Analysing ecological networks of species interactions (2018, background): “There is a long-standing dispute (Post, 2002) among ecologists as to whether ‘arrows’ in networks should represent biomass flow (e.”
Spatial hierarchical approach in community ecology: a way beyond high context-dependency and low predictability in local phenomena (2004, background): “The properties of food web statistics strongly depend on web size, which depend on the spatiotemporal scale of observations (e.g., Martinez 1993; Closs and Lake 1994; Martinez and Lawton 1995; Tavares-Cromer and Williams 1996; Martinez and Dunne 1998; Post 2002 ).”
A preliminary analysis of the correlation of food-web characteristics with hydrology and nutrient gradients in the southern Everglades (2006, methodology): “We used simple two-end-member-mixing models (reviewed in Post, 2002b) to estimate indices of detritivory (ID) and trophic position for each study site at both sampling seasons. d13C enriches minimally ( 0–1&) as it moves through food webs (DeNiro & Epstein, 1978; Vander Zanden & Rasmussen, 2001;…”

The problem of isotopic baseline: Reconstructing the diet and trophic position of fossil animals (2011, methodology): “These taxa are good temporal integrators and adequately reflect the spatial variability of the primary producers on which they feed in both lacustrine (Post, 2002b) and marine systems (Fig.”
Freshwater food webs: towards a more fundamental understanding of biodiversity and community dynamics (2012, background): “…loops (e.g. Williams & Martinez, 2000, Dunne, Williams & Martinez, 2004; Vermaat, Dunne & Gilbert, 2009); food chain lengths and trophic level (e.g. Post 2002, Williams and Martinez 2004); degree distributions (e.g. Dunne et al., 2002a; Stouffer et al., 2005); small interaction motifs (Stouffer et…”
Trophic Interaction Cycles in Tundra Ecosystems and the Impact of Climate Change (2005, background): “Low primary productivity may restrict food chain length ( Post 2002 ), and it has been suggested that the northernmost higharctic tundra may not be productive enough to provide subsistence for any herbivores (Oksanen and Oksanen 2000).”
Comparison of methods to determine algal δ13C in freshwater (2008, methodology): “1999, Matthews and Mazumder 2003) and as baselines to infer food chain length (Post 2002).”
On the relationship between trophic position, body mass and temperature: reformulating the energy limitation hypothesis (2007, unknown): “however, the theoretical support for this hypothesis is weak (Post 2002), and has been challenged on”
Food web structure and body size: trophic position and resource acquisition (2010, background): “…that system size (e.g. pond area), through its effect on species diversity (MacArthur and Wilson 1967) and maximum body size (Marquet and Taper 1998), should affect food chain length, as has been observed elsewhere (Briand and Cohen 1987, Spencer and Warren 1996, Post et al. 2000, Post 2002).”
Cascading extinctions as a hidden driver of insect decline (2020, background): “As mentioned earlier, top predators and other species found at the higher levels of food chains are particularly vulnerable to extinction (Post, 2002).”

Foodweb structure in a tropical Asian forest stream (2004, background): “High disturbance, low algal food resources (Jaarsma et al. 1998, Townsend et al. 1998) and/or small ecosystem size (Post 2002) might reduce foodchain length.”
Enhanced bioaccumulation of mercury in deep-sea fauna from the Bay of Biscay (north-east Atlantic) in relation to trophic positions identified by analysis of carbon and nitrogen stable isotopes (2012, unknown): “Indeed, the use of these ecological tracers is principally based on the fact that 1) primary producers of an ecosystem generally present different isotopic compositions, due to the different nutrients fixed and the biochemical cycle they use for photosynthesis (Peterson and Fry, 1987; France, 1995);”
Network ecology: topological constraints on ecosystem dynamics (2004, background): “It was shown that if chains are long, abundances vary more (137), there are more extinction events (137), it is easier to cause disturbances (65) and regeneration is slower (131).”
The trophodynamics of marine top predators: Current knowledge, recent advances and challenges (2015, background): “…and export processes (e.g. vertical flux; Cohen et al., 2003; Kerr and Dickie, 2001), differences in food chain length resulting from the size structure of the primary producers have significant implications for the efficiency of energy transfer to top predators (Dickman et al., 2008; Post, 2002).”
The Network Structure of Food Webs (2005, unknown): “This research reflects the understanding that food-chain length, or “the number of transfers of energy or nutrients from the base to the top of a food web,” is a central characteristic of ecological communities due to its impact on ecosystem functioning, such as nutrient and carbon cycling, contamin”

Embracing variability in amino acid δ15N fractionation: mechanisms, implications, and applications for trophic ecology (2016, background): “…central challenge to interpreting bulk tissue δ15N measurements, particularly of upper trophic- level consumers, is in determining whether consumer bulk δ15N values reflect variability in the δ15Nbaseline, trophic positions, Δ15NC-D values, or some combination of all of these factors (Post 2002b).”
