Description
Objective: To determine the relationship between changes in ecosystems and agrosystems provoked by human intervention and the alpha, beta and gamma diversity of the Diplopoda in the middle basin of the Otún river. Materials and methods: In this research we used a stratified systematic design with seven sampling windows and 16 sampling points. Millipedes were divided into families and morphotypes to calculate the alpha, beta and gamma diversity related to the heterogeneity of land uses. Results: We identified 35 morphotypes from 12 families and five orders. Alpha diversity of Diplopoda revealed significant differences between land uses (P <0.05) and a decrease of richness from preserved areas to transformed areas by human activity. A high number of exclusive morphotypes were found in forest relicts and fallow with low species turnover between them, while the pastures, crop fields and plantations presented similar numbers of morphotypes but the species turnover between them was high (complementarity > 85%) in spite of the low diversity in the land uses, which determined the high contribution of the beta diversity to the gamma diversity of the landscape. Conclusion: The heterogeneity of land uses showed that the changes modify the structure of diversity in Diplopoda with gradients diverging from the preserved ones to the highly transformed ones.
Key words: alpha, beta, gamma diversity, Colombian Andes, soil Diplopoda.

< strong >< strong>الهدف :لتحديد العلاقة بين التغيرات في النظم الإيكولوجية والنظم الزراعية الناجمة عن التدخل البشري وتنوع ألفا وبيتا وغاما في ديبلوبودا في الحوض الأوسط لنهر أوتون. المواد والأساليب: في هذا البحث استخدمنا تصميمًا منهجيًا طبقيًا مع سبع نوافذ لأخذ العينات و 16 نقطة لأخذ العينات. تم تقسيم الدودة الألفية إلى عائلات وأنماط مورفولوجية لحساب تنوع ألفا وبيتا وغاما المرتبط بعدم تجانس استخدامات الأراضي. النتائج:حددنا 35 نمطًا مورفولوجيًا من 12 عائلة وخمس رتب. كشف تنوع ألفا من Diplopoda عن اختلافات كبيرة بين استخدامات الأراضي (P< 0.05) وانخفاض في الثراء من المناطق المحمية إلى المناطق المحولة بسبب النشاط البشري. تم العثور على عدد كبير من الأنماط الشكلية الحصرية في بقايا الغابات والراحة مع انخفاض دوران الأنواع بينهما، في حين أن المراعي وحقول المحاصيل والمزارع قدمت أعدادًا متشابهة من الأنماط الشكلية ولكن دوران الأنواع بينهما كان مرتفعًا (التكامل > 85 ٪) على الرغم من التنوع المنخفض في استخدامات الأراضي، مما حدد المساهمة العالية لتنوع بيتا في تنوع نطاق المناظر الطبيعية. الاستنتاج: أظهر عدم تجانس استخدامات الأراضي أن التغييرات تعدل بنية التنوع في Diplopoda مع تباين التدرجات عن تلك المحفوظة إلى تلك التي تم تحويلها بشكل كبير.
