Lo studio ha seguito il ciclo riproduttivo degli uccelli nell'unico frammento del bioma Cerrado situato nel sud del Brasile. L'area è protetta grazie alla creazione di un parco statale, che ne ha impedito la totale conversione in terreni coltivabili. Il Cerrado presenta diverse variazioni nella struttura della vegetazione, che vanno da steppe aperte con presenza di arbusti a una vegetazione densa e di medie dimensioni, riflettendo direttamente la composizione della fauna e della flora. Il tipo di vegetazione scelto per lo studio è stata la porzione più rappresentativa del parco, il Campo Cerrado Alterado, e la sua avifauna e la sua fitofisiognomica sono state studiate in profondità, correlando la riproduzione degli uccelli e la struttura della vegetazione. Questa tesi finale ha permesso di stabilire relazioni non ancora contemplate nel Paese, combinando conoscenze provenienti da aree diverse e fornendo strumenti importanti per la conservazione del sito e delle specie che lo abitano.

Come with me and take a journey through the Cretaceous!The Cretaceous period began 145 million years ago after the end of the Jurassic period and ended 66 million years ago. The Cretaceous period was the third and final period of the Mesozoic era. This was the age of the Dinosaurs. It was in the Cretaceous that saw the rise of Tyrannosaurus rex and Triceratops. In the sky, you would meet Quetzalcoatlus, the largest pterosaur that ever lived, with a wingspan the size of a small plane. In the seas, you would find mosasaurs and plesiosaurs. it was in the Late Cretaceous that saw the first of placental mammals. One of the current theories is that an asteroid impacted the Earth 66 million years ago and ushered in the end of the dinosaurs and with them the Cretaceous period.

The journey for this book started with our Great Grandkids. When Sadie came to us from the breeder, she was 9 weeks old and a bundle of energy. We raised puppy's before, but we were not the main characters in our puppy's lives. Our children were. Because of this technical age we live in, we started making cell phone videos about raising a puppy at our age. Before long, our great grandkids started wanting to see more videos and that started their interest in "Sadie". When we looked at those videos, we noticed Sadie was telling us her story about growing up a "Baker". We decided to put pen to paper and write down what she was telling us. The result is this book.

Il riconoscimento del deterioramento dell'ambiente e del crescente degrado delle componenti degli agro-ecosistemi, come conseguenza di un'agricoltura intensiva con una prospettiva esclusivamente economica, porta inevitabilmente a cambiare questo paradigma di produzione agricola radicato nelle aree agricole del mondo, per uno basato su principi più ecologici che implicano il rispetto dell'ambiente con una tendenza alla sostenibilità nelle nostre terre latinoamericane. A livello internazionale, secondo criteri fondati, sono state avanzate diverse proposte nello scenario rurale per garantire lo sviluppo agricolo, ma nella maggior parte dei casi gli aspetti fitosanitari sono stati affrontati in modo secondario o con un approccio riduzionista - tecnologia di prodotto, protezione delle piante, strategia per controllare il parassita e proteggere la coltura - senza dare molta importanza all'approccio sistemico necessario per gestire i problemi dei parassiti - tecnologia di processo, basi ecologiche, strategia per agire sulle cause con cui i parassiti si manifestano.

Ich habe in dieser Angelegenheit zum ersten Mal festgestellt, dass Krokodile keine Reptilien sind. Krokodile wie Vögel und Säugetiere sind eine eigene Klasse, die von Reptilien abgeleitet wurden. Das Vierkammerherz der Säugetiere, das aus einem reptilienähnlichen Dreikammerherz hervorgegangen ist, besteht aus einer Erweiterung der Scheidewand (der Wand, die die Kammern trennt), dem Verlust des rechten Systembogens und dem Fortbestehen des linken Systembogens. Bei den Vögeln ist der linke Systembogen verloren gegangen und der rechte Systembogen bleibt erhalten. Die Abstammungslinie, die zu den Krokodilen führte, entwickelte auf einem anderen Weg ein Herz mit vier Kammern und behielt beide Systembögen bei. Zoologen unterteilen die Landwirbeltiere in 4 Klassen (Amphibien, Reptilien, Vögel und Säugetiere). Ich bin jedoch zu dem Schluss gekommen, dass die Krokodile eine eigene Klasse bilden. Da Vögel und Säugetiere, die ein vierkammeriges Herz haben, von der Klasse der Reptilien abgeleitet wurden, bilden sie eine eigene Klasse. Krokodil auch, haben vier-Kammer-Herzen und schaffen eine neue Klasse und wurde von der Klasse der Reptilien abgeleitet. Säugetier Vier-Kammer-Herz von einem reptilienartigen Drei-Kammer-Herz ist die Erweiterung der Scheidewand (die Wand, die die Kammern trennt, verloren der rechten systemischen Bogen und der linken systemischen Bogen bleibt).

