First Evaluation of PRISMA Level 1 Data for Water Applications
-
This study presents a first assessment of the Top-Of-Atmosphere (TOA) radiances measured in the visible and near-infrared (VNIR) wavelengths from PRISMA (PRecursore IperSpettrale della Missione Applicativa), the new hyperspectral satellite sensor of the Italian Space Agency in orbit since March 2019. In particular, the radiometrically calibrated PRISMA Level 1 TOA radiances were compared to the TOA radiances simulated with a radiative transfer code, starting from in situ measurements of water reflectance. In situ data were obtained from a set of fixed position autonomous radiometers covering a wide range of water types, encompassing coastal and inland waters. A total of nine match-ups between PRISMA and in situ measurements distributed from July 2019 to June 2020 were analysed. Recognising the role of Sentinel-2 for inland and coastal waters applications, the TOA radiances measured from concurrent Sentinel-2 observations were added to the comparison. The results overall demonstrated that PRISMA VNIR sensor is providing TOA radiances with the same magnitude and shape of those in situ simulated (spectral angle difference, SA, between 0.80 and 3.39; root mean square difference, RMSD, between 0.98 and 4.76 [mW m−2 sr−1 nm−1]), with slightly larger differences at shorter wavelengths. The PRISMA TOA radiances were also found very similar to Sentinel-2 data (RMSD 3.78 [mW m−2 sr−1 nm−1]), and encourage a synergic use of both sensors for aquatic applications. Further analyses with a higher number of match-ups between PRISMA, in situ and Sentinel-2 data are however recommended to fully characterize the on-orbit calibration of PRISMA for its exploitation in aquatic ecosystem mapping.

First inventory of Ants (Hymenoptera: Formicidae) with detection of potentially invasive species in National Park of Ehotilés islands, Côte d’Ivoire
-
Estuarine and wetland ecosystems are becoming increasingly altered by the concentration of human population near the coastline. A major threat to biodiversity related to this is the introduction of invasive alien species. This is particularly the case for isolated ecosystems like islands where the invasion of non-native species is often harmful. The National Park of Ehotilés Islands is an archipelago of 6 islands and a RAMSAR site subjected to disturbances, namely agriculture, illegal fisheries, and tourism. These factors often act as an accelerator for the introduction of invasive species. However, there is a lack of research on insects, specifically ants, on these islands. This study aimed to inventory the present ant fauna and estimate the vulnerability to tramp and potential invasive ant species. Ants were collected using Winkler, pitfall, and funnel traps on five islands. In total, 76 ant species were recorded. These species are distributed into 20 genera and five subfamilies: Dolichoderinae (5 species), Formicinae (11 species), Myrmicinae (49 species), Ponerinae (11 species) and Proceratiinae (1 species). We also detected two tramp and potentially invasive species: the ghost ant Tapinoma melanocephalum and the big-headed ant Pheidole megacephala. Ant communities are dominated by six species, namely Odontomachus troglodytes, Oecophylla longinoda, Nylanderia lepida, Pheidole sp.2, Monomorium invidium, and the invasive ghost ant Tapinoma melanocephalum. This work is the first to inventory ants on the Islands of Ehotilés National Park and may serve as a basis for conservation decisions as it demonstrates that this park is not spared from the introduction of invasive ant species.

Soil‑litter arthropod communities under pasture land use in southern Rwanda
-
Land use change caused by human activities is the main driver of biodiversity loss and changes in ecosystem functioning. However, less is known about how the conversion of a natural to pasture land favour the biological diversity of soil-litter arthropods to advance efective conservation plans and management systems. To fll the gap, this study focussed on soil-litter arthropod communities under a pasture land use in southern Rwanda. Data have been collected using pitfall traps and hand collection between April and June 2021. Sampled specimens of soil-litter arthropods have been identifed to order and family levels by using dichotomous keys. Further, the species name was given when the identifcation key was available, while the morphological description was provided in absence of the identifcation keys. Results indicated a total of 3013 individuals of soil-litter arthropods grouped into 3 classes, 13 orders, 46 families and 87 morpho-species. Coleoptera showed a high number of families, while higher abundance and the number of morpho-species were found for ants (Hymenoptera: Formicidae). Higher abundance of sampled soil-litter arthropods is a sign that the studied area ofers suitable habitat for soil-litter arthropods. However, less abundance found for some groups of soil-litter arthropods might be infuenced by the used sampling techniques which were not appropriate for them. We recommend surveys using multiple sampling techniques to maximize chances of capturing a wide range of soil-litter arthropods

Local knowledge of the impact of uncontrolled fires on ecosystem services: a case study in the Pendjari Biosphere Reserve in Benin
-
Ecosystem services are fundamental to people and are undergoing many threats such as uncontrolled fire. Local knowledge has been widely used to guide management decisions for plant biodiversity. Therefore, we assessed the knowledge of the people of Pendjari Biosphere Reserve (PBR) on the impact of fire on ecosystem services (ES). A semi-structured questionnaire with three fire impact levels (no, low and high) was used to interview 150 randomly selected households in four ethnic groups. The generalised linear model (GLM) was performed on the relative frequency of quotations to assess the effect of ethnic group, age and sex for each impact level of fire on ES and also to test the interaction among the considered factors. The local people reported that uncontrolled fire causes damage to many provisioning ES. The local knowledge concerning the impact of fire on ES was affected significantly (p < 0.0001) by ethnic group, age and sex irrespective of the impact level of fire on ES. Moreover, there was no significant interaction among the considered factors. The studied factors are benchmarks to be integrated into awareness and preservation measures of ES to mitigate the impact of uncontrolled fire practices in the study area.
