First evidence of yearly allochrony in a terrestrial vertebrate: A case study of an annual chameleon.
Article in Ecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Isolation through differences in reproductive timing, known as allochrony, is a unique life history trait that can lead to the separation of a population into two distinct populations. Yearly allochrony, where reproductive events are separated between years, is extremely rare and has been documented <10 times. It requires a single reproductive event at a fixed age and a life cycle of 2 years or more. Among terrestrial vertebrates, documented examples of yearly allochrony are nonexistent. Our study reveals that Chamaeleo chamaeleon musae possesses the potential for allochronic separation. These chameleons reproduce 1 year after hatching, with only 0.2% of the population surviving to a second reproductive season. Their eggs require 11 months to hatch. This combination of factors results in two distinct subpopulations: one that incubates eggs during even years while adults reproduce in odd years and another that follows the reverse pattern. This separation prevents intermixing between the two subpopulations. C. c. musae is currently the only known terrestrial vertebrate exhibiting yearly allochrony. Population and evolutionary ecologists must consider yearly allochrony when studying animal life cycles, given its significant implications for speciation, species conservation, and monitoring programs.
