Trucchi, consigli emolto altro per tenere al meglio la pianta carnivora per eccellenza. Vedremo quali sono le nozioni base da sapere e impareremo in modo semplice anche le cose piu complicate nel gestire la dionaea muscipula, chiamata anche venere acchiappamosche.

Necesitamos saber quiénes somos y de dónde venimos para entender las luces y sombras de nuestro presente y, sobre todo, para aproximarnos a las teorías y conjeturas sobre un futuro incierto, marcado por una tecnologia cuyo progreso exponencial escapa a menudo a nuestra completa comprension y al particular ritmo de los cambios biologicos. Dioses y mendigos nos propone un fascinante viaje para revisitar nuestros origenes como especie, penetrar en los enigmas del cerebro y la genetica y redescubrir el papel central de la cultura en la historia de la Humanidad. Somos una forma de vida muy particular, con una enorme inteligencia y, al mismo tiempo, con una mayuscula fragilidad. La primera, impulsada por los cambios genomicos y la seleccion natural, nos ha permitido expandirnos y someter a nuestros designios ecosistemas y especies. Sin embargo, esta misma preeminencia nos aproxima al colapso en forma de emergencia climatica, agotamiento de recursos y la consecuente extincion o transhumanismo. Para conjurar esta incertidumbre, Jose Maria Bermudez de Castro plantea renovar nuestra apuesta por la ciencia y el conocimiento, consciente de que la evolucion sigue en marcha. Conocer nuestra naturaleza es una imperiosa necesidad, mas aun cuando nos hemos alejado demasiado de la realidad a la que pertenecemos y olvidado que formamos parte de la biodiversidad y estamos sometidos a sus leyes.

The Direct Seeding System (DSS), also known as Direct Planting System, is a technique that enables several environmental benefits, as it increases the levels of organic matter and the biological activity of the soil, reduces soil temperature fluctuations, reduces laminar erosion, as well as carrying of fertilizers and pesticides for water sources, reduces the population density of weeds and allows greater conservation of soil moisture, being, therefore, considered a sustainable production system. It is noteworthy that this soil water conservation is generally one of the biggest advantages of the DSS. This is because the crop residues remain on the soil surface, where they act as a barrier to water loss through evaporation, provide an increase in surface roughness, reducing the speed and volume of surface runoff, favoring infiltration and increasing water available for plants.

O papa da biodiversidade traça um abrangente e apaixonado painel da alarmante situaço da ecologia no mundo de hoje, propondo soluçes.Reconhecido no mundo todo como o papa da biodiversidade, Wilson analisa aqui os processos adaptativos responsaveis pela criaço de novas especies e descreve os cataclismos que interromperam a evoluço e empobreceram a diversidade nos ultimos seiscentos milhes de anos. Os cinco primeiros desastres ecologicos (tais como meteoritos e mudanças climaticas) custaram a evoluço entre dez e cem milhes de anos de reparaço. Ja o sexto grande espasmo de extinço na Terra, desta vez inteiramente causado pelo homem, pode no ter conserto.Wilson aponta fortes indicios de que o planeta caminha para um grave e talvez irreversivel processo de degradaço ambiental: declinio da populaço de passaros nos Estados Unidos, extinço de especies de peixes de agua doce na Africa e na Asia, drastica reduço de flora e fauna nas regies tropicais desmatadas. As saidas que o autor prope so complexas, a altura do problema, mas factiveis, e passam por conciliar produço, lucro e proteço ambiental. Desafiadoras, elas permitem que a consciencia ecologica e as praticas sociais alcancem novo patamar, tanto nos estudos quanto nas atitudes individuais e politicas de preservaço do meio ambiente.
