Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

open access: yesInsect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Tracking hatchery and wild Atlantic salmon (Salmo salar) smolt during river exit and early marine migration to assess survival, predation risk and migration speed

open access: yesJournal of Fish Biology, EarlyView.
Abstract Significant declines in Atlantic salmon (Salmo salar) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in ...

Near‐infrared confocal imaging reveals the spatial organisation of far‐red photosynthesis in Shark Bay microbial mats and Halomicronema sp.

open access: yesJournal of Microscopy, EarlyView.
Abstract Far‐red light (FRL) cyanobacteria occupy spectrally filtered habitats where visible wavelengths are depleted but far‐red radiation persists. Shark Bay (Western Australia) stromatolitic microbial mats provide such a habitat, containing subsurface cyanobacterial communities in which chlorophyll d/f (Chl d/f)‐containing phototrophs coexist with ...

Soft cliff retreat adjacent to coastal defences, with particular reference to Holderness and Christchurch Bay, UK

open access: yes, 2008
Coastal defences reduce sediment input and modify the sediment budget, usually resulting in a sediment deficit down-drift and an accumulation up-drift. This process results in set-back adjacent to defences.

Allometric patterns in Rhamphorhynchus muensteri and their role in the paleoecology, life habits, and taxonomic framework of pterosaurs

open access: yesJournal of Anatomy, EarlyView.
The Graphical Abstract ilustrates the different allometric pattern within different Pterosauria groups, highlighting how the allometry influences the flight and habits of Pterosauria. Abstract Pterosaurs were the first vertebrates to achieve powered flight, a result of various unique anatomical adaptations, and significant morphological diversity ...

Fluctuating asymmetry based on fractal geometry does not track environmental stress in an intertidal habitat‐forming fucoid

open access: yesJournal of Phycology, EarlyView.
Abstract The availability of easy‐to‐measure and inexpensive biomarkers is a challenge for monitoring environmental stress in organisms. Although it has been proposed that non‐directional deviations from a symmetrical pattern in morphological traits (called fluctuating asymmetry.

Intraspecific Variation in Reproductive Aspects of Female Soldier Crabs, Mictyris guinotae, Between the River Mouth and Upper Reach Habitats

open access: yesMarine Ecology, EarlyView.
ABSTRACT The soldier crab, Mictyris guinotae, is a dominant intertidal crustacean associated with sand flats in the vicinity of the Urauchi River estuary on Iriomote Island, Japan. We compared various aspects of its reproductive biology at two sites (the river mouth and upper reach) on exposed bare sand flats 300 m and 3000 m upstream from the mouth ...
