Vertebrate pollinators are increasingly threatened worldwide, but little is known about the
potential consequences of declining pollinator populations on plants and ecosystems. Here …

Extinctions beget further extinctions when species lose obligate mutualists, predators, prey,
or hosts. Here, we develop a conceptual model of species and community attributes …

Mutualisms–cooperative interactions among different species–are known to influence global
biodiversity. Nevertheless, theoretical and empirical work has led to divergent hypotheses …

As the most remote archipelago in the world, the Hawaiian Islands are home to a highly
endemic and disharmonic biota that has fascinated biologists for centuries. Forests are the …

Deforestation and land‐use change in tropical regions result in habitat loss and extinction of
species that are unable to adapt to the conditions in agricultural landscapes. If the …

The western or European honey bee (Apis mellifera) is the primary managed pollinator in
US agricultural systems, and its importance for food production is widely recognized …

Research in ecological networks has developed impressively in recent years. A significant
part of this growth has been achieved using networks to represent the complexity of …

Nectarivorous birds and bird-pollinated plants are linked by a network of interactions. Here I
ask how these interactions influence evolution and community composition. I find near …

Human colonization of islands has resulted in the reduction or loss of many native species,
and the introduction of non‐native species, producing novel ecosystems. The impacts of …

Understanding the reproductive biology of rare plant species is fundamental to managing
their restoration. Brighamia insignis is a critically endangered Hawaiian lobeliad endemic to …
