Spring is coming soon!

Hello friends!

Spring is just around the corner and I can’t wait for it, because this winter was too cold for me and longer than I expected. But the sun is up, snow is melting and flowers are almost in bloom. With all this fresh air I have some new ideas for my blog. I want to change it and make it more personal and closer to my heart. So, I have prepared for you more photography, stories and different topics that I love, all `inspired by nature`, but in a friendlier style, less scientific. Also, I will develop some new projects later on this year. Stay close to see what`s new.

I wish you all a beautiful spring!

News: Africa`s baobab trees are dying

The baobab is the iconic tree from Africa. It belongs to Adansonia genus. These trees are found in Madagascar, mainland Africa and Australia. They are very popular becouse they can live longer than 2000 years. For exemple the Panke baobab in Zimbabwe was 2450 years old when it died in 2011.

Unfortunatly the oldest and largest baobab trees in Africa are dying. In a study intended to investigate the age, structure and longevity of Africa`s largest and potentially oldest baobabs, researchers were surprised to find that several of trees died during the study period (2005-2017). But the sad news are that the researchers found no signs of an epidemic or disease, the only answer they have is that the climate change could be the reason for their death.

Noi descoperiri in Madagascar

Insula Madagascar este un paradis al biodiversitatii. Cele mai fascinante, unice si colorate animale traiesc pe aceasta insula, iar 90% dintre ele nu traiesc in nici un alt loc din lume. Printre aceste vietati se numara si cameleonii. Nu mai putin de 80 de specii de cameleoni se afla in Madagascar, iar anul acesta au fost descoperite inca 3 specii noi.

David Protzel, de la Universitatea Ludwig Maximilian din Munich, Germania, impreuna cu echipa sa, au identificat 3 specii noi de cameleoni prin examinarea organelor genitale si analizarea unor gene a sute de indivizi de pe insula. Dupa toate analizele amanuntite au iesit la iveala 3 indivizi diferiti fata de celelalte specii deja cunoscute. Toti sunt mici, avand aproximativ 10 cm lungime si au nasul lung cu mici apendici care cresc pe el dandu-i un aspect bulbos. Se spune despre acesti cameleoni ca ar avea nas asemanator cu marioneta Pinocchio.

Ceea ce este cu adevarat special si spectaculos la aceste animalute este culoarea. Nu degeaba sunt supranumiti cameleoni „curcubeu” deoarece pielea lor este foarte colorata in special cu nuante de galben, rosu si violet. Cameleonii curcubeu nu sunt usor de gasit, ei traiesc undeva in nordul insulei Madagascar, iar numarul indivizilor este foarte scazut.

NEW! Calumma uetzi

Cele 3 specii noi descrise fac parte din genul Calumma. Acest gen de cameleoni este endemic pentru Madagascar si de asemenea sunt specii restranse, ceea ce denota ca nu le vom intalnii in alta zona din lume. Calluma uetzi, a fost denumita dupa Peter Uetz, un cercetator cu o baza de date incredibila formata din specii de reptile. Masculii din aceasta specie pot fi recunoscuti dupa culorile pielii si anume ocru, turcoaz, rosu aprins si mov. Calumma lefona, este deosebita de ceilalti cameleoni datorita rostrului (nasul) in forma de bulb. Denumirea sa provine de la cuvantul „lefona” care in limba malgasa inseamna „sulita, spada”. Ultima specie descoperita este Calumma juliae, fiind denumita dupa Julia Forster, care a ajutat la colectarea indivizilor. Aceste specii au fost gasite pana acum intr-o arie de aproximativ 0,15 km patrati de padure, iar echipa de cercetatori a cerut protejarea imediata a zonei.

Sea turtles eat with their flippers

The sea turtle

Kingdom: Animalia
Phylum: Chordata
Class: Reptilia
Order: Testudines
Family: Cheloniidae
Genus: Chelonya
Species: Chelonya mydas

animal-aquarium-aquatic-668867The flippers of sea turtles are superbly adapted for swimming and according to many scientist this is the only function they have. But recently Jessica Fujii at the Monterey Bay Aquarium in California has compiled evidence that turtles use their flippers to handle and eat their prey. Jessica and her team published online videos with three species of sea turtles using their flippers to hold jellyfish and other creatures while consuming the edible parts. sea-life-sea-turtle-turtle-38452

News: Chinese government is investing a lot of money to creat a huge conservation area for giant pandas. The park cover 27.134 km across Sichuan, Shaanxi and Gansu provinces. Scihuan is the habitat for 80% of the world`s pandas. The forestry departament, the Bank of China and other parties agreed to invest 1.58 billion US$ in the park over the next 5 years. Conservation efforts have helped boost the population of wild pandas to about 1.900 individuals.

News: Warming puts penguins at risk-Incalzirea globala afecteaza habitatul pinguinilor

[EN] Climate change could force millions of king penguins to seek new breeding grounds by the end of the century. King penguins (Aptenodytes patagonicus) breed on islands throughout the Southern Ocean and feed where the ocean`s warm and cold waters meet. Due to climate change, 70% of king penguins, roughly 1.1 milion breeding pairs, will be forced to find new breeding grounds, or else disappear, by 2100. As climate change moves the penguin`s feeding grounds southward, relocating birds will have to hop from island to island to follow their food. Low genetic diversity and breeding rates are likely to limit the penguin`s ability to adapt to changing conditions.animals-cold-cute-52509[RO] Schimbarile climatice din ultima vreme se pot observa la nivelul intregii planete. Fiecare individ este afectat intr-o oarecare masura de aceste schimbari. In articolul de azi discutam despre schimbarile suferite de pinguinii din zonele reci ale planetei. Din pacate incalzirea globala nu a ocolit aceste zone, din contra, aici se observa cele mai radicale schimbari, iar statisticile nu aduc vesti bune pentru viitor.animals-beaks-birds-53970Din cauza acestor schimbari, in special incalzirea temperaturilor si topirea ghetarilor, ar putea forta pinguinii imperiali sa migreze in cautarea unor noi terenuri pentru reproducere. Pinguinul imperial (Aptenodytes patagonicus) traieste in insulele din Antarctica si se hraneste la granita dintre oceanul cald si oceanul rece.animal-beaks-bird-209096Datorita schimbarilor de clima, continentul inghetat sufera modificari drastice care forteaza cel putin 70% din pinguini (1.1 milioane de perechi) sa-si mute habitatul si sa gaseasca alte zone, mai sigure, pentru imperechere. Daca pinguinii nu gasesc zone noi, mai reci si nu reusesc sa migreze la timp, acestia sunt in pericol de disparitie. Pana in 2100 nu va mai exista nici un exemplar. Un alt factor decisiv pentru aceasta specie este bagajul genetic foarte slab care nu ajuta pinguinii imperiali sa se acomodeze rapid la schimbarile de mediu. In concluzie, incalzirea globala este un pericol real pentru sute de specii, din pacate chiar si cele din zone mai putin populate si foarte reci.animal-antarctic-bird-270196Source: Climate-driven range shifts of the king penguin in a fragmented ecosystem, Nature climate change, Christofari et. al., 2018
