Vai trò của khoảng thời gian lửa quay trở lại và mùa đốt trong động lực học cây chết đứng tại rừng thông chẻ Florida phía Nam
Tóm tắt
Các cây chết đứng, hay còn gọi là cây snag, là một yếu tố habitat quan trọng cho nhiều loài động vật. Trong nhiều hệ sinh thái, lửa là một yếu tố chính điều khiển động lực học quần thể cây snag vì nó có thể tạo ra và tiêu hủy các cây snag. Mục tiêu của nghiên cứu này là xem xét cách mà sự biến đổi của hai thành phần chính trong chế độ lửa—khoảng thời gian quay trở lại của lửa và mùa đốt—ảnh hưởng đến động lực học quần thể cây snag. Sử dụng thiết kế nhân tố, chúng tôi đã phơi bày các ô 1 ha, nằm trong các đơn vị đốt lớn hơn ở rừng thông chẻ Florida phía Nam (
