Planktonic foraminifera
No full textPlanktonic foraminifera are marine protozoa with a calcareous and chambered test. The group evolved since late Early Jurassic, and from mid-Cretaceous onward, it has significantly proliferated and is a major component of oceanic oozes. Planktonic foraminifera phylogeny often is closely linked to paleoceanographic turn-over events, and its detailed biostratigraphy contributes significantly to Earth’s geologic history

Cheilolejeunea nana Schuster (1978: 426), syn. fide Bastos & Gradstein (2020) Cheilolejeunea oncophylla (Ångstrom 1876: 86) Grolle & Reiner (1997: 781), syn. fide Bastos & Gradstein (2020) Plants light brown to almost yellowish, 0.6–0.9 mm wide. Stems in cross section 60–100 µm in diameter, 7–8 epidermal cells, 113–25 × 18–29 µm; 10–16 medullary cells, 9–18 × 5–11 µm. Ventral merophytes 2 cells wide. Leaves distant to contiguous, ovate to ovate, slightly concave, 330–410 × 240–330 µm; margin entire, apex rounded to obtuse, dorsal margin curve; cells slightly mammillose on the dorsal side and with a low papilla, conspicuous trigones; basal cells 18–27 × 12–18 µm, median cells 17–27 × 12–20 µm, marginal cells 10–18 × 9–16 µm. Lobules inflated, ovate to rectangular, 1/3–2/5 of leaf length, free margin involute, apical tooth acute formed by a long cell, 15–22 × 9–15 µm, keel arched, crenate by mammillose cells. Underleaves distant, orbicular to ovate, 130–200 × 120–170 µm, 1.5–2.5 × stem width, bifid to 1/3 to 1/2, with a V-shaped sinus, margin entire, base cuneate. Autoicous or dioicous. Androecia axillary or terminal, 1–3 pairs of bracts. Gynoecia with pycnolejeuneoid innovations, bracts obovate, 510–550 × 300– 330 µm, apex acute, lobule 300 × 100 µm, bracteole ovate, 390–420 × 350–450 µm, bifid to 1/3. Perianth 5-keeled, generally with very strong keels, beak long. Distribution and habitat:—Neotropical, occurring in Caribbean islands, Costa Rica, Colombia, Venezuela, Peru, Bolivia, Brazil, and Argentina (Bastos 2017, Grolle & Reiner- Drehwald 1999). This species is widely distributed in the study area, growing as an epiphyte on tree trunks and branches, in the inter-Andean desert and in semi-desert vegetation, lowland rainforest, lower and upper montane rainforests, grass páramos, and shrub and cushion páramos, between 200–4000 m, in the Guatuso-Talamanca, Puntarenas-Chiriquí, Guajira, Magdalena, and Cauca provinces of the Pacific dominion, and in the Páramo province of SATZ (Fig. 13). Notes:—A variable species, characterized by leaves slightly concave, the apex rounded to obtuse, cells mammillose on the dorsal side whit a low papilla (see Gradstein 2021, Gradstein & Bastos 2022), with conspicuous trigones, and underleaves distant, small 1.5–2 × width stem, bifid up to 1/3, base cuneate, and occasionally with vegetative reproduction by branches caducous (Grolle & Reiner-Drehwald 1997). This species can be confused with C. acutangula (see Gradstein & Bastos 2021) but the latter has usually acute leaf apices (not rounded to obtuse) and larger underleaves, 2.5–4 × stem width (not 1.5–2×).

Governance and economic growth
No full textBecause protection of property rights cannot be appropriated by any individual, it is widely recognized as being the state's responsibility. Moreover, recent empirical evidence suggests that protection of property rights leads to higher investment levels and faster growth. The extent of property rights protection differs significantly across countries. The author integrates the emergence of property rights within a simple growth framework. Drawing on North (1990), he presents a model where economic performance and enforcement of property rights may reinforce each other.Initial conditions determine the economy's convergence to a high-income or a low-income steady state. Existing empirical evidence offers tentative support for this theory.Judicial System Reform,Labor Policies,Economic Theory&Research,Environmental Economics&Policies,Common Property Resource Development,Economic Theory&Research,Inequality,Common Property Resource Development,Environmental Economics&Policies,Governance Indicators
Phylogeny, taxon circumscriptions, and character evolution in the core Ptychanthoideae (Lejeuneaceae, Marchantiophyta)
No full textPhylogenetie relationships and character evolution in the core Ptychanthoideae (Lejeuneaceae, Marchantiophyta), with a focus on Thysananthus, are assessed based on molecular (plastid psbA-trnH, trnG, trnL-F, trnS-rps4, nrITS), morphological-anatomical, and phytochemical data. Generic relationships are molecularly well-resolved and confirm the placement of Mastigolejeunea pancheri and the monotypic Dendrolejeunea fruticosa in Thysananthus. Most morphological characters currently used to distinguish genera in Ptychanthoideae are homoplastic according to ancestral state reconstruction. Molecular and phytochemical data suggest the occurrence of polyphyletic species in Thysananthus and Mastigolejeunea. Careful study of the polyphyletic taxa revealed morphological differences between some of the intraspecific chides, which correlated with synonymized or novel species. Incongruence between plastid and ITS data in M. pancheri indicated the occurrence of a putative hybrid, the first one recorded in Lejeuneaceae and the first in liverworts inferred from phylogenetic data.Royal Thai government; German Academic Exchange Service (DAAD

Taxonomy and biostratigraphy of new and emended species of Cenozoic deep-water agglutinated foraminifera from the Labrador and North Seas
No full textDeep marine, fine grained sedimentary strata of Maastrichtian through Miocene age in the Labrador and North Sea sedimentary basins are rich in agglutinated benthic foraminifera. Six new taxa have been found in these regions, several of which also extend to other circum-Atlantic Paleogene localities. The new taxa are: Ammomarginulina aubertae, n. sp. (Maastrichtian to Eocene), Adercotryma agterbergi, n. sp. (middle Eocene to lower Oligocene), Reticulophragmoides jarvisi (Thalmann) emended herein (Paleocene to lower Oligocene), Reticulophragmoides sp. 5 (Oligocene to Miocene), and Spiroplectammina navarroana Cushman emended herein (Maastrichtian to lower middle Eocene). The last occurrences of these taxa are important elements in the high-resolution probabilistic biozonations for the Labrador and North Sea basins
The political economy of public spending on education, inequality, and growth
No full textPublic provision of education has often been perceived as universal and egalitarian, but in reality it is not. Political pressure typically results in incidence bias in favor of the rich. The author argues that the bias in political influence resulting from extreme income inequalities is particularly likely to generate an incidence bias, which we call social exclusion. This may then lead to a feedback mechanism whereby inequality in the incidence of public spending on education breeds higher income inequality, thus generating multiple equilibria: with social exclusion and high inequality; and with social inclusion and relatively low inequality. The author also shows that the latter equilibrium leads to higher long-run growth than the former. An extension of the basic model reveals that spillover effects among members of social groups differentiated by race or ethnicity may reinforce the support for social exclusion.Public Health Promotion,Environmental Economics&Policies,Decentralization,Economic Theory&Research,Health Monitoring&Evaluation,Inequality,Poverty Assessment,Governance Indicators,Achieving Shared Growth,Economic Theory&Research
