Calibración in situ del sensor cosmos para determinar humedad del suelo en escalas intermedias (~1 km)

Terra Latinoamericana, 2013
La heterogeneidad del suelo influye ampliamente en el contenido de humedad, dificultando la precisa determinación de este parámetro en estudios con fines hidrológicos y ecológicos que requieren de mediciones continuas y representativas para escalas ...

Mosquito population dynamics are shaped by interactions among larval density, temperature, and relative humidity. [PDF]

Ecology
Abstract Understanding how variation in key abiotic and biotic factors interact at ecologically relevant spatial scales is crucial for predicting population dynamics, distributions, and abundances. This is especially true for vectors that transmit human pathogens.

Effects of interactions between anthropogenic stressors and recurring perturbations on ecosystem resilience and collapse. [PDF]

Conserv Biol, 2023
Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests. [PDF]

New Phytol
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Microbial drivers of root plasticity. [PDF]

New Phytol
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Respuesta del ajo a un gradiente de humedad [PDF]

Ingeniería e Investigación, 1989
El presente trabajo consistió en conocer la respuesta en el rendimiento del ajo (Allium Sativum L.) a diferentes niveles de humedad, utilizando para ello la metodología del riego por gradiente, con un diseño experimental de bloques completos al azar. Con

A prospective study evaluating the correlation between local weather conditions, pollen counts and pruritus of dogs with atopic dermatitis. [PDF]

Vet Dermatol
Abstract Background Canine atopic dermatitis (cAD) is a hereditary, generally pruritic and predominantly T‐cell‐driven inflammatory skin disease, involving an interplay between skin barrier abnormalities, allergen sensitisation and microbial dysbiosis.

Seasonality regulates the structure and biogeochemical impact of ectomycorrhizal fungal communities across environmentally divergent neotropical dry forests

Journal of Ecology, Volume 111, Issue 8, Page 1598-1613, August 2023., 2023
These results highlight the importance of seasonality and plant community composition in shaping different aspects of SDTF ECM fungal community structure and diversity as well as the potential for both the plant and fungal components of ECM symbioses to impact soil functioning across heterogenous SDTFs.

Climate and microhabitat shape the prevalence of endozoochory in the seed rain of tropical montane forests

Biotropica, Volume 55, Issue 2, Page 408-417, March 2023., 2023
We investigated the effects of climate and microhabitat conditions on the prevalence of endozoochorous plant species in the seed rain of tropical montane forests in southern Ecuador. Our analyses demonstrate that the prevalence of endozoochorous plant species in seed rain increases with temperature across elevations and with leaf area index within ...
