Optimising daily sampling of plant–bee interaction networks

Journal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

Integrative Zoology, EarlyView.
Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

Integrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.

Water Use Behavior of Individual Birds: Ring Ouzels in an Arid High‐Mountain Ecosystem

Integrative Zoology, EarlyView.
Water is a limiting resource for birds in arid ecosystems. Individual birds differ strongly in how they use shared water sources, with drinking behavior increasing with temperature. Behavioral differences, hierarchy, and social context ultimately shape unequal access to water within the population. ABSTRACT Water availability strongly constrains animal

Morphotype Bias, Morph Specific Recruitment and No Elevation‐Life History Relation in High Altitude Mesquite Lizard Populations

Integrative Zoology, EarlyView.
Site‐level differences in population growth (λ) and phenotype frequencies. Mountain silhouettes represent the three study sites. Morph relative abundances are shown in the colored vertical bar. Point estimates and confidence intervals of λ for each site are displayed below, with the dashed line marking the threshold for demographic stability (λ = 1 ...

Cosmología, biología y origen del alma en al-Fārābī y Avicena

Ideas y Valores, 2019
Se discute cómo pueden dos filósofos islámicos sostener que la generación del cuerpo es necesaria para que se origine el alma y, al mismo tiempo, afirmar que ésta puede separarse del cuerpo, ya sea transformándose en un intelecto inmaterial ‒en el caso ...

Parasites at the Summit: Unexpected Geographic Distribution of the Blood Parasite Lineage Found in the Endangered Giant Lizard of Tenerife

Integrative Zoology, EarlyView.
We combined microscopic screening and molecular phylogenetic analyses to characterize blood parasites infecting Gallotia intermedia from the coastal cliffs of Montaña de Guaza and to place these infections in a broader biogeographic context. We detected apicomplexan parasites of the genus Karyolysus infecting 53.6% of G.

Metabarcoding replicate detection frequency tracks ddPCR copy number for cod and herring eDNA in ancient marine sediments

Methods in Ecology and Evolution, EarlyView.
Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...
