Dấu ấn của các tương tác gián tiếp trong mạng lưới kiến–thực vật được trung gian bởi tài nguyên ở các cấp độ tổ chức mạng lưới khác nhau
Oecologia - 2024
Tóm tắt
Các tương tác gián tiếp có vai trò then chốt trong sự tiến hóa của các loài tương tác và sự tập hợp của các quần thể và cộng đồng. Tuy nhiên, mặc dù gần đây đã được nghiên cứu trong mối quan hệ tương hỗ giữa thực vật và động vật ở cấp độ cộng đồng, các tương tác gián tiếp vẫn chưa được nghiên cứu trong những mối quan hệ tương hỗ trung gian tài nguyên giữa các cá thể thực vật chia sẻ các loài động vật khác nhau làm đối tác trong một quần thể (tức là, các mạng lưới dựa trên cá thể). Trong nghiên cứu này, chúng tôi đã phân tích một mạng lưới dựa trên cá thể giữa kiến và thực vật để đánh giá cách mà các thuộc tính của tài nguyên ảnh hưởng đến các mô hình tương tác gián tiếp và cách mà sự thay đổi trong các liên kết gián tiếp để lại dấu ấn trong mạng lưới qua nhiều cấp độ tổ chức mạng. Sử dụng các phương pháp phân tích bổ sung, chúng tôi đã mô tả các mô hình của các tương tác gián tiếp ở quy mô vi, vĩ mô và đại quy mô. Chúng tôi dự đoán rằng các cây cung cấp mức lượng và chất lượng đường mật trung bình sẽ tương tác với nhiều quần thể kiến đa dạng hơn. Sự gia tăng số lượng các loài kiến sẽ tạo ra tiềm năng cao hơn cho các tương tác gián tiếp ở tất cả các quy mô được đánh giá. Chúng tôi phát hiện rằng các thuộc tính của đường mật đã điều chỉnh các mô hình tương tác gián tiếp của các cá thể thực vật share các đối tác tương hỗ, để lại dấu ấn qua các quy mô mạng khác nhau. Theo hiểu biết của chúng tôi, đây là nghiên cứu đầu tiên theo dõi các tương tác gián tiếp tại nhiều quy mô trong một mạng lưới dựa trên cá thể. Chúng tôi cho thấy rằng các đặc điểm chức năng của các loài tương tác, chẳng hạn như các thuộc tính của đường mật, có thể dẫn đến những thay đổi trong các tương tác gián tiếp, có thể được theo dõi qua các cấp độ tổ chức mạng khác nhau được đánh giá.
