Can backcalculation models unravel complex larval growth histories in a tropical freshwater fish?NARA Subscribed
This experimental study compared the precision and accuracy of the biological intercept ( BI ), modified fry ( MF ) and time‐varying growth ( TVG ) backcalculation models in estimating the early growth of the tropical freshwater purple‐spotted gudgeon Mogurnda adspersa . Larvae were reared up to 41 days post hatching under two temperatures and four different feeding regimes. Food and temperature treatments induced complex grow...
Climate‐associated population declines reverse recovery and threaten future of an iconic high‐elevation plantNARA Subscribed
Although climate change is predicted to place mountain‐top and other narrowly endemic species at severe risk of extinction, the ecological processes involved in such extinctions are still poorly resolved. In addition, much of this biodiversity loss will likely go unobserved, and therefore largely unappreciated. The H aleakalā silversword is restricted to a single volcano summit in H awai‘i, but is a highly charismatic giant ro...
Using sprint swimming performance to predict upstream passage of the endangered Macquarie perch in a highly regulated riverNARA Subscribed
Barriers to migration are a major threat to freshwater fish populations. A novel measurement of swimming speed performance and an analytical model were used to calculate the probability that endangered Macquarie perch, Macquaria australasica Cuvier, can swim through instream structures. Over the range of river discharges (2.7–166 ML day −1 ) and temperatures (10–22 °C) examined, M. australasica could successfully pass through...
Over the last two and half decades, strong evidence showed that the terrestrial ecosystems are acting as a net sink for atmospheric carbon. However the spatial and temporal patterns of variation in the sink are not well known. In this study, we examined latitudinal patterns of interannual variability (IAV) in net ecosystem exchange (NEE) of CO 2 based on 163 site‐years of eddy covariance data, from 39 northern‐hemisphere resea...
Mixed‐stock analysis reveals the migrations of juvenile hawksbill turtles ( Eretmochelys imbricata ) in the Caribbean SeaNARA Subscribed
Hawksbill turtles ( Eretmochelys imbricata ) migrate between nesting beaches and feeding habitats that are often associated with tropical reefs, but it is uncertain which nesting colonies supply which feeding habitats. To address this gap in hawksbill biology, we compile previously published and new mitochondrial DNA (mtDNA) haplotype data for 10 nesting colonies ( N = 347) in the western Atlantic and compare these profiles to...
The prevalence of escaped farmed Atlantic salmon, Salmo salar L., in the River Ewe, western Scotland, was assessed. After the establishment of smolt cages in the catchment and marine cages near the river mouth during 1986–1987, approximately 425 000 parr and smolts, and 122 000 growers have escaped. Between 1987 and 2001, farmed salmon occurred in the rod fishery in 13 of the 15 years, contributing at least 5.8% of the total c...
