Despite the (TTAGG)n telomeric repeat supposed being the ancestral DNA motif of telomeres in insects, it was repeatedly lost within some insect orders. Notably, parasitoid hymenopterans and the social wasp Metapolybia decorata (Gribodo) lack the (TTAGG)n sequence, but in other representatives of Hymenoptera, this motif was noticed, such as different ant species and the honeybee. These findings raise the question of whether the insect telomeric repeat is or not phylogenetically predominant in Hymenoptera. Thus, we evaluated the occurrence of both the (TTAGG)n sequence and the vertebrate telomere sequence (TTAGGG)n using dot-blotting hybridization in 25 aculeate species of Hymenoptera. Our results revealed the absence of (TTAGG)n sequence in all tested species, elevating the number of hymenopteran families lacking this telomeric sequence to 13 out of the 15 tested families so far. The (TTAGGG)n was not observed in any tested species. Based on our data and compiled information, we suggest that the (TTAGG)n sequence was putatively lost in the ancestor of Apocrita with at least two subsequent independent regains (in Formicidae and Apidae). 相似文献

Fire is one of the commonest disturbances worldwide, transforming habitat structure and affecting ecosystem functioning. Understanding
how species respond to such environmental disturbances is a major conservation goal that should be monitored using functionally
and taxonomically diverse groups such as Hymenoptera. In this respect, we have analyzed the taxonomic and functional response
to fire and post-fire management of a Hymenoptera community from a Mediterranean protected area. Thus, Hymenoptera were sampled
at fifteen sites located in three burnt areas submitted to different post-fire practices, as well as at five sites located
in peripheral unburnt pine forest. A total of 4882 specimens belonging to 33 families, which were classified into six feeding
groups according to their dietary preferences, were collected. ANOVA and Redundancy Analyses showed a taxonomic and functional
response to fire as all burnt areas had more Hymenoptera families, different community composition and higher numbers of parasitoids
than the unburnt area. Taxonomic differences were also found between burnt areas in terms of the response of Hymenoptera to
post-fire management. In general the number of parasitoids was positively correlated to the number of potential host arthropods.
Parasitoids are recognized to be sensitive to habitat changes, thus highlighting their value for monitoring the functional
responses of organisms to habitat disturbance. The taxonomic and functional responses of Hymenoptera suggest that some pine-forest
fires can enhance habitat heterogeneity and arthropod diversity, hence increasing interspecific interactions such as those
established by parasitoids and their hosts. 相似文献

Species differ widely with regard to parental investment strategies and mechanisms underlying those strategies. The passing
of benefits to likely genetic offspring can be mediated through a number of different computational and behavioral systems.
We report results from an agent-based model in which offspring maintain proximity with parents and parents transmit benefits
to offspring without the capacity of either parent or offspring to “recognize” one another. Instead, parents follow a simple
rule to emit benefits after reproducing and offspring follow a simple rule of moving in the direction of positive benefit
gradients. This model differs from previous models of spatial kin-based altruism in that individuals are modeled as having
different behavioral rules at different life stages and benefits are transmitted unidirectionally from parents to offspring.
High rates of correctly directed parental investment occur when mobility and sociality are low and parental investment occurs
over a short period of time. We suggest that strategies based on recognition and bonding/attachment might serve to increase
rates of correctly directed parental investment under parameters that are shown here to otherwise lead to high rates of misdirected
and wasted parental investment. 相似文献

An major research area in environmental chemistry is the development of methods for the analysis of biomarkers. Metallothioneins
are used as biomarkers in studies of heavy metals exposure in water, because metallothioneins are synthesized and accumulated
when organisms are exposed to toxic concentrations of pollutants. In this work, simple and sensitive voltammetric methods
were developed for metallothionein and copper (II) determinations in fish liver Lepomis gibbosus. Both analytical methodologies were optimized and applied to samples extracted from individuals previously submitted to sub-lethal
toxicological trials with copper sulphate (CuSO4) and cadmium chloride (CdCl2). The obtained results showed that both methods are very precise, sensitive, and involve simple sample preparation processes.
Moreover, metallothioneins showed better correlation with the toxic exposure than Cu2+. To the best of our knowledge, this is the first time that hepatic metallothioneins and Cu2+ contents are voltammetrically determined in order to be compared in their function as heavy metal biological indicators. 相似文献
