More pumas (Puma concolor) does not change perceptions: The mismatched response of ranchers to the presence of a top carnivore

open access: yesPeople and Nature, EarlyView.
Abstract Human‐wildlife conflicts (HWCs) are one of the most critical conservation challenges worldwide. Large carnivores are frequently at the centre of these conflicts because of the perceived and real threats they pose to livestock and human safety.

Massive Binary Black Holes in the Cosmic Landscape

open access: yes, 2009
Binary black holes occupy a special place in our quest for understanding the evolution of galaxies along cosmic history. If massive black holes grow at the center of (pre-)galactic structures that experience a sequence of merger episodes, then dual black

Birth of massive black hole binaries [PDF]

open access: yes, 2007
If massive black holes (BHs) are ubiquitous in galaxies and galaxies experience multiple mergers during their cosmic assembly, then BH binaries should be common albeit temporary features of most galactic bulges.

Elliptical Galaxies and Bulges of Disk Galaxies: Summary of Progress and Outstanding Issues

open access: yes, 2015
This is the summary chapter of a review book on galaxy bulges. Bulge properties and formation histories are more varied than those of ellipticals. I emphasize two advances: 1 - "Classical bulges" are observationally indistinguishable from ellipticals ...

Malignant melanoma of the urethra: a rare histologic subdivision of vulvar cancer with a poor prognosis [PDF]

open access: yes, 2012
Malignant melanoma of the urethra is a rare tumour that is difficult to diagnose and treat, resulting in a poor prognosis. In this paper, we present the case of a 65-year-old woman who was referred to a gynaecologist because of a urethral mass that ...

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Gravitational recoils of supermassive black holes in hydrodynamical simulations of gas rich galaxies

open access: yes, 2011
We study the evolution of gravitationally recoiled supermassive black holes (BHs) in massive gas-rich galaxies by means of high-resolution hydrodynamical simulations.
