Introduction The abundant-center hypothesis (ACH; Brown 1984) is a foundational macroecology theory. The ACH predicts that the abundance of a species is greatest in the center of its geographic range where habitat is the most suitable and decreases towards the range edges due to decreased fitness associated with declining habitat suitability (Fig. 1A, Brown, 1984, Brown et al. 1995).

These ‘invasion hypotheses’ are commonly conceptualised as the spatiotemporal interplay between three key mechanisms.

AbstractTransitions between dry and wet hydrologic states are the defining characteristic of non-perennial rivers and streams, which constitute the majority of the global river network. Although past work has focused on stream drying characteristics, there has been less focus on how hydrology, ecology and biogeochemistry respond and interact during stream wetting.

INTRODUCTION Rapid expansion of internet connectivity and mobile technology has led to a fundamental transformation of the retail landscape. Sales of undomesticated ornamental or pet species (henceforth, pet trade) have similarly expanded beyond “brick-and-mortar” retail stores to include a rapidly growing number of online retailers and marketplaces (Liu et al., 2021; Marshall et al., 2020; Siriwat & Nijman, 2020).
