The impact of a heat and moisture exchange mask on respiratory symptoms and airway response to exercise in asthma

John Dickinson, Anna Jackson, James Hull, James Hopker, Hannah Fletcher, William Gowers & John Molphy
Respiratory symptoms, including cough are prevalent in asthmatic individuals when exercising. This study investigates whether a heat and moisture exchanger (HME) face mask is effective in modulating exercise induced bronchoconstriction (EIB) and post exercise cough in a cold, dry environment in asthmatic individuals. Twenty-six participants diagnosed with asthma (20 males, 6 females) completed three cycling exercise challenges (EX) at 8 oC and 24% relative humidity (RH) in a randomised order. Participants wore either an HME...

Habitat loss alters effects of intransitive higher-order competition on biodiversity: a new metapopulation framework

Jinbao Liao, Yinglin Li, Daniel Bearup & Jinbao Liao
Recent studies have suggested that intransitive competition, as opposed to hierarchical competition, allow more species to coexist. Furthermore, it is recognized that the prevalent paradigm, which assumes that species interactions are exclusively pairwise, may be insufficient. More importantly, whether and how habitat loss, a key driver of biodiversity loss, can alter these complex competition structures and therefore species coexistence remain unclear. We thus present a new simple yet comprehensive metapopulation framework which can account for...

Drivers of amphibian population dynamics and asynchrony at local and regional scales

Hugo Cayuela, Richard A. Griffiths, Nurul Zakaria, Jan W. Arntzen, Pauline Priol, Jean-Paul Léna, Aurélien Besnard & Pierre Joly
Identifying the drivers of population fluctuations in spatially distinct populations remains a significant challenge for ecologists. Whereas regional climatic factors may generate population synchrony (i.e., the Moran effect), local factors including the level of density-dependence may reduce the level of synchrony. Although divergences in the scaling of population synchrony and spatial environmental variation have been observed, the regulatory factors that underlie such mismatches are poorly understood. Few previous studies have investigated how density-dependent processes and...

Data from: Bat ensembles differ in response to use zones in a tropical biosphere reserve

Natalie Yoh, Isham Azhar, Katheryn V. Fitzgerald, Rieka Yu, Tenaja Smith-Butler, Azniza Mahyudin & Tigga Kingston
Biosphere reserves, designated under The United Nations Education, Scientific and Cultural Organization’s (UNESCO) Man and Biosphere Programme, aim to sustainably integrate protected areas into the biological and economic landscape around them by buffering strictly protected habitats with zones of limited use. However, the effectiveness of biosphere reserves and the contribution of the different zones of use to protection is poorly known. We assessed the diversity and activity of bats in the Crocker Range Biosphere Reserve...
