“…Our findings corroborate evidence of demographic expansion in amphidromous species elsewhere in the Indo‐Pacific (Crandall et al ., ; Hoareau et al ., ; Chabarria et al ., ). Prior studies have found genetic signatures indicating that estimated times of the most recent population expansions are associated with Pleistocene sea level fluctuations (Crandall et al ., ; Hoareau et al ., ; Lord et al ., ; Chabarria et al ., ). However, we found that the magnitude of expansions was strikingly variable, implying that demographic histories may vary independently across a species’ range and among codistributed species (Hoareau et al ., ; Lord et al ., ).…”

It is widely accepted that insular terrestrial biodiversity progresses with island age because colonization and diversification proceed over time. Here, we assessed whether this principle extends to oceanic island streams. We examined rangewide mtDNA sequence variation in four stream-dwelling species across the Hawaiian archipelago to characterize the relationship between colonization and demographic expansion, and to determine whether either factor reflects island age. We found that colonization and demographic expansion are not related and that neither corresponds to island age. The snail Neritina granosa exhibited the oldest colonization time (~2.713 mya) and time since demographic expansion (~282 kya), likely reflecting a preference for lotic habitats most prevalent on young islands. Conversely, gobioid fishes (Awaous stamineus, Eleotris sandwicensis and Sicyopterus stimpsoni) colonized the archipelago only ~0.411-0.935 mya, suggesting ecological opportunities for colonization in this group were temporally constrained. These findings indicate that stream communities form across colonization windows, underscoring the importance of ecological opportunities in shaping island freshwater diversity.

In this study, we use eight microsatellite loci and a mitochondrial locus to investigate the population structure of the amphidromous goby species Stiphodon rutilaureus in the New Georgia Group, Solomon Islands. In total, 206 specimens were collected between June 2010 and August of 2012 on three different trips. The AMOVA results from both types of loci reveal that >95% of variation is contained within populations. Pairwise comparisons reveal non-significant differences between three different regions for the mitochondrial analysis but a significant difference between the west and central regions for the microsatellites. The findings in this study concur with results from previous studies, indicating low or no population structure among populations of amphidromous sicydiine goby species on different islands within an archipelago. This study can provide suggestions for management and conservation of fragile aquatic species.
