3 mar 2004 · The biological communities within lakes may be organized conceptually into food chains and food webs to help us understand how the ecosystem functions (Figures 12 and 13). The simplest illustration of the organization of the organisms within an ecosystem is the ecological pyramid (Figure 14).
11 gru 2017 · a Food chain length is related to ecosystem volume in oligo- and mesotrophic lakes (dashed line), but not in eutrophic lakes (solid line shown for demonstrative purposes).
29 cze 2000 · We estimated food-chain length in 25 northern temperate lakes ranging in volume from 3.8 × 10 5 to 1.7 × 10 12 m 3, and ranging in total phosphorus from 2.6 to 230 µg l-1.
19 paź 2017 · However, as we shall see, the pelagic zone of a waterbody is closely linked to the more structurally complex littoral and benthic habitats, as well as to the microbial components of the food web. Before we dig deeper into these links, we will examine the intriguing roots of modern food web theory.
5 mar 2022 · Food webs are important for predicting climate change impacts (IPCC 2019) and forecasting life shifts in a lake. Differences in quantity and quality of the food supply in Lake Alchichica’s communities lack updated direct evidence.
1 sty 2020 · In Paul Lake, the reference lake, productivity varied from year to year, illustrating the effects of climatic factors and the natural dynamics of unmanipulated food web interactions.
10 mar 2016 · Toward this goal, we discuss empirical patterns in the structure of lake food webs to suggest that ecosystems change consistently, from individual traits to the structure of whole food webs, under changing environmental conditions.