He encontrado este asunto por primera vez que los cocodrilos no son un reptil. Cocodrilo como las aves y los mamíferos son una clase separada, que se han derivado de los reptiles. Corazón de cuatro cámaras de mamíferos de un reptil como el corazón de tres cámaras es la extensión del tabique (la pared que divide las cámaras, perdido del arco sistémico derecho y el arco sistémico izquierdo persiste). En las aves, pérdida del arco sistémico izquierdo y persiste el arco sistémico derecho. El linaje que conduce a los cocodrilos evolucionó hacia un corazón de cuatro cámaras por una vía diferente, conservando ambos arcos sistémicos. Los zoólogos clasifican a los vertebrados terrestres en 4 clases (anfibios, reptiles, aves y mamíferos). Pero llegué a la conclusión de que su cocodrilo son una clase separada. Como las aves y los mamíferos, con la obtención, el corazón de cuatro cámaras, se han derivado de la clase de los reptiles y crear una clase separada. Cocodrilo también, han hecho los corazones de cuatro cámaras y crear una nueva clase y se ha derivado de la clase de los reptiles. Corazón de cuatro cámaras de mamíferos de un reptil como el corazón de tres cámaras es la extensión del tabique (la pared que divide las cámaras, la pérdida del arco sistémico derecho y el arco sistémico izquierdo persiste).

Die Erkenntnis, dass sich die Umwelt verschlechtert und die Bestandteile der Agrarökosysteme zunehmend geschädigt werden, als Folge einer intensiven Landwirtschaft mit ausschließlich wirtschaftlicher Perspektive, führt unweigerlich zu einem Wechsel dieses Paradigmas der landwirtschaftlichen Produktion, das in den landwirtschaftlichen Gebieten der Welt verwurzelt ist, hin zu einem Paradigma, das auf ökologischeren Grundsätzen basiert, die den Respekt für die Umwelt mit einer Tendenz zur Nachhaltigkeit in unseren lateinamerikanischen Ländern beinhalten. Auf internationaler Ebene wurden auf der Grundlage fundierter Kriterien verschiedene Vorschläge für den ländlichen Raum gemacht, um die landwirtschaftliche Entwicklung zu gewährleisten, doch in den meisten Fällen wurden die phytosanitären Aspekte zweitrangig oder mit einem reduktionistischen Ansatz behandelt - Produkttechnologie, Pflanzenschutz, Strategie zur Schädlingsbekämpfung und zum Schutz der Kulturen -, ohne dem systemischen Ansatz, der für die Bewältigung von Schädlingsproblemen erforderlich ist, große Bedeutung beizumessen - Prozesstechnologie, ökologische Grundlagen, Strategie zur Bekämpfung der Ursachen, durch die sich Schädlinge manifestieren.

O reconhecimento da deterioração do meio ambiente e a crescente degradação dos componentes dos agro-ecossistemas, como conseqüência de uma agricultura intensiva com uma perspetiva apenas econômica, leva inevitavelmente a uma mudança neste paradigma de produção agrícola enraizado nas áreas agrícolas do mundo, por um baseado em princípios mais ecológicos que implicam respeito ao meio ambiente com tendência à sustentabilidade em nossas terras latino-americanas. A nível internacional, de acordo com critérios bem fundamentados, foram apresentadas diferentes propostas no cenário rural para garantir o desenvolvimento agrícola, mas na maioria dos casos os aspectos fitossanitários foram tratados de forma secundária ou com um enfoque reducionista - tecnologia de produtos, proteção de plantas, estratégia para controlar a praga e proteger a cultura - sem dar muita importância ao enfoque sistémico necessário para gerir os problemas de pragas - tecnologia de processos, bases ecológicas, estratégia para atuar sobre as causas pelas quais as pragas se manifestam.

Descobri, pela primeira vez, que os crocodilos não são um réptil. Os crocodilos, tal como as aves e os mamíferos, são uma classe separada, que derivou dos répteis. O coração de quatro câmaras dos mamíferos, a partir de um coração de três câmaras semelhante ao dos répteis, é a extensão do septo (a parede que divide as câmaras, a perda do arco sistémico direito e a persistência do arco sistémico esquerdo). Nas aves, a perda do arco sistémico esquerdo e a persistência do arco sistémico direito. A linhagem que conduziu aos crocodilos evoluiu para um coração de quatro câmaras por um caminho diferente, mantendo ambos os arcos sistémicos. Os zoólogos classificam os vertebrados terrestres em 4 classes (anfíbios, répteis, aves e mamíferos). Mas eu cheguei à conclusão que os crocodilos são uma classe à parte. Como as aves e os mamíferos, com a obtenção de um coração de quatro câmaras, derivaram da classe dos répteis e criaram uma classe separada. Os crocodilos também, com a obtenção de corações com quatro câmaras, criaram uma nova classe e foram derivados da classe dos répteis. O coração de quatro câmaras dos mamíferos, a partir de um coração de três câmaras semelhante ao dos répteis, é o prolongamento do septo (a parede que divide as câmaras, a perda do arco sistémico direito e a persistência do arco sistémico esquerdo).

