Coastlines globally are sensitive to the effects of sea-level rise, increased coastal storminess and changes in sediment supply dynamics Anthropocene. also influenced by land use change, urbanization development built infrastructure. These can affect landforms, weaken resilience make coasts more climate hazards. This study critically examines properties coastlines that contribute biophysical South Africa, highlighting their relativerates change dynamic behaviour response physical human forcing factors. Coastal landforms be considered as 'green infrastructure' buffer well providing ecosystem environmental services own right. Viewing green infrastructure provides a 'nature-based solution' mitigate against impacts work with – not natural geomorphic, sedimentary ecological processes coastlines. socioecological resilience, where they provide services. The approach has been developed Africa but is effective supporting sustainable development.

Climatic Influence on Growth Performance of Abies spectabilis in the Himalayas

Forests, Год журнала: 2025, Номер 16(3), С. 473 - 473

Опубликована: Март 8, 2025

Climate change has affected forest ecosystems across the world over past century. However, its impact is particularly high in Himalayas due to increasing temperatures, extreme precipitation events, and regional droughts. In this context, a review of current stage research was deemed necessary understand adaptation key conifer species climate variability Central Himalayas. Hence, we conducted systematic published peer-reviewed journal articles addressing growth performance Abies spectabilis (D. Don) Spach From review, three main patterns response have emerged: positive correlation radial tree with temperature previous growing seasons, limitation by winter temperature, or moisture pre-monsoon season. Overall, results indicate an elevation-dependent sensitivity, crucial role availability, seasonal shifts climate–growth relationships, reflecting species’ adaptability changing conditions. Our revealed that studies on wood anatomical traits A. are still rare. The tree-ring shows complex variability, as well decreasing trends distribution range.

A new gecko (Phyllodactylidae: Homonota whitii group) from the Diaguita highlands, Argentina, with an updated phylogeny for the genus

Abstract The South American Transition Zone (SATZ) connects the Neotropical and Andean regions, stretching from western Venezuela to northern Chile central‐western Argentina. In Argentina, northwestern Altoandina Cuyana province includes arid semi‐arid ecosystems, particularly Diaguita District, spanning Catamarca, La Rioja San Juan. This mountainous region, including Sierra de Famatina Cordillera Frontal los Andes, hosts species adapted extreme conditions. Despite its biodiversity, region's endemicity phylogenetic uniqueness remain poorly understood, especially as these ecosystems face growing climate threats, such heatwaves. Geckos (Order Gekkota) are one of oldest lizard clades, with divergences over 150 million years ago. Particularly, genus Homonota (Phyllodactylidae) is endemic southern cone America, primarily in also found Brazil, Paraguay, Bolivia Uruguay. As part a broader investigation on geckos this advance their systematic study, we generated data two mitochondrial 12 autosomal loci across 14 species, along comprehensive morphological dataset meristic measurements scale counts. Detailed analyses were conducted within an integrative assessment framework. Consequently, describe new biogeographic district representing northernmost member H. whitii group. inhabits region known for micro‐endemism, further highlighting area important biodiversity hotspot dryland ecosystems. Additionally, provide updated molecular hypothesis genus, offering insights into evolutionary history SATZ.

Abstract Global climate change gives rise to changing spatial patterns of snow and ice, especially over mountain blocks where orographic synoptic circulation effects play significant roles in creating precipitation glacier development. The presence ice results heat balance changes other land surface feedbacks that have implications for retreat the dynamics geomorphic systems. This study considers sensitivity cryosphere (snow, permafrost) global change, this analysis evaluating stability, generation geohazards. Consideration these issues is informed by evidence from case studies reported literature field observations system worldwide. Results show ‘sensitivity’ forcing has been interpreted defined different ways snow, permafrost systems, with respect properties such as albedo, mass or rapidity change. There are also differences between permafrost, regions therefore likely follow trajectories response forcing, related their physiographic extent cryospheric coverage. Within glaciated mountains particular, relative timing events, interplay slope, front, proglacial sediment sources environments, may vary depending on size, setting, microclimate. By contrast, responses warming (increased instability movements) (avalanche risk, floods) quite temporal influenced environmental controls.

An Integrated Grassland Fire-Danger-Assessment System for a Mountainous National Park Using Geospatial Modelling Techniques

Fire, Год журнала: 2024, Номер 7(2), С. 61 - 61

Grasslands are key to the Earth’s system and provide crucial ecosystem services. The degradation of grassland in South Africa is increasing alarmingly, fire regarded as one major culprits. Globally, anthropogenic climate changes have altered regimes biome. Integrated fire-risk assessment systems an integral approach prevention mitigate negative impacts fire. However, risk-assessment extremely challenging, owing myriad factors that influence ignition behaviour. Most danger do not consider causes; therefore, they inadequate validating estimation danger. Thus, models should comprise potential causes Understanding drivers occurrence sustainable management Africa’s ecosystems. Therefore, this study explored six statistical machine learning models—the frequency ratio (FR), weight evidence (WoE), logistic regression (LR), decision tree (DT), random forest (RF), support vector (SVM) Google Earth Engine (GEE) assess Afromontane protected area (PA). under receiver operating characteristic curve results (ROC/AUC) revealed DT showed highest precision on model fit success rate, while WoE was used record prediction rate (AUC = 0.74). 53% susceptible land surface temperature (LST) vegetation condition index (VCI) were most influential factors. Corresponding analysis suggested regime fuel-dominated. strategies within Golden Gate Highlands National Park (GGHNP) include fuel aiming at correctly weighing effects spread.
