Planternes biologi

Vidste du, at træer kan påvirke jordens rotation? Eller at ulve kan ændre, hvordan floder løber? Eller at regnorme kontrollerer vildsvinepopulationen? Naturen består af et net af komplicerede forbindelser, og langt de fleste af dem lægger vi mennesker ikke mærke til. Men det er disse forbindelser, der holder naturens fine balance ved lige. Med udgangspunkt i de nyeste videnskabelige opdagelser og sine egne mange års erfaring som skovfoged viser Peter Wohlleben os, hvordan forskellige dyr, planter, floder, sten og vejrsystemer arbejder sammen, og hvad der er på spil, hvis disse delikate systemer kommer ud af balance. Jordens økosystemer er for komplekse til, at vi kan putte dem i kasser og formulere simple regler for årsag og virkning, men ”Naturens hemmelige netværk” giver os en chance for at få et indblik i naturens indre systemer og uventede makkerskaber. Og jo mere lys, der bliver kastet på forholdet mellem arterne, jo mere fascinerende bliver naturens hemmelige netværk.

Ukrudt er planter, som med deres utrolige egenskaber og sammenspil med vores insekt- og dyreliv er en kilde til glæde, oplevelser, biodiversitet og liv i haven. Ukrudt er også traditionelt planter, der er uønskede, og som igennem mange år er blevet bekæmpet og luget væk. Men hver en ukrudtsplante har sin egen historie, og vores syn på, hvilke planter der er uønskede er så småt ved at ændre sig. I denne bog har forfatteren samlet 50 af de mest interessante ukrudtsarter og fortæller planternes historie. Alle fortællingerne er smukt illustreret med de klassiske og unikke Flora Danica-tegninger.

This edited book brings together comprehensive information on various aspects of the biofortification of staple crops. It addresses the present status of food and nutritional security and highlights the importance of micronutrients in human health, a historical account of biofortification, current approaches and challenges, crop-specific biofortification efforts and various breeding approaches, including conventional, and genomics enabled improvement.  It also explains the efficacy of biofortification, bioavailability, and future thrust. It is an inclusive source of information on different aspects of micronutrients in crops of global importance.  Malnutrition is a serious global issue, with millions of people being undernourished, several suffering from micronutrient deficiencies, and the adult population struggling with obesity. Despite significant economic progress, South Asia and Sub-Saharan Africa are still home to an undernourished population. Nutrition-related health problems are related to hidden hunger and are widespread in the developing world. Women and preschool children are more vulnerable. Even though global food production has increased manifolds, estimates indicate that over 60% of the world's population is deficient in essential micronutrients such as iron, zinc, iodine, and selenium, often causing health problems and developmental delays. Linking agricultural production with human nutrition and health is crucial for ensuring nutrition security. Much research has been carried out to assess genetic diversity related to micro-nutrients in staple crops, their bioavailability, and the efficacy of biofortified germplasm. Biofortified varieties developed in different crops through conventional breeding are being up-scaled for reducing the micronutrient deficiencies in other countries.  This book is a ready reference for researchers, academicians, extension personnel, policymakers, students, and value chain stakeholders engaged in agriculture, nutrition, and health sectors promoting nutrition-sensitive diets.
