Legendary conservationists show us that we still have the power to prevent critical consequences of the sixth extinction in this game changing book Can we save threatened animals and ecosystems in the midst of a mass extinction The answer is a resounding yes Before They Vanish shows us how In this wise and impassioned book renowned conservation scientists Paul R Ehrlich Gerardo Ceballos and Rodolfo Dirzo urge us to shift our thinking rather than succumb to grief over the losses that humanity faces This comprehensive look at a crucial but often overlooked aspect of conservation population extinction or the loss of a species within a specific geographic location guides us onto a new hopeful path The authors argue that conservationists have placed too much emphasis on the extinction of entire species which occurs gradually enough that we only detect it in the direst of cases By that time meaningful action may be impossible By shifting our focus to identifying extinction threats at the more localized population level we can intervene more rapidly and effectively to prevent broader declines before it s too late This change in perspective represents a critical step in saving these vanishing species early detection and intervention may be our last best ho

El Museo Nacional de Ciencias Naturales dedica esta exposición al naturalista Alfred Russel Wallace (1823-1913), para conmemorar el bicentenario de su nacimiento. Wallace fue un eminente naturalista, un avezado explorador, un cientifico creativo, y un prolifico escritor en temas muy diversos. Sus principales contribuciones a la ciencia incluyen no solo la descripcion de nuevas especies de insectos y aves, sino tambien esta- blecer las bases teoricas para comprender la distribucion geografica de las especies y la evolucion de los seres vivos. Actualmente es considerado el padre de la biogeografia como ciencia, y codescubridor con Charles Darwin de la teoria de la evolucion a traves de la seleccion natural. Aunque su imagen ha sido en parte ensombrecida por la omnipresente figura de Darwin, Wallace fue uno de los principales cientificos del siglo XIX. Con esta muestra se pretende dar a conocer su importante legado y restablecer su relevante posicion como cientifico, asi como su determinante papel a la hora de promulgar la teoria evolutiva, con- cepto unificador de la biologia que cambiaria nuestra forma de ver la vida en el planeta y nuestro lugar en el universo

In Lost Wonders author and journalist Tom Lathan tells the powerful stories of ten species that have lived died out and been declared extinct since the turn of the twenty first century Many scientists believe that we are currently living through the Earth s sixth mass extinction with species disappearing at a rate not seen for tens of millions of years a trend that will only accelerate as climate change and other pressures intensify What does it mean to live in such a time And what exactly do we lose when a species goes extinct In a series of fascinating encounters with subjects that are now nowhere to be found on Earth from giant tortoises to minuscule snails the size of sesame seeds from ocean hopping trees to fish that wag their tails like puppies Lathan brings these lost wonders briefly back to life and gives us a tantalising glimpse of what we have lost within our own lifetime Drawing on the personal recollections of the people who studied these species as well as those who tried but ultimately failed to save them and with beautiful illustrations Lost Wonders is an intimate portrait of the species that have only recently vanished from our world and an urgent warning to hold on all the more tightly to those now slipping from our grasp Illustrated

It is well known that infrastructure development projects can boost the economy and reduce the cost of trade in both developing and developed economies however infrastructure projects can also cause biodiversity loss This book is the result of an important biodiversity survey conducted along an East African railway in Tanzania The building of the railway still under construction has already led to habitat loss habitat degradation and landscape change which may have affected biodiversity The book includes recommendations to mitigate the effect of railway construction by protecting biodiversity and ecosystem services which could have major implications across Africa and other regions The area covered by the survey focuses on the Standard Gauge Railway SGR running through the Pugu and Ruvu South Forest Reserves towards Maktupora Dodoma plus data on large mammals through to Isaka Shinyanga The Pugu forests boast high biodiversity of both flora and fauna some of which are endemic to the area There are both plant and animal species that are of major conservation concern so there is urgent need to consolidate information to help formulate suitable conservation measures The data collected covers plants invertebrates amphibians birds and mammals for terrestri
