Simulated effects of site salinity and inundation on long-term growth trajectory and carbon sequestration in monospecific $Rhizophora\; mucronata$ plantation in the Philippines [PDF]

arXiv, 2014
A mathematical model of coastal forest growth is proposed to describe and test the effects of salinity and inundation in the long-term growth performance and carbon sequestration of monospecific mangrove ($Rhizophora\; mucronata$) plantation in the Philippines.

Past research and future directions in understanding how birds use their sense of smell

Ibis, EarlyView.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

Comparing the migration behavior and survival of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) smolts

Journal of Fish Biology, EarlyView.
Abstract Many organisms rely on migrations between habitats to maximize lifetime fitness, but these migrations can be risky due to a suite of factors. In anadromous salmonids, the smolt migration from fresh water to sea is a critical life stage, during which smolts can experience high mortality from multiple sources.

Challenges in downstream dam passage and the effect of dam removal on Atlantic salmon (Salmo salar) smolt migrations

Journal of Fish Biology, EarlyView.
Abstract Migration is critical for life‐cycle completion in diadromous fish species. River connectivity is vital in facilitating these large‐scale movement events, but the extent of present‐day river fragmentation can interfere with these migrations. Fish passage solutions (FPSs) are commonly implemented with the aim of improving river connectivity. In

Validation of a new acoustic telemetry transmitter for the study of predation events in small fishes

Journal of Fish Biology, EarlyView.
Abstract Acoustic telemetry has emerged as an important tool for studying the movement and behavior of aquatic animals. Predation‐sensing acoustic transmitters combine the functions of typical acoustic transmitters with the added ability to identify the predation of tagged animals.

Ecological aspects of nematode parasites of introduced salmonids from Valdivia river basin, Chile

Memorias do Instituto Oswaldo Cruz, 1991
Between 1986 and 1987 fishes distributed among the following species introduced in Chile, and from different sectors of the Valdivia river basin (39º30' - 40º00', 73º30' - 71º45'W), were examined: 348 Salmo trutta, 242 Salmo gairdneri, 24 Cyprinus carpio

In situ infestation of sea trout Salmo trutta with salmon louse Lepeophtheirus salmonis reveals parasite‐induced behavioral modifications

Journal of Fish Biology, EarlyView.
Abstract In areas with high densities of salmon farming, spillover of the ectoparasitic salmon louse Lepeophtheirus salmonis poses a major threat to wild anadromous salmonids. By combining experimentally salmon louse infestation (mean ± standard deviation = 0.25 ± 0.25 lice g−1 fish) with acoustic telemetry, we studied the behavior of wild first‐time ...

Fast and cost‐efficient species identification of Atlantic salmon (Salmo salar L.), brown trout (Salmo trutta), and their hybrids using a single SNP marker

Journal of Fish Biology, EarlyView.
Abstract A workflow for developing a cost‐ and time‐efficient, single nucleotide polymorphism (SNP)‐based assay for species and hybrid identification is described. In a reference set (n = 46), the developed assay identified individuals of two closely related species, the Atlantic salmon (Salmo salar L., n = 23) and brown trout (Salmo trutta, n = 23 ...
