When a range-shifting species colonizes an ecosystem it has not previously
inhabited, it may experience suboptimal conditions that challenge its
continued persistence and expansion. Some impacts may be partially
mitigated by artificial habitat analogues: artificial habitats that more
closely resemble a species’ historic ecosystem than the surrounding
habitat. If conditions provided by such habitats increase reproductive
success, they could be vital to the expansion and persistence of
range-shifting species. We investigated the reproduction of the mangrove
tree crab Aratus pisonii in its historic mangrove habitat, the suboptimal
colonized salt marsh ecosystem, and on docks within the marsh, an
artificial mangrove analogue. Crabs were assessed for offspring production
and quality, as well as measures of maternal investment and egg quality.
Aratus pisonii found on docks produced more eggs, more eggs per unit
energy investment, and higher quality larvae than conspecifics in the
surrounding salt marsh. Yet, crabs in the mangrove produced the highest
quality larvae. Egg lipids suggest these different reproductive outcomes
result from disparities in the quality of diet-driven maternal
investments, particularly key fatty acids. This study suggests habitat
analogues may increase the reproductive fitness of range-shifting species
allowing more rapid expansion into, and better persistence in, colonized
ecosystems.
