This decline is worrying because these organisms perform essential ecological functions: pollination, natural pest control, recycling of organic matter, etc.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The suspected causes:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two factors are often cited:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The simplification of agricultural landscapes: disappearance of hedges, homogenization of crops, reduction of semi-natural environments.<\/li>\n\n\n\n<li>The use of pesticides, particularly insecticides, which directly or indirectly affect many species.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">However, other agricultural practices (grass management, type of tillage, irrigation, etc.) can also influence these communities, but their effects are less well known and may vary depending on the landscape context.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What the thesis seeks to understand:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Based on a dataset collected over several years in different orchards, this research aims to study:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The diversity of species present (taxonomic diversity),<\/li>\n\n\n\n<li>The ecological roles they fulfill (functional diversity),<\/li>\n\n\n\n<li>How arthropod assemblages change from one orchard to another, in relation to local agricultural practices and the surrounding landscape.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is therefore not just a question of measuring \u201chow many\u201d species are present, but how these communities are constructed, and what factors favor or limit certain species or ecological functions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A better understanding of these mechanisms will enable us to:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Identify concrete levers for action at the plot level (e.g., vegetation cover management, reduction of inputs, etc.),<\/li>\n\n\n\n<li>Guide the development of agricultural landscapes (e.g., maintenance of hedges, mosaic of environments, etc.).<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The ultimate goal is to support agricultural practices that promote biodiversity while sustaining the sustainability of fruit production systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2025-2028<\/p>","protected":false},"excerpt":{"rendered":"<p>\u201cDeterminants of taxonomic and
