Persistent anthrax as a major driver of wildlife mortality in a tropical rainforest [PDF]

open access: yes, 2017
Anthrax is a globally important animal disease and zoonosis. Despite this, our current knowledge of anthrax ecology is largely limited to arid ecosystems, where outbreaks are most commonly reported.

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

open access: yesBiological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...

The Meanings of Chimpanzee Gestures [PDF]

open access: yesCurrent Biology, 2014
Chimpanzees' use of gesture was described in the first detailed field study [1, 2], and natural use of specific gestures has been analyzed [3-5]. However, it was systematic work with captive groups that revealed compelling evidence that chimpanzees use gestures to communicate in a flexible, goal-oriented, and intentional fashion [6-8], replicated ...

Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

The malagarasi river does not form an absolute barrier to chimpanzee movement in Western Tanzania. [PDF]

open access: yesPLoS ONE, 2013
The Malagarasi River has long been thought to be a barrier to chimpanzee movements in western Tanzania. This potential geographic boundary could affect chimpanzee ranging behavior, population connectivity and pathogen transmission, and thus has ...

Utterance evolution: the road to generative, combinatorial communicators

open access: yesBiological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

Chimpanzee [PDF]

open access: yes, 2020
The chimpanzee is one of our planet's best-loved and most instantly recognisable animals. Splitting from the human lineage between four and six million years ago, it is (along with its cousin, the bonobo) our closest living relative, sharing around 94% of our DNA.

Serological cross-reactivity between Merkel cell polyomavirus and two closely related chimpanzee polyomaviruses. [PDF]

open access: yesPLoS ONE, 2014
Phylogenetic analyses based on the major capsid protein sequence indicate that Merkel cell polyomavirus (MCPyV) and chimpanzee polyomaviruses (PtvPyV1, PtvPyV2), and similarly Trichodysplasia spinulosa-associated polyomavirus (TSPyV) and the orangutan ...
