Latitude is known to deeply affect life with effects generalizable into ecological rules; the increasing species diversity toward tropics is the most paradigmatic. Several hypotheses tested patterns of biotic interactions’ intensity along latitude. Negative interactions (i.e. competition and predation) are expected to be among the processes that produce checkerboard distribution of species. However, no relationship between checkerboardness and latitude has been uncovered. We tested Odonata assemblages worldwide for segregation patterns using a faunistic dataset (395 species arranged in 386 natural communities) spanning a wide latitudinal range (87°). We used co-occurrence analyses (C-score index and Standardized Effect Size) as an estimate of checkerboardness then correlated the occurrence of segregation to latitude. Odonata followed the Latitudinal Diversity Gradient at the regional scale (i.e. country scale) within our analyzed assemblages spanning, whereas local richness (i.e. community scale) did not follow the same pattern. Odonata assemblages structured with segregation are more common going from high to low latitudes, and local species richness have no effect on the pattern. We summarized hypotheses on how biotic interactions or ecological and historical processes can influence the spatial patterns in the checkerboards of assemblages and presented promising ways to help to gain a better mechanistic understanding of the drivers of the Latitudinal Diversity Gradient.

众所周知，纬度会深远地影响生活，其影响可概括为生态规律。向热带地区增加物种多样性是最典型的。几种假设测试了生物相互作用沿纬度的强度模式。负面相互作用（即竞争和掠夺）预计将在产生物种棋盘分布的过程中发生。但是，尚未发现棋盘格与纬度之间的关系。我们使用横跨宽纬度范围（87°）的动物主义数据集（395个物种，分布在386个自然群落中）测试了全球Odonata组合的分离模式。我们使用了共现分析（C得分指数和标准效果大小）作为棋盘格的估计值，然后将偏析的发生与纬度相关联。在我们所分析的群体中，Odonata在区域尺度（即国家尺度）上遵循纬度多样性梯度，而当地的富裕度（即社区尺度）则没有遵循相同的模式。从高纬度到低纬度，带有隔离结构的Odonata组合更为常见，而当地物种的丰富性对格局没有影响。我们总结了有关生物相互作用或生态和历史过程如何影响集合棋盘格中空间格局的假设，并提出了有前途的方式来帮助更好地理解纬度多样性梯度的驱动因素。
