What Are the Phylogenetic Limits to Pollinator Diversity?

open access: yesJournal of Applied Entomology, Volume 149, Issue 5, Page 697-703, June 2025.
ABSTRACT Although huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and ...

Effects of androgenic gland ablation on growth, sexual characters and spermatogenesis of the white shrimp, Litopenaeus vannamei (Decapoda: Penaeidae) males

open access: yes, 2016
This research was implemented to study the effects of androgenic gland ablation in the white shrimp Litopenaeus vannamei to explore sex reversal potential as an alternative technology for monosex female mariculture based on the sex dimorphic growth of ...

Macrogenetics Approach Reveals Spatial Trends and Drivers of Mitochondrial Genetic Diversity at Different Biological Organization Levels in Tropical Western Atlantic Decapods

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
There is a knowledge gap concerning the genetic diversity distribution across marine invertebrates, and whether the latitudinal genetic diversity gradient results from congruent intraspecific trends. Our results indicate higher genetic diversity in lower latitudes is correlated to productivity and oxygen levels, but does not represent the accumulation ...

Unlikely allies: Camel crickets play a role in the seed dispersal of an Asian autotrophic shrub

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 3, Page 494-501, May 2025.
Dust seeds, which are minute and contain minimal energy reserves, are often associated with heterotrophy (plants that obtain carbon without photosynthesis). Consequently, previous studies have mainly focused on the relationships between dust seeds and heterotrophy. However, dust seeds are also found in green plants.

Deep‐sea food‐web structure at South Sandwich Islands (Southern Ocean): net primary production as a main driver for interannual changes

open access: yesEcography, Volume 2025, Issue 5, May 2025.
Food‐webs are a major component of ecosystems and determinant for their functioning and structure. The food chain length (FCL) is a key feature of food‐webs and it is crucial for the resistance of the community to external stressors. The Southern Ocean (SO) food‐web is known for being short and dominated by an Antarctic krill Euphausia superba surplus,
