Did you know that the bees that need saving are NOT honeybees?

Honeybees are the dairy cows of bees. People brought them over from Europe to make us honey.

The problem with honeybees, esp in resource-limited ecosystems (like hey! cities!) is that they compete with our native bees for food.

โ€˜They pushed so many lies about recyclingโ€™: the fight to stop big oil pumping billions more into plastics Plastic production has doubled over the last 20 years โ€“ and will likely double again. For author Beth Gardiner, metal water bottles and canvas tote bags are not the solution. So what is?

โ€œ[People in the plastics industry] are very happy for us to look at ourselves and at each other, and not look at them,โ€ says @bethgardiner.bsky.social, author of "Plastic Inc: Big Oil, Big Money and the Plan to Trash our Future."

A phylogeny of Afrotheria, showing stellar's sea cow, rock hyrax, african elephant, manatee, mastodon

What I love about molecular phylogeny: it's so counter-intuitive.

What's the closest living relative of elephants?
Is it rhinos?
Nope, it's a hyrax, or a manatee.

They're all in super-order Afrotheria.

Decline in body mass in adult (left) and nestling great tits. In the nestling plot, the purple line represents all nestling and the green line those that recruited to the population as breeders. Their different slope suggest an increase in the strength of selection on nestling mass something confirmed in the MS by analysing the temporal trends in selection differentials (see link for further information)

This strange little bird is an 'oystercatcher', one of 12 species in family Haematopodidae, Latin for "blood foot" because of dark red coloration on the legs of some.

A conceptual diagram illustrating the two approaches used to
assess the IUCN Red List status of specialist oil-collecting bees. The
starting point for both approaches is the compilation of georeferenced
occurrence data for the species. Here, we use Rediviva vogeli as an
example. IUCN-based approach (top sequence, left to right): To
estimate the Extent of Occurrence (EOO), a minimum convex hull
polygon is plotted around the occurrence records. The resulting EOO
map is then intersected with national spatial datasets to evaluate the
decline in the โ€œarea, extent, and/or quality of habitat,โ€ corresponding
to Subcriterion b(iii) of IUCN Criterion B. First, the EOO is reduced
to 59.4% of its initial area as a consequence of habitat loss. Overlaying threatened habitats on what remains reveals that 29.1% of remaining habitat is threatened, suggesting a high risk of further habitat loss.
Finally, we overlay the EOO with the current protected area network
and find that only 5.6% of the EOO is currently protected. SDM-based
approach (bottom sequence, left to right): Occurrence data and environmental variables are used to generate species distribution models
(SDMs), from which the Area of Occupancy (AOO) is estimated. The
resulting AOO map is also intersected with national spatial datasets to
assess habitat condition under Subcriterion b(iii) of Criterion B. First,
the AOO is reduced to 67.4% of its initial area as a consequence of
habitat loss. Overlaying threatened habitats on what remains reveals
that 22.1% of remaining habitat is threatened, suggesting a high risk
of further habitat loss. Finally, we overlay the AOO with the current
protected area network and find that only 22.1% of the AOO is currently protected. The two approaches, combined with expert knowledge where available, informs the assessment of species status under
IUCN Criterion B: Endangered (EN) using the IUCN-approach; and
Vulnerable (VU) using the SDM-approach
