Clinical chemistry retains its position as a cornerstone of toxicological assessment, yet inter-laboratory variability in baseline values remains a challenge for the integration and interpretation of multisite datasets. This study leveraged a publicly available clinical chemistry database to assess the impact of inter-laboratory variability in response to hydrazine-induced steatosis. Seventeen clinical chemistry and physico-ch...

Purpose This study aimed to determine whether a series of repeated maximal voluntary apnoeas is effective in improving subsequent time trial performance in competitive level track and field athletes. Methods Seventeen competitive runners volunteered for this study and based on their preferred competitive distance they were placed either in the 200 m (5 male, 4 female) or 1000 m group (3 male, 5 female). On two separate occasio...

We examined the age and growth of the Pacific goliath grouper ( Epinephelus quinquefasciatus ) from 210 samples collected from the main fish markets in Panama and Colombia. Ages from otoliths ranged from young‐of‐the‐year to 13 years, predominantly between 1 and 4 years. The von Bertalanffy growth parameters were L∞ = 207 cm, k = 0.13 year −1 and t 0 = −1.87 years. Instantaneous mortality rates ( Z ) were estimated at 36% in C...

Recreational fisheries represent a socially, ecologically, and economically significant component of global fisheries. The U.S. Inland Creel and Angler Survey Catalog (CreelCat) database includes inland recreational fisheries survey data across the United States to facilitate large‐scale analyses. However, because survey methods differ, a statistical method capable of integrating these surveys is necessary to assess patterns a...

Global climate change during the Late Pleistocene periodically encroached and then released habitat during the glacial cycles, causing range expansions and contractions in some species. These dynamics have played a major role in geographic radiations, diversification and speciation. We investigate these dynamics in the most widely distributed of marine mammals, the killer whale ( Orcinus orca ), using a global data set of over...

Many wide‐ranging mammal species have experienced significant declines over the last 200 years; restoring these species will require long‐term, large‐scale recovery efforts. We highlight 5 attributes of a recent range‐wide vision‐setting exercise for ecological recovery of the North American bison ( Bison bison ) that are broadly applicable to other species and restoration targets. The result of the exercise, the “Vermejo Stat...

Aim To examine the role of previously described biogeographical boundaries in shaping phylogeographical relationships within and among two putative eastern Pacific sibling species, the flag cabrilla, Epinephelus labriformis and the Clipperton grouper, Epinephelus clippertonensis (Serranidae). Location Tropical Eastern Pacific (TEP). Methods Sequence data from the mitochondrial cytochrome b gene were obtained from samples throu...

The last tropical connection between Atlantic and Indian–Pacific habitats closed c . 2 million years ago (Ma), with the onset of cold‐water upwelling off southwestern Africa. Yet comparative morphology indicates more recent connections in several taxa, including reef‐associated gobies (genus Gnatholepis ). Coalescence and phylogenetic analyses of mtDNA cytochrome b sequences demonstrate that Gnatholepis invaded the Atlantic du...
