Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Contrasted habitat selection among Eurasian curlew populations according to landscape heterogeneity and breeding stage

open access: yesThe Journal of Wildlife Management, EarlyView.
This study aimed to quantify the spatio‐temporal use of breeding environments by the Eurasian curlew in 5 contrasting agricultural landscapes. To this end, 64 individuals were tagged with GPS devices to assess their space use according to their breeding stages and define their foraging habitat selection.

Substrate use and selection in sympatric intertidal hermit crab species

open access: yesBrazilian Journal of Biology, 2002
Coexisting hermit crabs may competitively interact for shells and microhabitats, mainly when shell availability is habitat-related. Three species of Clibanarius (C. antillensis, C. sclopetarius, and C.

Enhanced Weathering and Erosion of a Cohesive Shore Platform Following the Experimental Removal of Mussels

open access: yesFrontiers in Marine Science, 2021
The organisms inhabiting intertidal platforms can affect their weathering and erosion rates. Research on biotic influences on platform integrity has traditionally emphasized the role of bioeroders (i.e., organisms that scrap or bore into platforms via ...

Diablo Canyon power plant site ecological study Quarterly Report no. 22: October 1 - December 31, 1978 [PDF]

open access: yes, 1979
Field work for this quarter consisted of completion of random 1/4-m2 subtidal stations from the summer sampling season. In addition, one permanent subtidal station was surveyed. No intertidal stations were surveyed.

Thermal reaction norms and the scale of temperature variation: latitudinal vulnerability of intertidal Nacellid limpets to climate change [PDF]

open access: yes, 2012
The thermal reaction norms of 4 closely related intertidal Nacellid limpets, Antarctic (Nacella concinna), New Zealand (Cellana ornata), Australia (C. tramoserica) and Singapore (C.

Comparing non‐staining methods with Mutvei's solution to visualize growth increments in short‐lived intertidal marine gastropod shells

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...

Stable isotopes reveal minimal spatial and temporal variation in diet of the wrymouth (Cryptacanthodes maculatus)

open access: yesEcosphere, 2022
Predation by infaunal and epibenthic predators is often an important determinant of marine soft‐bottom community structure. The role of the predatory, benthic‐dwelling fish, the wrymouth (Cryptacanthodes maculatus), in the soft‐bottom food web has ...

Impacto de depredadores y niveles de recursos sobre rasgos fisiológicos de Fissurella crassa (Archeogastropoda [PDF]

open access: yes, 2015
Indexación: Web of Science; RedalycThe effects of predators on the density of prey and their resources have been widely studied; however, there is little evidence on the effects of the predators in conjunction with the availability of resources on the ...

Cliff top habitats provide important alternative feeding resources for wading birds of conservation importance wintering on non-estuarine coasts [PDF]

open access: yes, 2014
Rocky shores and beaches are important over-wintering areas for non-estuarine waders but have rarely been studied. We examined cliff top habitat use by 6 species of wader over 75 km of coast to assess their potential value as alternative feeding sites to
