A long-term assessment of the multidisciplinary degree of multidisciplinary journals.

Are multidisciplinary journals truly multidisciplinary, and, how has the multidisciplinary character of these journals evolved over the long term? Here, we assess these questions by analyzing data from the Journal Citation Reports. We examined 983,246 articles and reviews published between 1980 and 2021 in 127 journals categorized under 'Multidisciplinary Sciences'. We found that the representation of the main branches of knowledge in multidisciplinary journals was uneven and, in general, not proportional to the global research effort dedicated to each branch.

Physiological and morphological characterization of endangered European wildcats from the Iberian lineage: Reference values for conservation.

The European wildcat (Felis silvestris), particularly its Iberian lineage, is experiencing an important population decline due to various threats. For this reason, we started in 2017 an intensive monitoring of a population of this species in southeastern Spain. To determine their physiological status, we conducted health checks on wildcats during 2017-2023.

Host defense peptides in crocodilians - A comprehensive review.

Amphibians and reptiles, like all animals, are prone to periodic infections. However, crocodilians stand out for their remarkable ability to remain generally healthy and infection-free despite frequent exposure to a wide variety of microorganisms in their habitats and often sustaining significant injuries. These animals have evolved highly active immune mechanisms that provide rapid and effective defense.

Serum Biochemical Profile, Intestinal and Liver Histomorphometry of Captive Broad-Snouted Caiman (Caiman latirostris) Fed With a Diet Enriched With Soybean (Glycine max).

The impact of plant-based diets on crocodilians is unclear. Serum profiles and histomorphometry provide valuable insights into their nutritional and physiological status. This study aims to elucidate the impact of three levels of soybean meal substitution combined chicken by-product minced on the growth and health of broad-snouted caiman (Caiman latirostris).

Freshwater megafauna shape ecosystems and facilitate restoration.

Freshwater megafauna, such as sturgeons, giant catfishes, river dolphins, hippopotami, crocodylians, large turtles, and giant salamanders, have experienced severe population declines and range contractions worldwide. Although there is an increasing number of studies investigating the causes of megafauna losses in fresh waters, little attention has been paid to synthesising the impacts of megafauna on the abiotic environment and other organisms in freshwater ecosystems, and hence the consequences of losing these species. This limited understanding may impede the development of policies and actions for their conservation and restoration.
