The fleas of house mice (Mus musculus L.) and ship rats (Rattus rattus L.) in forest of the Orongorongo Valley, New Zealand

open access: yesNew Zealand Journal of Zoology, Volume 52, Issue 3, Page 239-254, September 2025.
ABSTRACT The ectoparasites of introduced rodents in mainland New Zealand forests include several species of cosmopolitan flea that may be important in the population dynamics and future biocontrol of rodents. We describe a 2‐rodent, 2‐flea system that showed little change over 20 years.

Morphological and molecular data on the bat flies, Basilia silvae (Brèthes, 1913) and Trichobius parasiticus Gervais, 1844 parasitizing Chilean bats

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 3, Page 422-430, September 2025.
We determined morphological and molecularly two species of bat flies: T. parasiticus (Streblidae), and B. silvae (Nycteribiidae). We generated the first sequences for both species in the country for the cytochrome oxidase subunit I. We do recover monophyletic groups for both species, and we discussed the tree topology.

The complete mitochondrial genome of the rodent flea Nosopsyllus laeviceps: genome description, comparative analysis, and phylogenetic implications

open access: yesParasites & Vectors
Background Fleas are one of the most common and pervasive ectoparasites worldwide, comprising at least 2500 valid species. They are vectors of several disease-causing agents, such as Yersinia pestis.

Flea‘in Around: A Look at the Identification, Preservation, Clearing, and Mounting of Siphonaptera [PDF]

open access: yes, 2018
Fleas are remarkable and highly specialized insects, with no part of their external anatomy being easily mistaken for that of any other insect. Due to their small size, the subtle differences among the distinguishing morphological characteristics of each

Evolutionary implications of a deep‐time perspective on insect pollination

open access: yesBiological Reviews, Volume 100, Issue 4, Page 1452-1466, August 2025.
ABSTRACT Plant pollination by insects represents one of the most transformative and iconic ecological relationships in the natural world. Despite tens of thousands of papers, as well as numerous books, on pollination biology published over the past 200 years, most studies focused on the fossil record of pollinating insects have only been published in ...

Environmental and health associations with parasite presence on a coastal sentinel, the little penguin

open access: yesOikos, Volume 2025, Issue 5, May 2025.
Seabird health is linked to their marine and terrestrial environments, but health–environment relationships are rarely described. Parasites are common among seabird colonies, however reductions to seabird health may occur if the delicate parasite–host relationship is imbalanced.

The cryptonephridial/rectal complex: an evolutionary adaptation for water and ion conservation

open access: yesBiological Reviews, Volume 100, Issue 2, Page 647-671, April 2025.
ABSTRACT Arthropods have integrated digestive and renal systems, which function to acquire and maintain homeostatically the substances they require for survival. The cryptonephridial complex (CNC) is an evolutionary novelty in which the renal organs and gut have been dramatically reorganised. Parts of the renal or Malpighian tubules (MpTs) form a close
