TLDR
In the field of ecology, there are two long-standing ways to study large ecosystems such as lakes, forests, and salt-marsh estuaries: the holo-logic approach and the merological approach as mentioned in this paper.Abstract:
Ecologists have two long-standing ways to study large ecosystems such as lakes, forests, and salt-marsh estuaries. In the first, which G. E. Hutchinson has called the holological approach, the whole ecosystem is first studied as a "black box," and its components are investigated as needed. In the second, which Hutchinson has called the merological approach, the parts of the system are studied first, and an attempt is then made to build up the whole from them. For long-term studies, the holological approach has special advantages, since the general patterns and tentative hypotheses that are first worked out help direct attention to the components of the system which need to be studied in greater detail. In this approach, teams of investigators focus on major func tions and hypotheses and thereby coordinate their independent study efforts. Thus, although there have been waves, as it were, of investigators and graduate students working on different aspects of the Georgia salt-marsh estuaries (personnel at the Marine Institute on Sapelo Island changes every few years), the emphasis on the holo logical approach has resulted in a highly differentiated and well-coordinated long-term study. Very briefly, the history of the salt-marsh studies can be outlined as follows. First, the general patterns of food chains and other energy flows in the marshes and creeks were worked out, and the nature of imports and exports to and from the system and its subsystems were delimited."read more

Ecosystem-level patterns of primary productivity and herbivory in terrestrial habitats
TL;DR: Evidence is presented that herbivore biomass, consumption and produc-tivity are closely correlated with plant productivity, suggesting that the latter is a principal integrator and indicator of functional processes in food webs.

Ichnology: Organism-Substrate Interactions in Space and Time
TL;DR: In this article, a detailed analysis of the ichnology of a range of depositional environments is presented using examples from the Precambrian to the recent, and the use of trace fossils in facies analysis and sequence stratigraphy is discussed.

Comparative ecology of tidal freshwater and salt marshes
TL;DR: Historically, tidal freshwater environments have been ignored by limnologists because of the presence of oceanic tidal influence, and neglected by marine ecologists because they are bathed by freshwater and inhabited primarily by freshwater organisms.

Sulfur, carbon, and nitrogen isotopes used to trace organic matter flow in the salt-marsh estuaries of Sapelo Island, Georgia1
TL;DR: In this article, the stable isotopes of sulfur, nitrogen, and carbon were used to trace organic matter flow in salt marshes and cstuarinc waters at Sapelo Island, Georgia.

The Consumption and Utilization of Food by Insects
TL;DR: It seems apparent that adaptive nutritional differences must be sought on a quantitative level and that a meaningful comparative nutrition of insects will not emerge until quantitative studies are emphasized.

TL;DR: The data are consistent with the view that N/ Sub 2/O is an obligatory intermediate in the reduction of NO/sub 2//sup -/ to N/ sub 2/ in all of the three organisms studied.

The Importance of Predation by Crabs and Fishes on Benthic Infauna in Chesapeake Bay
TL;DR: Severe predation, and the rapid growth, short generation times, and rapid turnover rates of constituent populations suggest that such infaunal communities, despite a low stand- ing crop, are an important food source for predator species important to man.
