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

open access: yesJournal 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.

Transdermal drug delivery in horses: An in vitro comparison of skin structure and permeation of two model drugs at various anatomical sites

open access: yesVeterinary Dermatology, Volume 34, Issue 3, Page 235-245, June 2023., 2023
Background – Oral and parenteral drug delivery in horses can be difficult. Equine‐specific transdermal drug formulations offer improved ease of treatment; development of such formulations requires a deeper understanding of the structural and chemical tissue barrier of horse skin. Hypothesis/Objectives – To compare the structural composition and barrier

Floristic diversity, composition and dominance across Amazonian forest types respond differently to latitude

open access: yesJournal of Biogeography, Volume 50, Issue 4, Page 685-698, April 2023., 2023
Abstract Aim The latitudinal biodiversity gradient is considered a first‐order biogeographical pattern for most taxonomic groups. Latitudinal variation in plant diversity is not always consistent, and this could be related to the particular characteristics of different forest types.

Communities of endophytic fungi in a Puerto Rican rainforest vary along a gradient of disturbance due to Hurricane Maria

open access: yesEcology and Evolution, Volume 12, Issue 12, December 2022., 2022
Even more than a year after the catastrophic passage of Hurricane Maria, communities of endophytic symbionts in a Puerto Rican rainforest bear a signature of forest disturbance. Abstract Increases in the frequency and intensity of hurricanes influence the structure, function, and resilience of Caribbean forests.

Pigment molecular composition reveals significant information for visual communication

open access: yesFunctional Ecology, Volume 36, Issue 11, Page 2756-2762, November 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Melanins are the most common pigments in vertebrates and, as such, fufill multiple adaptive functions, including honest signalling. This is the case of male pied flycatchers Ficedula hypoleuca, whose dorsal plumage, composed of black and grey feathers pigmented by ...

Structural and compositional dimensions of phytochemical diversity in the genus Piper reflect distinct ecological modes of action

open access: yesJournal of Ecology, Volume 110, Issue 1, Page 57-67, January 2022., 2022
Crude extract 1H NMR diversity synthesizes the compositional diversity and structural complexity of phytochemical mixtures. Plants can develop chemical diversity through different combinations of structural and compositional biosynthetic mechanisms; thus, methods incorporating both dimensions of phytochemical diversity can provide new theoretical ...
