Conteúdo: Ecological restoration is critical to counteract land degradation and mitigate climate change. Tropical forest restoration offers major carbon sequestration potential due to rapid biomass accumulation and high storage capacity. However, the long-term carbon sequestration efficacy of different methods remains poorly understood in large-scale restoration projects. We investigated the recovery of aboveground biomass (AGB) and soil organic carbon (SOC) over a 15-year chronosequence in the Amazonia-Cerrado transition, comparing direct seeding techniques (broadcast, holes and rows) against seedling planting and natural regeneration. Using linear mixedeffects models, we assessed how restoration age and edaphoclimatic variables influenced these carbon pools. Our results show that AGB accumulation was primarily driven by the restoration age and soil fertility, with rowseeding significantly outperforming other seeding techniques and seedling plantations. This success was linked to the mechanical precision of row-seeding, which favored longer-lived pioneer species with specific seed traits. In contrast, SOC stocks remained stable across the chronosequence and were controlled by edaphoclimatic factors rather than restoration methods, underscoring the decoupling of aboveground biomass accumulation from belowground carbon dynamics. We conclude that direct seeding is a highly cost-effective method for carbon-focused restoration, but the specific technique and soil fertility significantly influenced the outcome. To maximize sequestration at scale, future efforts should prioritize soil amelioration, seeding precision, and species selection.</description>

      <description>Título: Brazil’s science–policy effort to monitor native vegetation restoration.
Autoria: GILES, A. L.; FREITAS, M. G.; ESPADA, A. L. V.; CONSTANTINO, P.; FRANCISCO, B. S.; RODRIGUES, S. B.; SAMPAIO, A. B.; FREITAS, I. F. de; BUENO, G. C. S.; LACERDA, R. C. A.; EDSON JÚNIOR, R.; SILVIUS, K.; VIEIRA, D. L. M.
Conteúdo: In its early years, the UN Decade on Ecosystem Restoration has mobilized unprecedented global commitments. Yet, measuring restoration success remains contested, particularly in megadiverse countries where the absence of standardized indicators and assessment protocols often leads to subjective decisions by environmental agencies. Here, we present a core set of leading indicators developed through a pioneering Brazil-led science–policy collaboration between environmental agencies and research institutions. The indicators capture early vegetation recovery within four years and whether restoration trajectories are sustained or at risk of reversal. The initiative also establishes a framework that bridges science and policy to deliver practical monitoring tools. It offers a model for other megadiverse countries with complex governance, showing how simple, standardized indicators can translate restoration pledges into measurable results for the UN Decade.</description>

Conteúdo: O presente trabalho descreve os efeitos do estágio reprodutivo (animais impúberes, adultos não-gestantes e gestantes), posição anatômica do ovário (direito e esquerdo) presença de corpo lúteo funcional, peso do ovário e número de folículos antrais superficiais (FAS) sobre o número de folículos pré-antrais (FPA) isolados mecanicamente. Os FPA isolados foram divididos em 3 classes a saber: primordiais, primários e secundários. O número médio (± EP) de FPA isolados por ovário foi de 1.324 ± 193; 866 + 170 e 779 ± 139, respectivamente para ovários oriundos de animais impúberes, não-gestantes e gestantes, sendo observada diferença significativa somente entre animais impúberes e gestantes. A posição anatômica do ovário (exceto para os animais não-gestantes) e a presença ou ausência de corpo lúteo não exerceram nenhum efeito sobre o número e distribuição dos FPA isolados. De um modo geral, o número de folículos primários e secundários foi negativamente correlacionado com o peso ovariano. Já o número de folículos primordiais e secundários foi, respectivamente, positiva e negativamente correlacionado com o número de FAS. Analisando as categorias de animais isoladamente, observou-se que, nos animais impúberes, o número de folículos primordiais foi positivamente correlacionado com o número de FAZ, enquanto que o número de folículos primários e secundários foi negativamente correlacionado com o número de FAS. No tocante à categoria de animais gestantes, o número de folículos primários foi negativamente correlacionado com o peso ovariano. Dependendo da categoria de ovários estudada, foram observadas associações significativas entre o número de folículos primordiais, primários e secundários. [Mechanical isolation of caprine preantral follicles at different reproductive stages and ovarian situation]. Abstract: The aïm of this study was to describe the effects of reproductive stages (pre-pubertal, non-pregnant and pregnant adult animals), ovarian anatomic position (left or right), presence of functional corpus luteum, ovarian weight and number of superficial antral follicles on the number of preantral follicles mechanically isolated. The mean number (mean ± SEM) of isolated preantral follicles per ovary was 1,324 ± 193, 866 ±170 and 779 ± 139, respectively for prepubertal, non-pregnant and pregnant adult animals. Anatomic position (except for nonpregnant animals) and the presence or absence of corpus luteum dia nof affect the number and distribution of isolated preantral follicles. In general, the number of primary and secondary follicles was negatively correlated with the ovarian weight. The numbers of primordial and secondary follicles were, respectively, positively and negatively correlated with the number of superficial antral follicles. Analyzing animal categories separately, it was observed that in prepurbetal animals, the number of primordial follicles was positively correlated with the number of superficial antral follicles. However the numbers of primary and secondary follicles were negatively correlated with the number of superficial antral follicles. In the category of pregnant animals, the number of primary follicles was negatively correlated with the ovarian weight. According to ovary category analyzed, were observed significant correlation between the number of primordial, primary and secondary isolated follicles.</description>

