We live amid a global wave of anthropogenically driven biodiversity loss: species and
population extirpations and, critically, declines in local species abundance. Particularly …

The human population is projected to reach 11 billion this century, with the greatest
increases in tropical develo** nations. This growth, in concert with rising per-capita …

Hunting is a major driver of biodiversity loss, but a systematic large-scale estimate of hunting-
induced defaunation is lacking. We synthesized 176 studies to quantify hunting-induced …

The number and extent of roads will expand dramatically this century. Globally, at least 25
million kilometres of new roads are anticipated by 2050; a 60% increase in the total length of …

African elephants (Loxodonta africana) are imperiled by poaching and habitat loss. Despite
global attention to the plight of elephants, their population sizes and trends are uncertain or …

Linear infrastructure such as roads, highways, power lines and gas lines are omnipresent
features of human activity and are rapidly expanding in the tropics. Tropical species are …

African forest elephants–taxonomically and functionally unique–are being poached at
accelerating rates, but we lack range-wide information on the repercussions. Analysis of the …

Infrastructures, such as roads, mines, and hydroelectric dams, are proliferating explosively.
Often, this has serious direct and indirect environmental impacts. We highlight nine issues …

Africa is on the verge of a mining boom. We review the environmental threats from African
mining development, including habitat alteration, infrastructure expansion, human migration …

As the largest frugivores on Earth, elephants have unique ecological properties. Found in
deserts, savannahs, and forests, they are the last remnants of a diverse lineage. Among the …
