The Arctic charr is a cold-water fish in the family Salmonidae. Its distribution is circumpolar, where it supports important commercial and indigenous fisheries. Many freshwater lakes and streams are inhabited by different forms or ‘morphs’ of the species. These forms can differ remarkably in size, body shape and color, as well as behaviors such as feeding or migration. It is currently uncertain whether different morphs throughout the species geographic range will respond similarly to climate change. To help address this knowledge gap, we’ve recently published a study characterizing the genetic diversity and population structure of Arctic charr morphs from two lakes in Svalbard, Norway. These genetic results provide insight as to how frequently the morphs breed together and if they represent distinct populations. We can then use this information to predict how different morphs will respond to climate change and ultimately incorporate this information into fisheries management and conservation decisions.

Living My Values
I have mentioned before that some of my ‘sustainable’ values actually can be viewed as quite negative. I hoard, sorry collect, thinking one day I will fix it, one day it will show me its purpose, one day I will find time to make something with my collection. But a term I learnt from a colleague was around product hibernation, the realisation that we all have products in our homes collecting dust. Even old products that no longer work like old mobiles, laptops and cameras. Products which could be recycled for parts. But the product designer in me likes the antique/retro mini disc player, a technology which never really caught on but is a snapshot from design history. I visited a #Landfill site years ago and the images I saw and the scale of it all still haunts me. Now my local recycling centre does accept broken electrical items. I am better at discarding broken and irreparable items knowing they won’t be buried in our soil. That’s why the materials I select for our growing kits are so important to me.
I would love to have a wonderfully productive edible garden. As a #permaculture gardener, I am often stuck in the observation and planning phase, with too many ideas to know what I want to do. I always have high hopes for how much I can grow in my garden, but like many others, I struggle with time when working so much. I need to be more realistic and follow the rules of The Crop Club kits which are designed to be small, compact and manageable.
My core value though is around supporting and working with others. This value forms a part of my daily life and keeps me motivated. Along with this is the desire to make our environment better, reduce negative impacts and create more biodiversity. These big issues and challenges couldn’t be tackled easily alone.
The red-footed tortoise is a medium-sized tortoises generally average 30 cm (12 in) as adults, but can reach over 40 cm (16 in). They are popularly kept as pets, and over-collection has caused them to be vulnerable to extinction. 📷 You can photograph it in our expedition to Pantanal 2019! 📷

HEALTHY SEAGRASS ➡️ HEALTHY CORAL REEFS
Seagrass beds create a highly suitable environment for almost any creature you can find on a reef, including humans. Competition and predation are much lower here than on coral reefs, making seagrass beds the perfect nursery for many reef species. Some species spend the majority of their lives in seagrass beds. Scientists estimate that the shelter and food provided by a single acre of healthy seagrass can sustain 40,000 fish and tens of millions of small invertebrates. Unfortunately, seagrass beds are at high risk from dredging, runoff pollutants, nutrification and overfishing and they are disappearing at a rate of 1.5 percent annually.
How you can help: Avoid driving your boat across seagrass on the way to your dive site. If impossible to avoid, lift your outboard engine in shallow water. Don’t anchor in seagrass. Properly store and dispose fuel and oil. Fish sustainably (within bag and size limits). Snorkel carefully over seagrass beds instead of wading through them on foot. Join a local conservation group! People are replanting seagrass right now.

It's really hard to capture the magnificence and sheer numbers of a starling murmuration in a still photo. Everything that makes them so incredible is rooted in their movements; the fluidity of thousands of starlings flowing in unison and painting the sky with their shapes. Last year I was lucky enough to watch this spectacle at a nearby nature reserve, on a gorgeous & still January evening. The wintry light at dusk made the perfect canvas for the starlings, sweeping in front of the hide we sat in, gawping at their beauty 😍 #winterwatch@bbcspringwatch
Take some time to look for green areas in your city, you never know what you'll find! In a park just on the outside of Bristol we had a fantastic time watching this male kingfisher who lives on a tiny river. Bathing and fishing a lot, this bird shoes us again how busy the lives of some animals are! We also saw a sparrowhawk sitting on one of the kingfishers perches, could this spell out worry for this little guy?
No tengo a la mano mi libro de identificacion de aves del Perú, en cuanto lo tenga pondre el nombre de esta avecita que vi la semana pasada en los bosques secos de Chiquiac en #Huancavelica . Este angosto valle está conformado por el bosque seco interandino del rio Mantaro.
Está por demas decir que es uno de mis ecosistemas favoritos, pues en el hice mi investigacion de tesis universitario y de maestría, aunque este ultimo fue hecho en los #bosquessecos de #Piura .
Aqui hay venados, perdices, gato andino (quizas gato del pajonal), muchas mas mamiferos, muchas aves, y la flora, variedad de cactus, un familiar silvestre de la papaya y mi lindo arbol Eriotheca, el mas grande de estos bosques y que da una sombra aliviadora en medio de tan altas temperaturas que se registran en estos valles.
Aqui lamentablemente tambien se da la caza de venados 😢 y la agricultura esta avanzando destruyendo su habitat. Espero que pronto este lugar se convierta en una area protegida.
Cuidemos lo que tenemos.
The double-crested cormorant is one of two cormorant species in Nova-Scotia. It can typically be distinguished from the Great cromorant from its orange throat patch and smaller size.
The cormorant feeds on fish and when taking off it must engage in vigorous flapping to gain elevation, as altutide is typically lost in the intial moments of flight. If you look closely, you will often see them dragging their feet in the water before gaining height. .

If you're alarmed by the global decline in insect and arachnid populations, here's some good news. Five new spider species have been discovered in our Hills of Gold conservation area, testifying to its incredible biodiversity. A new native pollinator was found in Burnett Woods Nature Preserve. Who knows what critical species might yet be uncovered in the 5000+ acres we currently protect?
La #nutria gigante, #enpeligrodeextincion, habita principalmente el río #Amazonas y en el Gran #Pantanal. En las últimas décadas su distribución se ha reducido considerablemente y se ha tornado discontinua a raíz de la caza para aprovechar su piel. Se estiman menos de 5000 individuos en su medio natural. La DEGRADACIÓN Y PÉRDIDA DEL HÁBITAT se convirtió en la principal amenaza tras la suspensión de la caza.
La nutria gigante tiene hábitos diurnos; los adultos miden entre 1,50 y 1,80 m y pesan entre 22 y 45 kg. A diferencia de los otros mustélidos es una especie social, con grupos familiares que suelen tener de tres a ocho miembros. Se alimenta principalmente de pescado, en particular characiformes (como las pirañas) y bagres; también puede comer cangrejos. No tiene depredadores naturales de importancia (la amenaza más grande fueron y siguen siendo los humanos), aunque debe competir por recursos alimenticios con otras especies

A new report from Panthera and other NGOs that surveyed more than 330 park rangers in #CentralAmerica found that almost 80% have encountered a life-threatening situation while on the job. Many are missing even the most basic training needed to navigate the difficulties of their profession. The report identifies the need of governments to give more support to rangers and the programs they implement. “If we really want these protected areas to work, if we want the wildlife corridors to work, we really need to secure the right conditions for the park rangers,” Panthera’s Roberto Salom told @Mongabay. A surprising finding? Despite often “subhuman” conditions, the majority of these rangers expressed their passion for protecting #biodiversity and their desire to pass that love on to the next generation.
