The home range of the signal crayfish in a British lowland river [PDF]

, 1997
The signal crayfish Pacifastacus leniusculus (Dana), a native of north-western North America, is now a common resident in some British fresh waters following its introduction to England in 1976 (Lowery & Holdich 1988).

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans

Integrative Zoology, EarlyView.
Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

The signal crayfish is vulnerable to both the As and the PsI-isolates of the crayfish plague

Knowledge and Management of Aquatic Ecosystems, 2014
The carrier status and possible elevated tolerance of the signal crayfish (Pacifastacus leniusculus) against the crayfish plague disease agent (Aphanomyces astaci) has been speculated for several decades.

Behavioral differences in an over‐invasion scenario: marbled vs. spiny‐cheek crayfish [PDF]

, 2018
New species often invade ecosystems already dominated by previous invaders. Ornamental freshwater crayfish, particularly parthenogenetic marbled crayfish (Procambarus virginalis), increasingly establish in European water bodies where they interact with ...

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

Animal Conservation, EarlyView.
Crayfish are a vital part of freshwater ecosystems, yet one third of assessed species are threatened with extinction, and almost 90% are highly sensitive to climate change. In this study, we produced a phylogenetically‐informed species prioritisation for crayfish conservation and explored the impacts of projected climate change scenarios on crayfish ...

Revealing the Diverse Allergenic Protein Repertoire of Six Widely Consumed Crab Species: A Species‐Specific Allergen in King Crab

Allergy, EarlyView.
This study comprehended the allergen profiles of six edible crab species using proteomic and transcriptomic analyses and identified 11 putative allergens. King crab has a distinct protein and allergen profile, with the discovery of malate dehydrogenase as a novel king crab‐specific allergen registered as Para c 11.

Food webs in forest and pasture streams in the Waikato region, New Zealand: A study based on analyses of stable isotopes of carbon and nitrogen, and fish gut contents. [PDF]

, 1997
Stable isotopes of carbon (C) and nitrogen (N) were studied in 11 stream communities in the Waikato region of New Zealand. From comparisons of mean d13C and d15N values, food webs in the shaded, forest streams were clearly based on allochthonous material

Healthcare Professional Survey on Complementary Feeding and Allergy Prevention in High‐ Versus Low‐Risk Infants: An EAACI Task Force Report

Allergy, EarlyView.
ABSTRACT Complementary feeding (CF) influences infants' long‐term dietary preferences, growth, and food allergy (FA) risk. However, guidance given to families and the implementation of FA prevention guidelines by healthcare professionals (HCPs) remain unclear.

Crayfish distribution updating in central Italy [PDF]

Knowledge and Management of Aquatic Ecosystems, 2009
Introductions of non-indigenous crayfish have received great attention from biologists and policy makers during the last decade. Purposes of this study are to update the knowledge about the crayfish distribution in Latium (central Italy), and to show how
