Aridity mediates the above‐ and below‐ground biodiversity–ecosystem stability relationship

open access: yesEcography, EarlyView.
Understanding the macroecological drivers of biodiversity and ecosystem stability, i.e. the ability of an ecosystem to maintain its structure and function, is crucial to inform how ecosystems can be managed and conserved effectively. Here, we conducted a field survey of plant and soil biota (bacteria, fungi, and nematodes) and estimated the temporal ...

Unveiling vertical migration patterns of the mesopelagic fish Ceratoscopelus warmingii in cold seep ecosystems: A trophic niche perspective

open access: yesEcological Indicators
Ceratoscopelus warmingii, a common mesopelagic fish in cold seep ecosystems, plays a crucial role in transferring energy and materials between different water layers, thereby influencing deep-sea carbon cycling and storage.

Parasitoid insects unveil complex patterns of functional change across elevational bands

open access: yesEcography, EarlyView.
Climate change is rapidly reshaping how insects interact with their environment, potentially disrupting ecosystem complexity and essential functioning. While functional homogenisation has been extensively investigated for charismatic insect taxa, particularly pollinators, the response of parasitoids remains largely overlooked.

Niche overlap and resource partitioning among five sympatric bufonids (Anura, Bufonidae) from northeastern Argentina [PDF]

open access: yesPhyllomedusa: Journal of Herpetology, 2009
The niche overlap and resource partitioning were analyzed for five sympatric bufonids from Northeastern Argentina: Rhinella schneideri, R. bergi, R. fernandezae, R. granulosa, and Melanophryniscus cupreuscapularis.

Dieta, selectividad y solapamiento trófico entre las tallas del pez blanco Menidia humboldtiana (Atheriniformes: Atherinopsidae) en el embalse Tiacaque, México Diet, selectivity and trophic overlap between the sizes of Silverside Menidia humboldtiana (Atheriniformes: Atherinopsidae) in the reservoir Tiacaque, Mexico

open access: yesRevista de Biología Tropical, 2013
Menidia humboldtiana es una especie nativa muy apreciada por su delicado sabor. Se determinó el espectro trófico, selectividad y solapamiento trófico de ésta, durante 1995 (épocas del año), se obtuvieron muestras de zooplancton e identificaron a nivel ...

Microvascular Abnormalities in Adolescents With Anorexia Nervosa: Nailfold Video Capillaroscopic Evidence at Acute and Remission States

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective Chronic malnutrition, hypothermia, and hormonal imbalance in anorexia nervosa (AN) may impair capillary structure and perfusion. This study aimed to describe the nailfold videocapillaroscopy (NVC) findings in adolescents with AN and atypical AN (AAN), to assess their association with Raynaud's phenomenon (RP), and evaluate ...

An integrated assessment of niche partitioning reveals mechanisms of coexistence between mesocarnivores

open access: yesGlobal Ecology and Conservation
Species diversity depends on the capacity of species to coexist, and when these share similar ecological requirements some degree of partitioning of the ecological niche is expected.

Soil‐derived, gut‐dominant generalist bacteria shape the fitness of folivorous larvae

open access: yesiMeta, EarlyView.
Whether Lepidoptera harbor a conserved core gut microbiome has long remained contentious. Through large‐scale microbiome profiling of folivorous larvae, their host plants, and associated soils across three climatically distinct regions of China, we identify two soil‐derived generalist bacteria, Ralstonia insidiosa and Delftia sp., that colonize 97.92 ...

Effect of the riparian vegetation removal on the trophic network of Neotropical stream fish assemblage

open access: yesRevista Ambiente & Água, 2018
The study of the diet of fish is an important tool to assess different levels of environmental degradation, since the availability of food in the environment is a key factor for the fish occurrence.

Geriatric Regenerative Medicine: Mechanisms, Strategies, and Clinical Translation

open access: yesiNew Medicine, EarlyView.
The pathological drivers of aging—stem cell exhaustion, cellular senescence with SASP, and aged extracellular matrix—are precisely targeted by three corresponding mechanism‐based strategies: stem cell therapies (rejuvenation, regeneration, and replacement), senolytic/senomorphic agents (D + Q, fisetin, vaccines, and CAR‐T), and senescence‐targeting ...
