Um pássaro pequeno de coloração predominantemente marrom e preta repousa sobre um tronco coberto de musgo verde vibrante. Sua cabeça e nuca exibem um padrão intricado de manchas cinzentas e marrons, enquanto as costas e as asas são marrons com pequenas pintas amareladas. O peito é escuro, quase preto, contrastando com a barriga mais clara. Suas pernas finas e azuladas seguram firmemente o tronco, e o bico fino e alongado aponta para a direita. O olhar atento do pássaro sugere vigilância. O fundo é um borrão suave de tons verdes e marrons, indicando uma vegetação densa. Atenção: O alt da imagem foi gerado automaticamente.

📢 NEW SPECIAL ISSUE OUT!

Excited to share a special issue I co-edited on bird–window collisions, a major yet overlooked source of bird mortality

Bringing together 8 papers, this issue advances methods, evidence, and solutions to inform bird-friendly(er) built environments

This story is absolutely wild. Did you know that avocados change sex over the course of a day? And that it's controlled by a single ancient balanced polymorphism? This is flat our crazy

More work linking irregular iris pigmentation in gannets to prior HPAI infections: likelihood of NP antibody increased with iris pigment irregularity. Moderate correlations for H5 antibodies.

The Passing of the Tree of Life Web Project The Tree of Life Web Project began its journey almost 40 years ago, and was formally announced in early 1996. It has served thousands of pages of information about the evolutionary tree of life and…

The end of an era: the Tree of Life Web Project is going dark after 3 decades. Anyone interested in communicating phylogeny online should read David's account of goals, history, and future. @bembidion.bsky.social

Well, it's official. After our paper last year (onlinelibrary.wiley.com/doi/full/10....), the Slender-billed Curlew is officially declared Extinct today.

Genomic resistance in historical clinical isolates increased in frequency and mobility after the age of antibiotics Antibiotic resistance is frequently observed shortly after the clinical introduction of an antibiotic. Whether and how frequently that resistance occurred before the introduction is harder to determin...

What was antibiotic resistance like before we ever used antibiotics? How did we change what antibiotic resistance genes looked like over 100 years?

On the left, Moreau is shown speaking at a podium, wearing glasses and a patterned jacket, gesturing with her hands. On the right, text reads “Corrie Moreau – Teaching Evolution through Museum Exhibits.” Logos for Vanderbilt Evolutionary Studies and the National Center for Science Education appear at the bottom, along with a small photo of framed butterfly specimens in a museum display.

Old maps and dead birds reveal the story of grassland and bird decline in the Nilgiris Since the mid-1800s, the Nilgiris have lost 80% of their grasslands, a new study finds by comparing a colonial-era map with satellite images.
