The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Spider prey (Araneae) of Trypoxylon (Trypargilum) rogenhoferi (Hymenoptera: Sphecidae) in southeastern Brazil

open access: yesRevista de Biología Tropical, 2000
Fifty five nests and 216 cells of Trypoxylon (Trypargilum) rogenhoferi were obtained from trap-nests (cut bamboo canes) in Santa Carlota Farm (Itaoca Section=IS and Santana Section=SS), Cajuru and on the São Paulo University Campus, Ribeirão Preto (=RP),

Climate‐driven phenological shifts in emergence dates of British bees

open access: yesEcology and Evolution, 2023
Climate change has a diverse range of impacts on wild bees, including their phenology or timing of life history events. Climate‐driven phenological shifts can not only impact individuals at species level but also threaten the vital pollination service ...

Late Summer-Fall Solitary Wasp Fauna of Central New York (Hymenoptera: Tiphiidae, Pompilidae, Sphecidae) [PDF]

open access: yes, 2017
Eighty-one species of primarily ground-nesting solitary wasps belonging to the families Tiphiidae, Pompilidae and Sphecidae were observed, collected and identified from six sandy and gravelly study areas in Cayuga and Onondaga Counties, New York.

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

open access: yesCytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Parasitism of \u3ci\u3eAncistrocerus Antilope\u3c/i\u3e (Hymenoptera: Eumenidae) by Leucospis Affinis (Hymenoptera: Leucospididae) [PDF]

open access: yes, 2017
The chalcid wasp Leucospis affinis has been known to parasitize only megachilid bees. Its rare occurrence as a parasite of the eumenid wasp Ancistrocerus antilope indicates that eumenid wasps may be a large resource this chalcid is not ...

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Evolutionary Relationships of Courtship Songs in the Parasitic Wasp Genus, Cotesia (Hymenoptera: Braconidae) [PDF]

open access: yes, 2019
Acoustic signals play an important role in premating isolation based on sexual selection within many taxa. Many male parasitic wasps produce characteristic courtship songs used by females in mate selection.

The role of Rho GTPases in facial morphogenesis

open access: yesDevelopmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Relationships between Body Size and Parasitic Fitness and Offspring Performance of Sclerodermus pupariae Yang et Yao (Hymenoptera: Bethylidae). [PDF]

open access: yesPLoS ONE, 2016
The relationship between body size and fitness in parasitoid wasps has several effects on parasitic ability, reproductive behavior in female wasps, and progeny fitness.
