingly dominated by a few ecologically generalist mobile species. So far, however, degree stability population sizes today's anthropogenic landscapes comparison pre‐Anthropocene hardly been analysed. Here, we studied large museum records Lepidoptera from northern Austria spanning years 1990–2022 infer trends sizes. On average, dynamics decreased increased significantly over time. This trend was most pronounced lowland regions, where agricultural transformed former heterogeneous into intensively managed grasslands fields. Community structures are now ubiquitous Habitat specialist existing isolated patches particularly A metapopulation structure appeared have stabilising effect on dynamics. We conclude that altered community might not only stem selective decline but also patterns stochasticity. Higher associated with faunal homogenisation. Precise butterfly sensitivity analyses require long‐term data average composition.

Abstract Understanding how species distributions and associated habitat are impacted by natural anthropogenic disturbance is central for the conservation of rare forest carnivores dependent on subalpine forests. Canada lynx at their range periphery occupy forests that structured large-scale fire insect outbreaks increase with climate change. In addition, Southern Rocky Mountains western United States a destination winter recreationists worldwide an high degree urbanization resort development. We modeled reintroduced population in using ensemble distribution model built abiotic biotic covariates validated independent locations including satellite telemetry, aerial camera traps, den locations, backtracking. Based this model, we delineated Likely Core lynx-habitat as thresholds captured 95% 50% testing data, respectively. (5727 km 2 ) (441 were spatially limited patchily distributed across Colorado, USA.

Although overlap was low (5%), future burns likely represent greatest potential impact over decades-long timeframes. The publicly owned lands administratively classified “protected” (62% overlap) (49%) may insulate from permanent conversion due to direct human (urbanization, development).
