Landscape patterns in top-down control of decomposition: omnivory disrupts a tropical detrital-based trophic cascade

ECOLOGY, 100(7).

MeSH headings : Animals; Biomass; Ecosystem; Plant Leaves; Poecilia; Predatory Behavior; Trinidad and Tobago
TL;DR: Top-down effects of three macroconsumer species on detrital processing in headwater streams draining Trinidad's northern mountains are isolated, revealing that omnivory can result in significant indirect effects on a key ecosystem process and suggesting that resource control in tropical systems may be even more complex than previously envisioned.

Migratory gauntlets on oceanic islands: Watershed disturbance increases the cost of amphidromy

Ecology of Freshwater Fish, 28(3), 446–458.

By: E. Hain n, K. Moody*, B. Lamphere*, S. Nelson n, P. McIntyre*, J. Gilliam n, M. Blum*

author keywords: biological invasions; diadromy; Gobiidae; Hawai'i; land use; Poeciliidae
TL;DR: Densities of native Hawaiian amphidromous fishes are equally or more sensitive to conditions along migratory pathways relative to conditions in primary residential habitats, suggesting alleviating pressures by removing invasive species and restoring habitat along dispersal pathways could be effective approaches to increasing densities.

Overcoming urban stream syndrome: Trophic flexibility confers resilience in a Hawaiian stream fish

FRESHWATER BIOLOGY, 63(5), 492–502.

By: P. Lisi*, E. Childress*, R. Gagne*, E. Hain n, B. Lamphere*, R. Walter*, J. Hogan*, J. Gilliam n, M. Blum*, P. McIntyre*

author keywords: amphidromy; aquatic invasive species; goby; omnivory; urbanisation
TL;DR: Flexibility in diet, life history and habitat use of this native goby appear to buffer it against the effects of urbanisation compared to most other amphidromous fishes in Hawaiian streams, indicating that dietary flexibility buffers this species against environmental degradation.

Invasion of the Hawaiian Islands by a parasite infecting imperiled stream fishes

ECOGRAPHY, 41(3), 528–539.

TL;DR: These findings parallel historical records of non-native poeciliid introductions and suggest that remediating invasion hotspots could reduce the risk of infection in native stream fishes, which illustrates how inferences on parasite co-introductions can improve conservation efforts by guiding responses to emerging infectious disease in species of concern.

Local Adaptation in Trinidadian Guppies Alters Stream Ecosystem Structure at Landscape Scales despite High Environmental Variability

Simon, T. N., Bassar, R. D., Binderup, A. J., Flecker, A. S., Freeman, M. C., Gilliam, J. F., … Pringle, C. M. (2017, September). COPEIA, Vol. 105, pp. 504–513.

By: T. Simon, R. Bassar, A. Binderup, A. Flecker, M. Freeman, J. Gilliam*, M. Marshall, S. Thomas ...

TL;DR: The results demonstrate that local adaptation can produce phenotypes with significantly different effects in natural ecosystems at a landscape scale, within a tropical watershed, despite high variability in abiotic factors: five of the seven physical and chemical parameters measured across the eight study streams varied by more than one order of magnitude.

Consequences of alternative dispersal strategies in a putatively amphidromous fish

ECOLOGY, 95(9), 2397–2408.

author keywords: amphidromy; Awaous stamineus; complex life cycle; connectivity; cost-benefit; dispersal strategy; fitness; growth; Hawaii; larvae; metapopulation; stream fish
TL;DR: Investigating variability in dispersal histories of a freshwater fish, Awaous stamineus, across the species' entire geographic range in the Hawaiian archipelago finds that individuals with marine dispersal have shorter larval durations and faster larval growth, and their growth advantage over purely freshwater counterparts continues to some degree into adult life.

author keywords: boldness; movement; dispersal; leptokurtic; exploration; Rivulus
