“…Coastal areas such as river deltas, lagoons etc. usually support high levels of bird diversity in the Mediterranean zone, e.g., at Ebro Delta (Spain) where around 140 bird species in total were recorded during the years 2005-2015 (Belmar et al 2019), as well as in the National Park of Axios -Loudias -Aliakmon Delta in northern Greece where 71 species were recorded from 2012 until 2017 (Soulopoulou et al 2020).…”

Coastal wetlands are considered as systems of high avian diversity and are usually used for livestock production throughout the world. In this study, the diversity and seasonal abundance of avian species were monitored for two years on a monthly basis in a coastal grazing land in Evros Delta (Greece). The effects of livestock (cattle) presence and different classes of vegetation cover on the number of bird species were also investigated. A total of 96 bird species belonging to 29 families were recorded. The most commonly encountered species was the Eurasian skylark Alauda arvensis. The cattle presence was not significantly correlated (p>0.05) with the abundance of recorded bird species. On the contrary, patches with vegetation cover 25.1 - 50.0% and 50.1 - 75.0 % were used by more bird species in relation to patches with cover ≤25.0% or >75.0%. We concluded that the use of livestock grazing to preserve the desired vegetation cover (25 – 75%) is a promising management tool.

“…In previous works we have detected alterations in avian biodiversity throughout the last years in a representative Natura 2000 wetland in Northern Greece [11]. The objective of the current work is the detection of the existence of interrelationships between some of the most important environmental drivers, namely temperature and rain levels and the avian biodiversity in a Mediterranean like Natura 2000 wetland.…”

“…Three biodiversity indexes were estimated based on the bird counts recorded including the Shannon diversity, Simspons dominance index and the Berger -Parker index [11]. The Shannon diversity function, is a measure of the information necessary to specify an assemblage and probably the most common biodiversity measure.…”

In this work we address the question of how certain climatic variables may be significant related to alterations of avian biodiversity in a semi-agricultural Natura wetland side in Northern Greece. In particular, we examine the interplay between temperature, relative humidity and three different bird biodiversity indexes, including Shannon Entropy, Simpson's dominance (evenness) index and the Berger-Parker index. By using different modeling approaches, parametric and nonparametric multivariate models, we make effort to get a consensus on the interrelationships between climate and avian biodiversity. In particular, we show that in most cases nonlinear models and surface-plot analysis methodology, are able to capture the relation of a considerable increase in the estimated biodiversity indexes with increased temperatures and rain levels. Thus, biodiversity is to a significant extent affected by the aforementioned climate factors at a proximate level involving synergies between the different climate factors. Revealing potential interrelationship between biodiversity and climate drivers although is a complex-even though challenging-task, contributing to our understanding of the mechanisms connecting climate change with ecosystem functioning. Moreover, a better understanding of biodiversity functioning in relation to climate is essential for biodiversity awareness and the design of effective biodiversity-related conservation management policies.

“…To mitigate the decline in biodiversity, Europe has established the Natura 2000 network to protect threatene species by providng a core of breeding and resting sites [3]. The network stretches across all European member states with the aim to ensure long term sustainability of species and habitats, liseted under the Birds and Habitats directives.…”

“…The network stretches across all European member states with the aim to ensure long term sustainability of species and habitats, liseted under the Birds and Habitats directives. Yet, in the last 4 decades, birdsbut also the biodiversity of Europe's agro-ecosystems as a whole -have undergone a dramatic decline, which is mainly due to the intensification of agriculture and climate change [3]. Furthemore, the distribution of many species in Europe is expected to be influenced due to identisification of agriculture and related human activites.…”

In this study we explore for the first time the combined effect of climate variables and remote sensing land cover indicators on bird richness in a representative wetland location of the Thermaikos gulf Natura 2000 protected area in Northern Greece. In particular the association between bird diversity and climate, as well as remote sensed land cover indices was explored for seven successive seasons using correlation analysis and a Cox-Box transformed multivariate linear model. Three climate variables were tested, mean temperature, rain level and mean relative humidity and three land cover indices, the Normalized difference index (NDVI), the atmospheric resistance vegetation index (ARVI) and an agricultural band combination index (ABCI). Among the environmental drivers explored, temperature, rain levels and ABCI were significantly correlated to bird richness in contrast to NDVI and ARVI which showed a lower correlation, while relative humidity displayed the poorest correlation. Thus, temperature, rain levels and agricultural intensity significantly influenced bird composition. Additionally, the multivariable linear model indicates that temperature, rain levels and ABCI have a statistically significant effect (p<0.05) on bird species richness accounting for 73,02% of data variability. Based on the overall model results and the related 3D contour plot simulation we can conclude that in general, bird species richness increases with an increase in temperature and Rain, as well as with a decrease in agricultural intensity (ABCI). Understanding the factors that can affect bird biodiversity of species is of great importance in ecosystem management and species conservation.
