Depth distribution of the amoebic gill disease agent, Neoparamoeba perurans, in salmon sea-cages

Aquaculture Environment Interactions, 2015
Identifying where and when parasites occur in farming environments is vital to understand transmission dynamics and develop preventative measures that reduce host-parasite encounters.

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

Nordic Journal of Botany, EarlyView.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

Oikos, EarlyView.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

Oxidative Stress Response of Liver Cell Culture in Atlantic Salmon Challenged Under Two Antibiotics: Oxytetracycline and Florfenicol

Toxics
Aquaculture is currently the fastest-growing sector in animal production, with an average annual growth rate of 7.5% since 1970. In Chile, the industry is largely driven by salmonid farming, with Salmo salar (Atlantic salmon) accounting for over 65% of ...

Engaging the public in plant science: Communication facilitators and barriers of scaling up a citizen science campaign

People and Nature, EarlyView.
Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Growth and welfare of submerged Atlantic salmon under continuous lighting

Aquaculture Environment Interactions, 2018
Although surface-based cages dominate the marine finfish aquaculture industry, production issues that arise at the surface such as poor environmental conditions and the presence of parasites has spurred interest in submerging cages.

Shifting the paradigm: An Indigenous knowledge‐based stewardship plan to replenish boreal caribou in Athabasca Chipewyan and Mikisew Cree First Nations' homelands

People and Nature, EarlyView.
Abstract Indigenous Peoples in northern Alberta, including Dené and Cree of the Athabasca Chipewyan and Mikisew Cree First Nations (ACFN and MCFN), have been using Indigenous laws and stewardship principles to care for their homelands for thousands of years. Since ACFN and MCFN signed Treaty 8 with Canada in 1899, Alberta's land management policies and

The Salmon Louse Lepeophtheirus salmonis (Copepoda: Caligidae) life cycle has only two Chalimus stages.

PLoS ONE, 2013
Each year the salmon louse (Lepeophtheirussalmonis Krøyer, 1838) causes multi-million dollar commercial losses to the salmon farming industry world-wide, and strict lice control regimes have been put in place to reduce the release of salmon louse larvae ...
