Growing concern about biodiversity loss underscores the need to quantify and understand temporal change. Here, we review the opportunities presented by biodiversity time series, and address three related issues: (i) recognizing the characteristics of temporal data; (ii) selecting appropriate statistical procedures for analysing temporal data; and (iii) inferring and forecasting biodiversity cha...
The ability to address land degradation and biodiversity loss while maintaining the production of plant and animal products is a key global challenge. Biodiversity decline as a result of vegetation clearance, cultivation, grazing, pesticide and herbicide application, and plantation establishment, amongst other factors, has been widely documented in agricultural ecosystems. In this paper we iden...
Biodiversity declined markedly over the past 150 years, with the biodiversity loss in fluvial ecosystems exceeding the global average. River restoration now aims at flood safety while enhancing biodiversity and has had success locally. However, at the scale of large river distributaries, the recovery remained elusive. We quantify changes in biodiversity of protected and endangered species over ...
Biodiversity continues to decline, despite the implementation of international conservation conventions and measures. To counteract biodiversity loss, it is pivotal to know how conservation actions affect biodiversity trends. Focussing on European farmland species, we review what is known about the impact of conservation initiatives on biodiversity. We argue that the effects of conservation are...

Biodiversity — the variety of all life, from genes and species to ecosystems — is intimately linked to Earth’s climate and, inevitably, to climate change. Biodiversity and poverty are also inextricably connected. For instance, changes to natural ecosystems influence both climate change and people’s ability to cope with some of its damaging impacts. And in their turn climate change, as well as p...
Land use and related pressures have reduced local terrestrial biodiversity, but it is unclear how the magnitude of change relates to the recently proposed planetary boundary ("safe limit"). We estimate that land use and related pressures have already reduced local biodiversity intactness--the average proportion of natural biodiversity remaining in local ecosystems--beyond its recently proposed ...
The rate of species loss today is approaching catastrophic levels. Scientists project that over the next two decades, more than one million species of plants and animals will become extinct. E.O. Wilson has estimated, ‘‘The rate of loss may exceed 50,000 a year, 137 a day...this rate, while horrendous, is actually the minimal estimate, based on the species/area relationship alone....’’ (Kellert...
Co-extinctions should be regarded as fundamental co-evolutionary events promoting species turnover, prior than a consequence of human induced biodiversity loss. Focusing on current scenarios is key to biodiversity conservation, but predicting future trends could be harder and less fruitful than trying to get a better grasp on the past.
