The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

The Bulletin of the Ecological Society of America, Volume 107, Issue 2, April 2026.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

Chrysoperla externa (Neuroptera: Chrysopidae) as a Potential Biological Control Agent of Raoiella indica (Acari: Tenuipalpidae)

Entomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 335-342, April 2026.
First and third instar Chrysoperla externa showed efficient predatory capacity at low R. indica density, but second instar C. externa exhibits a density‐dependent predatory ability. The lacewing C. externa shows promise as a biocontrol agent for R. indica in coconut because it consumed 8362 R. indica females across all its larval instars.

Anti‐Predation and Size‐Dependent Gas Exchange Functions of Amazonian Architect Cicada Towers

Biotropica, Volume 58, Issue 2, March 2026.
Clay towers built by cicada nymphs before metamorphosis are poorly understood. We experimentally show that towers of the Amazonian cicada Guyalna chlorogena reduce predation risk and exhibit size‐dependent growth responses to gas exchange obstruction, supporting their interpretation as adaptive extended phenotypes.

Effects of light-dark cycle on the spatial distribution and feeding activity of fish larvae of two co-occurring species (Pisces: Hypophthalmidae and Sciaenidae) in a Neotropical floodplain lake

Brazilian Journal of Biology, 2018
Most studies on mechanisms regulating fish larvae processes have focused on assessing the isolated effects of food distribution and feeding behavior. However, in natural ecosystems, fish larvae may strongly interact with zooplankton organisms in an array

Influência de aléias de leguminosas arbóreas na infestação de bicho-mineiro em cafeeiro. [PDF]

, 2011
O bicho-mineiro, Leucoptera coffeella (Guérin - Mèneville, 1842) (Lepidoptera: Lyonetiidae), é talvez a principal praga do cafeeiro (Coffea spp.) na atualidade, principalmente nas regiões de temperaturas mais elevadas e de maior déficit hídrico.

Social media highlights the overlooked impact of cats on arthropods

Insect Conservation and Diversity, Volume 19, Issue 2, Page 460-465, March 2026.
The impact of domestic cats on vertebrate biodiversity is unequivocal; however, we still know little about their effects on arthropods. By analysing over 17,000 photos and videos from social media platforms (iStock and TikTok), we documented 550 predation events of cats on arthropods.

Comportamento alimentar da cobra d’água amazônica Helicops hagmanni Roux, 1910 (Reptilia: Squamata: Colubridae: Hydropsini)

Boletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2008
O gênero Helicops inclui, atualmente, 15 espécies, das quais onze ocorrem na floresta amazônica. Helicops hagmanni se alimenta de peixes e apresenta hábitos noturnos, mas dados detalhados sobre seu comportamento alimentar e ecologia são escassos.

Potencial de predação de três espécies de fitoseídeos sobre Oligonychus ilicis (McGREGOR, 1917)(Acari: Tetranychidae). [PDF]

, 2011
O ácaro-vermelho, Oligonychus ilicis (McGregor, 1917), é um dos principais ácaros fitófagos do cafeeiro (Coffea spp.), sendo responsável por causar o bronzeamento nas folhas e como conseqüência do ataque há redução da capacidade fotossintetizadora das ...

Testing the size‐grain hypothesis in a generalist predator: The case of an ant species in the Brazilian savannah

Journal of Zoology, Volume 328, Issue 3, Page 234-247, March 2026.
In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...
