Teleosemantics for neural word embeddings
Mind &Language, EarlyView.This paper applies a consumer‐based teleosemantic framework to give a detailed analysis of a particular algorithm for generating word embeddings. In the process, it addresses several of the challenges facing teleosemantic approaches to artificial neural networks.

Sexual dimorphism and morphological integration in the orchid bee brain [PDF]
Scientific ReportsAbstract Sex-specific behaviours are common across animals and often associated with sexual dimorphism in the nervous system. Using micro-CT scanning we standardized sex-specific brain atlases and tested for sexual dimorphism in the brain of the orchid bee Euglossa dilemma, a species with marked sex differences in social behaviour, mating ...

Plant Biology, EarlyView.By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...

Sympatric Speciation: Perfume Preferences of Orchid Bee Lineages [PDF]
Current Biology, 2008 Female attraction to an environmentally derived mating signal released by male orchid bees may be tightly linked to shared olfactory preferences of both sexes. A change in perfume preference may have led to divergence of two morphologically distinct lineages.

Animating blossom: Time‐lapse to encourage plant awareness in the YouTube era
PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1572-1583, September 2026.Time‐lapse videos can effectively capture key traits of flower blossoms, such as color, 3D structure, and temporal changes, making them valuable complements to herbarium specimens and other botanical collections. Despite the abundance of such videos on YouTube, most provide no ecological and botanical insights.

Is the “Centro de Endemismo Pernambuco” a biodiversity hotspot for orchid bees? [PDF]
Brazilian Journal of Biology, 2014 The orchid-bee faunas (Hymenoptera: Apidae: Euglossina) of the three largest forest remnants in the “Centro de Endemismo Pernambuco”, northeastern Brazil, namely Estação Ecológica de Murici (ESEC Murici), RPPN Frei Caneca, and a forest preserve belonging to Usina Serra Grande, in the states of Alagoas and Pernambuco, were surveyed using seventeen ...

Urban Landscape Influence Orchid Bee Diversity in a Tropical Megacity
Journal of Applied Entomology, Volume 150, Issue 8, Page 1153-1163, September 2026.ABSTRACT The increasing urbanization has affected pollinator communities, such as Euglossini bees, which play a crucial role in maintaining biodiversity through the pollination of numerous plants. However, the impact of different levels of urbanization on the diversity of these bees is still not fully understood, especially in large tropical urban ...
