The relationship between grain size and changes in dune morphology is characterized by analyzing sediment samples from various parts of dunes. The results indicate that, on the primary ridge, mean grain size becomes finer from the toe of the stoss slope to the top of the dune crest, with further variations down the lee slope before coarsening again within inter-dune areas. Grain-size patterns differ for the secondary ridge, where grains are finer at the stoss slope and dune crest under north wind conditions, while the toe of the lee slope has coarser sediment. The coarse grain size on the primary ridge can be attributed to the underlying sediment, which is dominated by disorderly coarse particles with multiple peaks at sizes less than or equal to 2.5 Φ. Coarser grains on the lee slope of the secondary ridge result primarily from airflow deflection at the lee slope. The stoss slope of the secondary ridge erodes as oblique airflow interacts with the dune, deflecting the airflow along its lee slope to promote longitudinal sand transport in this area. This phenomenon also causes fluctuations in mean grain size along the north-south axis of the primary ridge. The observed grain-size distribution response to changes in dune morphology appears largely influenced by the presence of a “short secondary ridge” under north wind conditions. These ridges create a narrow gap, accelerating the west wind and contributing to the coarse grain sizes on the lee slopes. This research may enhance understanding of reticulate dune development mechanisms in dual wind environments, shedding light on the dynamic sedimentary processes of these complex structures.</div></div>","PeriodicalId":51080,"journal":{"name":"Journal of Arid Environments","volume":"226 ","pages":"Article 105279"},"PeriodicalIF":2.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142757649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The family Cactaceae, found predominantly in xeric habitats, is particularly vulnerable to the effects of climate change. To assess the potential impacts of climate change, ecological niche models (ENMs) have become essential tools in ecology, biogeography, and conservation. Here, we used ENMs algorithms, such as MaxEnt, Generalized Linear Models (GLM), and Artificial Neural Networks (ANN), to forecast the future distribution of <em>Cereus</em> species (Cactaceae), focusing on their response to climate change. Our analysis targeted five species, utilizing shared socioeconomic pathways (SSPs) to project their distribution from 2030 to 2090, comparing these with models for the last glacial maximum (∼21 ka). Our results suggest that <em>C. stenogonus</em> K.Schum. and <em>C. bicolor</em> Rizzini &amp; Mattos are prone to experience a decline in distribution range, independent of the SSP scenario. Overall, the results also indicate that the effects of anthropogenic climate change differ from those of natural Pleistocene aridification, refuting our previous expectations.

We then used spatial analysis to assess hot spots of cacti' habitat suitability and their overlap and mismatch. A total of 217 (55.2%) species had their habitat suitability primarily influenced by measures of precipitation (170 species), precipitation seasonality in particular, and temperature (77 species). Our study reveals climate change will impact cacti habitat suitability across North America's drylands. We also report a strong overlay among HVCA in current and future climate scenarios.

Human-induced global climate change underscores the importance of such refugia, which directly impacts species distribution, especially for ectothermic species relying on the environmental temperature to keep their metabolism active. <em>Tropidurus cocorobensis</em> is an endemic, heliothermic, and generalist lizard from Caatinga, a heterogeneous semi-arid domain characterized by low and irregular precipitation patterns and high temperature and solar radiation. Despite its endemism, there is no information concerning temporarily stable (refugial) and unstable (recently colonized) regions for its occurrence, nor future predictions of local thermal suitability in different climate change scenarios. Using ENMs, we assessed Caatinga's past, present, and future thermal suitability for <em>T. cocorobensis,</em> identifying potential changes in its thermal refugia over time. Our results indicated Depressão Sertaneja Meridional (DSM) and Campo Maior Complex (CMC) as climatically stable Caatinga Ecoregions, serving as climate refugia for <em>T. cocorobensis.</em> While DSM covers much of the species' current distribution, CMC lacks occurrence data. Contrastingly, the Chapada Diamantina Complex, a known habitat for the species, was not recovered as a climate refugia nor was suitable for future scenarios, therefore representing a climatically unstable area. Future projections indicate a potential expansion of <em>T. cocorobensis'</em> climate refugia, possibly linked to the species' generalist habits. However, the optimistic outlook for this species may not mirror the overall well-being of the Caatinga domain since generalist species often fill niches left by specialists unable to adapt to stressful environments. Future studies should prioritize comparing the climatic refugia of specialist and generalist species envisioning a comprehensive understanding of the ecological dynamics within the Caatinga ecosystem. This approach will be crucial for formulating effective conservation strategies amid the ongoing challenges of climate change in this domain.</div></div>","PeriodicalId":51080,"journal":{"name":"Journal of Arid Environments","volume":"226 ","pages":"Article 105281"},"PeriodicalIF":2.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142705216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
