Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group‐level processes such as subgroup formation and fission–fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing coh...

This is the second of three papers dealing with metal-bearing circumneutral mine drainage from the inactive Rico-Argentine mine site located at an elevation of ≈ 2740 m (9000 feet) in the San Juan mountain range in southwestern Colorado. This paper evaluates two years of mine drainage treatment using a passive system that included a vertical-flow engineered biotreatment cell. The collapsed St. Louis Tunnel (SLT) discharges cir...

Managing wildlife populations in the face of global change requires regular data on the abundance and distribution of wild animals, but acquiring these over appropriate spatial scales in a sustainable way has proven challenging. Here we present the data from Snapshot USA 2020, a second annual national mammal survey of the USA. This project involved 152 scientists setting camera traps in a standardized protocol at 1485 location...

Lycopodium clavatum sporopollenin exine capsules (SpECs) are known to both adsorb and absorb chemicals. The aim of the present work was to determine whether oestradiol (E2) is ‘bioavailable’ to bioindicator species, either pre-adsorbed to, or in the presence of, SpECs. SpEC uptake was confirmed for Daphnia magna and Dreissena bugensis . E2 levels varied among treatments for Caenorhabditis elegans though there was no relationsh...

A literature review was conducted to determine the barriers and facilitators to shellfish cultivation using Northern Ireland ( NI ) as a case study. This review included 23 papers, published in 14 journals, indexed in the Web of Science database. The eligibility criteria included (i) peer‐reviewed articles or websites from key government or agency stakeholders in the aquaculture supply chain; (ii) had a primary focus on shellf...

7Massive fires in Indonesian peatlands in the 1990s and in eastern Russian peatlands in 2002 and last year have highlighted the need to manage forests overlying peat deposits, as well as converted peat forests and open peatlands. Peat or peaty soils, contain 65% or more of partially decayed vegetation, can burn freely or underground. They cover some 10 percent of worldwide forests and contain 25 percent of all terrestrial carb...

Summary The dissimilatory metal‐reducing bacterium, Shewanella oneidensis MR‐1 produced γ‐MnS (rambergite) nanoparticles during the concurrent reduction of MnO 2 and thiosulfate coupled to H 2 oxidation. To investigate effect of direct microbial reduction of MnO 2 on MnS formation, two MR‐1 mutants defective in outer membrane c ‐type cytochromes (Δ mtrC /Δ omcA and Δ mtrC /Δ omcA /Δ mtrF ) were also used and it was determined...
