Ecological Stability pp Cite as. Elton gave as one reason why more complex ecosystems might be expected to be more stable than simpler ones, that simple, two species, ecosystem models tend to be unstable. As May , , has pointed out, such an argument is only valid if it may be shown that more complex ecosystem models, involving more species with a greater degree of food web linkage, exhibit greater stability than simpler ones.

The diversity of life and its organization in networks of interacting species has been a long-standing theoretical puzzle for ecologists. Spatial dynamics may be stabilizing and thus explain high community diversity, yet existing theory on spatial stabilization is limited, preventing comparisons of the role of dispersal relative to species interactions.

Understanding the mechanisms responsible for stability and persistence of ecosystems is one of the greatest challenges in ecology. Robert May showed that, contrary to intuition, complex randomly built ecosystems are less likely to be stable than simpler ones. Here we perform a stability analysis of quantitative food webs sampled worldwide.

Stability and Complexity in Model Ecosystems

May challenged this view in the 'sc by showing mathematically that in model ecosystems stability decreases with the number of species in a community and can therefore not be regarded as a straightforward consequence of complexity. To derive this result May investigated the stability properties of aRobert M.

No complexity–stability relationship in empirical ecosystems

Свет внутрь проникал через маленькие амбразуры-окна, расположенные по спирали через каждые сто восемьдесят градусов. Он в ловушке. Дэвид Беккер умрет. Халохот поднимался вверх с пистолетом в руке, прижимаясь вплотную к стене на тот случай, если Беккер попытается напасть на него сверху. Железные подсвечники, установленные на каждой площадке, стали бы хорошим оружием, если бы Беккер решил ими воспользоваться. Но если держать дистанцию, можно заметить его вовремя. У пистолета куда большая дальность действия, чем у полутораметрового подсвечника.

Мидж развернулась и направилась к двери. Откуда ни возьмись появился Бринкерхофф и преградил ей дорогу. - Куда держишь путь. - Домой! - солгала Мидж. Бринкерхофф не уходил с дороги. - Это тебе велел Фонтейн? - спросила .


Stability and complexity in model ecosystems, by Robert M. May*. C. W.D. PEARE. S.O.E.C. Luxemburg. The theme of this work is admirably described in its title.

Introduction

Я сказал ей, что даю пятьдесят, но она хотела. Ей надо было выкупить билет на самолет - если найдется свободное место перед вылетом. Беккер почувствовал, как кровь отхлынула от его лица. - Куда. - В ее трахнутый Коннектикут.  - Двухцветный снова хмыкнул.

Stability and Complexity in Model Ecosystems played a key role in introducing nonlinear mathematical models, along with the study of deterministic chaos, to ecologists—as science writer James Gleick would chronicle in his best-seller Chaos.

At the same time, May ( May (, tied community stability to species diversity, number of interactions within a community, and interaction.
