<p>Background: The Monachinae, or southern seals, are one of two subfamilies within the Phocidae and are home</p><p>to iconic pinnipeds such as the leopard seal, a fierce Antarctic top predator, and the Mediterranean monk ...
Resum: Les molleres pirinenques, aiguamolls d’alta muntanya, han estat pasturades des d’antic. Actualment són freqüents les molleres amb símptomes de sobrepastura, sobretot per la freqüentació de ramats bovins. La sobrepastura ...
Metallothioneins (MTs) are central to metal metabolism and contribute to organismal adaptation to variable metal bioavailability across ecosystems. Although well studied in chordates and mollusks, MTs remain poorly ...
<p><strong>Background</strong></p><p>Several intercellular signalling pathways (including wingless (Wnt), hedgehog (Hh), and bone morphogenetic protein (BMP)) are used repeatedly in animals throughout development and ...
Understanding holobiont dynamics is essential for unraveling the complex interactions between marine hosts and their microbiota. Sea urchins play pivotal roles in shaping benthic ecosystems, yet the functional roles of ...
The malacological faunae of two algal habitats with different lighting conditions—a sciophilous wall and a photophilous one—both located in Tossa de Mar (Costa Brava, Girona, NE Spain), have been studied to examine the ...
Many pinniped populations precipitously declined during the 19th and 20th centuries due to overharvesting. In Uruguay, the South American sea lion (SASL) was harvested until 1986. Birth rates in two nearby breeding colonies ...
Rationale: The use of accurate, species-specific diet-tissue discrimination factors is a critical requirement when applying stable isotope mixing models to predict consumer diet composition. Thus, diet-to-female and ...
Trace elements accumulate in epidermis, liver, kidney and muscle tissues in cetaceans. However, contrarily to internal tissues, epidermis can be sampled using minimally-invasive techniques. We investigate the patterns of ...
Marine predators may undergo remarkable dietary changes through time as a result of both anthropogenic and natural changes in the environment, but this variability is often difficult to tackle and seldom incorporated into ...
The Mediterranean is a semi-enclosed sea subject to high mercury (Hg) pollution from both natural and anthropogenic sources. With the objective of discerning temporal changes in marine Hg pollution in the oceanic waters ...
The breeding performance of predators is influenced by the differential consequences of prey density, prey biomass and effective consumption rates. Using camera traps at nests, we investigated whether changes in prey ...
Goniodorididae is a family of small dorid nudibranchs distributed worldwide that feed on entoprocts, ascidians, and bryozoans. The evolutionary relationships between its taxa have been uncertain due to the limited taxa ...
Corals and gorgonians play an important role as ecosystem engineers in many sublittoral communities worldwide. However, coral populations are being increasingly impacted by human activities. Active ecological restoration ...
A handful of Sphagnum species and their ecosystems find their southernmost occurrence in the Pyrenees, and these small, relict units are endangered through anthropic activities and climatic change. A number of hydropower ...
The spider genus Dysdera has undergone a remarkable diversification in the oceanic archipelago of the Canary Islands, with ~60 endemic species having originated during the 20 million years since the origin of the archipelago. ...
Since the early 2000s, understanding gene function in invertebrates has become approachable through genomics (Smith and Eyre-Walker, 2002; Clark et al., 2007). Some years later, high-throughput DNA and RNA sequencing became ...
Motivation: Gene clusters, defined as a set of genes encoding functionally related proteins, are abundant in eukaryotic genomes. Despite the increasing availability of chromosome-level genomes, the comprehensive analysis ...
Background: The compound eyes of insects exhibit extensive variation in ommatidia number and size, which affects how they see and underlies adaptations in their vision to different environments and lifestyles. However, ...
Conservation genomic studies in non-model organisms generally rely on reduced representation sequencing techniques based on restriction enzymes to identify population structure as well as candidate loci for local adaptation. ...
