The~ 400 million specimens deposited across~ 3000 herbaria are essential for:(i)
understanding where plants have lived in the past,(ii) forecasting where they may live in the …

All life forms across the globe are experiencing drastic changes in environmental conditions
as a result of global climate change. These environmental changes are happening rapidly …

Since the first half of the twentieth century, evolutionary theory has been dominated by the
idea that mutations occur randomly with respect to their consequences. Here we test this …

Anthropogenic habitat loss and climate change are reducing species' geographic ranges,
increasing extinction risk and losses of species' genetic diversity. Although preserving …

Global climate change (GCC) increasingly threatens biodiversity through the loss of species,
and the transformation of entire ecosystems. Many species are challenged by the pace of …

Global change has become a central focus of modern biology. Yet, our knowledge of how
anthropogenic drivers affect biodiversity and natural resources is limited by a lack of …

Recent theory and empirical evidence have provided new insights regarding how
evolutionary forces interact to shape adaptation at stable and transient range margins …

During the last centuries, humans have transformed global ecosystems. With their temporal
dimension, herbaria provide the otherwise scarce long‐term data crucial for tracking …

Background How species can adapt to abrupt environmental changes, particularly in the
absence of standing genetic variation, is poorly understood and a pressing question in the …

Herbarium specimens have long been a cornerstone of taxonomic research but are only
recently being recognized for their potential as a source of spatially and temporally …
