Estuarine ecosystems are threatened by anthropogenic pressures such as climate change, coastal development, and increased nutrient and sediment inputs. These pressures are deteriorating ecological health and threatening the functioning and services that estuarine ecosystems provide. Here, we conducted a pilot study to assess the initial recovery capacity of highly eutrophic intertidal estuarine sediments. We theorised that the...

In arid and semi-arid regions, where water is scarce and climatic variability is high, monitoring changes in irrigated land is essential for ensuring food security and building resilience. However, few studies have assessed irrigation dynamics in the Horn of Africa using remote sensing, and empirical data from Eritrea remain limited. This study investigates the spatio-temporal dynamics of irrigated agriculture in two contrasti...

Intestivirids (order Crassvirales, family Intestiviridae ), viruses that infect Bacteroidales bacteria in the mammalian gastrointestinal tract, have been identified as a highly abundant component of the healthy human virome that may shape patterns of human health and disease through direct action on the microbiome. While double‐stranded DNA bacteriophages called crAssphages ( Carjivirus communis ) that infect bacteria in the B...

Male reproductive competition can select for condition‐dependent, conspicuous traits that signal some aspect of fighting ability and facilitate assessment of potential rivals. However, the underlying mechanisms that link the signal to a male's current condition are difficult to investigate in wild populations, often requiring invasive experimental manipulation. Here, we use digital photographs and chest skin samples to investi...

Coastal waterways can be significant sources of the potent greenhouse gas nitrous oxide (N 2 O) due to nitrogen inputs and eutrophication. Here, we quantify groundwater derived N 2 O inputs and atmospheric emissions within a modified urban embayment (Sydney Harbour, Australia). Overall, we found low N 2 O saturation (91–171%) and air–water fluxes (−2.2 to 24.6 μ mol m −2 d −1 ). Concentrations were highest in upstream brackish...

Urban and agricultural development of coastal catchments is known to increase dissolved nitrogen inputs into estuaries; however, much less is known about how land use influences the production of the powerful greenhouse gas nitrous oxide (N 2 O). Here, we assess dissolved N 2 O dynamics in four nearby estuaries across a regional land use gradient and summarize the literature to put the observations into global perspective. Dur...

The molar of a giant deer, Megaloceros giganteus (Blumenbach, 1799), was discovered in sandy deposits of the North Sea, about 10 km west of the present shoreline of the Netherlands. Compacted masticated plant remains were preserved in the molar's deep folds. A palaeoecological analysis of these plant remains shows the complete dominance of pollen from Artemisia (sage) and other Asteraceae Tubuliflorae (Compositae), indicating...
