Evaluation of canine epidermis and keratinocytoids (keratinocytic organoids) by transmission electron microscopy. [PDF]

Vet Dermatol
Background – Skin disease is a common complaint in veterinary medicine. Current models often use live animals. Epidermal organoids (keratinocytoids) are 3D miniature organs created in culture from single epidermal keratinocytes. These keratinocytoids can be used as an alternative to live animal studies to investigate epidermal structures and skin ...

Caatinga diaspores: Descriptive overview of dispersal units of seasonally dry tropical forests and woodlands. [PDF]

Ecology
Abstract Dispersal unit characteristics provide crucial insights into species ecology and are essential for the conservation and restoration of ecosystems. The Caatinga, the largest ecosystem of seasonally dry tropical forests and woodlands in South America, remains underrepresented in terms of dispersal unit data, which are often scattered across the ...

Histopathological characterisation of trunk‐dominant canine pemphigus foliaceus, and comparison with classic facial and insecticide‐triggered forms

Veterinary Dermatology, Volume 34, Issue 5, Page 425-440, October 2023., 2023
Background – While the clinical features were described recently, the histopathological characterisation of trunk‐dominant canine pemphigus foliaceus (PF) is lacking, and whether it differs from classic facial or insecticide‐triggered PF is unknown. Hypothesis/Objectives – This study describes the histopathological findings of trunk‐dominant PF, and ...

3D pollination biology using micro‐computed tomography and geometric morphometrics in Theobroma cacao

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Thermoregulatory ability and mechanism do not differ consistently between neotropical and temperate butterflies

Global Change Biology, Volume 29, Issue 15, Page 4180-4192, August 2023., 2023
We studied how temperate and neotropical butterflies respond to temperature change. Neotropical butterflies were better at regulating their body temperature than temperate butterflies, mainly because at high air temperatures neotropical butterflies cooled themselves more.

Forest structure predicts species richness and functional diversity in Amazonian mixed‐species bird flocks

Biotropica, Volume 55, Issue 2, Page 467-479, March 2023., 2023
We show that vegetation structure can predict species richness and functional diversity in Amazonian mixed‐species flocks in primary and secondary forests. In addition, we show that secondary forest flocks retain a large percentage of the functional diversity exhibited by their primary forest counterparts. Abstract Secondary forest has the potential to

Phylogenetic and ecological correlates of pollen morphological diversity in a Neotropical rainforest

Biotropica, Volume 53, Issue 1, Page 74-85, January 2021., 2021
Abstract Morphology varies enormously across clades, and the morphology of a trait may reflect ecological function or the retention of ancestral features. We examine the tension between ecological and phylogenetic correlates of morphological diversity through a case study of pollen grains produced by angiosperms in Barro Colorado Island, Panama (BCI ...

Influence of the irrigation in the growth Schinus terebinthifolius seedlings Influência da irrigação no crescimento de mudas de Schinus terebinthifolius

Pesquisa Florestal Brasileira, 2012
<p>Aiming to evaluate the development of seedlings of Schinus terebinthifolius under different irrigation depth, an experiment was installed in a greenhouse. The experimental design used was randomized block consisting of 4 treatments with 3 blocks.
