ITS1 metabarcoding revealing Phytophthora diversity in anthropized and natural ecosystems in Sicily, Italy

This dataset on Zenodo contains the raw sequencing data for: <a href="https://doi.org/10.3390/jof8040330">La Spada et al. (2022) DNA Metabarcoding and Isolation by Baiting Complement Each Other in Revealing Phytophthora Diversity in Anthropized and Natural Ecosystems</a>. This a subset of 192 demultiplexed Illumina MiSeq raw sequencing samples run at the James Hutton Institute in January 2020, consisting of two 96-well plates labelled with the Illumina A and D multiplexing kits. There are 61 pairs of raw gzipped compressed FASTQ files (122 files), provided as a 930MB gzipped compressed tar-ball. From the D multiplexing kit, there are 27 Nature Reserve (NR) samples, 16 Botanical Garden (BG) samples, and 6 managed Citrus Orchard (CO) samples containing Phytophthora targeted ITS1 marker sequences, and 6 synthetic controls (prefix GL1D) which should have contained only four known synthetic sequences. Additionally included are the 6 synthetic controls (prefix GL1A) from the A multiplexing kit, which were clean. The filenames start with the sample name, followed by something like DH03_S183_L001_R1_001.fastq.gz where DH03 indicates well H03 on the 96-well plate labelled with the D multiplexing set, S183 is the MiSeq sample number (from 1 to 192), and R1 (or R2) indicate the Illumina forward (or reverse) paired read files.

Data from: Worldwide impacts of landscape anthropization on mosquito abundance and diversity: a meta-analysis

In recent decades, the emergence and resurgence of vector-borne diseases have been well documented worldwide, especially in tropical regions where protection and defence tools for human populations are still very limited. In this context, the dynamics of pathogens are influenced by landscape anthropization (i.e., urbanization, deforestation, and agricultural development), and one of the mechanisms through which this occurs is a change in the abundance and/or diversity of the vectors. An increasing number of empirical studies have described heterogeneous effects of landscape anthropization on vector communities; therefore, it is difficult to have an overall picture of these effects on a global scale. Here, we performed a meta-analysis to quantify the impacts of landscape anthropization on a global scale on the presence/abundance and diversity of mosquitoes, the most important arthropods affecting human health. We obtained 338 effect sizes on 132 mosquito species, compiled from 107 studies in 52 countries that covered almost every part of the world. The results of the meta-analysis showed an overall decline of mosquito presence/abundance and diversity in response to urbanization, deforestation, and agricultural development, except for a few mosquito species that have been able to exploit landscape anthropization well. Our results highlighted that these few favoured mosquito species are those of global concern. They thus provide a better understanding of the overall effect of landscape anthropization on vector communities and, more importantly, suggest a greater risk of emergence and transmission of vector-borne diseases in human-modified landscapes.

Figure 5 in Anthropic action affects the cuticular chemical profile of social wasps

Figure 5. Ordering by Detrended Correspondence Analyses (Axes 1 and 2) based on the cuticular hydrocarbon profile of the samples of the 3 species whose colonies were nested in two types of environments. The points on Axis 1, between 0 and 50 on the left, represent compounds more characteristic of samples from more anthropized environments and between 100 and 150 on the right, from less anthropized environments.

Supplementary material: Mammal diversity responses to anthropic, environmental, and seasonal changes within Caatinga seasonal dry forest landscapes

Caatinga's conservation and biodiversity are threatened due to the intensification of anthropic activities and climate change. The mammals have different responses to seasonal and anthropic changes, however particularly in Caatinga, these effects are still poorly understood. We assessed the influence of anthropic (distance from urban areas and wind farms), environmental (distance from water), and seasonal (Normalized Difference Vegetation Index – NDVI and land surface temperature - LST) variables on the number of records and richness of medium and large-sized mammals in Brazilian Caatinga. We used camera traps in 2016/2017 and 2018/2019, estimated the variation (cv) of NDVI and LST, and generated Euclidean distance maps to anthropic and environmental variables at 250, 500, and 1000 m spatial scales. We performed Generalized Linear Models, used the Akaike information criterion, and calculated model averaging to assess the strength and direction of effect and the uncertainties of the winner models, respectively. The distance from wind farms and maximum LST had a noticeable effect on the number of records and total richness. The distance from wind farms had a negative effect on the records of Dicotyles tajacu and a positive effect on the records of Leopardus pardalis and richness. The maximum LST had a negative effect on the records of Leopardus pardalis and a positive effect on the records of Puma concolor and Cerdocyon thous. Our results emphasize that an unsustainable expansion of wind farms is likely to compromise mammal diversity. We found an opposite pattern for some species regarding LST. However, it is important to highlight that the conservation of vegetation areas on the top of mountains and springs, and the installation of artificial water sources are important strategies to mitigate the impacts of high temperatures on mammals' biodiversity in Caatinga.
