The light intensity mediates the pollination efficacy of a Caatinga morning glory Ipomoea bahiensis (Convolvulaceae)

open access: yesSociobiology, 2021
Pollination is an ecological process that relies on the matching traits of flower visitors and flowers. Morphology, behavior, and temporal patterns play essential roles in mediating the interactions between plants and floral visitors. This study analyzed

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...

Under the Shade of a Coolabah Tree: A Second Cache of Tulas From the Boulia District, Western Queensland

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.

Crab spiders (Araneae: Thomisidae) in flowering plants in a Brazilian "Cerrado" ecosystem

open access: yesBrazilian Journal of Biology
Although crab spiders are common in flowering plants, their relations with plant species and its floral traits have been poorly known in the Neotropics. Observations regarding plant habits, floral visitors and also floral characteristics such as anthesis,

Exotic flower visitors exploit large floral trait spaces resulting in asymmetric resource partitioning with native visitors [PDF]

open access: yesFunctional Ecology, 2017
Abstract Exotic species often cause severe alterations in native communities due to their ability to rapidly and efficiently utilize a broad spectrum of resources. In flower–visitor interactions, the breadth of resource use by native and exotic animals as well as the partitioning of resources among them is often estimated based on the number of ...

Body donor programs in Australia and New Zealand: Current status and future opportunities

open access: yesAnatomical Sciences Education, Volume 18, Issue 3, Page 301-328, March 2025.
Abstract Body donation is critical to anatomy study in Australia and New Zealand. Annually, more than 10,000 students, anatomists, researchers, and clinicians access tissue donated by local consented donors through university‐based body donation programs. However, little research has been published about their operations.

Indonesian inquiry: A narrative of biocultural teaching on Sulawesi Utara

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Using phenomenology, narrative inquiry and autoethnographic approaches, this study analyses a program of faculty development conducted alongside the delivery of an international field school. Through this study, we explore the value and benefits of inter‐cultural field programming and how these might serve to complement or to redress ...
