name: gcb-literature-positioning
description: Use when positioning a Global Change Biology (GCB) manuscript in the literature so it reads as a global-change advance, not a local report. GCB readers span ecology, biogeochemistry, and Earth-system science, so the paper must engage the cross-system literatures it speaks to. Structures positioning; it does not fabricate citations.

# Literature Positioning (gcb-literature-positioning)

GCB is read across **ecology, biogeochemistry, ecosystem science, and Earth-system / climate-impacts**
communities. A submission must show it knows the **global-change** literature on its driver and
response — not just the narrow subfield where the data were collected. This skill positions the
contribution so reviewers see the gap and the advance.

## When to trigger

- Writing the introduction's "what is known / what is missing" framing
- Reconciling a finding with prior global-change studies (and apparent contradictions)
- Building a Research Review's coverage and argument
- A reviewer said the framing is "too local" or "misses key literature"

## How to position for GCB

1. **Anchor on the driver-response literature**, not only the local system. Cite the global-change
   studies a GCB reader expects (warming experiments, FACE/eCO2, N-deposition, range shifts, flux
   syntheses), then show your gap.
2. **Speak across systems.** A terrestrial result should acknowledge whether the mechanism is expected
   to hold in aquatic/marine systems and vice versa; GCB rewards generality.
3. **Engage the synthesis literature.** Meta-analyses and model-intercomparison papers often define the
   consensus you are confirming, extending, or challenging — engage them explicitly.
4. **Be honest about contradictions.** If your result conflicts with a prior study, say so and explain
   the mechanism (scale, system, duration, design), rather than ignoring it.
5. **Position the mechanism, not just the magnitude.** The contribution is usually *why* a response
   occurs or *how* it scales — make that the gap.

## Diagnosing the framing gap

GCB's cross-disciplinary readership means a paper can be well-cited inside its subfield yet read as
parochial to the journal. This table maps the symptom an editor or referee flags to the positioning
move that closes it.

| Symptom in the draft | What it signals | Positioning fix |
|----------------------|-----------------|-----------------|
| Only single-taxon citations | Subfield framing, not global-change | Anchor on the driver-response literature across taxa |
| No meta-analysis or MIP cited | Unaware of the consensus | Engage the synthesis that defines the baseline |
| "Novel" for a known response | Local novelty mistaken for advance | Reframe the gap as mechanism or scaling, not first sighting |
| Contradiction unmentioned | Selective reading | Name the conflicting study and explain it mechanistically |
| Terrestrial-only with no marine nod | Generality unproven | State whether the mechanism is expected across systems |

## Worked micro-example (illustrative)

A species-range-shift model predicts an illustrative 180 km poleward shift of a montane plant by 2070.
A local framing cites only regional floristic surveys. A GCB framing instead anchors on the range-shift
synthesis literature (which reports a mean terrestrial shift of an illustrative ~17 km per decade), shows
that this taxon shifts faster because of a dispersal-limitation mechanism the syntheses average over, and
notes whether the same lag is documented for marine ectotherms. The gap is now mechanistic and
cross-system, not "a new record for our mountains." Numbers illustrative.

## Referee pushback patterns and the fix

- "Too local; misses key literature" → replace site-specific citations with the driver-response and
  synthesis literatures a GCB reader expects.
- "This is already known from the meta-analysis" → reframe the contribution as the mechanism or scaling
  the synthesis cannot resolve.
- "Ignores contradictory evidence" → engage the conflicting result and reconcile it by scale, duration,
  system, or design.

## Anti-patterns

- Citing only the local/regional or single-taxon literature on your study system
- Ignoring large syntheses / model-intercomparisons that already address your question
- Treating a known global-change response as novel because it is new *for your site*
- Burying contradictory prior findings instead of engaging them
- A citation pile with no argument about where the field is stuck

## Output format

```
【Driver-response literature】key prior global-change work engaged
【Cross-system reach】does the mechanism travel beyond your system? [Y/N/—]
【Synthesis engaged】relevant meta-analyses / MIPs cited?
【Gap】what is missing / contested → your advance
【Contradictions】reconciled with mechanism? [Y/N/NA]
【Next】gcb-study-design
