The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Of all shapes and sizes: a theoretical framework for animal‐mediated terrestrial heterogeneity across scales

Ecography, EarlyView.
Animals redistribute elements throughout their lives by depositing wastes and carcasses. Growing evidence shows that these zoogeochemical processes enhance landscape diversity and heterogeneity worldwide. We provide a descriptive framework for understanding how direct animal depositions (i.e.

Improving Transparency in IDIQ Contracts: A Comparison of Common Procurement Issues Affecting Economies Across the Atlantic and Suggested Solutions [PDF]

arXiv, 2021
Expansions in the size and scope of public procurement across the Atlantic have increased calls for accountability of democratic governments. Indefinite Delivery, Indefinite Quantity contracts by their very nature are less transparent but serve as major tools of public procurement in both the European and American economies. This paper utilizes a cross-

Protecting threatened species and music traditions

Frontiers in Ecology and the Environment, EarlyView.
Musical instruments are indispensable to music traditions worldwide and often made from natural materials derived from species that are increasingly endangered. International trade threatens the survival of some of these species, as addressed by their inclusion in the UN Convention on International Trade in Endangered Species of Wild Fauna and Flora ...

Integrating climate change, biological invasions, and infectious wildlife diseases

Frontiers in Ecology and the Environment, EarlyView.
Climate change is likely to affect infectious diseases that are facilitated by biological invasions, with repercussions for wildlife conservation and zoonotic risks. Current invasion management and policy are underprepared for the future risks associated with such invasion‐related wildlife diseases. By considering evidence from bioclimatology, invasion

Favolaschia in remnants of the Atlantic Forest, Brazil

Mycoscience, 2014
The examination of recent collections of Favolaschia from remnants of the Atlantic Forest, Brazil, resulted in the identification of F. aurantiaca, F. cinnabarina and F. luteoaurantiaca sp. nov. Internal transcribed spacer (ITS) sequences obtained from these collections were introduced into the previously published phylogenetic tree of the genus to ...

Real‐world comparative effectiveness and safety of Pertuzumab in patients with HER2+ metastatic breast cancer: A pan‐Canadian population‐based cohort study

International Journal of Cancer, EarlyView.
What's New? In Canada, complexities surrounding provincial cancer care and data access challenge the collection of robust multijurisdictional real‐world evidence (RWE) on cancer therapies. RWE, however, can provide critical insight into the safety and effectiveness of novel therapies. Here, for the Canadian Real‐world Evidence for Value of Cancer Drugs

The affective, cognitive, and social benefits of interacting with nature

Journal of Consumer Psychology, EarlyView.
Abstract The surrounding environment influences how people feel, think, and behave. This effect is apparent when examining the multitude of ways interactions with natural environments impact people psychologically. In this Research Dialogue, we discuss work by ourselves and others that demonstrate the benefits of spending time in nature or interacting ...

Global Climate network evolves with North Atlantic Oscillation phases: Coupling to Southern Pacific Ocean [PDF]

, 2013
We construct a network from climate records of atmospheric temperature at surface level, at different geographical sites in the globe, using reanalysis data from years 1948-2010. We find that the network correlates with the North Atlantic Oscillation (NAO), both locally in the north Atlantic, and through coupling to the southern Pacific Ocean.
