Review Process (gcb-review-process)

GCB is selective and desk-rejects a large share of submissions before review. Knowing how it is judged — what triggers desk rejection, who reviews, and what decisions look like — lets you prepare a manuscript that survives screening and convinces reviewers. Verify volatile specifics on the official page before submission.

When to trigger

• Setting expectations before submitting
• Diagnosing why a paper might be desk-rejected
• Anticipating reviewer concerns to pre-empt in the manuscript
• Interpreting a decision letter (then route to gcb-revision-and-rebuttal)

How GCB judges a paper

1. Editorial / desk screening (high bar). Editors screen first for scope fit (a mechanistic global-change → biological-response advance), significance / broad relevance, and basic soundness. A large fraction is desk-rejected quickly; a poor scope/significance fit is the most common cause.
2. Expert peer review. Matched experts assess mechanism, design, inference, uncertainty, and reproducibility; live-check current anonymity / transparent-review options on the official page.
3. Reviewer access to data. Reviewers may request access to data during evaluation — have the archive/availability ready.
4. Decision categories. Accept (rare on first pass), minor / major revision, or reject; editors weigh reviewer assessments and fit.

Prepare for the way it is judged

• Make the scope fit and significance unmistakable in the title, abstract, and cover letter.
• Pre-empt the predictable reviewer concerns: scale/extrapolation, confounding/pseudoreplication, uncertainty, and reproducibility.
• Have data and code archived (or staged) so a reviewer request is trivial to satisfy.

Desk-reject triggers and how to neutralize them

The editorial screen is where most submissions end. Map the common trigger to the pre-submission move that removes it, before the manuscript ever reaches a reviewer.

Desk-reject trigger	Why it fires	Neutralizing move
Scope mismatch	Reads as regional/conservation, not global-change	Lead title/abstract with driver → response mechanism
Thin significance	Increment too small for a broad-readership venue	State magnitude and cross-system relevance up front
Scale overreach	Plot result framed as global	Match the claim to the evidence; flag extrapolation
Missing required element	No graphical abstract or data statement	Complete both before submitting
Reproducibility gap	No archiving plan visible	Stage the DOI deposit and say so

Worked micro-example (illustrative)

A range-shift modelling paper is screened. The editor checks three things in order: does it test a global-change driver (yes — warming), is the advance broad (the mechanism generalizes across montane floras), and is it sound enough to review (design and uncertainty look defensible). It passes to two reviewers with matched expertise (illustrative), one a biogeographer and one a modeller. The modeller asks for the projection ensemble; because the code is already staged for archiving, the request is trivial to satisfy. Had the paper led with "a new record for our region," it would likely have stopped at the desk. Reviewer counts and roles are illustrative; confirm the current model on the official page.

What expert reviewers reliably probe

• Whether a correlative pattern is being presented as a mechanism.
• Whether plot-to-biome scaling carries propagated uncertainty.
• Whether confounding or pseudoreplication undermines the causal claim.
• Whether the archived data and code actually reproduce the headline result.

Anti-patterns

• Submitting a local/conservation-framed paper that fails the global-change scope screen
• Assuming review fixes a significance problem (desk screening catches it first)
• Ignoring uncertainty/reproducibility that expert reviewers will flag
• Being unprepared for a reviewer's request to access the data

Output format

【Desk-screen risk】scope + significance unmistakable? [Y/N → why]
【Reviewer concerns】scale / confounding / uncertainty / reproducibility pre-empted?
【Review model】expert review; anonymity / transparent-review option live-checked? [Y/N]
【Data ready for reviewers】[Y/N]
【Decision likely】revision categories anticipated
【Next】gcb-submission (pre-decision) or gcb-revision-and-rebuttal (post-decision)
