“…the communication tower lights were one of the most important factors causing collisions of birds at night [2]. Noise is derived from the Latin word "nausea" implying 'unwanted sound' or 'sound that is loud, unpleasant or unexpected [3]. If sound is referred to as noise pollution, it is no wonder that it is a sound that can harm humans and animals.…”

It is common knowledge that human society is developing faster and faster nowadays. As human society is developing, the cities are expanding. As the cities are expanding, more and more people are now in the city. To help these people live a better life, more and more resources are produced. After producing most of the products nowadays, there comes pollution. In this way, pollution is getting more and more serious. All of the pollution that is already in a city do not only affect human but also affect birds. One of the most common non pollution is air pollution, almost every city in the world has air pollution. But there are also two other kinds of pollution that is also harming the society and the animals in a serious way. They are light pollution and sound pollution. This passage focuses on these two types of pollution. Light pollution will cause birds to sleep less and may affect their migration way. The birds may be killed halfway on migration way because of the light may lead them to a loss of direction. Sound pollution also reduces the bird sleeping quality. This kind of pollution also cause birds to get food more difficult. By analyzing the effects of these pollution, some ways to help birds may be figured out.

An effective method for identifying species and evaluating the effects of changes caused by humans on specific species is the application of species distribution modelling (SDM) in desert environments. The fact that many dry lands and deserts throughout the world are situated in inhospitable regions may be the reason why such applications are still infrequently used on plant species in Egypt's Mediterranean region. Henceforth, the current study aims to map species richness and weighted endemism of Mediterranean endemics in the Mareotis subsector in Egypt and determine the environmental variables influencing distribution of these taxa. We produced a map of species distribution range using Ensemble SDMs. Further, stacked machine learning ensemble models derived from Random Forest (RF) and MaxEnt models were applied on 382 Mediterranean endemics distribution data to estimate and map diversity and endemism using two indices: species richness (SR) and weighted endemism index (WEI). The best models for ensemble modelling were chosen based on Kappa values and the Area Under the Receiver Operator Curve (AUC). The results showed that the models had a good predictive ability (Area Under the Curve (AUC) for all SDMs was > 0.75), indicating high accuracy in forecasting the potential geographic distribution of Mediterranean endemics. The main bioclimatic variables that impacted potential distributions of most species were wind speed, elevation and minimum temperature of coldest month. According to our models, six hotspots were determined for Mediterranean endemics in the present study. The highest species richness was recorded in Sallum, Matrouh wadis and Omayed, followed by Burg El-Arab, Ras El-Hekma and Lake Mariut. Indeed, species richness and endemism hotspots are promising areas for conservation planning. This study can help shape policy and mitigation efforts to protect and preserve Mediterranean endemics in the coastal desert of Egypt. These hotspots should be focused on by policy makers and stakeholders and declared as protectorates in the region. The largest number of species per area would be protected by focusing primarily on the hotspots with high species richness.