The recognition of the deterioration of the environment and the increase in the degradation of the components of agroecosystems, as a consequence of intensive agriculture with only an economic perspective, leads inevitably to change this paradigm of agricultural production rooted in the agricultural areas of the world, for another that is based on more ecological principles that imply respect for the environment with a tendency towards sustainability in our Latin American lands. At the international level, according to well-founded criteria, different proposals have been made in the rural scenario to guarantee agricultural development; however, in most cases, phytosanitary aspects have been addressed in a secondary manner or with a reductionist approach - product technology, plant protection, strategy to control the pest and protect the crop - without giving much importance to the systemic approach required to manage pest problems - process technology, ecological bases, strategy to act on the causes by which pests manifest themselves.

J'ai découvert pour la première fois que les crocodiles ne sont pas des reptiles. Les crocodiles, comme les oiseaux et les mammifères, constituent une classe distincte, dérivée des reptiles. Le c¿ur à quatre cavités des mammifères, qui était un c¿ur à trois cavités de type reptile, est le résultat de l'extension du septum (la paroi qui sépare les cavités), de la perte de l'arcade systémique droite et de la persistance de l'arcade systémique gauche. Chez les oiseaux, la perte de l'arc systémique gauche et la persistance de l'arc systémique droit. La lignée menant aux crocodiles a évolué vers un c¿ur à quatre chambres selon une voie différente, en conservant les deux arcs systémiques. Les zoologistes classent les vertébrés terrestres en 4 classes (amphibiens, reptiles, oiseaux et mammifères). Mais je suis arrivé à la conclusion que leurs crocodiles constituent une classe à part. Comme les oiseaux et les mammifères, avec l'obtention d'un c¿ur à quatre cavités, ont été dérivés de la classe des reptiles et créent une classe séparée. Les crocodiles aussi, en obtenant des c¿urs à quatre chambres, ont créé une nouvelle classe et ont été dérivés de la classe des reptiles. Le c¿ur à quatre cavités des mammifères, à partir d'un c¿ur à trois cavités semblable à celui des reptiles, est le prolongement du septum (la paroi qui sépare les cavités, la perte de l'arc systémique droit et la persistance de l'arc systémique gauche).

Ho scoperto per la prima volta che i coccodrilli non sono rettili. I coccodrilli, come gli uccelli e i mammiferi, sono una classe separata, derivata dai rettili. Il cuore quadricamerale dei mammiferi è stato trasformato in un cuore tricamerale simile a quello dei rettili grazie all'estensione del setto (la parete che divide le camere, la perdita dell'arco sistemico destro e la persistenza dell'arco sistemico sinistro). Negli uccelli, la perdita dell'arco sistemico sinistro e la persistenza dell'arco sistemico destro. La stirpe che porta ai coccodrilli ha evoluto un cuore a quattro camere lungo un percorso diverso, mantenendo entrambi gli archi sistemici. Gli zoologi classificano i vertebrati terrestri in 4 classi (anfibi, rettili, uccelli e mammiferi). Ma sono giunto alla conclusione che i loro coccodrilli sono una classe a parte. Poiché gli uccelli e i mammiferi, ottenendo un cuore a quattro camere, sono derivati dalla classe dei rettili e creano una classe separata. Anche il coccodrillo, con l'ottenimento di cuori a quattro camere, ha creato una nuova classe ed è derivato dalla classe dei rettili. Il cuore quadricamerale dei mammiferi, derivato dal cuore tricamerale dei rettili, è costituito dall'estensione del setto (la parete che divide le camere, dalla perdita dell'arco sistemico destro e dalla persistenza dell'arco sistemico sinistro).

Wussten Sie, dass Kamerun seinen Namen einem Krebs verdankt und Hummer in Amerika einst an Nutztiere verfüttert wurden? Dass Jean-Paul Sartre viele Jahre lang von schrecklichen Langusten träumte? Kennen Sie die Erzählungen, laut denen japanische Samuraikrieger als auffällig gemusterte Krabben wiedergeboren wurden?Nein? Dann wird es dringend Zeit, dass Sie sich zusammen mit Heinz-Dieter Franke auf eine Reise in die kuriose Welt der Krebse begeben. In seiner reich bebilderten Kulturgeschichte erzählt der Autor unterhaltsam und prägnant, wie die Krustentiere ihren Weg an den Sternenhimmel, in die Küchen der Ärmsten und der Reichsten sowie in internationale Sprichwörter und Legenden fanden. Und so viel sei verraten: Rückwärts ging es dabei nicht.

Wie Intelligenz bei einem Tier nachweisen, das nur wenige Wochen lebt?Lars Chittka erzählt uns unterhaltsam von den Wundern natürlicher Intelligenz selbst bei winzigen Tieren. Bienen entwickeln im Schwarm faszinierende Fähigkeiten, sind aber auch als Individuen verblüffend intelligent. Neue bahnbrechende Forschungen zeigen, dass sie denken und fühlen, dass sie Persönlichkeit, wenn nicht gar Bewusstsein besitzen. Bienen zählen, erkennen menschliche Gesichter und nutzen Werkzeuge, sie lösen Probleme durch Nachdenken und reagieren individuell auf äußere Reize. Und das alles mit völlig anderen Sinnesorganen: Dank ihres kompakten Nervensystems navigieren sie präzise und speichern Informationen, ihre Antennen sind multifunktional wie Schweizer Messer.Das neue Standardwerk über die Biene