Autoria: RODRIGUES, A. P. R.; AMORIM, C. A.; LUCCI, C. M.; FIGUEIREDO, J. R. de; GONCALVES, P. B. D.; BEM, A. R. de
Conteúdo: Com o objetivo de isolar mecanicamente folículos pré-antrais caprinos, 52 ovários de cabras sem raça definida (SRD) foram coletados em matadouros ou extraídos por ovariectomia. O protocolo utilizado para o isolamento dos folículos, denominado procedimento mecânico direto (PMD), consistiu no corte do tecido ovariano em pequenos fragmentos, utilizando-se um cortador de tecidos. Em seguida, os fragmentos obtidos foram dissociados mecanicamente com pipetas de pasteur (1600mm e 600mm de diâmetro) e a suspensão resultante, contendo os fragmentos ovarianos, foi sucessivamente filtrada em malhas de náilon (500mm e 100mm). A realização deste procedimento permitiu isolar um número médio (± EP) de 1.067 ± 160 folículos por ovário. Com a finalidade de aumentar o número de folículos pré-antrais isolados por ovário, foi utilizado um procedimento mecânico complementar (PMC), que consistiu em submeter os fragmentos retidos nas malhas de 500mm e 100mm às etapas descritas no PMD. A utilização desses fragmentos resultou em um incremento médio de 5,2% no total de folículos isolados por ovário. O número médio (± EP) de folículos isolados por ovário, utilizando-se o procedimento mecânico (PMD + PMC), foi 1.126 + 163. Independentemente do procedimento utilizado, observou-se uma grande variação individual no número de folículos isolados por ovário. Os limites mínimo e máximo desta variação foram 53 e 7.482 folículos, respectivamente. O tamanho dos folículos isolados variou de 15,0mm a 92,7mm. É viável a utilização do procedimento mecânico, descrito pela primeira vez, para o isolamento de folículos ovarianos pré-antrais caprinos. [Mechanical isolation of ovarian preantral follicles in the goat]. Abstract: For mechanical isolation of caprine preantral follicles, ovaries from 52 undefinined breed type goats were collected at a local slaughterhouse or cirurgically extracted. The method used for preantral follicle isolation was a direct mechanical procedure (DMP). Briefly, ovaries were cut into small fragments using a tissue chopper adjusted to 500mm. The ovarian fragments were suspended 80 times with a pasteur pipette and then, the suspension was filtered successively through 500 and 100mm nylon mesh filters. The DMP resulted in a large number of isolated preantral follicles. On average, 1,067 ± 160 (mean number ± SEM) preantral follicles were isolated per ovary. To increase the number of preantral follicles recovered per ovary, the ovarian fragments remaining in the 500 and 100mm nylon mesh filters were transferred to the tissue chopper, and the procedure was repeated (complementary mechanical procedure - CMP). The use of CM P resulted in a mean increment of 5.2% of the total preantral follicles isolated per ovary. The mean number (mean ± SEM) of follicles isolated per ovary using the mechanical procedure (DPM + CPM) was 1,126 + 163. Irrespective of the procedure used, the number of preantral follicles isolated was characterized by extreme individual variation. The limits minimum and maximum of this variation were 53 and 7,482, respectively. The diameter of follicles isolated showed a range from l5.0mm to 92.7 mm. In conclusion, these results showed, for the first time, that preantral follicles can be successfully isolated from caprine ovary by applying a mechanical procedure.</description>
